MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF document contains multiple heuristics indicating a lure for cracked software and password-protected archives, suggesting a multi-stage attack. The embedded URL `http://emailgoal.com/...` is highly suspicious and likely serves as a download or redirection point for malicious payloads. The presence of PDF URI and embedded URL heuristics, along with the cracked software lure, points towards a phishing or social engineering attack vector.

Heuristics 4

  • Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LURE
    Document gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
  • 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.
