Windows Odbcconf Load DLL
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.

Macros
The SPL above uses the following Macros:
windows_odbcconf_load_dll_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.

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.
Associated Analytic Story
RBA
Risk Score | Impact | Confidence | Message |
---|---|---|---|
42.0 | 60 | 70 | An instance of $parent_process_name$ spawning $process_name$ was identified on endpoint $dest$ by user $user$ attempting to circumvent controls. |
The Risk Score is calculated by the following formula: Risk Score = (Impact * Confidence/100). Initial Confidence and Impact is set by the analytic author.
