Das Angebot: Sie helfen dabei, den Unternehmensauftritt bei Google zu verbessern, ein angebotenes Beratungsgespräch soll nach dem Gespräch bezahlt werden und koste einmalig bis zu 80 Euro. Doch weit gefehlt: Erfahrungsberichten zufolge tappt man hier in eine Abo-Falle, die nur schwer zu kündigen ist. --------------------------------------------- https://www.watchlist-internet.at/news/abzocke-google-praesenz/ ∗∗∗ Online scam taxonomy: the many ways to trick us ∗∗∗ --------------------------------------------- Because there are so many different types of online scams, we have compiled a list of scam taxonomy, shortly explaining what these scams mean.

===================== = End-of-Day report = ===================== Timeframe: Dienstag 05-03-2024 18:00 − Mittwoch 06-03-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: Thomas Pribitzer ===================== = News = ===================== ∗∗∗ Why Your Firewall Will Kill You, (Tue, Mar 5th) ∗∗∗ --------------------------------------------- The last few years have been great for attackers exploiting basic web application vulnerabilities. Usually, home and small business products from companies like Linksys, D-Link, and Ubiquity are known to be favorite targets. But over the last couple of years, enterprise products from companies like Ivanti, Fortigate, Sonicwall, and Citrix (among others) have become easy to exploit targets. The high value of the networks protected by these "solutions" has made them favorites for ransomware attackers. --------------------------------------------- https://isc.sans.edu/diary/rss/30714 ∗∗∗ Scanning and abusing the QUIC protocol, (Wed, Mar 6th) ∗∗∗ --------------------------------------------- The QUIC protocol has slowly (pun intended) crawled into our browsers and many other protocols. Last week, at BSides Zagreb I presented some research I did about applications using (and abusing) this protocol, so it made sense to put this into one diary. --------------------------------------------- https://isc.sans.edu/diary/rss/30720 ∗∗∗ Living off the land with native SSH and split tunnelling ∗∗∗ --------------------------------------------- Lately I was involved in an assumed compromise project where stealth and simplicity was required, reducing the opportunity to use a sophisticated C2 infrastructure. We did note that the built-in Windows SSH client could make this simpler for us. [..] Windows native SSH can be a convenient attack path IF an organisation doesn’t have the ability to block and monitor the forwarded internal traffic. [..] The obvious route is to restrict access to the SSH command for all users who don’t have a business need, or to uninstall it from your default Windows build and use something like PuTTY instead. --------------------------------------------- https://www.pentestpartners.com/security-blog/living-off-the-land-with-nati… ∗∗∗ Schneeballsystem-Alarm bei DCPTG.com! ∗∗∗ --------------------------------------------- An die Watchlist Internet wird aktuell vermehrt ein Schneeball- bzw. Pyramidensystem mit dem Namen dcptg.com gemeldet. Versprochen werden Erfahrungsberichten nach völlig unrealistische und risikofreie Gewinnmöglichkeiten von 2 bis 5 Prozent des eingesetzten Kapitals pro Tag. Außerdem müssen laufend weitere Menschen angeworben werden, um langfristig an dem System teilnehmen zu können. Vorsicht: DCPTG.com ist betrügerisch! --------------------------------------------- https://www.watchlist-internet.at/news/schneeballsystem-alarm-bei-dctpgcom/ ∗∗∗ Fake-Gewinnspiel im Namen vom Tiergarten Schönbrunn ∗∗∗ --------------------------------------------- Über ein Fake-Profil des Tiergartens Schönbrunn wird derzeit ein betrügerisches Gewinnspiel auf Facebook verbreitet. Die Facebook-Seite „Tiergarten Wien“ verlost angeblich 4 Eintrittskarten. Sie müssen lediglich die Versandgebühren für die Karten bezahlen. Vorsicht: Sie tappen in eine Abo-Falle und geben Ihre persönlichen Daten an Kriminelle weiter. --------------------------------------------- https://www.watchlist-internet.at/news/fake-gewinnspiel-im-namen-vom-tierga… ∗∗∗ Whoops! ACEMAGIC ships mini PCs with free bonus pre-installed malware ∗∗∗ --------------------------------------------- Chinese mini PC manufacturer ACEMAGIC has made life a bit more interesting for its customers, by admitting that it has also been throwing in free malware with its products. --------------------------------------------- https://grahamcluley.com/whoops-acemagic-ships-mini-pcs-with-free-bonus-pre… ∗∗∗ Data Exfiltration: Increasing Number of Tools Leveraged by Ransomware Attackers ∗∗∗ --------------------------------------------- Ransomware actors are deploying a growing array of data-exfiltration tools in their attacks and, over the past three months alone, Symantec has found attackers using at least dozen different tools capable of data exfiltration. While some exfiltration tools are malware, the vast majority are dual-use – legitimate software used by the attackers for malicious purposes. --------------------------------------------- https://symantec-enterprise-blogs.security.com/threat-intelligence/ransomwa… ∗∗∗ Badgerboard: A PLC backplane network visibility module ∗∗∗ --------------------------------------------- Analysis of the traffic between networked devices has always been of interest since devices could even communicate with one another. As the complexity of networks grew, the more useful dedicated traffic analysis tools became. Major advancements have been made over the years with tools like Snort or Wireshark, but these tools are only useful when accurate information is provided to them. By only sending a subset of the information being passed across a network to monitoring tools, analysts will be provided with an incomplete picture of the state of their network. --------------------------------------------- https://blog.talosintelligence.com/badgerboard-research/ ∗∗∗ Coper / Octo - A Conductor for Mobile Mayhem… With Eight Limbs? ∗∗∗ --------------------------------------------- In this blog post, we will detail our analysis and understanding of the Coper/Octo Android malware, examining the malware’s continued development, as well as providing insights into attack patterns, infrastructure utilization and management, and hunting tips. --------------------------------------------- https://www.team-cymru.com/post/coper-octo-a-conductor-for-mobile-mayhem-wi… ∗∗∗ New Linux Malware Alert: ‘Spinning YARN’ Hits Docker, Other Key Apps ∗∗∗ --------------------------------------------- According to Cado Security’s research research shared with Hackread.com ahead of publication on Wednesday, Spinning Yarn is a malicious campaign that exploits weaknesses in popular Linux software used by businesses across various sectors. --------------------------------------------- https://www.hackread.com/new-linux-malware-alert-spinning-yarn-docker-apps/ ∗∗∗ Fritz.box: Domain aus dem Verkehr gezogen ∗∗∗ --------------------------------------------- Unbekannte sicherten sich im Januar die Domain fritz.box.

