MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF contains a large number of external links, many of which point to other PDF files, suggesting a link farm for SEO or malicious redirection. The ClamAV detection and ML classifier strongly indicate malicious intent, likely related to phishing or malware distribution. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' suggests the document may be part of a multi-stage attack where a password is provided to decrypt a subsequent payload.

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
