HackTool - SharpLDAPmonitor Execution

Sigma Rules

View Source
Summary
The detection rule identifies the execution of the SharpLDAPmonitor tool, which is designed to facilitate monitoring of LDAP (Lightweight Directory Access Protocol) servers. This tool can track the creation, deletion, and modification of LDAP objects, making it a potential vector for unwanted monitoring, usually associated with reconnaissance or enumeration activities in a networked environment. The rule incorporates both process creation logs and command line argument analysis to discern malicious activity signified by specific characteristics associated with SharpLDAPmonitor.exe. The detection logic is based on two selections: one checks for the filename or path ending with 'SharpLDAPmonitor.exe', while the second inspects the command line arguments for the presence of '/user:', '/pass:', or '/dcip:', indicative of LDAP connection parameters. The condition allows detection if any one of these criteria matches. Additionally, as part of incident response and triage practices, false positives may arise from configurations or legitimate uses of the SharpLDAPmonitor within approved security operations, necessitating careful analysis.