VMware has evaluated the severity of this issue to be in the Critical severity range with a maximum CVSSv3 base score of 9.3 for Workstation/Fusion and in the Important severity range with a maximum CVSSv3 base score of 8.4 for ESXi. [..] A malicious actor with local administrative privileges on a virtual machine may exploit this issue to execute code as the virtual machine's VMX process running on the host. On ESXi, the exploitation is contained within the VMX sandbox whereas, on Workstation and Fusion, this may lead to code execution on the machine where Workstation or Fusion is installed. --------------------------------------------- https://www.vmware.com/security/advisories/VMSA-2024-0006.html ∗∗∗ Security updates for Wednesday ∗∗∗ --------------------------------------------- Security updates have been issued by Debian (libapache2-mod-auth-openidc, libuv1, php-phpseclib, and phpseclib), Red Hat (buildah, cups, curl, device-mapper-multipath, emacs, fence-agents, frr, fwupd, gmp, gnutls, golang, haproxy, keylime, libfastjson, libmicrohttpd, linux-firmware, mysql, openssh, rear, skopeo, sqlite, squid, systemd, and tomcat), Slackware (mozilla), SUSE (kernel-firmware-nvidia-gspx-G06, nvidia-open- driver-G06-signed, postgresql-jdbc, python, python-cryptography, rubygem-rack, wpa_supplicant, and xmlgraphics-batik), and Ubuntu (c-ares, firefox, libde265, libgit2, and ruby-image-processing). --------------------------------------------- https://lwn.net/Articles/964559/ ∗∗∗ CISA Adds Two Known Exploited Vulnerabilities to Catalog ∗∗∗ --------------------------------------------- CVE-2024-23225 / CVE-2024-23296 Apple iOS and iPadOS Memory Corruption Vulnerability --------------------------------------------- https://www.cisa.gov/news-events/alerts/2024/03/06/cisa-adds-two-known-expl… ∗∗∗ Foxit: Sicherheitsupdates in Foxit PDF Reader 2024.1 und Foxit PDF Editor 2024.1 verfügbar ∗∗∗ --------------------------------------------- https://www.foxit.com/de/support/security-bulletins.html ∗∗∗ IBM Security Bulletins ∗∗∗ --------------------------------------------- https://www.ibm.com/support/pages/bulletin/ ∗∗∗ Bosch: Git for Windows Multiple Security Vulnerabilities in Bosch DIVAR IP all-in-one Devices ∗∗∗ --------------------------------------------- https://psirt.bosch.com/security-advisories/bosch-sa-637386-bt.html ∗∗∗ Bosch: Multiple OpenSSL vulnerabilities in BVMS ∗∗∗ --------------------------------------------- https://psirt.bosch.com/security-advisories/bosch-sa-090577-bt.html ∗∗∗ F5: K000138827 : OpenSSH vulnerability CVE-2023-51385 ∗∗∗ --------------------------------------------- https://my.f5.com/manage/s/article/K000138827 ∗∗∗ iOS 17.4 und iOS 16.7.6: Wichtige sicherheitskritische Bugfixes ∗∗∗ --------------------------------------------- https://heise.de/-9647164 -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily

