===================== = End-of-Day report = ===================== Timeframe: Freitag 24-05-2024 18:00 − Montag 27-05-2024 18:00 Handler: Thomas Pribitzer Co-Handler: Michael Schlagenhaufer ===================== = News = ===================== ∗∗∗ Google-Security-Manager: Phishing-Tests bringen nichts und nerven Mitarbeiter ∗∗∗ --------------------------------------------- Mitarbeiter fühlten sich durch Phishing-Simulationen oftmals hintergangen, erklärt ein Security-Experte.

Doch warum pentesten wir überhaupt? --------------------------------------------- https://heise.de/-9718811 ∗∗∗ Checkpoint: Important Security Update – Enhance your VPN Security Posture! ∗∗∗ --------------------------------------------- Over the past few months, we have observed increased interest of malicious groups in leveraging remote-access VPN environments as an entry point and attack vector into enterprises. [..] By May 24, 2024 we identified a small number of login attempts using old VPN local-accounts relying on unrecommended password-only authentication method. [..] Password-only authentication is considered an unfavourable method to ensure the highest levels of security, and we recommend not to rely on this when logging-in to network infrastructure. Check Point has released a solution, as a preventative measure to address these unauthorised remote access attempts. --------------------------------------------- https://blog.checkpoint.com/security/enhance-your-vpn-security-posture/ ∗∗∗ Hackers phish finance orgs using trojanized Minesweeper clone ∗∗∗ --------------------------------------------- Hackers are utilizing code from a Python clone of Microsoft's venerable Minesweeper game to hide malicious scripts in attacks on European and US financial organizations. Ukraine's CSIRT-NBU and CERT-UA attribute the attacks to a threat actor tracked as 'UAC-0188,' who is using the legitimate code to hide Python scripts that download and install the SuperOps RMM. Superops RMM is a legitimate remote management software that gives remote actors direct access to the compromised systems. [..] The attack begins with an email sent from the address "support(a)patient-docs-mail.com," impersonating a medical center with the subject "Personal Web Archive of Medical Documents. --------------------------------------------- https://www.bleepingcomputer.com/news/security/hackers-phish-finance-orgs-u… ∗∗∗ Message board scams ∗∗∗ --------------------------------------------- Here’s how scams target buyers and sellers on online message boards, and how the gangs behind them operate.

[..] These malware-infected applications have collectively garnered over 5.5 million installs. [..] In this blog, we provide a technical analysis of Anatsa attack campaigns that leveraged themes like PDF readers and QR code readers to distribute malware in the Google Play store. --------------------------------------------- https://www.zscaler.com/blogs/security-research/technical-analysis-anatsa-c… ∗∗∗ Linguistic Lumberjack: Understanding CVE-2024-4323 in Fluent Bit ∗∗∗ --------------------------------------------- This vulnerability was discovered by the Tenable research team who described in their blog, that the flaw is due to improper validation of input names in requests, which can be exploited to cause memory corruption. This can result in denial-of-service attacks or information exposure, with remote code execution being possible under certain conditions.

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.

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.
