We now know the remote code execution vulnerability in Apache Struts 2 disclosed back in November carries a near-maximum severity rating following the publication of the CVE. [..] Considering remote attackers could exploit the vulnerability without requiring any privileges, combined with the high impact to system confidentiality, integrity, and availability, it's likely the Apache Foundation withheld the juiciest details to allow customers to upgrade to a safe version (Struts 6.4.0 or greater). --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2024/12/12/apache_strut… ∗∗∗ Cyber Resilience Act: Vernetzte Produkte müssen bald besser abgesichert sein ∗∗∗ --------------------------------------------- Die EU-Verordnung zur Cyber-Widerstandsfähigkeit ist in Kraft getreten.

While investigating a WordPress site infection, WPScan discovered active exploitation of CVE-2024-11972 to install a vulnerable version of WP Query Console. [..] By installing outdated plugins with known vulnerabilities with available exploits, the attackers can access a large pool of flaws that lead to remote code execution (RCE), SQL injection, cross-site scripting (XSS) flaws, or create backdoor admin accounts. --------------------------------------------- https://www.bleepingcomputer.com/news/security/hunk-companion-wordpress-plu… ∗∗∗ Apple Updates Everything (iOS, iPadOS, macOS, watchOS, tvOS, visionOS), (Wed, Dec 11th) ∗∗∗ --------------------------------------------- Apple today released patches for all of its operating systems. The updates address 46 different vulnerabilities. Many of the vulnerabilities affect more than one operating system. None of the vulnerabilities are labeled as being already exploited. --------------------------------------------- https://isc.sans.edu/diary/rss/31514 ∗∗∗ Atlassian schützt Confluence & Co. vor möglichen DoS-Attacken ∗∗∗ --------------------------------------------- Angreifer können an zehn Sicherheitslücken in Atlassian Bamboo, Bitbucket und Confluence ansetzen und unter anderem Abstürze provozieren. --------------------------------------------- https://heise.de/-10196643 ∗∗∗ Sicherheitspatch: Angreifer können über TeamViewer-Lücke Windows-Dateien löschen ∗∗∗ --------------------------------------------- Basierend auf einer Warnmeldung ist die Komponente TeamViewer Patch & Asset Management angreifbar (CVE-2024-12363 "hoch").

[..] One of the most popular requests has been the capability to use Dissect in combination with common disk encryption methods like Microsoft’s BitLocker or its Linux equivalent LUKS. Internally at Fox-IT we were able to already use these capabilities. With the release of Dissect version 3.17 these capabilities are now also available to the community at large. --------------------------------------------- https://blog.fox-it.com/2024/12/11/decrypting-full-disk-encryption-with-dis… ∗∗∗ The Stealthy Stalker: Remcos RAT ∗∗∗ --------------------------------------------- As cyberattacks become more sophisticated, understanding the mechanisms behind RemcosRAT and adopting effective security measures are crucial to protecting your systems from this growing threat.

