Microsoft's New AI Security Tool Can Spot Malware Early - and Even Reverse Engineer It to Crack the Code

MICROSOFT, AUG 5 – Project Ire autonomously reverse engineers malware with 90% accuracy and a 2% false positive rate, aiming to assist human researchers and enhance threat detection in Microsoft Defender.

  • On Tuesday, Microsoft announced Project Ire, prototype AI for autonomous malware detection via reverse engineering of software files.
  • Amid evolving attack techniques, Project Ire uses autonomous reverse engineering and large language models to help the IT security sector leverage AI against concealed threats.
  • In tests involving nearly 4,000 files, Project Ire correctly flagged roughly a quarter of malware and identified 90% of files in a Windows driver dataset, with only 2% false positives.
  • Microsoft will integrate Project Ire into Microsoft Defender as a binary analyzer, which already produced an automatic blocking decision against malware tied to an elite hacking group.
  • Looking ahead, the team plans to scale Ire’s speed and accuracy for first-encounter classification, emphasizing its role in assisting overburdened human analysts amid rising AI adoption in cybersecurity.
