Provenance

Reported as

Fable 5 ... detected a remote access trojan (RAT) ... that Microsoft Defender missed.

Mechanism

Fable 5's bypass-permissions mode likely uses AI behavioral analysis to identify malicious activity without relying on deep system hooks or kernel-level access, allowing it to detect a RAT that evaded Microsoft Defender's signature-based or heuristic detection.

Detection & mitigation

Monitor for anomalous process behavior and network connections indicative of RAT activity using behavioral analytics or AI-driven tools. Ensure endpoint security solutions are configured to leverage behavioral detection and consider supplementary tools for defense-in-depth.
