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

The PDF document contains a large number of external links, many of which are numerically or generically named PDF files hosted on various domains. One specific link, 'http://minnesotahydrographics.com/uploads/1/3/0/5/130588337/130588337.html#setup+linksys+e2500+without+cd', suggests a lure related to router setup. This indicates a likely phishing or malware distribution attempt, leveraging a link farm to obscure the malicious intent.

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.
