Detects execution of "odbcconf" with "REGSVR" in order to register a new DLL (equivalent to running regsvr32). Attackers abuse this to install and run malicious DLLs.

selection_img:
    - Image|endswith: '\odbcconf.exe'
    - OriginalFileName: 'odbcconf.exe'
selection_cli:
    # Note: The "/A" flag is not required to call a specific action
    CommandLine|contains|all:
        - 'REGSVR '
        - '.dll'
condition: all of selection_*

False positives (as the rule lists them)

• Legitimate DLLs being registered via "odbcconf" will generate false positives. Investigate the path of the DLL and its content to determine if the action is authorized.
