===================== = End-of-Day report = ===================== Timeframe: Donnerstag 07-08-2025 18:00 − Freitag 08-08-2025 18:00 Handler: Guenes Holler Co-Handler: Felician Fuchs ===================== = News = ===================== ∗∗∗ New EDR killer tool used by eight different ransomware groups ∗∗∗ --------------------------------------------- A new Endpoint Detection and Response (EDR) killer that is considered to be the evolution of 'EDRKillShifter,' developed by RansomHub, has been observed in attacks by eight different ransomware gangs. Such tools help ransomware operators turn off security products on breached systems so they can deploy payloads, escalate privileges, attempt lateral movement, and ultimately encrypt devices on the network without being detected. --------------------------------------------- https://www.bleepingcomputer.com/news/security/new-edr-killer-tool-used-by-… ∗∗∗ Why blow up satellites when you can just hack them? ∗∗∗ --------------------------------------------- Four countries have now tested anti-satellite missiles (the US, China, Russia, and India), but it's much easier and cheaper just to hack them. In a briefing at the Black Hat conference in Las Vegas, Milenko Starcik and Andrzej Olchawa from German biz VisionSpace Technologies demonstrated how easy it is by exploiting software vulnerabilities in the software used in the satellites themselves, as well as the ground stations that control them. --------------------------------------------- https://go.theregister.com/feed/www.theregister.com/2025/08/07/balck_hat_sa… ∗∗∗ US confirms takedown of BlackSuit ransomware gang that racked up $370 million in ransoms ∗∗∗ --------------------------------------------- U.S. law enforcement agencies provided new details on an operation that dismantled critical infrastructure used by the BlackSuit ransomware gang after the organization’s leak site was replaced with a takedown banner nearly two weeks ago. The group — which rebranded from its Royal name after a devastating 2023 attack that shut down the city of Dallas — successfully attacked more than 450 entities in the U.S. Since emerging in 2022, the gang secured more than $370 million in ransom payments, according to U.S. investigators. --------------------------------------------- https://therecord.media/us-confirms-blacksuit-takedown ∗∗∗ Abusing Ubuntu 24.04 features for root privilege escalation ∗∗∗ --------------------------------------------- With the recent release of Ubuntu 24.04, we at Snyk Security Labs thought it would be interesting to examine the latest version of this Linux distribution to see if we could find any interesting privilege escalation vulnerabilities. In this post, we have seen that it only takes the leveraging of one small vulnerability, combined with a number of features, to achieve a chain of exploitation resulting in a full privilege escalation. Even where security controls are in place preventing the direct exploitation of a small vulnerability it may still be possible to finesse limited exploitation potential into a much greater impact. --------------------------------------------- https://labs.snyk.io/resources/abusing-ubuntu-root-privilege-escalation/ ∗∗∗ Oops Safari, I think You Spilled Something ∗∗∗ --------------------------------------------- In February 2023, researchers at Exodus Intelligence discovered a bug in the Data Flow Graph (DFG) compiler of WebKit, the browser engine used by Safari. This bug, CVE-2024-44308, was patched by Apple in November 2024. While it was alive, its exploit was chained with PAC and APRR bypasses on Apple Silicon to yield renderer remote code execution capabilities on macOS and iOS. Such capabilities, and many others including LPEs and RCEs on Windows and Linux, are available to Exodus’ customers. --------------------------------------------- https://blog.exodusintel.com/2025/08/04/oops-safari-i-think-you-spilled-som… ∗∗∗ 60 Malicious Ruby Gems Used in Targeted Credential Theft Campaign ∗∗∗ --------------------------------------------- Socket’s Threat Research Team has uncovered a long-running supply chain attack in the RubyGems ecosystem. Since at least March 2023, a threat actor using the aliases zon, nowon, kwonsoonje, and soonje has published 60 malicious gems posing as automation tools for Instagram, Twitter/X, TikTok, WordPress, Telegram, Kakao, and Naver. These gems deliver their advertised functionality, such as bulk posting or engagement, but covertly exfiltrate credentials (usernames and passwords) to threat actor-controlled infrastructure, which classifies them as infostealer malware. --------------------------------------------- https://socket.dev/blog/60-malicious-ruby-gems-used-in-targeted-credential-… ===================== = Vulnerabilities = ===================== ∗∗∗ Security updates for Friday ∗∗∗ --------------------------------------------- Security updates have been issued by AlmaLinux (gdk-pixbuf2, glibc, kernel, kernel-rt, libxml2, and opentelemetry-collector), Fedora (firefox, mingw-opencv, moby-engine, varnish, webkitgtk, xen, and yarnpkg), Oracle (firefox, gdk-pixbuf2, glibc, kernel, libblockdev, libxml2, python-requests, python3.12-setuptools, and qt5-qt3d), Red Hat (libxml2, pcs, and sudo), and SUSE (agama, chromium, dpkg, ghostscript, iperf, kubo, libIex-3_3-32, libpoppler-cpp2, libsoup, libtiff-devel-32bit, nginx, python-urllib3, ruby2.5, tgt, traefik, and traefik2). --------------------------------------------- https://lwn.net/Articles/1033009/ ∗∗∗ CISA Issues ED 25-02: Mitigate Microsoft Exchange Vulnerability ∗∗∗ --------------------------------------------- Today, CISA issued Emergency Directive (ED) 25-02: Mitigate Microsoft Exchange Vulnerability in response to CVE-2025-53786, a vulnerability in Microsoft Exchange server hybrid deployments. ED 25-02 directs all Federal Civilian Executive Branch (FCEB) agencies with Microsoft Exchange hybrid environments to implement required mitigations by 9:00 AM EDT on Monday, August 11, 2025. This vulnerability presents significant risk to all organizations operating Microsoft Exchange hybrid-joined configurations that have not yet implemented the April 2025 patch guidance. --------------------------------------------- https://www.cisa.gov/news-events/alerts/2025/08/07/cisa-issues-ed-25-02-mit… ∗∗∗ CISA Releases Ten Industrial Control Systems Advisories ∗∗∗ --------------------------------------------- https://www.cisa.gov/news-events/alerts/2025/08/07/cisa-releases-ten-indust… -- CERT.at Daily mailing list Listinfo: https://lists.cert.at/cgi-bin/mailman/listinfo/daily
