Detection & IOCsextracted from sources · hover to see the quote
- →CVE-2022-41076 exploitation involves escaping a PowerShell Remoting Session Configuration to run unapproved commands on the target system — monitor for PowerShell remoting sessions that execute commands outside of configured session constraints. ↗
- →Exploitation requires authenticated (low-privilege) access and additional attacker preparation steps before the exploit fires — look for social engineering precursors such as MalDocs or LNK files delivering the initial foothold. ↗
- →Attack complexity is high because the attacker must prepare the target environment prior to exploitation — correlate anomalous PowerShell remoting configuration changes with subsequent remote session activity. ↗
- →Any authenticated (non-admin) user can trigger this vulnerability — alert on low-privilege accounts initiating PowerShell Remoting sessions, especially where session configuration constraints are subsequently bypassed. ↗
- ·Microsoft rates exploitation as 'More Likely' but confirms the vulnerability had not been publicly disclosed or actively exploited at time of patch release — prioritise patching but no in-the-wild IOCs are available. ↗
- ·The exact preparatory actions an attacker must take before exploitation are not publicly documented by Microsoft, limiting the ability to build precise pre-exploitation detection rules. ↗

[HIGH] Microsoft Patch Tuesday, December 2022 Edition
Microsoft has released its final monthly batch of security updates for 2022, fixing more than four dozen security holes in its various Windows operating systems and related software. The most pressing patches include a zero-day in a Windows feature that tries to flag malicious files from the Web, a critical bug in PowerShell , and a dangerous flaw in Windows 11 systems that was detailed publicly prior to this week’s Patch Tuesday.
The security updates include patches for Azure , Microsoft Edge, Office , SharePoint Server , SysInternals , and the .NET framework .
