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.

Es geht hier um ernsthafte Bandbreiten und Packets/Sekunde: kein Wunder, wenn es die Angreifer geschafft haben, gute angebundene Router für ihre Zwecke einzuspannen. [..] Ich habe das als Anlass genommen, mal in unserer Datenbasis (basierend auf Scans von Shadowserver) nachzuschauen, wie es um diese Geräte in Österreich bestellt ist: MikroTik Router, die per SNMP ihre Modellnummern verraten. --------------------------------------------- https://www.cert.at/de/aktuelles/2024/7/mikrotik-snmp ∗∗∗ Authy: Hacker greifen Millionen von Telefonnummern über eine ungesicherte API ab ∗∗∗ --------------------------------------------- Nachdem Kriminelle eine CSV-Datei mit Telefonnummern von angeblich 33 Millionen Authy-Nutzern geleakt haben, drohen unter anderem SMS-Phishing-Attacken. --------------------------------------------- https://heise.de/-9789229 ∗∗∗ Backup-Fiasko in Indonesien: Hacker verschenken Schlüssel und entschuldigen sich ∗∗∗ --------------------------------------------- Ein Ransomwareangriff bereitet Indonesien enorme Probleme.

[..] Recently, the remote code execution vulnerability CVE-2024-23692 in the HFS program that provides web services was announced. Attack cases against vulnerable versions of HFS continue to be detected ever since. Because HFS is exposed to the public in order to enable users to connect to the HFS web server and download files, it can be a target for external attacks if it has a vulnerability. --------------------------------------------- https://asec.ahnlab.com/en/67650/ ∗∗∗ WordPress User Enumeration: Risks & Mitigation Steps ∗∗∗ --------------------------------------------- In this post, we’re diving deep into WordPress user enumeration.

But among certain old-school Russian hackers it is not uncommon to find major players who have done little to prevent people from figuring out who they are in real life. A case study in this phenomenon is "x999xx," the nickname chosen by a venerated Russian hacker who specializes in providing the initial network access to various ransomware groups. --------------------------------------------- https://krebsonsecurity.com/2024/07/the-not-so-secret-network-access-broker… ∗∗∗ Dissecting GootLoader With Node.js ∗∗∗ --------------------------------------------- We demonstrate effective methods to circumvent anti-analysis evasion techniques from GootLoader, a backdoor and loader malware distributed through fake forum posts. --------------------------------------------- https://unit42.paloaltonetworks.com/javascript-malware-gootloader/ ∗∗∗ No room for error: Don’t get stung by these common Booking.com scams ∗∗∗ --------------------------------------------- >From sending phishing emails to posting fake listings, here’s how fraudsters hunt for victims while you’re booking your well-earned vacation. --------------------------------------------- https://www.welivesecurity.com/en/scams/common-bookingcom-scams/ ∗∗∗ Senate leader demands answers from CISA on Ivanti-enabled hack of sensitive systems ∗∗∗ --------------------------------------------- Sen. Charles Grassley (R-IA) on Wednesday sent Cybersecurity and Infrastructure Security Agency (CISA) Director Jen Easterly a stern letter seeking documentation and answers relating to a January hack of the agency’s Chemical Security Assessment Tool (CSAT) along with the breach of a second sensitive system.

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.

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.

Even if it is used to block users from malicious sites, it needs to be properly declared to the user, and switches to turn it off will have to function. This could be a particular problem if queries to other DNS filtering services are intercepted.

[..] Synology NAS run a Linux distribution called DSM. This operating system has plenty of third-party tools but lacks pure forensics tools.

The techniques have been collectively dubbed Pathfinder by a group of academics from the University of California San Diego, Purdue University, UNC Chapel Hill, Georgia Institute of Technology, and Google. [..] Following responsible disclosure in November 2023, Intel, in an advisory released last month, said Pathfinder builds on Spectre v1 attacks and that previously deployed mitigations for Spectre v1 and traditional side-channels mitigate the reported exploits. There is no evidence that it impacts AMD CPUs. --------------------------------------------- https://thehackernews.com/2024/05/new-spectre-style-pathfinder-attack.html ∗∗∗ Ghidra nanoMIPS ISA module ∗∗∗ --------------------------------------------- Here we will demonstrate how to load a MediaTek baseband firmware into Ghidra for analysis with our nanoMIPS ISA module. --------------------------------------------- https://research.nccgroup.com/2024/05/07/ghidra-nanomips-isa-module/ ∗∗∗ Vorsicht vor gefälschten Online-Banking-Seiten auf Bing, Google & Co ∗∗∗ --------------------------------------------- Kriminelle schalten Anzeigen in Suchmaschinen (vor allem BING) und locken so Opfer auf gefälschte Online-Banking-Seiten.

