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

The PDF document contains a large number of external links, a technique often used to create SEO link farms or to redirect users to malicious sites. The document body mentions 'Thule 3 bike hitch mount', suggesting a lure to attract clicks. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass of external links, with 'acadianarefinishing.com' being a dominant host. This suggests the primary purpose is to drive traffic to potentially compromised or malicious websites.

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.

  • Embedded URL info EMBEDDED_URL
