===================== = End-of-Day report = ===================== Timeframe: Donnerstag 03-10-2024 18:00 − Freitag 04-10-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Cloudflare blocks largest recorded DDoS attack peaking at 3.8Tbps ∗∗∗ --------------------------------------------- During a distributed denial-of-service campaign targeting organizations in the financial services, internet, and telecommunications sectors, volumetric attacks peaked at 3.8 terabits per second, the largest publicly recorded to date. The assault consisted of a "month-long" barrage of more than 100 hyper-volumetric DDoS attacks flood. [..] Many of the attacks aimed at the target’s network infrastructure (network and transport layers L3/4) exceeded two billion packets per second (pps) and three terabits per second (Tbps). [..] The threat actor behind the campaign leveraged multiple types of compromised devices, which included a large number of Asus home routers, Mikrotik systems, DVRs, and web servers. --------------------------------------------- https://www.bleepingcomputer.com/news/security/cloudflare-blocks-largest-re… ∗∗∗ Over 4,000 Adobe Commerce, Magento shops hacked in CosmicSting attacks ∗∗∗ --------------------------------------------- Approximately 5% of all Adobe Commerce and Magento online stores, or 4,275 in absolute numbers, have been hacked in "CosmicSting" attacks. [..] The CosmicSting vulnerability (CVE-2024-34102) is a critical severity information disclosure flaw; when chained with CVE-2024-2961, a security issue in glibc's iconv function, an attacker can achieve remote code execution on the target server. [..] Sansec says that multiple threat actors are now conducting attacks as patching speed is not matching the critical nature of the situation. --------------------------------------------- https://www.bleepingcomputer.com/news/security/over-4-000-adobe-commerce-ma… ∗∗∗ Survey of CUPS exploit attempts, (Fri, Oct 4th) ∗∗∗ --------------------------------------------- It is about a week since the release of the four CUPS remote code execution vulnerabilities. After the vulnerabilities became known, I configured one of our honeypots that watches a larger set of IPs to specifically collect UDP packets to port 631. Here is a quick summary of the results. --------------------------------------------- https://isc.sans.edu/diary/rss/31326 ∗∗∗ Apple fixes bug that let VoiceOver shout your passwords ∗∗∗ --------------------------------------------- Apple just fixed a duo of security bugs in iOS 18.0.1 and iPadOS 18.0.1, one of which might cause users' saved passwords to be read aloud. It's hardly an ideal situation for the visually impaired. For those who rely on the accessibility features baked into their iGadgets, namely Apple's VoiceOver screen reader, now is a good time to apply the latest update. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2024/10/04/apple_voiceo… ∗∗∗ Sicherheitsupdates: Cisco patcht Lücken in Produkten quer durch die Bank ∗∗∗ --------------------------------------------- Neben einem kritischen Fehler kümmert sich der Netzwerkausrüster auch um einige Lücken mit mittlerem und hohem Risikograd. Patches stehen bereit. --------------------------------------------- https://heise.de/-9961998 ∗∗∗ DRAY:BREAK Breaking Into DreyTek Routers Before Threat Actors Do It Again ∗∗∗ --------------------------------------------- In 2024, routers are a primary target for cybercriminals and state-sponsored attackers – and are the riskiest device category on networks. With this knowledge, we investigated one vendor with a history of security flaws to help it address its issues and prevent new attacks. Our latest research discovered 14 new vulnerabilities in DrayTek routers. --------------------------------------------- https://www.forescout.com/resources/draybreak-draytek-research/ ∗∗∗ Threat actor believed to be spreading new MedusaLocker variant since 2022 ∗∗∗ --------------------------------------------- Talos has recently observed an attack leading to the deployment of a MedusaLocker ransomware variant known as “BabyLockerKZ.” The distinguishable techniques — including consistently storing the same set of tools in the same location on compromised systems, the use of tools that have the PDB path with the string “paid_memes,” and the use of a lateral movement tool named “checker” — used in the attack led us to take a deeper look to try to understand more about this threat actor. --------------------------------------------- https://blog.talosintelligence.com/threat-actor-believed-to-be-spreading-ne… ∗∗∗ Ransomware Groups Demystified: CyberVolk Ransomware ∗∗∗ --------------------------------------------- As part of our ongoing efforts to monitor emerging cyber threats, we have analyzed the activities of CyberVolk, a politically motivated hacktivist group that transitioned into using ransomware and has been active since June 2024. --------------------------------------------- https://www.rapid7.com/blog/post/2024/10/03/ransomware-groups-demystified-c… ∗∗∗ Google Adds New Pixel Security Features to Block 2G Exploits and Baseband Attacks ∗∗∗ --------------------------------------------- Google has revealed the various security guardrails that have been incorporated into its latest Pixel devices to counter the rising threat posed by baseband security attacks. --------------------------------------------- https://thehackernews.com/2024/10/android-14-adds-new-security-features.html ∗∗∗ Portable Hacking Lab: Control The Smallest Kali Linux With a Smartphone ∗∗∗ --------------------------------------------- Running Kali Linux on a Raspberry Pi Zero is a fantastic way to create a portable, powerful testing device. This guide will walk you through setting up Kali Linux Pi-Tail on a headless Raspberry Pi Zero 2 W that is powered and controlled from a smartphone via SSH or VNC that provides a graphical interface to your Pi-Tail. --------------------------------------------- https://www.mobile-hacker.com/2024/10/04/portable-hacking-lab-control-the-s… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (firefox, golang, linux-firmware, and thunderbird), Debian (kernel and zabbix), Fedora (firefox, pgadmin4, and php), Mageia (chromium-browser-stable, cjson, hostapd and wpa_supplicant, and openjpeg2), Oracle (firefox, flatpak, and go-toolset:ol8), Red Hat (cups-filters, firefox, grafana, linux-firmware, python3, python3.11, and python3.9), SUSE (expat, firefox, libpcap, and opensc), and Ubuntu (freeradius, imagemagick, and unzip). --------------------------------------------- https://lwn.net/Articles/992936/ ∗∗∗ Keycloak 26.0.0 released ∗∗∗ --------------------------------------------- CVE-2024-7318 - Use of a Key Past its Expiration Date in org.keycloak:keycloak-core, CVE-2024-8883 Vulnerable Redirect URI Validation Results in Open Redirect , CVE-2024-8698 Improper Verification of SAML Responses Leading to Privilege Escalation in Keycloak, CVE-2024-7254 - Stack-based Buffer Overflow in com.google.protobuf:protobuf-java --------------------------------------------- https://www.keycloak.org/2024/10/keycloak-2600-released ∗∗∗ Wordfence Intelligence Weekly WordPress Vulnerability Report (September 23, 2024 to September 29, 2024) ∗∗∗ --------------------------------------------- https://www.wordfence.com/blog/2024/10/wordfence-intelligence-weekly-wordpr… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

