Detecting Stuxnet-Style Attacks

When to Use

• When implementing advanced threat detection for high-value OT targets (nuclear, chemical, critical infrastructure)
• When building detection for APT-style attacks targeting PLC logic and process manipulation
• When establishing PLC logic integrity monitoring to detect unauthorized modifications
• When investigating suspected process anomalies that may indicate cyber-physical attacks
• When designing defense-in-depth strategies against nation-state level OT threats

Do not use for basic OT intrusion detection (see detecting-attacks-on-scada-systems), for malware analysis of Stuxnet samples (see malware reverse engineering skills), or for PLC programming and logic development.

Prerequisites

• Detailed understanding of the Stuxnet attack chain and MITRE ATT&CK for ICS framework
• PLC logic backup repository with known-good baseline copies of all PLC programs
• Engineering workstation monitoring (EDR with OT awareness)
• Physics-based process models for the controlled physical process
• Network monitoring for industrial protocol traffic analysis
