MITRE ATT&CK
T1059.001 PowerShell

The PDF was flagged by an ML classifier and contains a significant number of external links, indicating a potential SEO spam or content distribution tactic. The presence of a 'LOLBin_Run_Command' heuristic suggests that the document may contain instructions or embedded commands for executing system tools, possibly to download and execute further payloads from the linked URLs. No scripts were extracted, limiting the ability to determine the exact execution flow.

Heuristics 3

  • 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
  • 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.
