description: The following analytic identifies odbcconf.exe, Windows Open Database
Connectivity utility, utilizing the action function of regsvr to load a DLL. An
example will look like - odbcconf.exe /A { REGSVR T1218-2.dll }. During triage,
review parent process, parallel procesess and file modifications.
data_source:
- Sysmon Event ID 1
search:
selection1:
CommandLine:
- '*/a *'
- '*-a*'
Image|endswith: odbcconf.exe
selection2:
CommandLine: '*regsvr*'
condition: selection1 and selection2
how_to_implement: To successfully implement this search you need to be ingesting information
on process that include the name of the process responsible for the changes from
your endpoints into the `Endpoint` datamodel in the `Processes` node. In addition,
confirm the latest CIM App 4.20 or higher is installed and the latest TA for the
endpoint product.
known_false_positives: False positives may be present and filtering may need to occur
based on legitimate application usage. Filter as needed.