This long-standing malware campaign leverages a JavaScript malware framework that has been in use since at least 2017. The malware attempts to trick unsuspecting users into downloading what is actually a Remote Access Trojan (RAT) onto their computers, which is often the first stage in a ransomware infection. Late last week our incident response team identified a fresh wave of SocGholish (fake browser update) infections targeting WordPress websites. --------------------------------------------- https://blog.sucuri.net/2024/03/new-wave-of-socgholish-infections-impersona… ∗∗∗ Rise in Deceptive PDF: The Gateway to Malicious Payloads ∗∗∗ --------------------------------------------- McAfee Labs has recently observed a significant surge in the distribution of prominent malware through PDF files. Malware is not solely sourced from dubious websites or downloads; certain instances of malware may reside within apparently harmless emails, particularly within the PDF file attachments accompanying them.

Diese heterogene Bedrohungslage bedingt zur Abklärung einer bereits stattgefundenen Kompromittierung auch einen abstrahierten Blick auf etwaige eigene Installationen. Sophos beschreibt in den Kapiteln "Recommendations" und "Threat hunting information" Empfehlungen zur Vorgangsweise, selbst betriebene Instanzen auf Kompromittierungen zu untersuchen.

[..] Die von Checkpoint Security aufgedeckte Schwachstelle ermöglicht einem Angreifer die geschützte Office-Ansicht zu umgehen und das Dokument im Bearbeitungsmodus statt im geschützten Modus zu öffnen. [..] Dazu muss der Angreifer einen bösartigen Link erstellen, der das Protected View-Protokoll umgeht.

