Description

The following analytic detects the execution of the Apache Benchmark binary (ab.exe), commonly used by MetaSploit payloads. It leverages data from Endpoint Detection and Response (EDR) agents, focusing on process creation events where the original file name is ab.exe. This activity is significant as it may indicate the presence of a MetaSploit attack, which uses Apache Benchmark to generate malicious payloads. If confirmed malicious, this could lead to unauthorized network connections, further system compromise, and potential data exfiltration. Immediate investigation is required to determine the intent and scope of the activity.

  • False positives should be limited as there is a small subset of binaries that contain the original file name of ab.exe. Filter as needed.
