MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains a large number of external links, identified as a link farm, pointing to various PDF documents hosted on different domains. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the heuristic 'PDF_SEO_LINK_FARM' strongly suggest a phishing or traffic redirection scheme. The embedded URLs are the primary indicators of compromise, likely serving as lures for further malicious activity.

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.
