HackTool - RemoteKrbRelay Execution

Sigma Rules

View Source
Summary
The rule titled "HackTool - RemoteKrbRelay Execution" is designed to detect the execution of a malicious tool known as RemoteKrbRelay. This tool facilitates Kerberos relaying attacks, which can compromise the confidentiality and integrity of authentication processes in Windows environments. The detection focuses primarily on identifying the use of the tool through specific command line flags that are typically employed during its execution, as well as its executable file attributes. The rule encompasses various command line patterns that indicate potential misuse, such as options for targeting systems and modifying user credentials. By monitoring process creation events, the rule aims to alert security analysts to the presence of this potentially malicious activity, thereby enhancing the overall security posture against credential access attacks. The detection logic combines image path checks and obliges the presence of certain command line parameters indicative of the tool's functionalities. Its implementation may be crucial for organizations utilizing Kerberos authentication in their infrastructure to counteract sophisticated attack vectors.
