LSASS Process Dump File in CrashDumps Folder
This rule detects the creation of a file named 'lsass.exe.dmp' within the 'C:\Windows\System32\config\systemprofile\AppData\Local\CrashDumps\' directory. This specific file pattern and location are indicative of an attempt to dump the LSASS process memory, which often contains sensitive credential material. Adversaries frequently use this technique to extract credentials for lateral movement or persistence. The rule specifically references the 'LSASS Shtinkering' technique, which abuses Windows Error Reporting to achieve LSASS memory dumping.
