Microsoft Teams to get AI protection against phishing and fraud

Microsoft is introducing an AI-powered security feature for Microsoft Teams designed to detect phishing, scams, and identity theft, according to reports from Bleeping Computer. Unlike previous security measures that primarily focused on identifying malicious links and files, this new tool will analyze conversations to identify suspicious behavior in messages themselves. Microsoft states the feature will be primarily utilized for interactions with new contacts, given their heightened security risk.

The announcement comes in the wake of earlier warnings from Microsoft about attackers impersonating help desk staff within Teams to deceive users into granting them remote access. In a Microsoft 365 Message Center post, Microsoft explained that during initial validation, the detection may operate in the background without alerting users. Post-validation, users may receive a warning if potential phishing is detected.

Microsoft assures that no messages will be stored or utilized for training AI models. The tool will solely serve security purposes and not for surveillance or advertising. The rollout of this feature is set to commence in early November 2026, with general availability expected by the first half of December. Users will not need to configure the feature; it will be automatically enabled by default.
