HackTool - Impacket Tools Execution

Sigma Rules

View Source
Summary
This detection rule identifies the execution of various compiled Windows binaries related to the Impacket toolset, which is commonly used for network interactions and penetration testing. The rule looks for distinct patterns in the binary names, which could include exact matches or suffixes. Although effective in detecting potential misuse of these tools, it is important to note that legitimate use of Impacket by security professionals may result in false positives. The rule primarily scans process creation activities to flag instances where known Impacket binaries are executed, such as 'secretsdump', 'ntlmrelayx', and others. Given the potential for abuse in unauthorized network scenarios, the rule's severity is rated high, making it a critical component of defenses against execution of hacking tools within a Windows environment. Users are advised to monitor its outputs closely and correlate findings with additional context to mitigate false alerts.
