A new Microsoft Exchange flaw is being exploited by attackers to deliver remote access tools and remote administration software. Researchers from CrowdStrike discovered the exploit chain while investigating a Play ransomware attack. The exploit chain bypasses mitigations for a URL rewrite flaw, allowing the attackers to gain remote code execution privileges on target endpoints. A patch is available to fix the flaw. It is recommended that organizations with on-prem Microsoft Exchange servers apply the November 2022 cumulative update or disable OWA if they cannot apply the patch. Microsoft has been deploying various solutions to keep its customers secure on Exchange servers, and by next month, it will permanently disable Exchange Online's basic authentication and replace it with a modernized authentication method.

A Russian hacker group called KillNet has claimed to have hacked an FBI database. Since the war between Russia and Ukraine began in February, Killnet has launched 76 attacks against countries supporting Ukraine. Recently, the hacker group claimed to have stolen the personal information of over 10,000 US federal agents. This hack is similar to previous attacks by KillNet, which have had political undertones. It is not yet clear whether this claim by KillNet is true or not.