===================== = End-of-Day report = ===================== Timeframe: Dienstag 03-12-2024 18:00 − Mittwoch 04-12-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Supply Chain Attack Detected in Solanas web3.js Library ∗∗∗ --------------------------------------------- A supply chain attack has been detected in versions 1.95.6 and 1.95.7 of the popular @solana/web3.js library, which receives more than ~350,000 weekly downloads on npm. These compromised versions contain injected malicious code that is designed to steal private keys from unsuspecting developers and users, potentially enabling attackers to drain cryptocurrency wallets. [..] npm has moved swiftly to remove the affected versions. [..] Anza recommends developers who suspect they were compromised to rotate any suspect authority keys, including multisigs, program authorities, and server keypairs. --------------------------------------------- https://socket.dev/blog/supply-chain-attack-solana-web3-js-library ∗∗∗ Jetzt patchen! Exploit für kritische Lücke in Whatsup Gold in Umlauf ∗∗∗ --------------------------------------------- Eine "kritische" Sicherheitslücke ist seit September dieses Jahres bekannt. Seitdem gibt es auch ein Sicherheitsupdate. Weil mittlerweile Exploitcode für die Schwachstelle kursiert, könnten Attacken bevorstehen. --------------------------------------------- https://heise.de/-10187538 ∗∗∗ Cisco Urges Immediate Patch for Decade-Old WebVPN Vulnerability ∗∗∗ --------------------------------------------- Cisco recently updated an advisory about a security flaw in the WebVPN login page of their ASA software, which can allow an unauthenticated, remote attacker to execute a cross-site scripting (XSS) attack on anyone using WebVPN on the Cisco ASA. [..] The vulnerability itself isn’t new – Cisco originally issued a warning back in March 2014. However, the company’s recent update highlights a concerning development: attackers are actively trying to exploit this decade-old bug. --------------------------------------------- https://hackread.com/cisco-patch-decade-old-webvpn-vulnerability/ ∗∗∗ (QR) Coding My Way Out of Here: C2 in Browser Isolation Environments ∗∗∗ --------------------------------------------- In this blog post, Mandiant demonstrates a novel technique that can be used to circumvent all three current types of browser isolation (remote, on-premises, and local) for the purpose of controlling a malicious implant via C2. Mandiant shows how attackers can use machine-readable QR codes to send commands from an attacker-controlled server to a victim device. --------------------------------------------- https://cloud.google.com/blog/topics/threat-intelligence/c2-browser-isolati… ∗∗∗ Wegem schwerem Cyberangriff auf US-Provider: FBI wirbt für Verschlüsselung ∗∗∗ --------------------------------------------- Angesichts eines verheerenden Cyberangriffs auf US-Provider haben die US-Bundespolizei FBI und die Cybersicherheitsbehörde CISA die Menschen in den Vereinigten Staaten aufgefordert, ihre Kommunikation möglichst zu verschlüsseln. --------------------------------------------- https://heise.de/-10187110 ∗∗∗ Black Basta Ransomware Campaign Drops Zbot, DarkGate, and Custom Malware ∗∗∗ --------------------------------------------- Beginning in early October, Rapid7 has observed a resurgence of activity related to the ongoing social engineering campaign being conducted by Black Basta ransomware operators. --------------------------------------------- https://www.rapid7.com/blog/post/2024/12/04/black-basta-ransomware-campaign… ∗∗∗ PROXY.AM Powered by Socks5Systemz Botnet ∗∗∗ --------------------------------------------- After a year long investigation, Bitsight TRACE follows up on Socks5Systemz research. --------------------------------------------- https://www.bitsight.com/blog/proxyam-powered-socks5systemz-botnet ∗∗∗ New era of slop security reports for open source ∗∗∗ --------------------------------------------- Recently I've noticed an uptick in extremely low-quality, spammy, and LLM-hallucinated security reports to open source projects. [..] Security reports that waste maintainers' time result in confusion, stress, frustration, and to top it off a sense of isolation due to the secretive nature of security reports. [..] If this is happening to a handful of projects that I have visibility for, then I suspect that this is happening on a large scale to open source projects. This is a very concerning trend. --------------------------------------------- https://sethmlarson.dev/slop-security-reports ===================== = Vulnerabilities = ===================== ∗∗∗ Identitätsmanagement: Sicherheitslücke mit Höchstwertung bedroht IdentityIQ ∗∗∗ --------------------------------------------- Bislang gibt es von SailPoint noch keine Warnung zur Sicherheitslücke. Alle Informationen zur "kritischen" Schwachstelle (CVE-2024-10905) basieren derzeit auf einem Eintrag in der National Vulnerability Database (NVD) des National Insitute of Standards and Technology (NIST). [..] Die Lücke soll in den Ausgaben 8.2p8, 8.3p5 und 8.4p2 geschlossen sein. --------------------------------------------- https://heise.de/-10187194 ∗∗∗ Cisco NX-OS Software Image Verification Bypass Vulnerability ∗∗∗ --------------------------------------------- A vulnerability in the bootloader of Cisco NX-OS Software could allow an unauthenticated attacker with physical access to an affected device, or an authenticated, local attacker with administrative credentials, to bypass NX-OS image signature verification.

===================== = End-of-Day report = ===================== Timeframe: Montag 02-12-2024 18:00 − Dienstag 03-12-2024 18:00 Handler: Michael Schlagenhaufer Co-Handler: n/a ===================== = News = ===================== ∗∗∗ Building Cyber Resilience Against Ransomware Attacks ∗∗∗ --------------------------------------------- This is the first blogpost in this series. Its aim is twofold: to enable organizations embarking on a journey to build resilience against ransomware to recognize common misconceptions hindering readiness efforts and offer a conceptual framework to guide effective resilience building. --------------------------------------------- https://blog.nviso.eu/2024/12/03/building-cyber-resilience-against-ransomwa… ∗∗∗ Unveiling RevC2 and Venom Loader ∗∗∗ --------------------------------------------- Venom Spider, also known as GOLDEN CHICKENS, is a threat actor known for offering Malware-as-a-Service (MaaS) tools like VenomLNK, TerraLoader, TerraStealer, and TerraCryptor. These tools have been utilized by other threat groups such as FIN6 and Cobalt in the past. Recently, Zscaler ThreatLabz uncovered two significant campaigns leveraging Venom Spider's MaaS tools between August and October 2024. During our investigation, we identified two new malware families, which we named RevC2 and Venom Loader, that were deployed using Venom Spider MaaS Tools. --------------------------------------------- https://www.zscaler.com/blogs/security-research/unveiling-revc2-and-venom-l… ∗∗∗ Gafgyt Malware Targeting Docker Remote API Servers ∗∗∗ --------------------------------------------- Our researchers identified threat actors exploiting misconfigured Docker servers to spread the Gafgyt malware.

When Android-based devices boot up, first the bootloader is verified to be running signed code, then the bootloader verifies the high-level operating system (HLOS). This blog post only covers the latter part. --------------------------------------------- https://www.nccgroup.com/us/research-blog/on-almost-signing-android-builds/ ∗∗∗ Extracting Files Embedded Inside Word Documents, (Tue, Dec 3rd) ∗∗∗ --------------------------------------------- I found a sample that is a Word document with an embedded executable.
