Summary
The rule "RemCom Service File Creation" is designed to detect the creation of the RemCom service executable file, indicated by the filename ending with "\RemComSvc.exe". This detection rule highlights the risk of unauthorized access or remote control of systems through the execution of the RemCom tool, a known utility that allows remote management of Windows machines. When the specified executable is created, it serves as a potential indicator of malicious activity related to remote executions, consistent with techniques outlined in the MITRE ATT&CK framework such as T1569.002 (Service Execution). The rule is currently in a testing phase and has a medium severity level, suggesting that alerts triggered by this rule should be investigated for potential threats. The rule is authored by Nasreddine Bencherchali of Nextron Systems and has references to a GitHub repository for further details about the RemCom tool. Given its nature, the rule carries a risk of false positives as the detection of the file creation alone does not definitively indicate malicious activity. The detection relies solely on the target filename, and users should be aware of the context in which this executable is created before concluding on any malicious intent.
