MITRE ATT&CK
T1566.002 Spearphishing Attachment T1204.002 Malicious Link

The PDF file was flagged by ClamAV as Pdf.Phishing.TtraffRobotInstall-7605656-0. Static analysis revealed a significant number of embedded URLs, indicative of a link farm designed to distribute malicious content. The heuristic PDF_SEO_LINK_FARM specifically highlights this behavior, with multiple URLs pointing to various domains, all likely serving as lures.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
    Small PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
