Angreifer können über IPv6-Pakete einen Host kompromittieren und dort Code ausführen. Weben der Bewertung mit dem CVEv3 Score 9.8 (critical, "Exploitation More Likely") empfiehlt Redmond Administratoren momentan IPv6 zu deaktivieren, hat aber auch Sicherheitsupdates für Windows bereitgestellt.

The creator of Styx Stealer revealed his personal details, including Telegram accounts, emails, and contacts, by debugging the stealer on his own computer with a Telegram bot token provided by a customer involved in the Agent Tesla campaign. This critical OpSec failure not only compromised his anonymity but also provided valuable intelligence about other cybercriminals, including the originator of the Agent Tesla campaign. --------------------------------------------- https://research.checkpoint.com/2024/unmasking-styx-stealer-how-a-hackers-s… ∗∗∗ "WireServing" Up Credentials: Escalating Privileges in Azure Kubernetes Services ∗∗∗ --------------------------------------------- Mandiant disclosed this vulnerability to Microsoft via the MSRC vulnerability disclosure program, and Microsoft has fixed the underlying issue. [..] Adopting a process to create restrictive NetworkPolicies that allow access only to required services prevents this entire attack class.
