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

The PDF file contains a link farm with multiple external URLs, a common technique for SEO poisoning or phishing lures. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the heuristic 'PDF_SEO_LINK_FARM' strongly indicate a phishing or malicious redirection attempt. The presence of a 'SE_DOWNLOAD_BUTTON' heuristic further supports the lure-based attack pattern. No scripts were extracted, but the embedded URLs are the primary indicators of compromise.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