I’ve tried to keep as quiet as possible about this one for various reasons (and I was not involved in the CSRB report, even anonymously) — although long time followers will know I’ve been often critical of Microsoft’s security posture. The CSRB report is well worth a read — they did a great job. [..] As always, the proof is in the pudding, not the vendor blog.

===================== = End-of-Day report = ===================== Timeframe: Donnerstag 02-05-2024 18:00 − Freitag 03-05-2024 18:00 Handler: Alexander Riepl Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Microsoft rolls out passkey auth for personal Microsoft accounts ∗∗∗ --------------------------------------------- Microsoft announced that Windows users can now log into their Microsoft consumer accounts using a passkey, allowing users to authenticate using password-less methods such as Windows Hello, FIDO2 security keys, biometric data (facial scans or fingerprints), or device PINs. [..] Microsoft had already added passkey support to Windows for logging into websites and applications, but with the additional support for Microsoft accounts, consumers can now easily log in without entering a password. --------------------------------------------- https://www.bleepingcomputer.com/news/microsoft/microsoft-rolls-out-passkey… ∗∗∗ Scans Probing for LB-Link and Vinga WR-AC1200 routers CVE-2023-24796, (Thu, May 2nd) ∗∗∗ --------------------------------------------- Before diving into the vulnerability, a bit about the affected devices. LB-Link, the make of the devices affected by this vulnerability, produces various wireless equipment that is sometimes sold under different brands and labels. This will make it difficult to identify affected devices. These devices are often low-cost "no name" solutions or, in some cases, may even be embedded, which makes it even more difficult to find firmware updates. [..] And yes, the vulnerability evolves around the "user=admin" cookie and a command injection in the password parameter. This is too stupid to waste any more time on, but it is common enough to just give up and call it a day. --------------------------------------------- https://isc.sans.edu/diary/rss/30890 ∗∗∗ Mal.Metrica Redirects Users to Scam Sites ∗∗∗ --------------------------------------------- One of our analysts recently identified a new Mal.Metrica redirect scam on compromised websites, but one that requires a little bit of effort on the part of the victim. It’s another lesson for web users to be careful what they click on, and to be wary of anything suspicious that pops up in their browser — even if it’s coming from a website that they would otherwise trust. --------------------------------------------- https://blog.sucuri.net/2024/05/mal-metrica-redirects-users-to-scam-sites.h… ∗∗∗ Hackers Increasingly Abusing Microsoft Graph API for Stealthy Malware Communications ∗∗∗ --------------------------------------------- Since January 2022, multiple nation-state-aligned hacking groups have been observed using Microsoft Graph API for C&C. This includes threat actors tracked as APT28, REF2924, Red Stinger, Flea, APT29, and OilRig. --------------------------------------------- https://thehackernews.com/2024/05/hackers-increasingly-abusing-microsoft.ht… ∗∗∗ Europol op shutters 12 scam call centers and cuffs 21 suspected fraudsters ∗∗∗ --------------------------------------------- A Europol-led operation dubbed “Pandora” has shut down a dozen phone scam centers, and arrested 21 suspects. [..] Beginning in December 2023, German investigators deployed more than 100 officers to trace the scam calls back to the source - call centers run by crooks - and then monitored them. That effort resulted in the interception of more than 1.3 million "nefarious conversations." Baden-Württemberg State Criminal Police officers had to set up a call center of their own so that they could contact potential victims, warning more than 80 percent of them. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2024/05/03/operation_pa… ∗∗∗ These Dangerous Scammers Don’t Even Bother to Hide Their Crimes ∗∗∗ --------------------------------------------- “Yahoo Boy” cybercriminals are openly running dozens of scams across Facebook, WhatsApp, Telegram, TikTok, YouTube, and more. [..] While the Yahoo Boys have been active for years, all the experts spoken to for this piece say they should be treated more seriously by social media companies and law enforcement. --------------------------------------------- https://www.wired.com/story/yahoo-boys-scammers-facebook-telegram-tiktok-yo… ∗∗∗ Adding insult to injury: crypto recovery scams ∗∗∗ --------------------------------------------- Once your crypto has been stolen, it is extremely difficult to get back – be wary of fake promises to retrieve your funds and learn how to avoid becoming a victim twice over. --------------------------------------------- https://www.welivesecurity.com/en/scams/crypto-recovery-scams-insult-injury/ ∗∗∗ CVE-2024-2887: A Pwn2Own Winning Bug in Google Chrome ∗∗∗ --------------------------------------------- In this guest blog from Master of Pwn winner Manfred Paul, he details CVE-2024-2887 – a type confusion bug that occurs in both Google Chrome and Microsoft Edge (Chromium). He used this bug as a part of his winning exploit that led to code execution in the renderer of both browsers. This bug was quickly patched by both Google and Microsoft. Manfred has graciously provided this detailed write-up of the vulnerability and how he exploited it at the contest. --------------------------------------------- https://www.thezdi.com/blog/2024/5/2/cve-2024-2887-a-pwn2own-winning-bug-in… ∗∗∗ CISA and FBI Release Secure by Design Alert to Urge Manufacturers to Eliminate Directory Traversal Vulnerabilities ∗∗∗ --------------------------------------------- This Alert was crafted in response to recent well-publicized threat actor campaigns that exploited directory traversal vulnerabilities in software (e.g., CVE-2024-1708, CVE-2024-20345) to compromise users of the software—impacting critical infrastructure sectors, including the Healthcare and Public Health Sector. --------------------------------------------- https://www.cisa.gov/news-events/alerts/2024/05/02/cisa-and-fbi-release-sec… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Fedora (chromium, grub2, httpd, kernel, libcoap, matrix-synapse, python-pip, and rust-pythonize), Red Hat (kernel and libxml2), SUSE (kernel), and Ubuntu (eglibc, glibc and php7.4, php8.1, php8.2). --------------------------------------------- https://lwn.net/Articles/972351/ ∗∗∗ IBM Security Bulletins ∗∗∗ --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