===================== = End-of-Day report = ===================== Timeframe: Mittwoch 25-09-2024 18:00 − Donnerstag 26-09-2024 18:00 Handler: Alexander Riepl Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Talos discovers denial-of-service vulnerability in Microsoft Audio Bus; Potential remote code execution in popular open-source PLC ∗∗∗ --------------------------------------------- Cisco Talos’ Vulnerability Research team recently disclosed two vulnerabilities in Microsoft products that have been patched by the company over the past two Patch Tuesdays. One is a vulnerability in the High-Definition Audio Bus Driver in Windows systems that could lead to a denial of service, while the other is a memory corruption issue that exists in a multicasting protocol in Windows 10. [..] For Snort coverage that can detect the exploitation of these vulnerabilities, download the latest rule sets from Snort.org, and our latest Vulnerability Advisories are always posted on Talos Intelligence’s website. --------------------------------------------- https://blog.talosintelligence.com/talos-discovers-denial-of-service-vulner… ∗∗∗ The Cyber Resilience Act, an Accidental European Alien Torts Statute? ∗∗∗ --------------------------------------------- What if someone is harmed by their own government, but the technology used against them was created by a company based in the United States?

Risks, techniques, and mitigations in hardware hacking ∗∗∗ --------------------------------------------- DMA allows input-output (I/O) devices to access memory without CPU involvement. Bypassing the Operating System (OS) by providing direct high-speed access to the system’s memory improves efficiency for Graphics processing units (GPUs), Network Interface Cards (NICs), storage devices (e.g. NVMe) and peripheral devices. DMA capable connections include PCI, PCI Express (PCIe), Thunderbolt, FireWire, ExpressCard. Without additional safeguards, DMA can make systems vulnerable to attacks. --------------------------------------------- https://www.pentestpartners.com/security-blog/direct-memory-access-dma-atta… ∗∗∗ Unraveling Sparkling Pisces’s Tool Set: KLogEXE and FPSpy ∗∗∗ --------------------------------------------- We analyze new tools DPRK-linked APT Sparkling Pisces (aka Kimsuky) used in cyberespionage campaigns: KLogExe (a keylogger) and FPSpy (a backdoor variant). --------------------------------------------- https://unit42.paloaltonetworks.com/kimsuky-new-keylogger-backdoor-variant/ ∗∗∗ Simple Mail Transfer Pirates: How threat actors are abusing third-party infrastructure to send spam ∗∗∗ --------------------------------------------- Spammers are always looking for creative ways to bypass spam filters. As a spammer, one of the problems with creating your own architecture to deliver mail is that, once the spam starts flowing, these sources (IPs/domains) can be blocked. Spam can more easily find its way into the inbox if it is delivered from an unexpected or legitimate source. Realizing this, many spammers have elected to attack web pages and mail servers of legitimate organizations, so they may use these “pirated” resources to send unsolicited email. --------------------------------------------- https://blog.talosintelligence.com/simple-mail-transfer-pirates/ ∗∗∗ Phishing and Social Engineering: The Human Factor in Election Security ∗∗∗ --------------------------------------------- Discover how phishing and social engineering threaten the 2024 U.S. elections in part three of our Election Cybersecurity series.

Exploitation is facilitated by bypassing previous patches. [..] Based on our analysis, three of these vulnerabilities are, essentially, the same vulnerability with the same root cause. Since the patch bypass we are disclosing today elaborates on those previous disclosures, we’ll outline them now. --------------------------------------------- https://www.rapid7.com/blog/post/2024/09/05/cve-2024-45195-apache-ofbiz-una… ∗∗∗ Watch the Typo: Our PoC Exploit for Typosquatting in GitHub Actions ∗∗∗ --------------------------------------------- In this blog, we explain how we managed to leverage typosquatting in GitHub Actions and got several applications with inadvertent typos to run our ‘fake’ action.

Im ersten Fall kann ein entfernter Angreifer ohne Anmeldung aufgrund von statischen Admin-Zugangsdaten auf Instanzen zugreifen. Mit den Adminrechten des Accounts erlangt ein Angreifer die volle Kontrolle.

