MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of external links, forming a link farm. The primary heuristic indicates this is a SEO spam technique, likely intended to drive traffic to malicious sites or to host further malicious content. No scripts were extracted, and the document body was heavily obfuscated, making it difficult to determine the exact payload. The embedded URLs are the main indicators of malicious activity.

Heuristics 2

  • 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.
