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

This PDF document contains a large number of external links, many of which are advertised as cracked software. The primary link, http://dormister.com/argonaunts.ZG93bmxvYWR8aXA0TlRGblkzeDhNVFkxTnpBek5qSXlNM3g4TWpVM05IeDhLRTBwSUhKbFlXUXRZbXh2WnlCYlJtRnpkQ0JIUlU1ZA.eagles/lipped/moded/dalton/RmlmYSAyMgRml, appears to be a download URL. 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.
  • 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.