===================== = End-of-Day report = ===================== Timeframe: Dienstag 30-04-2024 18:00 − Donnerstag 02-05-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: n/a ===================== = News = ===================== ∗∗∗ CVD - Notizen zur Pressekonferenz ∗∗∗ --------------------------------------------- Ich wurde eingeladen, heute bei einer Pressekonferenz von Epicenter.works am Podium zu sitzen. Es ging um einen Fall, bei dem es im Zuge einer klassischen verantwortungsvollen Offenlegung einer Schwachstelle (Responsible Disclosure, bzw Coordinated Vulnerability Disclosure [CVD]) zu einer Anzeige gekommen ist. Nachzulesen ist der Fall auf der Epicenter Webseite. Ich will hier kurz meine Notizen / Speaking Notes zusammenfassen. --------------------------------------------- https://cert.at/de/blog/2024/4/cvd-policy ∗∗∗ CISA warnt: MS Smartscreen- und Gitlab-Sicherheitslücke werden angegriffen ∗∗∗ --------------------------------------------- Die US-Cybersicherheitsbehörde CISA hat Angriffe auf eine Lücke im Microsoft Smartscreen und auf eine Gitlab-Schwachstelle gesichtet. --------------------------------------------- https://heise.de/-9705715 ∗∗∗ Digitale Signatur: Datenleak bei Dropbox Sign ∗∗∗ --------------------------------------------- Unbekannte Angreifer konnten auf Kundendaten des digitalen Signaturservices Dropbox Sign zugreifen. Andere Dropbox-Produkte sollen nicht betroffen sein. --------------------------------------------- https://heise.de/-9705355 ∗∗∗ Windows 10/11/Server 2022: Kein Fix für den Installationsfehler 0x80070643 beim WinRE-Update mehr ∗∗∗ --------------------------------------------- Seit Januar 2024 kämpfen Nutzer von Windows 10 und Windows 11 (sowie Windows Server 2022) mit dem Versuch Microsofts, ein Update der WinRE-Umgebung zu installieren. Im Januar 2024 ließen zahlreiche Nutzer im Umfeld des Patchday beim Versuch, das Update KB5034441 zu installieren, in den Installationsfehler 0x80070643. Trotz mehrerer Versuche zur Nachbesserung in den Folgemonaten ist es Microsoft nicht gelungen, den Installationsfehler zu beseitigen. Nun kommt das Eingeständnis, dass es keinen automatischen Fix für das Update gibt – es ist Handarbeit angesagt. --------------------------------------------- https://www.borncity.com/blog/2024/05/02/windows-10-11-kein-fix-fr-den-inst… ∗∗∗ “Dirty stream” attack: Discovering and mitigating a common vulnerability pattern in Android apps ∗∗∗ --------------------------------------------- Microsoft discovered a vulnerability pattern in multiple popular Android applications that could enable a malicious application to overwrite files in the vulnerable application’s internal data storage directory, which could lead to arbitrary code execution and token theft, among other impacts. We have shared our findings with Google’s Android Application Security Research team, as well as the developers of apps found vulnerable to this issue. --------------------------------------------- https://www.microsoft.com/en-us/security/blog/2024/05/01/dirty-stream-attac… ∗∗∗ Another Day, Another NAS: Attacks against Zyxel NAS326 devices CVE-2023-4473, CVE-2023-4474, (Tue, Apr 30th) ∗∗∗ --------------------------------------------- Yesterday, I talked about attacks against a relatively recent D-Link NAS vulnerability. Today, scanning my honeypot logs, I found an odd URL that I didn't recognize. The vulnerability is a bit older but turns out to be targeting yet another NAS. [..] Based on our logs, only one IP address exploits the vulnerability: %%ip: 89.190.156.248%%. --------------------------------------------- https://isc.sans.edu/diary/rss/30884 ∗∗∗ Android Malware Wpeeper Uses Compromised WordPress Sites to Hide C2 Servers ∗∗∗ --------------------------------------------- Cybersecurity researchers have discovered a previously undocumented malware targeting Android devices that uses compromised WordPress sites as relays for its actual command-and-control (C2) servers for detection evasion. The malware, codenamed Wpeeper, is an ELF binary that leverages the HTTPS protocol to secure its C2 communications. [..] The ELF binary is embedded within a repackaged application that purports to be the UPtodown App Store app for Android (package name "com.uptodown"), with the APK file acting as a delivery vehicle for the backdoor in a manner that evades detection. --------------------------------------------- https://thehackernews.com/2024/05/android-malware-wpeeper-uses.html ∗∗∗ New Cuttlefish Malware Hijacks Router Connections, Sniffs for Cloud Credentials ∗∗∗ --------------------------------------------- A new malware called Cuttlefish is targeting small office and home office (SOHO) routers with the goal of stealthily monitoring all traffic through the devices and gather authentication data from HTTP GET and POST requests. [..] Cuttlefish has been active since at least July 27, 2023, with the latest campaign running from October 2023 through April 2024 and predominantly infecting 600 unique IP addresses associated with two Turkish telecom providers. --------------------------------------------- https://thehackernews.com/2024/05/new-cuttlefish-malware-hijacks-router.html ∗∗∗ Autodesk: Important Security Update for Autodesk Drive ∗∗∗ --------------------------------------------- In March, Autodesk was made aware of an incident where an external user published documents to Autodesk Drive containing links to a phishing web site. Our Cyber Threat Management & Response Team immediately responded to this incident, and the malicious files are no longer being hosted on Autodesk Drive. No customers have reported being impacted by this incident. --------------------------------------------- https://www.autodesk.com/trust/security-advisories/adsk-sa-2024-autodesk-dr… ∗∗∗ Analysis of TargetCompany’s Attacks Against MS-SQL Servers (Mallox, BlueSky Ransomware) ∗∗∗ --------------------------------------------- While monitoring attacks targeting MS-SQL servers, AhnLab SEcurity intelligence Center (ASEC) recently identified cases of the TargetCompany ransomware group installing the Mallox ransomware. The TargetCompany ransomware group primarily targets improperly managed MS-SQL servers to install the Mallox ransomware. While these attacks have been ongoing for several years, here we will outline the correlation between the newly identified malware and previous attack cases involving the distribution of the Tor2Mine CoinMiner and BlueSky ransomware. --------------------------------------------- https://asec.ahnlab.com/en/64921/ ∗∗∗ CISA and Partners Release Fact Sheet on Defending OT Operations Against Ongoing Pro-Russia Hacktivist Activity ∗∗∗ --------------------------------------------- This fact sheet provides information and mitigations associated with cyber operations conducted by pro-Russia hacktivists who seek to compromise industrial control systems (ICS) and small-scale operational technology (OT) systems in North American and European critical infrastructure sectors, including Water and Wastewater Systems, Dams, Energy, and Food and Agriculture Sectors. --------------------------------------------- https://www.cisa.gov/news-events/alerts/2024/05/01/cisa-and-partners-releas… ===================== = Vulnerabilities = ===================== ∗∗∗ Kritische Sicherheitslücken in ArubaOS - Updates verfügbar ∗∗∗ --------------------------------------------- In ArubaOS, dem Betriebssystem vieler Geräte von HPE Aruba Networks, existieren mehrere kritische Sicherheitslücken.

