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

The PDF file contains a link farm designed to redirect users to multiple external PDF files. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the PDF_SEO_LINK_FARM heuristic strongly indicate a phishing or malicious redirection attempt. 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.
