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-only lure, encouraging users to click an embedded URI. The heuristic 'PDF_IMAGE_LURE' indicates the document's structure is typical for phishing campaigns, aiming to trick users into navigating to external sites. The primary IOC is the external URI, which likely serves as a gateway to further malicious activity.
