Tenable warns attackers are weaponizing AI coding assistant config files for silent persistence.
Tenable reports that attackers are targeting AI coding assistant configuration files as a persistence mechanism.
By injecting malicious hooks into agent settings, adversaries can execute code automatically whenever the developer agent runs.
Tenable says the attack surface has moved from the registry into the agent harness, enabling silent malware persistence across developer repositories. The post details how these developer-agent harness attacks work and how to defend against them.
