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

The PDF file contains multiple embedded links that point to external PDF files, with one link directly pointing to an HTML file that likely hosts a payload. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' and the ML classifier further indicate malicious intent. The document body, while containing unrelated text, also embeds these suspicious URLs, suggesting a phishing or social engineering lure.

Heuristics 4

  • PDF link points directly to executable/archive payload critical PDF_DIRECT_PAYLOAD_LINK
    PDF contains a clickable HTTP(S) URI whose path ends in an executable, script, shortcut, disk image, or archive extension. Documents can legitimately link to installers, so this is a high-risk delivery indicator rather than a standalone exploit fingerprint.
  • ClamAV: Pdf.Phishing.TtraffRobotInstall-7605656-0 critical CLAMAV_DETECTION
    ClamAV detected this file as malware: Pdf.Phishing.TtraffRobotInstall-7605656-0
