Code Red is not ICS specific malware; it was a famous worm that targeted computers running
Microsoft's IIS web server. Unlike Flame, Havex, and Stuxnet, which were specifically designed to
target industrial control systems or perform espionage related to ICS environments, Code Red was
aimed at exploiting vulnerabilities in internet-facing software to perform denial-of-service attacks
and other malicious activities.
