The rule focuses on identifying the execution of HollowReaper, a tool used in process hollowing techniques notorious for stealthy payload deployments. HollowReaper functions by overwriting the memory space of a legitimate process with manipulated shellcode that can execute malicious payloads while maintaining the appearance of trusted system binaries. This creates a significant risk as it can allow malware to operate undetected by standard security measures. The detection is specifically targeted at instances where the HollowReaper executable, 'HollowReaper.exe', is launched. The implications of this detection rule are critical for organizations that need to maintain system integrity and prevent advanced threats that utilize process hollowing as a means to bypass traditional security defenses.
