MITRE ATT&CK
T1566.002 Spearphishing Attachment

The PDF file contains a large number of embedded links, identified by the PDF_SEO_LINK_FARM heuristic. These links point to various URLs, predominantly hosted on 'linkpc.net', suggesting a link farm or traffic redirection scheme. While the document body is heavily obfuscated and unreadable, the presence of numerous external links indicates an attempt to direct users to potentially malicious content or phishing sites. No scripts were extracted from this sample.

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.
