MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as malicious by multiple heuristics, including a machine learning classifier and ClamAV, which flagged it as a phishing trojan. The 'PDF_IMAGE_LURE' heuristic indicates that the document is primarily image-based, designed to trick users into interacting with a hidden clickable element. This element likely leads to the external URI found in the document, which is a phishing-related URL.
