MITRE ATT&CK
T1566.002 Phishing: Spearphishing Attachment

The PDF document contains a large number of embedded URLs pointing to external PDF files hosted on the domain loaminoo.linkpc.net. This technique is often used for SEO poisoning or to distribute malicious content. No scripts were extracted from this sample, and the document body primarily consists of these links. The primary attack pattern observed is the distribution of numerous links to external resources.

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.
