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

The PDF file exhibits characteristics of a phishing lure, as indicated by the 'SE_URGENCY_LURE' heuristic and the presence of numerous embedded URLs. The 'PDF_SEO_LINK_FARM' heuristic specifically highlights a large number of external PDF links, suggesting an attempt to distribute malicious content or redirect users to phishing sites. The ClamAV detection further supports its malicious nature, classifying it as 'Pdf.Phishing.TtraffRobotInstall'.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