This lays the ground for requesting to take the conversation outside the platform onto a supposedly safer communications tool. At this stage, the fraudster sends a link to the victim that will take them to a seemingly legitimate verification platform where the victim will have to verify they're not a sexual offender. --------------------------------------------- https://www.bleepingcomputer.com/news/security/fbi-warns-of-fake-verificati… ∗∗∗ Millions of Malicious Imageless Containers Planted on Docker Hub Over 5 Years ∗∗∗ --------------------------------------------- Cybersecurity researchers have discovered multiple campaigns targeting Docker Hub by planting millions of malicious "imageless" containers over the past five years, once again underscoring how open-source registries could pave the way for supply chain attacks.

Diesmal nicht mit dem Blickwinkel „macht das Sinn“, sondern mit Fokus auf die Formulierungen. Das erinnert mich ein bisschen an die Zeit, als ich bei der Erstellung von RFCs mitgearbeitet habe und da auch bei Reviews jedes Wort genau auf mögliche Fehldeutungen abgeklopft habe. Ich hatte beim Lesen drei Dokumente offen: den Gesetzesentwurf, die Richtlinie in der deutschen Version und auch die englische Fassung. Und viele der schlechten Formulierungen waren keine Erfindungen aus Wien, sondern wurden schon in Brüssel erfunden. Ich will das hier dokumentieren. --------------------------------------------- https://cert.at/de/blog/2024/4/nis2-formulierungen ∗∗∗ Researchers sinkhole PlugX malware server with 2.5 million unique IPs ∗∗∗ --------------------------------------------- Researchers have sinkholed a command and control server for a variant of the PlugX malware and observed in six months more than 2.5 million connections from unique IP addresses.

Ohne TLS können Tastatureingaben jedoch von Dritten mitgeschnitten werden.

[..] For those unfamiliar with defensive security products, QRadar is the mastermind application that can sit on-premise or in the cloud via IBM's SaaS offering. Quite simply, it's IBM's Security Information and Event Management (SIEM) product - and is the heart of many enterprise's security software stack. --------------------------------------------- https://labs.watchtowr.com/ibm-qradar-when-the-attacker-controls-your-secur… ∗∗∗ Krypto-Scams: Coinbase warnt EU-Kunden vor iPhone-Sideloading ∗∗∗ --------------------------------------------- Die Kryptobörse weist europäische Kunden an, die App nur aus Apples App Store zu beziehen.

Some apps can also display the distance of the user to other users. This feature is quite useful for coordinating meetups, indicating whether a potential match is just a short distance away or a kilometer apart. However, openly sharing your distance with other users can create serious security issues. The risks become apparent when you consider the potential misuse by a curious individual armed with advanced knowledge of techniques like trilateration. --------------------------------------------- https://research.checkpoint.com/2024/the-illusion-of-privacy-geolocation-ri… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (cockpit), Mageia (python-pygments), Red Hat (nodejs), Slackware (httpd and nghttp2), SUSE (avahi, gradle, gradle-bootstrap, and squid), and Ubuntu (xorg-server, xwayland). --------------------------------------------- https://lwn.net/Articles/968561/ ∗∗∗ Lexmark: Hochriskante Lücken erlauben Codeschmuggel auf Drucker ∗∗∗ --------------------------------------------- Lexmark warnt vor Sicherheitslücken in diversen Drucker-Firmwares.

[..] The Jia Tan persona has vanished since the backdoor was discovered [..] In fact, the only real footprints Jia Tan appears to have left behind were their contributions to the open source development community, where they were a prolific contributor: Disturbingly, Jia Tan’s first code change was to the “libarchive” compression library, another very widely used open source component. [..] In total, Jia Tan made 6,000 code changes to at least seven projects between 2021 and February 2024 [..] Security researchers agree, at least, that it’s unlikely that Jia Tan is a real person, or even one person working alone. Instead, it seems clear that the persona was the online embodiment of a new tactic from a new, well-organized organization—a tactic that nearly worked. --------------------------------------------- https://www.wired.com/story/jia-tan-xz-backdoor/ ∗∗∗ XZ Utils Backdoor Attack Brings Another Similar Incident to Light ∗∗∗ --------------------------------------------- In a post on Mastodon, Hans-Christoph Steiner, a maintainer of F-Droid, recalled a similar story from 2020, when an individual attempted to get F-Droid developers to add what later was determined to be a SQL injection vulnerability.

