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

The PDF document contains a mass of external links, identified by the PDF_SEO_LINK_FARM heuristic, designed to drive traffic to various domains. The document body includes a deceptive title related to 'Minecraft for Mac version' and embedded URLs, suggesting a lure to trick users into visiting potentially malicious sites. The primary intent appears to be SEO manipulation and potentially directing users to phishing or malware distribution sites.

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.
