   Microsoft Teams Adds AI Phishing Detection

   Microsoft Teams is rolling out a new artificial intelligence capability designed to detect phishing and scam attacks directly within conversation content. The feature uses context-aware technology to spot threats such as IT-support impersonation schemes, which often rely on social engineering rather than traditional malicious links or file attachments. Security researchers and platforms have increasingly highlighted how threat actors abuse Microsoft Teams external chat and conversation features for initial access and credential harvesting.

   Why it matters

   Phishing tactics have evolved beyond standard email links, prompting enterprise platforms to build native defenses against conversational engineering. Microsoft is layering AI tools to evaluate live dialogue in real time across its communication software. This update complements broader security adjustments across the application, including third-party deepfake scanning tools slated for November.

   What is confirmed

   • Microsoft Teams is getting an AI-powered, context-aware phishing detection feature.
   • The AI tool reads conversation content in real time to catch attacks with no malicious links or files, such as IT-support impersonation.
   • Microsoft Teams will also allow third-party tools to scan meetings for deepfakes starting in November.

   What to watch next

   • Deployment dates for the AI phishing detection feature across enterprise tiers
   • Performance metrics on how effectively the tool catches linkless social engineering attacks
