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

The PDF was detected by ClamAV as Pdf.Phishing.TtraffRobotInstall-7605656-0. Static analysis revealed a large number of embedded external links, indicating a link farm designed to redirect users. The primary heuristic firing, PDF_SEO_LINK_FARM, confirms this behavior, with 31 external PDF links found. The document body contains garbled text, suggesting it is not intended for human readability but rather to host these links.

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.
