===================== = End-of-Day report = ===================== Timeframe: Montag 27-09-2021 18:00 − Dienstag 28-09-2021 18:00 Handler: Dimitri Robl Co-Handler: Robert Waldner ===================== = News = ===================== ∗∗∗ FoggyWeb: Targeted NOBELIUM malware leads to persistent backdoor ∗∗∗ --------------------------------------------- In-depth analysis of newly detected NOBELIUM malware: a post-exploitation backdoor that Microsoft Threat Intelligence Center (MSTIC) refers to as FoggyWeb. NOBELIUM uses FoggyWeb to remotely exfiltrate the configuration database of compromised AD FS servers, decrypted token-signing certificate, and token-decryption certificate, as well as to download and execute additional components. --------------------------------------------- https://www.microsoft.com/security/blog/2021/09/27/foggyweb-targeted-nobeli… ∗∗∗ TLS 1.3 and SSL - the current state of affairs, (Tue, Sep 28th) ∗∗∗ --------------------------------------------- It has been over 3 years since the specification for TLS 1.3 was published, and although the protocol has some minor drawbacks, it is undoubtedly the most secure TLS version so far. One would therefore hope that the adoption of TLS 1.3 and its use on web servers around the globe would steadily increase over time (ideally hand in hand with a slow disappearance of older cryptographic protocols, especially the historic SSL 2.0 and SSL 3.0). --------------------------------------------- https://isc.sans.edu/diary/rss/27882 ∗∗∗ Securing mobile devices. A timely reminder ∗∗∗ --------------------------------------------- If you’re commuting again or if you’re responsible for securing your people’s devices it’s a good idea to revisit and review your security admin for mobile devices. This post isn’t breaking any new ground, but it is a good place to start that review process, and think about your security behaviours. --------------------------------------------- https://www.pentestpartners.com/security-blog/securing-mobile-devices-a-tim… ∗∗∗ Vorsicht, wenn die Wohnungsbesichtigung über booking.com abgewickelt werden sollte ∗∗∗ --------------------------------------------- Sie haben endlich Ihre Traumwohnung gefunden? Der einzige Haken: Sie sollten schon vor der Besichtigung eine Kaution bezahlen, die angeblich von booking.com verwaltet wird? Dann sind Sie auf ein betrügerisches Wohnungsinserat gestoßen.

We also provide actionable recommendations any organization can adopt immediately to begin protecting their software supply chains in the cloud. --------------------------------------------- https://unit42.paloaltonetworks.com/cloud-threat-report-2h-2021/ ∗∗∗ Anatomy and Disruption of Metasploit Shellcode ∗∗∗ --------------------------------------------- In April 2021 we went through the anatomy of a Cobalt Strike stager and how some of its signature evasion techniques ended up being ineffective against detection technologies. In this blog post we will go one level deeper and focus on Metasploit, an often-used framework interoperable with Cobalt Strike. --------------------------------------------- https://blog.nviso.eu/2021/09/02/anatomy-and-disruption-of-metasploit-shell… ===================== = Vulnerabilities = ===================== ∗∗∗ ZDI-21-1116: NETGEAR R7800 net-cgi Out-Of-Bounds Write Remote Code Execution Vulnerability ∗∗∗ --------------------------------------------- This vulnerability allows network-adjacent attackers to execute arbitrary code on affected installations of NETGEAR R7800 routers. Authentication is not required to exploit this vulnerability.
