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.

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.

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).
