status: production
|
|
type: TTP
|
|
description: The following analytic identifies a suspicious remote thread execution
|
|
in some process being abused by threat actor and malware like qakbot. Qakbot is
|
|
one of the malware using this technique to load its malicious dll module or malicious
|
|
code in the targeted host. This TTP can be a good pivot to verify what is the behavior
|
|
of the targeted Image process after this detection trigger. look for network connection,
|
|
child process execution, file access and many more that helps to verify the indication
|
|
of malware infection.
|
|
data_source:
|
|
- Sysmon Event ID 8
|
|
search: '`sysmon` EventCode=8 TargetImage IN ("*\\Taskmgr.exe", "*\\calc.exe", "*\\notepad.exe",
|
|
"*\\rdpclip.exe", "*\\explorer.exe", "*\\wermgr.exe", "*\\ping.exe", "*\\OneDriveSetup.exe",
|
|
"*\\dxdiag.exe", "*\\mobsync.exe", "*\\msra.exe", "*\\xwizard.exe","*\\cmd.exe", "*\\powershell.exe") | stats count
|
|
min(_time) as firstTime max(_time) as lastTime by TargetImage TargetProcessId SourceProcessId EventCode
|
|
StartAddress SourceImage dest | `security_content_ctime(firstTime)` | `security_content_ctime(lastTime)`
|
|
| `windows_process_injection_remote_thread_filter`'
|
|
how_to_implement: To successfully implement this search, you must be ingesting data
|
|
that records process activity from your hosts like remote thread EventCode=8 of
|
|
sysmon. If you are using Sysmon, you must have at least version 6.0.4 of the Sysmon
|
|
TA.
