ruletype: Sigma

description: Detects suspicious uses of the SysInternals Procdump utility by using
|
|
a special command line parameter in combination with the lsass.exe process. This
|
|
way we're also able to catch cases in which the attacker has renamed the procdump
|
|
executable.
|
|
detection:
|
|
SELECTION_1:
|
|
EventID: 1
|
|
SELECTION_2:
|
|
CommandLine: '* -ma *'
|
|
SELECTION_3:
|
|
CommandLine: '* lsass*'
|
|
SELECTION_4:
|
|
CommandLine: '* ls*'
|
|
condition: (SELECTION_1 and SELECTION_2 and (SELECTION_3 or SELECTION_4))
|
|
falsepositives:
|
|
- Unlikely, because no one should dump an lsass process memory
|
|
- Another tool that uses the command line switches of Procdump
