MITRE ATT&CK
T1566.002 Spearphishing Attachment T1059.001 PowerShell T1204.002 Malicious Link

The PDF contains a large number of external links, including a specific heuristic firing for a 'PDF_SEO_LINK_FARM'. One of the embedded URIs, http://evacdir.com/, is flagged as suspicious. The presence of a remote GoTo action further suggests an attempt to redirect the user to potentially malicious content. The document body is heavily obfuscated and does not provide clear textual lures.

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.
  • Remote GoTo action info PDF_GOTO_REMOTE
    PDF has GoToR/GoToE actions that reference sibling document files — typical of multi-part document bundles
  • 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.
