The PDF document contains a large number of external links, identified by the PDF_SEO_LINK_FARM heuristic, pointing to various domains. One of these links, http://fwtrail.org/uploads/1/3/0/2/130272377/130272377.html#2017+chevy+volt+premier+review, is directly embedded in the document body. The presence of the SE_LOLBIN_RUN_COMMAND heuristic indicates that the document likely contains instructions for executing commands using Windows scripting tools, further suggesting a malicious intent to redirect or download additional payloads.

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.