Alternativ hätte dieser Blogpost auch einen deutlich knackigeren Titel haben können - "CVE-2024-3094", um jene geht es in diesem Beitrag nämlich. --------------------------------------------- https://cert.at/de/blog/2024/4/staatlich-gesponserte-entwicklung-quelloffen… ∗∗∗ The amazingly scary xz sshd backdoor, (Mon, Apr 1st) ∗∗∗ --------------------------------------------- The whole story around this is both fascinating and scary – and I’m sure will be told around numerous time, so in this diary I will put some technical things about the backdoor that I reversed for quite some time (and I have a feeling I could spend 2 more weeks on this). [..] Let’s take a look at couple of fascinating things in this backdoor. --------------------------------------------- https://isc.sans.edu/diary/rss/30802 ∗∗∗ On Cybersecurity Alert Levels ∗∗∗ --------------------------------------------- Last week I was invited to provide input to a tabletop exercise for city-level crisis managers on cyber security risks and the role of CSIRTs. The organizers brought a color-coded threat-level sheet (based on the CISA Alert Levels) to the discussion and asked whether we also do color-coded alerts in Austria and what I think of these systems. My answer was negative on both questions, and I think it might be useful if I explain my rationale here. --------------------------------------------- https://cert.at/en/blog/2024/4/on-cybersecurity-alert-levels ∗∗∗ Heartbleed is 10 Years Old – Farewell Heartbleed, Hello QuantumBleed! ∗∗∗ --------------------------------------------- Heartbleed made most certificates vulnerable. The future problem is that quantum decryption will make all certificates and everything else using RSA encryption vulnerable to everyone. --------------------------------------------- https://www.securityweek.com/heartbleed-is-10-years-old-farewell-heartbleed… ∗∗∗ From OneNote to RansomNote: An Ice Cold Intrusion ∗∗∗ --------------------------------------------- In late February 2023, threat actors rode a wave of initial access using Microsoft OneNote files. In this case, we observed a threat actor deliver IcedID using this method. After loading IcedID and establishing persistence, there were no further actions, other than beaconing for over 30 days. The threat actor used Cobalt Strike and AnyDesk to target a file server and a backup server. The threat actor used FileZilla to exfiltrate data from the network before deploying Nokoyawa ransomware. --------------------------------------------- https://thedfirreport.com/2024/04/01/from-onenote-to-ransomnote-an-ice-cold… ∗∗∗ Adversaries are leveraging remote access tools now more than ever — here’s how to stop them ∗∗∗ --------------------------------------------- While there are many legitimate uses for this software, adversaries are also finding ways to use them for command and control in their campaigns. --------------------------------------------- https://blog.talosintelligence.com/adversaries-are-leveraging-remote-access… ∗∗∗ Earth Freybug Uses UNAPIMON for Unhooking Critical APIs ∗∗∗ --------------------------------------------- This article provides an in-depth look into two techniques used by Earth Freybug actors: dynamic-link library (DLL) hijacking and application programming interface (API) unhooking to prevent child processes from being monitored via a new malware we’ve discovered and dubbed UNAPIMON. --------------------------------------------- https://www.trendmicro.com/en_us/research/24/d/earth-freybug.html ===================== = Vulnerabilities = ===================== ∗∗∗ Update #1: Kritische Sicherheitslücke/Hintertüre in xz-utils (CVE-2024-3094) ∗∗∗ --------------------------------------------- In den Versionen 5.6.0 und 5.6.1 der weit verbreiteten Bibliothek xz-utils wurde eine Hintertür entdeckt. xz-utils wird häufig zur Komprimierung von Softwarepaketen, Kernel-Images und initramfs-Images verwendet. Die Lücke ermöglicht es nicht authentifizierten Angreifer:innen, die sshd-Authentifizierung auf verwundbaren Systemen zu umgehen und unauthorisierten Zugriff auf das gesamte System zu erlangen.

