MITRE ATT&CK
T1566.001 Spearphishing Attachment T1204.002 User Execution: Malicious File

The PDF document contains a large number of external links, many of which advertise cracked or pirated software. One of the embedded URLs, http://mydrugdir.com/aprox/botteltje.cami/unfoldment.ZG93bmxvYWR8UWgxTVdKd2FYeDhNVFkxTmpnNU1qTTFNbng4TWpVNE4zeDhLRTBwSUVobGNtOXJkU0JiUm1GemRDQkhSVTVk.T0JKIGFuZCBKU09OIENvbnZlcnRlcgT0J, is particularly suspicious and likely serves as a download source for malware. The document's structure and content strongly suggest a lure for users seeking illegal software, which is a common tactic for distributing malware.

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.