===================== = End-of-Day report = ===================== Timeframe: Montag 12-02-2024 18:00 − Dienstag 13-02-2024 18:00 Handler: Thomas Pribitzer Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ The (D)Evolution of Pikabot ∗∗∗ --------------------------------------------- Pikabot is a malware loader that originally emerged in early 2023. Over the past year, ThreatLabz has been tracking the development of Pikabot and its modus operandi. There was a significant increase in usage in the second half of 2023 following the FBI-led takedown of Qakbot. This was likely the result of a BlackBasta ransomware affiliate replacing Qakbot with Pikabot for initial access. However, Pikabot ceased activity shortly after Christmas 2023, with its version number being 1.1.19 at that time. In recent campaigns, which started in February 2024, Pikabot reemerged with significant changes in its code base and structure. --------------------------------------------- https://www.zscaler.com/blogs/security-research/d-evolution-pikabot ∗∗∗ GMX, Web.de, Online-Dienste: Angriffe auf Zugangsdaten nehmen zu ∗∗∗ --------------------------------------------- Etwas alarmistisch melden einige Medien, dass es vermehrt Angriffe auf Zugangskonten von GMX oder Web.de gebe, die unter anderem sehr populäre Webmail-Dienste bereitstellen. Es werden dort bei zahlreichen Konten sehr hohe Zahlen für fehlerhafte Log-in-Versuche angezeigt. Es handelt sich offenbar um die alltäglichen Angriffe auf Zugangsdaten von Cyberkriminellen, die versuchen, mit gestohlenen Accountinformationen auf Online-Dienste zuzugreifen. --------------------------------------------- https://www.heise.de/-9626994 ∗∗∗ Vorsicht vor gefälschten WKÖ-E-Mails ∗∗∗ --------------------------------------------- Kriminelle geben sich als Wirtschaftskammer Österreich aus und bitten Unternehmen in einem E-Mail, Kontaktdaten zu aktualisieren. Klicken Sie keinesfalls auf den Link, Sie werden auf eine gefälschte WKÖ-Seite geführt. Dort stehlen Kriminelle Firmen- und Bankdaten. --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-gefaelschten-wkoe-e-mai… ∗∗∗ Directory.ReadWrite.All Is Not As Powerful As You Might Think ∗∗∗ --------------------------------------------- Directory.ReadWrite.All is an MS Graph permission that is frequently cited as granting high amounts of privilege, even being equated to the Global Admin Entra ID role [..] Misleading or incorrect documentation create most of the misconceptions regarding this permission. --------------------------------------------- https://posts.specterops.io/directory-readwrite-all-is-not-as-powerful-as-y… ∗∗∗ Ongoing Microsoft Azure account hijacking campaign targets executives ∗∗∗ --------------------------------------------- A phishing campaign detected in late November 2023 has compromised hundreds of user accounts in dozens of Microsoft Azure environments, including those of senior executives. --------------------------------------------- https://www.bleepingcomputer.com/news/security/ongoing-microsoft-azure-acco… ∗∗∗ Fileless Revenge RAT Malware ∗∗∗ --------------------------------------------- AhnLab SEcurity intelligence Center (ASEC) recently discovered the distribution of Revenge RAT malware that had been developed based on legitimate tools. It appears that the attackers have used tools such as ‘smtp-validator’ and ‘Email To Sms’. At the time of execution, the malware creates and runs both a legitimate tool and a malicious file, making it difficult for users to realize that a malicious activity has occurred. --------------------------------------------- https://asec.ahnlab.com/en/61584/ ===================== = Vulnerabilities = ===================== ∗∗∗ Request Tracker Write-up (CVE-2023-41259, CVE-2023-41260) ∗∗∗ --------------------------------------------- Without authentication we were able to extract file-attachments that were uploaded to RT, including e-mails received from and to users regarding tickets and issues. We also found it was possible to obtain information about tickets and users. --------------------------------------------- https://www.linkedin.com/pulse/request-tracker-write-up-tom-wolters-ygsae ∗∗∗ PowerDNS Security Advisory 2024-01: crafted DNSSEC records in a zone can lead to a denial of service in Recursor ∗∗∗ --------------------------------------------- An attacker can publish a zone that contains crafted DNSSEC related records. While validating results from queries to that zone using the RFC mandated algorithms, the Recursor’s resource usage can become so high that processing of other queries is impacted, resulting in a denial of service. Note that any resolver following the RFCs can be impacted, this is not a problem of this particular implementation. --------------------------------------------- https://doc.powerdns.com/recursor/security-advisories/powerdns-advisory-202… ∗∗∗ DNS-Server: Bind und Unbound stolpern über Sicherheitslücke "KeyTrap" ∗∗∗ --------------------------------------------- Mit einer präparierten DNS-Anfrage können Angreifer eine hohe Prozessorlast verursachen und den Dienst für legitime Nutzer so blockieren. Patches stehen bereit. --------------------------------------------- https://www.heise.de/-9627276 ∗∗∗ Sicherheitslücken: Angreifer können Dell Unity kompromittieren ∗∗∗ --------------------------------------------- Die Fehler stecken in Dell Unity Operating Enviroment (OE). Die Entwickler geben an, die Ausgabe 5.4.0.0.5.094 repariert zu haben. Von den Sicherheitsproblemen sind unter anderem Dell EMC Unity, Dell EMC Unity XT 380F und Dell EMC Unity Hybrid betroffen. Alle verwundbaren Produkte sind in der Warnmeldung aufgelistet. --------------------------------------------- https://www.heise.de/-9626407 ∗∗∗ Qnap: Sicherheitslücken in Firmware erlauben Einschleusen von Befehlen ∗∗∗ --------------------------------------------- In der Sicherheitswarnung schreibt Qnap, dass es sich um zwei Schwachstellen handelt. Die Beschreibung für beide lautet: Eine Befehlsschmuggel-Schwachstelle wurde in mehreren Qnap-Betriebssystemversionen gemeldet. Sofern sie missbraucht werden, erlauben sie Nutzern, Befehle über das Netzwerk auszuführen (CVE-2023-47218, CVE-2023-50358, CVSS 5.8, Risiko "mittel"). --------------------------------------------- https://www.heise.de/-9626319 ∗∗∗ SAP patcht: 13 Sicherheitslücken abgedichtet ∗∗∗ --------------------------------------------- SAP verteilt Software-Updates, die Schwachstellen aus 13 Sicherheitsmitteilungen ausbessern.