===================== = End-of-Day report = ===================== Timeframe: Donnerstag 08-08-2024 18:00 − Freitag 09-08-2024 18:00 Handler: Robert Waldner Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Malware force-installs Chrome extensions on 300,000 browsers, patches DLLs ∗∗∗ --------------------------------------------- An ongoing and widespread malware campaign force-installed malicious Google Chrome and Microsoft Edge browser extensions in over 300,000 browsers, modifying the browsers executables to hijack homepages and steal browsing history. --------------------------------------------- https://www.bleepingcomputer.com/news/security/malware-force-installs-chrom… ∗∗∗ ‘Sinkclose’ Flaw in Hundreds of Millions of AMD Chips Allows Deep, Virtually Unfixable Infections ∗∗∗ --------------------------------------------- Researchers warn that a bug in AMD’s chips would allow attackers to root into some of the most privileged portions of a computer—and that it has persisted in the company’s processors for decades. --------------------------------------------- https://www.wired.com/story/amd-chip-sinkclose-flaw/ ∗∗∗ Windows Server durch PoC-Exploit für CVE-2024-38077 gefährdet ∗∗∗ --------------------------------------------- Nochmals ein Nachgang zum Juli 2024-Patchday, bei dem Microsoft die Schwachstelle CVE-2024-38077 im Windows-Remotedesktop-Lizenzierungsdienst (RDL) von Windows Server geschlossen hat. [..] es wurde ein Proof of Concept (PoC) für diese Schwachstelle veröffentlicht. --------------------------------------------- https://www.borncity.com/blog/2024/08/09/windows-server-durch-poc-exploit-f… ∗∗∗ How Hackers Extracted the ‘Keys to the Kingdom’ to Clone HID Keycards ∗∗∗ --------------------------------------------- [HID]s actually known about the vulnerabilities [..] since sometime in 2023, when it was first informed about the technique by another security researcher [..] HID warned customers about the existence of a vulnerability that would allow hackers to clone keycards in an advisory in January, which includes recommendations about how customers can protect themselves—but it offered no software update at that time. --------------------------------------------- https://www.wired.com/story/hid-keycard-authentication-key-vulnerability/ ∗∗∗ ICANN reserves .internal for private use at the DNS level ∗∗∗ --------------------------------------------- The Internet Corporation for Assigned Names and Numbers (ICANN) has agreed to reserve the .internal top-level domain so it can become the equivalent to using the 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16 IPv4 address blocks for internal networks. Those blocks are reserved for private use by the Internet Assigned Numbers Authority, which requires they never appear on the public internet. --------------------------------------------- https://www.theregister.com/2024/08/08/dot_internal_ratified/ ∗∗∗ New attack against the [Linux kernel] SLUB allocator ∗∗∗ --------------------------------------------- Researchers from Graz University of Technology have published details of a new attack on the Linux kernel called SLUBstack. The attack uses timing information to turn an ability to trigger use-after-free or double-free bugs into the ability to overwrite page tables, and thence into the ability to read and write arbitrary areas of memory. The good news is that this attack does require an existing bug to be usable; the bad news is that the kernel regularly sees bugs of this kind. --------------------------------------------- https://lwn.net/Articles/984984/ ∗∗∗ Fake-Videos: Van der Bellen & Assinger werben nicht für Investmentplattformen ∗∗∗ --------------------------------------------- Derzeit erleben wir erneut eine Welle von Deepfake-Videos, in denen österreichische Prominente auf Facebook und Instagram für Investmentplattformen werben. Lassen Sie sich nicht täuschen: Weder Bundespräsident Alexander van der Bellen noch TV-Moderator Armin Assinger sind plötzlich Finanzexperten, die eine Investmentplattform entwickelt haben. Die Plattformen sind betrügerisch und die Videos wurden von Kriminellen erstellt. --------------------------------------------- https://www.watchlist-internet.at/news/fake-videos-van-der-bellen-assinger-… ∗∗∗ Confusion Attacks: Exploiting Hidden Semantic Ambiguity in Apache HTTP Server! ∗∗∗ --------------------------------------------- This article explores architectural issues within the Apache HTTP Server, highlighting several technical debts within Httpd, including 3 types of Confusion Attacks, 9 new vulnerabilities, 20 exploitation techniques, and over 30 case studies. [..] These vulnerabilities were reported through the official security mailing list and were addressed by the Apache HTTP Server in the 2.4.60 update published on 2024-07-01. --------------------------------------------- https://devco.re/blog/2024/08/09/confusion-attacks-exploiting-hidden-semant… ∗∗∗ Best Practices for Cisco Device Configuration ∗∗∗ --------------------------------------------- In