[..] In 2024, Tycoon 2FA released a new version that is stealthier, indicating a continuous effort to improve the kit. Currently, the service leverages 1,100 domains and has been observed in thousands of phishing attacks. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-mfa-bypassing-phishing-k… ∗∗∗ Hackers Hijack GitHub Accounts in Supply Chain Attack Affecting Top-gg and Others ∗∗∗ --------------------------------------------- Unidentified adversaries orchestrated a sophisticated attack campaign that has impacted several individual developers as well as the GitHub organization account associated with Top.gg, a Discord bot discovery site. [..] The software supply chain attack is said to have led to the theft of sensitive information, including passwords, credentials, and other valuable data. --------------------------------------------- https://thehackernews.com/2024/03/hackers-hijack-github-accounts-in.html ∗∗∗ New Go loader pushes Rhadamanthys stealer ∗∗∗ --------------------------------------------- A malicious ad for the popular admin tool PuTTY leads victims to a fake site that downloads malware. --------------------------------------------- https://www.malwarebytes.com/blog/threat-intelligence/2024/03/new-go-loader… ∗∗∗ Phishing mit gefälschten Rechnungen von Anwaltskanzleien ∗∗∗ --------------------------------------------- Laut BlueVoyant geben sich die Angreifer als Anwaltskanzleien aus und missbrauchen das Vertrauen, das ihre Opfer "seriösen" Juristen entgegenbringen. [..] Die NaurLegal-Kampagne täuscht Legitimität vor, indem sie PDF-Dateien mit seriös anmutenden Dateinamen wie „Rechnung_[Nummer]_von_[Name der Anwaltskanzlei].pdf“ erstellt und versendet. [..] Die Infrastruktur der NaurLegal-Kampagne umfasst Domänen, die mit WikiLoader verknüpft sind und deren Folgeaktivitäten auf eine Zuordnung zu dieser Malware-Familie schließen lassen. WikiLoader ist bekannt für ausgefeilte Verschleierungstechniken, wie z. B. die Überprüfung von Wikipedia-Antworten auf bestimmte Zeichenfolgen, um Sandbox-Umgebungen zu umgehen. --------------------------------------------- https://www.zdnet.de/88414996/phishing-mit-gefaelschten-rechnungen-von-anwa… ∗∗∗ CISA and FBI Release Secure by Design Alert to Urge Manufacturers to Eliminate SQL Injection Vulnerabilities ∗∗∗ --------------------------------------------- Today, CISA and the Federal Bureau of Investigation (FBI) released a joint Secure by Design Alert, Eliminating SQL Injection Vulnerabilities in Software.

This is the first time we have seen this APT29 cluster target political parties, indicating a possible area of emerging operational focus beyond the typical targeting of diplomatic missions. Based on the SVR’s responsibility to collect political intelligence and this APT29 cluster’s historical targeting patterns, we judge this activity to present a broad threat to European and other Western political parties from across the political spectrum. --------------------------------------------- https://www.mandiant.com/resources/blog/apt29-wineloader-german-political-p… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Monday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (cacti, firefox-esr, freeipa, gross, libnet-cidr-lite-perl, python2.7, python3.7, samba, and thunderbird), Fedora (amavis, chromium, clojure, firefox, gnutls, kubernetes, and tcpreplay), Mageia (freeimage, libreswan, nodejs-hawk, and python, python3), Oracle (golang, nodejs, nodejs:16, and postgresql-jdbc), Slackware (emacs and mozilla), SUSE (dav1d, ghostscript, go1.22, indent, kernel, openvswitch, PackageKit, python-uamqp, rubygem-rack-1_4, shadow, ucode-intel, xen, and zziplib), and Ubuntu (firefox, graphviz, libnet-cidr-lite-perl, and qpdf). --------------------------------------------- https://lwn.net/Articles/966611/ ∗∗∗ Firefox: Notfall-Update schließt kritische Sicherheitslücken ∗∗∗ --------------------------------------------- Die Mozilla-Entwickler haben zwei kritische Sicherheitslücken mit dem Update auf Firefox 124.0.1 und Firefox ESR 115.9.1 geschlossen. --------------------------------------------- https://heise.de/-9664148 ∗∗∗ Sicherheitslücken in Microsofts WiX-Installer-Toolset gestopft ∗∗∗ --------------------------------------------- Das quelloffene WiX-Installer-Toolset von Microsoft hat zwei Sicherheitslücken.

[..] While Sucuri's client was breached through a brute force attack, Sucuri has not shared how the other detected sites were compromised. However, based on previous WordPress attacks, it probably involves a combination of brute force attacks and exploiting plugin vulnerabilities to gain access to the site. --------------------------------------------- https://www.bleepingcomputer.com/news/security/evasive-sign1-malware-campai… ∗∗∗ AndroxGh0st Malware Targets Laravel Apps to Steal Cloud Credentials ∗∗∗ --------------------------------------------- Cybersecurity researchers have shed light on a tool referred to as AndroxGh0st thats used to target Laravel applications and steal sensitive data.

