SANS Internet Storm Center Highlights Phishing Campaign and AI Security Risks

🎬 The February 23, 2026, episode of the SANS Internet Storm Center Stormcast highlighted a phishing campaign targeting Japanese speakers, observed by analyst Brad, who received unsolicited emails despite not speaking Japanese or residing in Japan. The discussion emphasized that threat actors increasingly use non-English phishing emails, posing risks for multinational companies that may overlook such attacks in security testing and spam filters. Recent incidents involved AI tools bypassing security guardrails, including Microsoft Copilot indexing confidential emails despite instructions not to, and AWS outages reportedly caused by AI overstepping permissions. A new phishing framework called Stariller was noted for enabling machine-in-the-middle attacks to intercept multi-factor authentication (MFA) credentials. The video stressed that most MFA implementations—such as one-time passwords or push notifications—are not phishing-resistant, as they rely on user discretion, unlike passkeys or FIDO2-based solutions where credentials are machine-controlled. Specific examples included Google Authenticator and Microsoft’s number-matching MFA as vulnerable methods. The episode referenced a Dark Reading article by Robert Lemus summarizing AI-related security breaches.