recent incidents, CISA has seen malicious cyber actors acquire system configuration files by leveraging available protocols or software on devices, such as abusing the legacy Cisco Smart Install feature. CISA recommends organizations disable Smart Install and review NSA’s Smart Install Protocol Misuse advisory and Network Infrastructure Security Guide for configuration guidance. --------------------------------------------- https://www.cisa.gov/news-events/alerts/2024/08/08/best-practices-cisco-dev… ∗∗∗ Sicherheitsforscher verwandeln Sonos-One-Lautsprecher in Wanze ∗∗∗ --------------------------------------------- Angreifer können über das eingebaute Mikrofon von Sonos-One-Lautsprechern Gespräche mitschneiden. Mittlerweile ist das Sicherheitsproblem gelöst. --------------------------------------------- https://heise.de/-9830061 ===================== = Vulnerabilities = ===================== ∗∗∗ Schwachstellen in 1Password gefährden MacOS-Nutzer [CVE-2024-42218, CVE-2024-42219] ∗∗∗ --------------------------------------------- In 1Password 8 für Mac klaffen zwei Sicherheitslücken, die es Angreifern ermöglichen, Tresorelemente von MacOS-Nutzern abzugreifen. [..] Damit ein Angriff gelingt, muss ein Angreifer allerdings bei beiden Lücken bereits in der Lage sein, auf dem Zielsystem eine eigene Software auszuführen. --------------------------------------------- https://www.golem.de/news/datenabfluss-moeglich-schwachstellen-in-1password… ∗∗∗ Microsoft Edge (Chromium-based) Remote Code Execution Vulnerability [CVE-2024-38219] ∗∗∗ --------------------------------------------- Successful exploitation of this vulnerability requires an attacker to gather information specific to the environment and take additional actions prior to exploitation to prepare the target environment. Fxied in Microsoft Edge Version 127.0.2651.98 released 8/8/2024. --------------------------------------------- https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-38219 ∗∗∗ Microsoft Edge (HTML-based) Memory Corruption Vulnerability [CVE-2024-38218] ∗∗∗ --------------------------------------------- The word Remote in the title refers to the location of the attacker. This type of exploit is sometimes referred to as Arbitrary Code Execution (ACE). The attack itself is carried out locally. This means an attacker or victim needs to execute code from the local machine to exploit the vulnerability. Fixed in Microsoft Edge Version 127.0.2651.98 released 8/8/2024. --------------------------------------------- https://msrc.microsoft.com/update-guide/vulnerability/CVE-2024-38218 ∗∗∗ Multiple vulnerabilities in LogSign ∗∗∗ --------------------------------------------- https://www.zerodayinitiative.com/advisories/ZDI-24-1102/ http://www.zerodayinitiative.com/advisories/ZDI-24-1103/ http://www.zerodayinitiative.com/advisories/ZDI-24-1104/ https://www.zerodayinitiative.com/advisories/ZDI-24-1105/ https://www.zerodayinitiative.com/advisories/ZDI-24-1106/ --------------------------------------------- https://support.logsign.net/hc/en-us/articles/20617133769362-07-08-2024-Ver… ∗∗∗ PostgreSQL relation replacement during pg_dump executes arbitrary SQL [CVE-2024-7348] ∗∗∗ --------------------------------------------- Time-of-check Time-of-use (TOCTOU) race condition in pg_dump in PostgreSQL allows an object creator to execute arbitrary SQL functions as the user running pg_dump, which is often a superuser. The attack involves replacing another relation type with a view or foreign table. The attack requires waiting for pg_dump to start, but winning the race condition is trivial if the attacker retains an open transaction. Versions before PostgreSQL 16.4, 15.8, 14.13, 13.16, and 12.20 are affected. --------------------------------------------- https://www.postgresql.org/support/security/CVE-2024-7348/ ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (httpd, kernel, kernel-rt, and libtiff), Debian (postgresql-13, postgresql-15, and thunderbird), Fedora (frr, thunderbird, vim, and xrdp), Gentoo (Librsvg, Nautilus, ncurses, Percona XtraBackup, QEMU, and re2c), Red Hat (httpd, kernel, kernel-rt, openssl, and python-setuptools), SUSE (bind, ffmpeg-4, kubernetes1.23, kubernetes1.24, python-Django, and python3-Twisted), and Ubuntu (linux, linux-aws, linux-aws-5.4, linux-gcp, linux-gcp-5.4, linux-gkeop, linux-hwe-5.4, linux-ibm, linux-ibm-5.4, linux-iot, linux-kvm, linux-raspi, linux-xilinx-zynqmp, linux, linux-aws, linux-gcp, linux-gcp-5.15, linux-gke, linux-gkeop, linux-intel-iotg, linux-intel-iotg-5.15, linux-kvm, linux-lowlatency, linux-lowlatency-hwe-5.15, linux-nvidia, linux, linux-aws, linux-gcp, linux-gke, linux-ibm, linux-nvidia, linux-nvidia-6.8, linux-oem-6.8, linux-nvidia-lowlatency, linux-oracle, linux-oracle, linux-oracle-5.4, salt. --------------------------------------------- https://lwn.net/Articles/984966/ ∗∗∗ New FileSender 2.49 release with major changes ∗∗∗ --------------------------------------------- We are happy to announce the release of FileSender 2.49.

