MITRE ATT&CK

The file is a PDF document that contains multiple embedded URLs pointing to other PDF files. The ClamAV heuristic indicates this is a phishing attempt, likely designed to trick users into downloading further malicious content. The document body itself is largely garbled but contains references to the embedded URLs, reinforcing the lure.