We had a very limited set of top-level domains: .com, .edu, .gov, ..int, org, .mil, .net, .org, .edu. In addition, we had .arpa for infrastructure use and various two letter country level domains.

When users log in, they will be redirected to the external IdP for authentication, before being redirected back to Entra ID who will then verify the successful authentication on the external IdP and the user’s identity. [..] The external IdP signs the token with a private key, which has an associated public key stored in a certificate. [..] In this post, I’ll show you where this certificate can be found and how attackers can add it (given the necessary privileges) and use it to forge malicious tokens. Finally, I will provide some recommendations for defense in light of this. --------------------------------------------- https://medium.com/tenable-techblog/stealthy-persistence-privesc-in-entra-i… ∗∗∗ OAS Engine Deep Dive: Abusing low-impact vulnerabilities to escalate privileges ∗∗∗ --------------------------------------------- Open Automation Software recently released patches for multiple vulnerabilities in their OAS Engine. Cisco Talos publicly disclosed these issues after working with Open Automation Software to ensure that patches were available for users. Now that a fix has been released with Version 19, we want to take the time to dive into a few of these vulnerabilities and show how a handful of bugs that could be viewed as low-impact could be exploited as a series to carry out various malicious actions, even going as far to gaining access to the underlying system. --------------------------------------------- https://blog.talosintelligence.com/oas-engine-deep-dive/ ===================== = Vulnerabilities = ===================== ∗∗∗ Mastodon: Diebstahl beliebiger Identitäten im föderierten Kurznachrichtendienst ∗∗∗ --------------------------------------------- Angreifer können jeden beliebigen Account übernehmen und fälschen. [..] Die Sicherheitslücke hat die CVE-ID CVE-2024-23832 erhalten und hat immerhin 9,4 von 10 CVSS-Punkten. Es handelt sich nach Einschätzung des Mastodon-Teams um eine leicht aus der Ferne ausnutzbare Lücke, die keinerlei Vorbedingungen mitbringt. Weder muss der Angreifer über besondere Privilegien verfügen, noch einen legitimen Nutzer austricksen, etwa mit einem gefälschten Link. Weitere Details verraten die Entwickler erst am 15.

