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

The PDF document contains heuristics indicating it advertises cracked software, with multiple links pointing to such sites. One of the embedded URIs, http://evacdir.com/flyovers/cheapseats.customizations.nonjudgmental?ZG93bmxvYWR8TlQ2Ym1oemZId3hOalUwTkRJeU1ETTJmSHd5TlRnM2ZId29UU2tnU0dWeWIydDFJRnRHWVhOMElFZEZUbDA=TXVsdGlSdW4TXV==, is likely a download link for a second-stage payload. The document body itself is heavily obfuscated and unreadable, providing no direct clues.

Heuristics 3

  • 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
