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

The PDF file contains embedded JavaScript and a large number of external links, indicative of a phishing or malware distribution scheme. The ClamAV detection 'Pdf.Phishing.TtraffRobotInstall-7605656-0' further supports this assessment. The embedded JavaScript likely facilitates the redirection or download of malicious content from the linked URLs.

Heuristics 4

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • Embedded JS stream low PDF_JS
    PDF references a /JS stream. Generic JavaScript is common in benign forms; specific dangerous APIs are scored by separate rules.
  • Embedded URL info EMBEDDED_URL
    One or more URLs were extracted from the document. The URL itself is not a detection — see the per-URL labels for which channel (macro, JS, link annotation, document body, ...) reached each URL.
