name: MS Scripting Process Loading Ldap Module

type: Anomaly
|
|
description: The following analytic detects the execution of MS scripting processes
|
|
(wscript.exe or cscript.exe) loading LDAP-related modules (Wldap32.dll, adsldp.dll,
|
|
adsldpc.dll). It leverages Sysmon EventCode 7 to identify these specific DLL loads.
|
|
This activity is significant as it may indicate an attempt to query LDAP for host
|
|
information, a behavior observed in FIN7 implants. If confirmed malicious, this
|
|
could allow attackers to gather detailed Active Directory information, potentially
|
|
leading to further exploitation or data exfiltration.
|
|
data_source:
|
|
- Sysmon EventID 7
|
|
search: '`sysmon` EventCode =7 Image IN ("*\\wscript.exe", "*\\cscript.exe") ImageLoaded
|
|
IN ("*\\Wldap32.dll", "*\\adsldp.dll", "*\\adsldpc.dll") | stats min(_time) as firstTime
|
|
max(_time) as lastTime count by Image EventCode process_name ProcessId ProcessGuid
|
|
Computer ImageLoaded | rename Computer as dest | `security_content_ctime(firstTime)`
|
|
| `security_content_ctime(lastTime)` | `ms_scripting_process_loading_ldap_module_filter`'
|
|
how_to_implement: To successfully implement this search, you need to be ingesting
|
|
logs with the process name, parent process, and command-line executions from your
|
|
endpoints. If you are using Sysmon, you must have at least version 6.0.4 of the
|
|
Sysmon TA. Tune and filter known instances where renamed rundll32.exe may be used.
|
|
known_false_positives: automation scripting language may used by network operator
|
|
to do ldap query.
