Windows Odbcconf Load Response File
Description
The following analytic identifies the odbcconf.exe, Windows Open Database Connectivity utility, loading up a resource file. The file extension is arbitrary and may be named anything. The resource file itself may have different commands supported by Odbcconf to load up a DLL (REGSVR) on disk or additional commands. During triage, review file modifications and parallel processes.

Macros
The SPL above uses the following Macros:
windows_odbcconf_load_response_file_filter is a empty macro by default. It allows the user to filter out any results (false positives) without editing the SPL.
Required fields
List of fields required to use this analytic.
- process.pid
- process.file.path
- process.file.name
- process.cmd_line
- actor.user.name
- actor.process.pid
- actor.process.file.path
- actor.process.file.name
- device.hostname
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.
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 | $process_name$ has been identified on $dest_device_id$ under user $dest_user_id$ 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.
