AI-Driven Phishing and BEC Threats Surge as Cybercriminals Weaponize Generative AI, Mimecast Warns
A new Mimecast report finds that cybercriminals are increasingly leveraging generative artificial intelligence to create more convincing phishing, business email compromise (BEC) and multichannel deception campaigns. Phishing now accounts for 77% of attacks, while ClickFix threats have risen fivefold and represent roughly 8% of incidents in the first half of 2025. The report highlights abuse of trusted tools such as DocuSign and Salesforce, and cites the Scattered Spider group as linked to over 900,000 detections. Mimecast recommends multi‑factor authentication, advanced email defenses with anomaly detection, and layered security training to counter the rising AI‑powered threat landscape.
