This detection rule identifies any changes made to the \"ExtErrorInformation\" registry key that indicate a disablement of ETW (Event Tracing for Windows) logging for the rpcrt4.dll. ETW is a crucial infrastructure for logging and tracking events in Windows, making it an important target for attackers attempting to avoid detection. The rule specifically looks for DWORD values of 0x00000000 or 0x00000002 being set on the targeted registry key, which signal a potential tampering with logging capabilities. The monitoring of this particular key is vital for maintaining the integrity of logging mechanisms, and any modifications can be indicative of malicious activities attempting to evade detection by manipulating system behaviors.
