MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large number of external links, many of which appear to be SEO-optimized for book titles or software, suggesting a lure to download potentially malicious files. One specific URL, http://evacdir.com/champneys/faqs.forces?cm9ib21vbmdvIGRvd25sb2FkIGZvciB3aW5kb3dzIDcgMzItYml0IGlzbwcm9=joakim/ZG93bmxvYWR8MVdyYm05eVlYeDhNVFkxTkRrNE9URTJNbng4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk.slumbering/duodenal.circuitry, is directly flagged as an external URI. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' indicates that the document may also provide instructions for accessing password-protected archives, a common tactic to bypass security filters.

Heuristics 4

  • 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.
  • 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
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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.
