MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF file contains a large number of embedded links to other PDF files, masquerading as a Cambridge English placement test. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass external PDF link farm, suggesting a phishing or scam campaign. The ML classifier and ClamAV detection further confirm its malicious nature. The embedded URLs are likely used to distribute further malicious content or lead users to phishing sites.

  • 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.
  • 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.