FalseFont is the latest tool in Curious Serpens’ arsenal. The examples we analyzed show how the threat actors mimic legitimate human resources software, using a fake job recruitment process to trick victims into installing the backdoor. --------------------------------------------- https://unit42.paloaltonetworks.com/curious-serpens-falsefont-backdoor/ ∗∗∗ Rescoms rides waves of AceCryptor spam ∗∗∗ --------------------------------------------- Insight into ESET telemetry statistics about AceCryptor in H2 2023 with a focus on Rescoms campaigns in European countries. --------------------------------------------- https://www.welivesecurity.com/en/eset-research/rescoms-rides-waves-acecryp… ∗∗∗ Warning Against Infostealer Disguised as Installer ∗∗∗ --------------------------------------------- The StealC malware disguised as an installer is being distributed en masse. It was identified as being downloaded via Discord, GitHub, Dropbox, etc. Considering the cases of distribution using similar routes, it is expected to redirect victims multiple times from a malicious webpage disguised as a download page for a certain program to the download URL. StealC is an Infostealer that extorts a variety of key information such as system, browser, cryptocurrency wallet, Discord, Telegram, and mail client data. --------------------------------------------- https://asec.ahnlab.com/en/63308/ ∗∗∗ New details on TinyTurla’s post-compromise activity reveal full kill chain ∗∗∗ --------------------------------------------- We now have new information on the entire kill chain this actor uses, including the tactics, techniques and procedures (TTPs) utilized to steal valuable information from their victims and propagate through their infected enterprises. --------------------------------------------- https://blog.talosintelligence.com/tinyturla-full-kill-chain/ ∗∗∗ The Updated APT Playbook: Tales from the Kimsuky threat actor group ∗∗∗ --------------------------------------------- In this blog we will detail new techniques that we have observed used by this actor group over the recent months.

[..] AcidPour shares many similarities with AcidRain, such as targeting specific directories and device paths common in embedded Linux distributions, but their codebase overlaps by an estimated 30%. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-acidpour-data-wiper-targ… ∗∗∗ Turnier verschoben: Mögliche RCE-Schwachstelle bedroht Apex-Legends-Spieler ∗∗∗ --------------------------------------------- Der weitverbreitete Free-to-play-Shooter Apex Legends steht derzeit im Verdacht, unter einer Sicherheitslücke zu leiden, die es Angreifern ermöglicht, aus der Ferne die Kontrolle über die Computer der Spieler zu übernehmen. Ob die Schwachstelle das Spiel selbst oder dessen Anti-Cheat-Software betrifft, ist wohl noch unklar. --------------------------------------------- https://www.golem.de/news/turnier-verschoben-moegliche-rce-schwachstelle-be… ∗∗∗ ARM MTE: Androids Hardwareschutz gegen Speicherlücken umgehbar ∗∗∗ --------------------------------------------- Mit dem Memory-Tagging moderner ARM-CPUs soll das Potenzial bestimmter Sicherheitslücken verkleinert werden. Die Idee hat deutliche Grenzen. Das Security-Forschungsteam des Code-Hosters Github hat die Ausnutzung einer Speicherlücke beschrieben, bei der der dafür eigentlich vorgesehene Schutz, das Memory-Tagging, offenbar gar keine Rolle spielt. Den Beteiligten ist es demnach gelungen, eine Sicherheitslücke in ARMs GPU-Treiber, die vollen Kernelzugriff und das Erlangen von Root-Rechten ermöglicht, auch auf einem aktuellen Pixel 8 auszunutzen, auf dem die sogenannten Memory Tagging Extension (MTE) aktiviert ist. --------------------------------------------- https://www.golem.de/news/arm-mte-androids-hardwareschutz-gegen-speicherlue… ∗∗∗ Threat landscape for industrial automation systems.

Your success in the ransomware or access broker ecosystem depends on having a consistently updated list of potential victims. As a result, certain IP addresses routinely scan the internet for specific types of vulnerabilities. One such example is 77.90.185.152. This IP address has been scanning for a different vulnerability each day. --------------------------------------------- https://isc.sans.edu/diary/rss/30758 ∗∗∗ New DEEP#GOSU Malware Campaign Targets Windows Users with Advanced Tactics ∗∗∗ --------------------------------------------- A new elaborate attack campaign has been observed employing PowerShell and VBScript malware to infect Windows systems and harvest sensitive information.
