  • •AI-assisted exploit development for PLCs shows potential but requires human guidance.
  • •The experiment targeted CVE-2021-31886, a critical vulnerability in WAGO PLCs.
  • •The use of AI could lower barriers for attackers, increasing risks to critical infrastructure.

Researchers at Forescout’s Vedere Labs successfully used AI to port a remote code execution (RCE) exploit from the WAGO 750-852 PLC to the WAGO 750-831 PLC, targeting CVE-2021-31886. The experiment required significant human oversight, taking over eight hours and costing approximately $535 in API usage. The AI confirmed the vulnerability through live probing and static analysis, but initial attempts to create a functional exploit faced challenges, leading to a switch in AI models. Once operational, the AI produced multiple payloads quickly, but an attempt to enhance the exploit resulted in bricking the PLC. The findings highlight the potential for AI to automate parts of the exploit development process, raising alarms about the accessibility of such attacks against critical infrastructure. The experiment follows recent attacks on PLCs in the water sector, emphasizing the urgency of addressing these vulnerabilities.
