MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 Malicious Link

The PDF document contains a large number of external links to other PDF files hosted across various domains. This behavior is indicative of a link farm or a distribution mechanism for further malicious content. The document body text, though partially corrupted, mentions 'Hindi typing word practice pdf' and includes the wkhtmltopdf application name, suggesting a potential lure for users seeking specific content. The primary attack pattern involves directing users to these external resources, which could host phishing pages, malware, or other harmful content.

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.
