MITRE ATT&CK
T1059.001 PowerShell T1204.002 Malicious File

The PDF contains a large number of external links, many pointing to PDF files on various domains, indicating a link farm or SEO spam tactic. The heuristic 'SE_LOLBIN_RUN_COMMAND' suggests the document may contain instructions for executing commands, potentially to download or redirect to malicious content. The presence of multiple external URLs, including one that appears to be a direct link to an HTML file, supports the attack pattern of luring users to external sites. No scripts were extracted from this sample.

Heuristics 4

  • 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.
  • Visible LOLBin command execution instruction high SE_LOLBIN_RUN_COMMAND
    Document contains instructions or visible command text involving Windows script/execution tools such as PowerShell, mshta, cmd, rundll32, or regsvr32
  • 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.
