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

The PDF file contains a large number of embedded URLs pointing to external PDF documents on the domain 'lwoscmobook.myhome.cx'. This is indicative of a link farm or SEO spam campaign, which is often used to distribute malware or phish for credentials. No scripts were extracted from this sample, and the document body was heavily obfuscated, limiting further analysis of the immediate intent beyond the link farm. The primary attack pattern observed is the distribution of malicious links.

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.
