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

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic, suggesting a link farm or redirection to malicious sites. ClamAV also detected this file as Pdf.Phishing.TtraffRobotInstall-7605656-0. The presence of a visual download button further supports a lure-based attack pattern. The document body, though heavily obfuscated, contains numerous URLs pointing to PDF files, reinforcing the link farm detection.

Heuristics 4

  • 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.
