MITRE ATT&CK

T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links to other PDF files hosted on various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content. The primary heuristic identified a mass of external PDF links, suggesting a coordinated effort to direct users to these external resources. No scripts were extracted from this sample.

Heuristics 3

Embedded URL info EMBEDDED_URL
