As detailed in its latest Cyber Signals report, Microsoft announced it thwarted over $4 billion in fraud attempts from April 2024 to April 2025. Announcing its cybersecurity milestone, the company also issues a warning for AI-enhanced fraud schemes. Few scams that use gen-AI include deepfake job interviews, fake e-commerce sites, impersonation scams, and more.

Microsoft highlighted a troubling rise in tech support scams, including attacks by the cybercriminal group Storm-1811. The attack exploited Windows’ Quick Assist tool to gain unauthorized device access. In response, Microsoft strengthened safeguards, now blocking over 4,400 suspicious Quick Assist connections daily.
