A phishing campaign impersonating Anthropic is reportedly bypassing several industry-leading secure email gateway (SEG) products, according to reporting by Dark Reading. The messages contain numerous obvious red flags typical of low-sophistication phishing, yet still reach user inboxes. The case highlights the limits of perimeter email filtering against brand-impersonation lures riding on the popularity of AI vendors. No specific indicators, malware or attribution were provided in the article.
