Apache Threading Error

Sigma Rules

View Source
Summary
This rule detects threading errors in Apache logs that could indicate an underlying issue that may be exploited for unauthorized access or lateral movement within a network. Specifically, it focuses on assertions related to thread priority changes, which are critical for maintaining stability in multi-threaded environments. When Apache logs report messages containing these assertions, it could signal a misconfiguration or potential attack vector. The rule is built around keywords drawn from common error messages found in Apache's error.log file and is particularly useful for monitoring active Apache services in server environments.
