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

The PDF file was detected by ClamAV as Pdf.Phishing.TtraffRobotInstall-7605656-0. Static analysis revealed a large number of embedded external links, indicating a potential link farm or phishing lure. The document body contains a mix of seemingly random text and URLs, further supporting the phishing or SEO manipulation attack pattern. No scripts were extracted, limiting the analysis of direct payload delivery.

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.