Die als "0.0.0.0 Day" bezeichnete Sicherheitslücke ermöglicht es böswilligen Websites, die Browsersicherheit zu umgehen und mit Diensten zu interagieren, die im lokalen Netzwerk einer Organisation laufen. Dies kann zu unautorisiertem Zugriff und Remotecodeausführung auf lokalen Diensten durch Angreifer außerhalb des Netzwerks führen.

===================== = End-of-Day report = ===================== Timeframe: Freitag 12-07-2024 18:00 − Montag 15-07-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Neue Absenderadresse für unsere täglichen Mails an Netzbetreiber ∗∗∗ --------------------------------------------- Wir versenden jeden Tag zwischen 150 und 250 Mails an unsere Kontakte bei Netzbetreibern in Österreich, um diese über Probleme in ihren Netzen zu informieren, die wir (bzw. unsere Datenquellen) dort gefunden haben. [..] Jetzt haben wir uns dazu entschlossen, den gleichen Weg zu nehmen, den schon viele andere Firmen beschritten haben: Wir senden ab sofort diese Mails nicht mehr von team(a)cert.at als Absender, sondern von noreply(a)cert.at aus. [..] Echte Rückfragen sollten weiterhin an team(a)cert.at gerichtet werden. --------------------------------------------- https://www.cert.at/de/blog/2024/7/neuer-absender-fuer-notifications ∗∗∗ Uncoordinated Vulnerability Disclosure: The Continuing Issues with CVD ∗∗∗ --------------------------------------------- On patch Tuesday last week, Microsoft released an update for CVE-2024-38112, which they said was being exploited in the wild. We at the Trend Micro Zero Day Initiative (ZDI) agree with them because that’s what we told them back in May when we detected this exploit in the wild and reported it to Microsoft. However, you may notice that no one from Trend or ZDI was acknowledged by Microsoft. This case has become a microcosm of the problems with coordinated vulnerability disclosure (CVD) as vendors push for coordinated disclosure from researchers but rarely practice any coordination regarding the fix. This lack of transparency from vendors often leaves researchers who practice CVD with more questions than answers. --------------------------------------------- https://www.thezdi.com/blog/2024/7/15/uncoordinated-vulnerability-disclosur… ∗∗∗ Microsoft Says Windows Not Impacted by regreSSHion as Second OpenSSH Bug Is Found ∗∗∗ --------------------------------------------- Microsoft confirmed last week that Windows is not affected by the vulnerability. --------------------------------------------- https://www.securityweek.com/microsoft-says-windows-not-impacted-by-regress… ∗∗∗ ClickFix Deception: A Social Engineering Tactic to Deploy Malware ∗∗∗ --------------------------------------------- The HTML file masquerades as a Word document, displaying an error prompt to deceive users. [..] In a nutshell, clicking on the “How to fix” button triggers the execution of JavaScript code that copies the PowerShell script directly onto the clipboard. [..] Once the script is pasted and executed in the PowerShell terminal, it allows the malware to infiltrate the victim’s system, potentially leading to data theft, system compromise, or further propagation of the malware. --------------------------------------------- https://www.mcafee.com/blogs/other-blogs/mcafee-labs/clickfix-deception-a-s… ∗∗∗ DNS hijacks target crypto platforms registered with Squarespace ∗∗∗ --------------------------------------------- A wave of coordinated DNS hijacking attacks targets decentralized finance (DeFi) cryptocurrency domains using the Squarespace registrar, redirecting visitors to phishing sites hosting wallet drainers. --------------------------------------------- https://www.bleepingcomputer.com/news/security/dns-hijacks-target-crypto-pl… ∗∗∗ June Windows Server updates break Microsoft 365 Defender features ∗∗∗ --------------------------------------------- Microsoft has confirmed that Windows Server updates from last months Patch Tuesday break some Microsoft 365 Defender features that use the network data reporting service. --------------------------------------------- https://www.bleepingcomputer.com/news/microsoft/june-windows-server-updates… ∗∗∗ Facebook ads for Windows desktop themes push info-stealing malware ∗∗∗ --------------------------------------------- Cybercriminals use Facebook business pages and advertisements to promote fake Windows themes that infect unsuspecting users with the SYS01 password-stealing malware. [..] While using Facebook advertisements to push information-stealing malware is not new, the social media platform's massive reach makes these campaigns a significant threat. --------------------------------------------- https://www.bleepingcomputer.com/news/security/facebook-ads-for-windows-the… ∗∗∗ Knot Resolver 6 News: DoS protection – operator’s overview ∗∗∗ --------------------------------------------- The team behind Knot Resolver, the scalable caching DNS resolver, is hard at work developing a complex solution for protecting DNS servers and other participants on the Internet alike against denial-of-service attacks. This effort is a part of the ongoing DNS4EU project, co-funded by the European Union1, which we are a proud part of. [..] As usual with projects from CZ.NIC, all of this code is also free and open source under the GPL license, so everyone is free to study and adapt it for their own exciting purposes. --------------------------------------------- https://en.blog.nic.cz/2024/07/15/knot-resolver-6-news-dos-protection-opera… ∗∗∗ 16-bit Hash Collisions in .xls Spreadsheets, (Sat, Jul 13th) ∗∗∗ --------------------------------------------- Since the hashing algorithm used for the protection of .xls files produces a 16-bit integer with its highest bit set, there are 32768 (0x8000) possible hash values (called verifier), and thus ample chance to generate hash collisions. I generated such a list, and included it in an update of my oledump plugin plugin_biff.py. --------------------------------------------- https://isc.sans.edu/diary/rss/31066 ∗∗∗ Protected OOXML Spreadsheets, (Mon, Jul 15th) ∗∗∗ --------------------------------------------- I was asked a question about the protection of an .xlsm spreadsheet [..] --------------------------------------------- https://isc.sans.edu/diary/rss/31070 ∗∗∗ CRYSTALRAY Hackers Infect Over 1,500 Victims Using Network Mapping Tool ∗∗∗ --------------------------------------------- A threat actor that was previously observed using an open-source network mapping tool has greatly expanded their operations to infect over 1,500 victims. Sysdig, which is tracking the cluster under the name CRYSTALRAY, said the activities have witnessed a tenfold surge, adding it includes "mass scanning, exploiting multiple vulnerabilities, and placing backdoors using multiple [open-source software] security tools." --------------------------------------------- https://thehackernews.com/2024/07/crystalray-hackers-infect-over-1500.html ∗∗∗ CVE-2024-38112: Void Banshee Targets Windows Users Through Zombie Internet Explorer in Zero-Day Attacks ∗∗∗ --------------------------------------------- Our threat hunters discovered CVE-2024-38112, which was used as a zero-day by APT group Void Banshee, to access and execute files through the disabled Internet Explorer using MSHTML. We promptly identified and reported this zero-day vulnerability to Microsoft, and it has been patched. --------------------------------------------- https://www.trendmicro.com/en_us/research/24/g/CVE-2024-38112-void-banshee.… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (cups, krb5, pgadmin4, python3.6, and yarnpkg), Mageia (freeradius, kernel, kmod-xtables-addons, kmod-virtualbox, and dwarves, kernel-linus, and squid), Red Hat (ghostscript, kernel, and less), SUSE (avahi, c-ares, cairo, cups, fdo-client, gdk-pixbuf, git, libarchive, openvswitch3, podman, polkit, python-black, python-Jinja2, python-urllib3, skopeo, squashfs, tiff, traceroute, and wget), and Ubuntu (linux, linux-azure, linux-azure-5.4, linux-bluefield, linux-gcp, linux-gcp-5.4, linux-gkeop, linux-ibm, linux-ibm-5.4, linux-kvm). --------------------------------------------- https://lwn.net/Articles/982029/ ∗∗∗ Admin-Lücke bedroht Palo Alto Networks Migration-Tool Expedition ∗∗∗ --------------------------------------------- Verschiedene Cybersicherheitsprodukte von Palo Alto Networks sind verwundbar.

