MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains a large number of external links, many of which point to cracked software. One of the embedded URLs, http://evacdir.com/doughboy.amsterdal.ZXBzb24gdHg3MTB3IGFkanVzdG1lbnQgcHJvZ3JhbQZXB?initiator=drive&ZG93bmxvYWR8OXhxWVhCNVlueDhNVFkxTlRnME1qazRNWHg4TWpVNU1IeDhLRTBwSUZkdmNtUndjbVZ6Y3lCYldFMU1VbEJESUZZeUlGQkVSbDA=pathfinder, is likely a malicious download URL. 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

  • Embedded URL info EMBEDDED_URL
