Loop Routines

Malicious processes often use loop routines to evade detection, resist termination, and maintain persistence on a compromised system. These techniques make it harder for security tools, administrators, or automated scripts to kill the malware.

Infinite Loop with Process Rebirth

The malware spawns a watchdog process that monitors and restarts the malicious process if killed.

while True:
    try:
        Run_Malicious_Code()
    except ProcessKilled:
        Launch_New_Instance()

Thread-Based Persistence

Instead of relying on a single process, the malware runs malicious code in multiple threads within a legitimate process (e.g., explorer.exe, svchost.exe).

while (true) {
    CreateThread(NULL, 0, MaliciousPayload, NULL, 0, NULL);
    Sleep(1000); // Spawns a new thread every second
}