Es geht hier um ernsthafte Bandbreiten und Packets/Sekunde: kein Wunder, wenn es die Angreifer geschafft haben, gute angebundene Router für ihre Zwecke einzuspannen.

The topic was the relationship between cyber security and law enforcement: how do CSIRTs and the police / public prosecutors cooperate, what works here and where are the fault lines in this collaboration. As the moderator, I wasn’t in the position to really present my own view on some of the issues, so I’m using this blogpost to document my thinking regarding the CSIRT/LE division of labour. From that starting point, this text kind of turned into a rant on what’s wrong with IT Security. --------------------------------------------- https://www.cert.at/en/blog/2024/7/csirt-le-military ∗∗∗ NIS2 - Implementing Acts ∗∗∗ --------------------------------------------- Es liegen endlich Entwürfe für die Implementing Acts zur NIS 2 Richtline vor, die Umsetzungsdetails regeln werden. Genauer gesagt: es geht um Kriterien, wann ein Vorfall meldepflichtig wird und Maßnahmen zum Risikomanagement. Seitens der EU gibt es ein öffentliches Konsultationsverfahren dazu, das bis zum 25. Juli offen ist. Die Entwürfe sind auch über diese Webseite abrufbar. --------------------------------------------- https://www.cert.at/de/blog/2024/6/nis2-implementing-acts ∗∗∗ Vorsicht vor gefälschten Gewinnspielen zur UEFA EURO 2024 ∗∗∗ --------------------------------------------- Kriminelle verbreiten per E-Mail gefälschte Gewinnspiele zur UEFA EURO 2024.

Written in Golang, Agenda supports multiple encryption modes, all controlled by its operators. The Agenda ransomware actors use double extortion tactics, demanding payment for both a decryptor and the non-release of stolen data.

Juni im Innenausschuss des Parlaments als Experte in einem Hearing zum NISG 2024 aufzutreten. Das war keine Vorladung zu einem Untersuchungsausschuss, die man kaum ausschlagen kann, sondern ein wirklich freiwilliger Termin. Ich war schon öfters beruflich im Parlament, aber bisher immer auf Einladung der Parlamentsdirektion: das hier war der erste Termin mit Mandataren. Die Illusion, mit diesem Auftritt irgendwas bewirken zu können, hatte ich nie.

[..] As for the targets, Check Point mentions successful targeting of high-profile organizations, including in government and the military sector, with most victims being from the United States, China, and Indonesia. --------------------------------------------- https://www.bleepingcomputer.com/news/security/ratel-rat-targets-outdated-a… ∗∗∗ Supply Chain Attack on WordPress.org Plugins Leads to 5 Maliciously Compromised WordPress Plugins ∗∗∗ --------------------------------------------- On Monday June 24th, 2024 the Wordfence Threat Intelligence team became aware of a plugin, Social Warfare, that was injected with malicious code on June 22, 2024 based on a forum post by the WordPress.org Plugin Review team. [..] We then reached out to the WordPress plugins team to alert them about the four additional plugins but have not yet received a response, though it appears the plugins have been delisted. [..] At this stage, we know that the injected malware attempts to create a new administrative user account and then sends those details back to the attacker-controlled server. --------------------------------------------- https://www.wordfence.com/blog/2024/06/supply-chain-attack-on-wordpress-org… ∗∗∗ Facebook PrestaShop module exploited to steal credit cards ∗∗∗ --------------------------------------------- Hackers are exploiting a flaw in a premium Facebook module for PrestaShop named pkfacebook to deploy a card skimmer on vulnerable e-commerce sites and steal peoples payment credit card details.

