MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains a large farm of external links, many of which are advertised as cracked software. The heuristic 'PDF_SEO_LINK_FARM' indicates a mass external link farm, and 'PDF_CRACKED_SOFTWARE_LURE' specifically identifies links advertising pirated software. The primary malicious URL identified is http://seachtop.com/comprehend/enron/lious/autoship/rubus=UGhvdG9zaG9wIDIwMjIUGh.ZG93bmxvYWR8b3I4TlhvMGIzeDhNVFkxTmprNE1UVXdOSHg4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA, which likely serves as a download or redirection point for malicious payloads. The document's structure and content suggest it is part of a phishing campaign to trick users into downloading potentially harmful software.

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.
  • PDF link farm advertises cracked/pirated software medium PDF_CRACKED_SOFTWARE_LURE
    PDF contains many clickable links whose targets use cracked-software, keygen, serial-key, or warez vocabulary. These are SEO-spam lure documents that rank for software-piracy searches and route users to fake 'crack' download pages distributing potentially-unwanted programs, adware, or droppers. The PDF itself carries no exploit — the risk is the linked destinations.
  • 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.
