Patch Tuesday -- Exploit Wednesday: Pwning Windows Ancillary Function Driver for WinSock (afd.sys) in 24 Hours - #CVE-2023-21768
2023-03-22 _Verify that your Windows Ancillary Function Driver for Winsock (afd.sys) is up-to-date and matches the versions mentioned in the blog post to determine if you are vulnerable to this exploit. To mitigate this issue, ensure that all security patches released by Microsoft are applied promptly and that your system is running the latest version of afd.sys. Additionally, consider implementing additional security measures such as firewalls and antivirus software, using signatures or heuristics to detect malicious software, enforcing binary and application integrity with digital signature verification to prevent untrusted code from executing, using capabilities to prevent suspicious behavior patterns from occurring on endpoint systems (such as suspicious process, file, API call etc.), and removing or denying access to unnecessary and potentially vulnerable software. --Darien Kindlund_ [View Article](https://securityintelligence.com/posts/patch-tuesday-exploit-wednesday-pwning-windows-ancillary-function-driver-winsock/)