As we mentioned then, its initial goal was to successfully hook one of the functions related to RSA key manipulation. In this article, we will focus on the backdoor’s behavior inside OpenSSH, specifically OpenSSH portable version 9.7p1 – the most recent version at this time. --------------------------------------------- https://securelist.com/xz-backdoor-part-3-hooking-ssh/113007/ ∗∗∗ Sysinternals Process Monitor Version 4 Released, (Sat, Jun 22nd) ∗∗∗ --------------------------------------------- These releases bring improvements to performance and the user interface. --------------------------------------------- https://isc.sans.edu/diary/rss/31026 ∗∗∗ Critical RCE Vulnerability Discovered in Ollama AI Infrastructure Tool ∗∗∗ --------------------------------------------- Cybersecurity researchers have detailed a now-patch security flaw affecting the Ollama open-source artificial intelligence (AI) infrastructure platform that could be exploited to achieve remote code execution. Tracked as CVE-2024-37032, the vulnerability has been codenamed Probllama by cloud security firm Wiz. --------------------------------------------- https://thehackernews.com/2024/06/critical-rce-vulnerability-discovered.html ∗∗∗ Deye Wechselrichter: Cloud Account zeigt fremde Anlagen-/Kundendaten an ∗∗∗ --------------------------------------------- In deutschen Objekten dürften einige Balkonkraftwerke und auch fest installierte Solaranlagen arbeiten, bei denen Wechselrichter des chinesischen Herstellers Deye verwendet werden. [..] Ein Leser hat mich bereits im Mai 2024 mit einem anderen Problem konfrontiert. Er konnte die Anlagendaten einer ihm komplett unbekannten Person einsehen. [..] Der Leser hat die deutsche Dependance kontaktiert [..] Die Reaktion hat den Leser erstaunt, denn als er den Hersteller auf den Bug hinwies, habe dieser das bezweifelt. [..] Generöser Weise bot Deye dem Betroffenen an, zu helfen, die zweite Anlage aus dem Benutzerkonto auszutragen. --------------------------------------------- https://www.borncity.com/blog/2024/06/24/deye-wechselrichter-cloud-account-… ∗∗∗ Horror auf dem Vision Pro: Exploit schleust Spinnen und Fledermäuse in den Raum ∗∗∗ --------------------------------------------- Damit der Angriff gelingt, muss der Vision-Pro-Nutzer lediglich eine präparierte Webseite aufrufen.

Due to hardcoded credentials and an unfitting application architecture an attacker could decrypt the configuration file and retrieve the password which is used to configure the software. Thus, an attacker could completely disable the software. [..] The vendor provides a patched version 8.30.xx.903 since May 2024 [..] Since the hardcoded password for the encryption is not fixed, we ask if this will be addressed as well. Vendor responds that this will be addressed in a future release. --------------------------------------------- https://sec-consult.com/vulnerability-lab/advisory/multiple-vulnerabilities… ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (ipa and libreswan), Debian (netty), Fedora (python-PyMySQL, tomcat, and webkitgtk), Gentoo (Flatpak, GLib, JHead, LZ4, and RDoc), Mageia (thunderbird), Oracle (nghttp2 and thunderbird), Red Hat (dnsmasq, libreswan, pki-core, and python3.11), Slackware (emacs), SUSE (gnome-settings-daemon, libarchive, qpdf, vte, and wget), and Ubuntu (libhibernate3-java). --------------------------------------------- https://lwn.net/Articles/979520/ ∗∗∗ CosmicSting: Schwachstelle CVE-2024-34102 gefährdet Adobe Commerce- und Magento-Shops ∗∗∗ --------------------------------------------- Seit Mitte des Monats ist bekannt, dass in Adobe Commerce- und Magento-Online-Shops die Schwachstelle CVE-2024-34102 existiert.

However, its use of Discord and emojis as a command and control (C2) platform makes the malware stand out from others and could allow it to bypass security software that looks for text-based commands. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-linux-malware-is-control… ∗∗∗ New ARM TIKTAG attack impacts Google Chrome, Linux systems ∗∗∗ --------------------------------------------- A new speculative execution attack named "TIKTAG" targets ARMs Memory Tagging Extension (MTE) to leak data with over a 95% chance of success, allowing hackers to bypass the security feature. [..] Leaking those tags does not directly expose sensitive data such as passwords, encryption keys, or personal information.

