Following the discovery of the MatrixPDF toolkit on cybercrime forums, researchers observed widespread adoption among threat actors. The toolkit's builder interface allows attackers to load legitimate PDF bait documents and augment them with malicious features including fake overlays, embedded JavaScript actions, and content blurring.
