PowerShell ShellCode
Sigma
Detects Base64 encoded Shellcode
Detects usage of certain functions and keywords that are used to manipulate security descriptors in order to potentially set a backdoor. As seen used in the DAMP project.
Detects usage of known powershell cmdlets such as "Clear-EventLog" to clear the Windows event logs
Detects execution of "TroubleshootingPack" cmdlets to leverage CVE-2022-30190 or action similar to "msdt" lolbin (as described in LOLBAS)
Detects when when a mounted share is removed. Adversaries may remove share connections that are no longer useful in order to clean up traces of their operation
Detects usage of the "Write-EventLog" cmdlet with 'RawData' flag. The cmdlet can be levreage to write malicious payloads to the EventLog and then retrieve them later for later use
Detects usage of the "Set-Service" powershell cmdlet to configure a new SecurityDescriptor that allows a service to be hidden from other utilities such as "sc.exe", "Get-Service"...etc. (Works only in powershell 7)
Detects usage of the WMI class "Win32_NTEventlogFile" in a potentially suspicious way (delete, backup, change permissions, etc.) from a PowerShell script
Detects when a user disables the Windows Firewall via a Profile to help evade defense.