===================== = End-of-Day report = ===================== Timeframe: Mittwoch 15-05-2024 18:00 − Donnerstag 16-05-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: Thomas Pribitzer ===================== = News = ===================== ∗∗∗ To the Moon and back(doors): Lunar landing in diplomatic missions ∗∗∗ --------------------------------------------- ESET researchers provide technical analysis of the Lunar toolset, likely used by the Turla APT group, that infiltrated a European ministry of foreign affairs. --------------------------------------------- https://www.welivesecurity.com/en/eset-research/moon-backdoors-lunar-landin… ∗∗∗ Windows Quick Assist abused in Black Basta ransomware attacks ∗∗∗ --------------------------------------------- Microsoft has been investigating this campaign since at least mid-April 2024, and, as they observed, the threat group (tracked as Storm-1811) started their attacks by email bombing the target after subscribing their addresses to various email subscription services. Once their mailboxes flood with unsolicited messages, the threat actors call them while impersonating a Microsoft technical support or the attacked company's IT or help desk staff to help remediate the spam issues. --------------------------------------------- https://www.bleepingcomputer.com/news/security/windows-quick-assist-abused-… ∗∗∗ Google patches third exploited Chrome zero-day in a week ∗∗∗ --------------------------------------------- Google has released a new emergency Chrome security update to address the third zero-day vulnerability exploited in attacks within a week. --------------------------------------------- https://www.bleepingcomputer.com/news/google/google-patches-third-exploited… ∗∗∗ Springtail: New Linux Backdoor Added to Toolkit ∗∗∗ --------------------------------------------- The backdoor (Linux.Gomir) appears to be a Linux version of the GoBear backdoor, which was used in a recent Springtail campaign that saw the attackers deliver malware via Trojanized software installation packages. Gomir is structurally almost identical to GoBear, with extensive sharing of code between malware variants. --------------------------------------------- https://symantec-enterprise-blogs.security.com/threat-intelligence/springta… ∗∗∗ Detecting Compromise of CVE-2024-3400 on Palo Alto Networks GlobalProtect Devices ∗∗∗ --------------------------------------------- This blog post aims to provide details on methods for investigating potentially compromised Palo Alto Networks firewall devices and a general approach towards edge device threat detection. --------------------------------------------- https://www.volexity.com/blog/2024/05/15/detecting-compromise-of-cve-2024-3… ∗∗∗ ViperSoftX Uses Deep Learning-based Tesseract to Exfiltrate Information ∗∗∗ --------------------------------------------- AhnLab SEcurity intelligence Center (ASEC) has recently discovered ViperSoftX attackers using Tesseract to exfiltrate users’ image files. ViperSoftX is a malware strain responsible for residing on infected systems and executing the attackers’ commands or stealing cryptocurrency-related information. The malware newly discovered this time utilizes the open-source OCR engine Tesseract. --------------------------------------------- https://asec.ahnlab.com/en/65426/ ∗∗∗ Talos releases new macOS open-source fuzzer ∗∗∗ --------------------------------------------- Cisco Talos has developed a fuzzer that enables us to test macOS software on commodity hardware. [..] Compared to fuzzing for software vulnerabilities on Linux, where most of the code is open-source, targeting anything on macOS presents a few difficulties. --------------------------------------------- https://blog.talosintelligence.com/talos-releases-new-macos-fuzzer/ ∗∗∗ Llama Drama: Critical Vulnerability CVE-2024-34359 Threatening Your Software Supply Chain ∗∗∗ --------------------------------------------- Jinja2: This library is a popular Python tool for template rendering, primarily used for generating HTML. Its ability to execute dynamic content makes it powerful but can pose a significant security risk if not correctly configured to restrict unsafe operations. `llama_cpp_python`: This package integrates Python's ease of use with C++'s performance, making it ideal for complex AI models handling large data volumes. However, its use of Jinja2 for processing model metadata without enabling necessary security safeguards exposes it to template injection attacks. [..] The vulnerability identified has been addressed in version 0.2.72 of the llama-cpp-python package, which includes a fix enhancing sandboxing and input validation measures. --------------------------------------------- https://checkmarx.com/blog/llama-drama-critical-vulnerability-cve-2024-3435… ∗∗∗ The xz apocalypse that almost was* ∗∗∗ --------------------------------------------- Given Bitsight’s pretty broad view of the Internet, I thought I could contribute to the discussion a bit and ask “how bad could this have been?” and as a corollary “how many chances would there have been to notice?” So let’s get into the “how bad could this have been?” question first. --------------------------------------------- https://www.bitsight.com/blog/xz-apocalypse-almost-was ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Thursday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (.NET 7.0, .NET 8.0, and nodejs:20), Debian (chromium, firefox-esr, ghostscript, and libreoffice), Fedora (djvulibre, mingw-glib2, mingw-python-jinja2, and mingw-python-werkzeug), Oracle (.NET 7.0, .NET 8.0, kernel, and nodejs:18), Red Hat (nodejs:20), Slackware (gdk and git), SUSE (python), and Ubuntu (linux-hwe-5.15, linux-raspi). --------------------------------------------- https://lwn.net/Articles/973908/ ∗∗∗ Sicherheitslücken in Überwachungskameras und Video-Babyphones ∗∗∗ --------------------------------------------- Schwachstellen aus der ThroughTek Kaylay-IoT-Plattform. Dringend Update-Status der IoT-Geräte prüfen. --------------------------------------------- https://www.zdnet.de/88415973/sicherheitsluecken-in-ueberwachungskameras-un… ∗∗∗ WLAN-Attacke: SSID-Verwechslungs-Angriff macht Nutzer verwundbar ∗∗∗ --------------------------------------------- Eine Sicherheitslücke in WLAN-Protokollen führt dazu, dass Angreifer in einer Man-in-the-Middle-Position WLAN-Verkehr manipulieren können. [..] Das ohnehin nicht mehr sicher zu nutzende WEP ist anfällig, und das neuere, sonst sicherere WPA3 ebenfalls. 802.11X/EAP und Mesh-Netzwerke mit AMPE-Authentifizierung sind laut Auflistung ebenfalls für SSID-Confusion verwundbar. --------------------------------------------- https://heise.de/-9720818 ∗∗∗ Cisco: Updates schließen Sicherheitslücken in mehreren Produkten ∗∗∗ --------------------------------------------- In mehreren Cisco-Produkten klaffen Sicherheitslücken, durch die Angreifer sich etwa root-Rechte verschaffen und Geräte kompromittieren können.
