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

The PDF contains a large number of embedded links to external PDF files, a technique often used for SEO manipulation or to distribute malware. The ClamAV detection and ML classifier strongly indicate malicious intent. The heuristic 'PDF_SEO_LINK_FARM' directly identifies the mass linking behavior, with the primary domain being 'bandito.agency'. No scripts were extracted, but the document body, though truncated, contains references to Adobe PDF Library and unrelated text, suggesting it's primarily a container for the malicious links.

  • 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.
