This is the first time we will report on a NetSupport RAT intrusion, but malicious use of this tool dates back to at least 2016. During this report, we will analyze a case from January 2023 where a NetSupport RAT was utilized to infiltrate a network.

During a lengthy outage, I decided to redo some of my network configurations. As part of this change, I also reorganized my IPv6 setup, relying more on DHCPv6 and less on router advertisements to configure IPv6 addresses. Overall, this worked well. My Macs had no issues connecting to IPv6. However, the Linux host I use to alert me of network connectivity issues could not "ping" the test host via IPv6. --------------------------------------------- https://isc.sans.edu/diary/rss/30336 ∗∗∗ Tampered OpenCart Authentication Aids Credit Card Skimming Attack ∗∗∗ --------------------------------------------- Using out of date software is the leading cause of website compromise, so keeping your environment patched and up to date is one of the most important responsibilities of a website administrator. It’s not uncommon to employ the use of custom code on websites, and spend small fortunes on software developers to tailor their website just the way they want it. However, the usage of customised code can sometimes inadvertently lock a website administrator into using an out of date CMS installation long after its expiry date, particularly if they no longer have access to their old developer (or sufficient funds to hire a new one). --------------------------------------------- https://blog.sucuri.net/2023/10/tampered-opencart-authentication-aids-credi… ∗∗∗ Abusing gdb Features for Data Ingress & Egress ∗∗∗ --------------------------------------------- As of November 2019, elfutils supports debuginfod, a client/server protocol that enables debuggers (gdb) to fetch debugging symbols via HTTP/HTTPs from a user-specified remote server. This blog post will demonstrate how this feature of gdb can be abused to create data communication paths for data exfiltration and tool ingress. --------------------------------------------- https://www.archcloudlabs.com/projects/debuginfod/ ∗∗∗ Vorsicht vor Jobangeboten auf WhatsApp oder Telegram ∗∗∗ --------------------------------------------- Sie suchen gerade einen Job? Praktisch, wenn Sie gar nicht suchen müssen und Sie direkt auf WhatsApp oder Telegram einen Job angeboten bekommen. Dahinter stecken aber Kriminelle, die Ihnen z. B. einen „Datenoptimierungsjob mit möglichen Provisionen“ anbieten.

Our findings show that sensitive data about our customers and their projects or products have not been compromised. We immediately took steps to contain the incident. Forensic analysis conducted by an independent, third party indicates that no customer operations or Autodesk products were disrupted due to this incident. --------------------------------------------- https://www.autodesk.com/trust/security-advisories/adsk-sa-2023-0020 ∗∗∗ Kritische Sicherheitslücke in Cisco IOS XE - aktiv ausgenützt ∗∗∗ --------------------------------------------- Update: 23. Oktober 2023 Cisco hat für einige der von der Schwachstelle betroffenen Geräte Aktualisierungen veröffentlicht, und weitere Updates angekündigt. Das Unternehmen aktualisiert die Liste an verfügbaren Patches auf einer dedizierten Seite laufend. Wenn das Management-WebInterface eines Cisco XE Gerätes vor dem Einspielen des Updates offen im Netz erreichbar war, ist davon auszugehen, dass ein Angreifer dies ausgenutzt hat und zumindest neue Admin-Accounts angelegt hat. Damit ist die Installation von weiteren Hintertüren möglich, die - aus heutiger Sicht - nur mit einem Factory Reset / Neuinstallation von IOS XE umfassend entfernt werden können --------------------------------------------- https://cert.at/de/warnungen/2023/10/kritische-sicherheitslucke-in-cisco-io… ===================== = Vulnerabilities = ===================== ∗∗∗ Multiple Vulnerabilities in Cisco IOS XE Software Web UI Feature ∗∗∗ --------------------------------------------- Version 1.4: Updated the summary to indicate the first fixes are available.

A good example of these is the device class of ‘next generation’ firewalls, which usually include VPN termination functionality (meaning they’re Internet-accessible by network design).