===================== = End-of-Day report = ===================== Timeframe: Montag 13-11-2023 18:00 − Dienstag 14-11-2023 18:00 Handler: Stephan Richter Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ CISA warns of actively exploited Juniper pre-auth RCE exploit chain ∗∗∗ --------------------------------------------- CISA warned federal agencies today to secure Juniper devices on their networks by Friday against four vulnerabilities now used in remote code execution (RCE) attacks as part of a pre-auth exploit chain. The alert comes one week after Juniper updated its advisory to notify customers that the flaws found in Juniper's J-Web interface (tracked as CVE-2023-36844, CVE-2023-36845, CVE-2023-36846, and CVE-2023-36847) have been successfully exploited in the wild. --------------------------------------------- https://www.bleepingcomputer.com/news/security/cisa-warns-of-actively-explo… ∗∗∗ ChatGPT, Bard und andere: KI-Systeme ermöglichen Ausleiten von Daten ∗∗∗ --------------------------------------------- Durch gezielte Abfragen lassen sich private und geschützte Daten aus KI-Systemen ausleiten.

Some of them can be noticed because they perform DNS lookup and some of them initiates connection without DNS lookup. For this last option, this is abnormal and can be noticed by any Network Detection and Response (NDR) tool that reviews the network traffic by at least two weeks. Most companies do not have money to afford a NDR, so I'm going to show you today an interesting tip that have worked for me to notice APT calling home when they perform DNS lookup. --------------------------------------------- https://isc.sans.edu/diary/rss/30396 ∗∗∗ Bug hunters on your marks: TETRA radio encryption algorithms to enter public domain ∗∗∗ --------------------------------------------- The algorithms are used by TETRA – short for the Terrestrial Trunked Radio protocol – and they are operated by governments, law enforcement, military and emergency services organizations in Europe, the UK, and other countries. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2023/11/14/tetra_encryp… ∗∗∗ Novel backdoor persists even after critical Confluence vulnerability is patched ∗∗∗ --------------------------------------------- Got a Confluence server?

Python offers three libraries shipped with a standard installation for handling e-mail transfer. These modules are smtplib, imaplib, and poplib. While Python programming is usually straightforward, using these Python libraries require passing a magic parameter in the right way to use secure communication. --------------------------------------------- https://www.pentagrid.ch/en/blog/python-mail-libraries-certificate-verifica… ∗∗∗ LockBit ransomware group assemble strike team to breach banks, law firms and governments. ∗∗∗ --------------------------------------------- [...] I thought it would be good to break down what is happening and how they’re doing it, since LockBit are breaching some of the world’s largest organisations - many of whom have incredibly large security budgets. Through data allowing the tracking of ransomware operators, it has been possible to track individual targets. Recently, it has become clear they have been targeting a vulnerability in Citrix Netscaler, called CitrixBleed. --------------------------------------------- https://doublepulsar.com/lockbit-ransomware-group-assemble-strike-team-to-b… ∗∗∗ CVE Half-Day Watcher ∗∗∗ --------------------------------------------- CVE Half-Day Watcher is a security tool designed to highlight the risk of early exposure of Common Vulnerabilities and Exposures (CVEs) in the public domain. It leverages the National Vulnerability Database (NVD) API to identify recently published CVEs with GitHub references before an official patch is released. By doing so, CVE Half-Day Watcher aims to underscore the window of opportunity for attackers to "harvest" this information and develop exploits. --------------------------------------------- https://github.com/Aqua-Nautilus/CVE-Half-Day-Watcher ∗∗∗ Vorsicht vor Jobangeboten per SMS oder WhatsApp ∗∗∗ --------------------------------------------- Unerwartet erhalten Sie eine Nachricht von einer Personalvermittlungsagentur: Ihnen wird ein Job angeboten.

