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

The PDF document contains a large number of external links, many of which are designed to appear as legitimate software downloads but are actually lures for 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 a secondary payload. The document's structure and content strongly suggest a phishing or malware distribution attempt.

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.
