AI Incident Database: Microsoft Reportedly Blocks 1.6 Million Bot Signup Attempts Per Hour Amid Global AI-Driven Fraud Surge

Between April 2024 and April 2025, Microsoft reportedly blocked 1.6 million bot signups per hour and disrupted $4 billion in fraud attempts linked to AI-enhanced scams. The company's Cyber Signals report details how generative AI is being used to fabricate realistic e-commerce sites, job offers, customer service bots, and phishing lures. Fraud actors now automate mass-deceptive campaigns with fake reviews, deepfakes, and cloned brand domains at unprecedented scale and speed.