Ignorieren Sie dieses Jobangebot, es handelt sich um Betrug! --------------------------------------------- https://www.watchlist-internet.at/news/vorsicht-vor-jobangeboten-per-sms-od… ∗∗∗ Ddostf DDoS Bot Malware Attacking MySQL Servers ∗∗∗ --------------------------------------------- The ASEC analysis team has recently discovered that the Ddostf DDoS bot is being installed on vulnerable MySQL servers. Ddostf is a DDoS bot capable of conducting Distributed Denial of Service (DDoS) attacks on specific targets and was first identified around 2016. --------------------------------------------- https://asec.ahnlab.com/en/58878/ ∗∗∗ A Closer Look at ChatGPTs Role in Automated Malware Creation ∗∗∗ --------------------------------------------- This blog entry explores the effectiveness of ChatGPTs safety measures, the potential for AI technologies to be misused by criminal actors, and the limitations of current AI models. --------------------------------------------- https://www.trendmicro.com/en_us/research/23/k/a-closer-look-at-chatgpt-s-r… ∗∗∗ Malicious Abrax666 AI Chatbot Exposed as Potential Scam ∗∗∗ --------------------------------------------- As of now, based on the information regarding the sale of the Abrax666 AI Chatbot, cybersecurity researchers are of the opinion that the chatbot is most likely a scam. --------------------------------------------- https://www.hackread.com/abrax666-ai-chatbot-exposed-as-potential-scam/ ===================== = Vulnerabilities = ===================== ∗∗∗ Siemens Security Advisories ∗∗∗ --------------------------------------------- Siemens has released 14 new and 18 updated Security Advisories. --------------------------------------------- https://www.siemens.com/global/en/products/services/cert.html?d=2023-11#Sie… ∗∗∗ Xen Security Advisory CVE-2023-46835 / XSA-445 - x86/AMD: mismatch in IOMMU quarantine page table levels ∗∗∗ --------------------------------------------- A device in quarantine mode can access data from previous quarantine page table usages, possibly leaking data used by previous domains that also had the device assigned. --------------------------------------------- https://xenbits.xen.org/xsa/advisory-445.html ∗∗∗ Xen Security Advisory CVE-2023-46836 / XSA-446 - x86: BTC/SRSO fixes not fully effective ∗∗∗ --------------------------------------------- An attacker in a PV guest might be able to infer the contents of memory belonging to other guests. --------------------------------------------- https://xenbits.xen.org/xsa/advisory-446.html ∗∗∗ SAP Security Patch Day –November2023 ∗∗∗ --------------------------------------------- On 14th of November 2023, SAP Security Patch Day saw the release of 3 new Security Notes.

The attack can be launched as long as the victim opens an .accdb or .mdb file. In fact, any more-common Office file type (such as a .rtf ) can work as well 4.

The threat actor is distributing a legitimate EXE file with a valid signature and a malicious DLL compressed in the same directory. The EXE file itself is legitimate, but when executed in the same directory as the malicious DLL, it automatically runs that malicious DLL. This technique is called DLL hijacking and is often used in the distribution of malware. --------------------------------------------- https://asec.ahnlab.com/en/58319/ ∗∗∗ Attackers use JavaScript URLs, API forms and more to scam users in popular online game “Roblox” ∗∗∗ --------------------------------------------- Where there is a potential for profit there are also people trying to scam others. “Roblox” users can be targeted by scammers (known as “beamers” by “Roblox” players) who attempt to steal valuable items or Robux from other players. This can sometimes be made easier for the scammers because of “Roblox's” young user base. Nearly half of the game’s 65 million users are under the age of 13 who may not be as adept at spotting scams. --------------------------------------------- https://blog.talosintelligence.com/roblox-scam-overview/ ∗∗∗ Suspected Exploitation of Apache ActiveMQ CVE-2023-46604 ∗∗∗ --------------------------------------------- Beginning Friday, October 27, Rapid7 Managed Detection and Response (MDR) identified suspected exploitation of Apache ActiveMQ CVE-2023-46604 in two different customer environments. In both instances, the adversary attempted to deploy ransomware binaries on target systems in an effort to ransom the victim organizations. Based on the ransom note and available evidence, we attribute the activity to the HelloKitty ransomware family, whose source code was leaked on a forum in early October. Rapid7 observed similar indicators of compromise across the affected customer environments, both of which were running outdated versions of Apache ActiveMQ. --------------------------------------------- https://www.rapid7.com/blog/post/2023/11/01/etr-suspected-exploitation-of-a… ===================== = Vulnerabilities = ===================== ∗∗∗ Unpatched Powerful SSRF in Exchange OWA – Getting Response Through Attachments ∗∗∗ --------------------------------------------- As the attacker can abuse this SSRF to retrieve the content of the response, I thought it was a good finding. However, Microsoft did not agree [...] In short: this may get fixed or it may not. If they decide to fix it, the patch may appear in 1 year or in 3 years. In general, we know nothing. Accordingly, we informed Microsoft of our intention to publish this vulnerability as a 0-day advisory and a blog post. As we consider this issue potentially dangerous, we want organizations to be aware of the threat.

