MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document is identified as malicious by ClamAV and an ML classifier. It employs a common phishing tactic by presenting itself as an image-based lure, likely a screenshot, to entice users to click on an embedded URI. The primary malicious indicator is the external URI pointing to 'traffking.ru', which is likely used to host a phishing page or deliver a secondary payload.
