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

The PDF contains a link farm of external PDF files, disguised as Aadhaar form downloads, which is a common lure for phishing or malware distribution. The ML classifier and ClamAV detection strongly indicate malicious intent, likely to deliver a second-stage payload via the embedded URLs. No scripts were extracted, but the PDF structure and embedded URLs are sufficient to infer a malicious download attempt.

  • 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.
  • 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.
