This rule detects the presence of anti-debugging techniques within HTTP payload data. Specifically, it looks for the strings "IsDebuggerPresent" and "ExitProcess" (case-insensitive) in the HTTP response body. The combination of these strings suggests that a malicious payload might be checking for a debugger and attempting to terminate if one is detected, a common defense evasion technique used by malware.
