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

The PDF file contains numerous external links, many of which point to seemingly unrelated domains and are structured to appear as SEO-optimized content. The document body, though partially corrupted, includes a URL that mimics a software download page for 'Kodak scanmate i1120 software'. This suggests a lure to trick users into downloading malware disguised as legitimate software. The presence of a PDF_SEO_LINK_FARM heuristic firing further supports the interpretation that this document is part of a link farm or SEO poisoning campaign designed to distribute malicious content.

Heuristics 3

  • Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARM
