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

The PDF document contains a large number of external links, many pointing to other PDF files, suggesting a link farm or SEO poisoning tactic. The document body, though heavily obfuscated, contains text related to 'unified portal member epf india government.in' and includes a URL that appears to be part of this lure. The presence of a 'PDF_SEO_LINK_FARM' heuristic firing and a 'SE_CALLBACK_LURE' heuristic strongly indicate a phishing or scam attempt designed to direct users to malicious sites or solicit phone calls. No scripts were extracted from this sample.

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.
  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
  • 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.
