New MatrixPDF Phishing Technique Targets Gmail Users

📄 Researchers at Varonis have identified a sophisticated phishing toolkit called MatrixPDF that embeds prompts, JavaScript, and external redirects inside seemingly legitimate PDF files to target Gmail users. Attackers exploit Gmail's preview and desktop PDF readers: a blurred preview displays a prompt to 'open secure document' that directs victims to external payloads, while embedded scripts can fetch malware if a user grants permission. Because the malicious content is only retrieved after user interaction, Gmail's automated scanners and attachment sandboxes can be bypassed. Security experts recommend stronger webmail controls, robust attachment sandboxing, endpoint detection, and frequent, realistic user awareness training.
