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

The PDF file was detected by ClamAV as 'Pdf.Phishing.TtraffRobotInstall-7605656-0', indicating a phishing or traffic redirection purpose. The heuristic 'PDF_SEO_LINK_FARM' confirms the presence of a large number of external links, many with numeric slugs, suggesting an attempt to manipulate search engine results or redirect users to potentially malicious content. The document body contains a mix of technical terms and the same URLs found in the heuristics, reinforcing the link farm attack pattern.

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.