All the scripts that I recently spotted were always the same: a classic intostealer using Discord as C2 channel. Today I found one that contains a lot of anti-sanboxing techniques. Let's review them. For malware, it's key to detect the environment where they are executed.

During a lengthy outage, I decided to redo some of my network configurations. As part of this change, I also reorganized my IPv6 setup, relying more on DHCPv6 and less on router advertisements to configure IPv6 addresses. Overall, this worked well. My Macs had no issues connecting to IPv6. However, the Linux host I use to alert me of network connectivity issues could not "ping" the test host via IPv6. --------------------------------------------- https://isc.sans.edu/diary/rss/30336 ∗∗∗ Tampered OpenCart Authentication Aids Credit Card Skimming Attack ∗∗∗ --------------------------------------------- Using out of date software is the leading cause of website compromise, so keeping your environment patched and up to date is one of the most important responsibilities of a website administrator. It’s not uncommon to employ the use of custom code on websites, and spend small fortunes on software developers to tailor their website just the way they want it. However, the usage of customised code can sometimes inadvertently lock a website administrator into using an out of date CMS installation long after its expiry date, particularly if they no longer have access to their old developer (or sufficient funds to hire a new one). --------------------------------------------- https://blog.sucuri.net/2023/10/tampered-opencart-authentication-aids-credi… ∗∗∗ Abusing gdb Features for Data Ingress & Egress ∗∗∗ --------------------------------------------- As of November 2019, elfutils supports debuginfod, a client/server protocol that enables debuggers (gdb) to fetch debugging symbols via HTTP/HTTPs from a user-specified remote server. This blog post will demonstrate how this feature of gdb can be abused to create data communication paths for data exfiltration and tool ingress. --------------------------------------------- https://www.archcloudlabs.com/projects/debuginfod/ ∗∗∗ Vorsicht vor Jobangeboten auf WhatsApp oder Telegram ∗∗∗ --------------------------------------------- Sie suchen gerade einen Job? Praktisch, wenn Sie gar nicht suchen müssen und Sie direkt auf WhatsApp oder Telegram einen Job angeboten bekommen. Dahinter stecken aber Kriminelle, die Ihnen z. B. einen „Datenoptimierungsjob mit möglichen Provisionen“ anbieten.

Forensic analysis conducted by an independent, third party indicates that no customer operations or Autodesk products were disrupted due to this incident. --------------------------------------------- https://www.autodesk.com/trust/security-advisories/adsk-sa-2023-0020 ∗∗∗ Kritische Sicherheitslücke in Cisco IOS XE - aktiv ausgenützt ∗∗∗ --------------------------------------------- Update: 23. Oktober 2023 Cisco hat für einige der von der Schwachstelle betroffenen Geräte Aktualisierungen veröffentlicht, und weitere Updates angekündigt. Das Unternehmen aktualisiert die Liste an verfügbaren Patches auf einer dedizierten Seite laufend. Wenn das Management-WebInterface eines Cisco XE Gerätes vor dem Einspielen des Updates offen im Netz erreichbar war, ist davon auszugehen, dass ein Angreifer dies ausgenutzt hat und zumindest neue Admin-Accounts angelegt hat. Damit ist die Installation von weiteren Hintertüren möglich, die - aus heutiger Sicht - nur mit einem Factory Reset / Neuinstallation von IOS XE umfassend entfernt werden können --------------------------------------------- https://cert.at/de/warnungen/2023/10/kritische-sicherheitslucke-in-cisco-io… ===================== = Vulnerabilities = ===================== ∗∗∗ Multiple Vulnerabilities in Cisco IOS XE Software Web UI Feature ∗∗∗ --------------------------------------------- Version 1.4: Updated the summary to indicate the first fixes are available.
