Would Your Employees Join a Fake Anthropic AI Preview?

Executive summary: This Cofense Intelligence report describes an active credential-phishing campaign (Anthropic AI preview lure) that leverages legitimate services (GoTo Webinar, Zapier URL shortener), multiple CAPTCHAs (Cloudflare and custom sliding CAPTCHA) and deceptive subdomains to bypass email security and automated analysis; victims who complete the flow encounter convincing fake Google or Microsoft login pages that exfiltrate credentials (Microsoft pages capture both username and password, Google page currently captures usernames). The report provides the campaign timeline, screenshots, IOCs (malicious URLs and ATR references), and mitigations to detect and reduce risk.
