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

The PDF contains a large number of embedded URLs pointing to other PDF files, indicative of a link farm designed to host malicious content. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the 'PDF_SEO_LINK_FARM' heuristic strongly suggest a phishing or malware distribution campaign. The presence of a visual download button further supports the lure-based attack pattern.

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.

  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
