Timing Based Anti-Debug via RDTSC Check
This rule detects network traffic (specifically HTTP responses) that contains patterns indicative of timing-based anti-debugging techniques. It looks for the presence of "__rdtsc" (Read Time-Stamp Counter) and "ExitProcess" within the file data of an HTTP response, suggesting that a program might be attempting to detect a debugger by measuring execution time and exiting if debugging is detected. This is a common technique used by malware to evade analysis.
