MatrixPDF toolkit converts PDFs into phishing lures

📄 MatrixPDF is a newly observed toolkit that converts ordinary PDFs into interactive phishing and malware lures, researchers report. First seen advertised on cybercrime forums and promoted via Telegram, it embeds blurred content, fake "Secure Document" prompts, clickable overlays and JavaScript actions that redirect users to external payloads. Varonis testing showed these PDFs can bypass Gmail filters because they contain no embedded binaries and rely on user clicks to fetch malicious content. Sellers offer subscriptions from $400/month to $1,500/year.
