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

The PDF file contains a large number of external links, many of which are SEO-optimized PDF lures. The document body text mentions 'India visa application form for tourist', suggesting a social engineering pretext to drive traffic to these malicious links. The primary heuristic 'PDF_SEO_LINK_FARM' indicates a deliberate attempt to create a link farm, likely for SEO manipulation or to host malicious content. The presence of multiple unknown URLs further supports this. No scripts were extracted from this sample.

Heuristics 3

  • 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.
  • 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.
