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

This PDF document functions as a link farm, directing users to various websites that advertise cracked software and downloads. The document body and heuristics indicate a clear intent to lure users to download potentially malicious software through download gateways and redirectors. The primary URL, http://siteslocate.com/ZG93bmxvYWR8bGQyTVRGcWRqVjhmREUyTlRneU1UZzVPRFY4ZkRJMU9UQjhmQ2hOS1NCWGIzSmtjSEpsYzNNZ1cxaE5URkpRUXlCV01pQlFSRVpk/Rmxhc2hkaWdnZXIgUGx1cyA0LjEuNS4xOTggQWN0aXZhdGlvbiBDb2RlRmx/gained&imaginatively/daytrips.earnhardt, is a prime example of this deceptive tactic.

Heuristics 7

  • 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.
  • Cracked-software lure uses shortlink/download gateway critical PDF_CRACKED_SOFTWARE_SHORTLINK_LURE
    PDF visible text advertises a crack, serial number, archive, or pirated-software download and pairs it with a shortlink or encoded download gateway. This is a high-confidence social-engineering carrier for unwanted software or droppers; the PDF itself is not a parser exploit.
  • Cracked-software lure uses download-gateway redirectors high PDF_CRACKED_SOFTWARE_REDIRECTOR_LINK_FARM
    PDF contains multiple cracked-software/keygen/serial-key lure links together with long encoded download-gateway URLs or known crack-download redirector hosts. This is stronger than generic piracy vocabulary: the document is an SEO lure that funnels users through redirect/download infrastructure commonly used for adware, unwanted software, or droppers.
  • PDF links to a cracked-software download doorway (base64-obfuscated) high PDF_CRACKED_SOFTWARE_DOWNLOAD_DOORWAY
    PDF's embedded link hides a pirated-software title as a base64 blob inside the URL path/query (and/or carries the ``download|`` doorway-template marker), rather than in visible text. This is a TCPDF-generated SEO doorway that ranks for software-piracy searches and funnels users to fake 'crack/keygen' download pages distributing adware, potentially-unwanted programs, or droppers. The base64 encoding is deliberate obfuscation to evade plaintext lure rules; the PDF itself carries no parser exploit — the risk is the linked crack-download destination.
  • 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.
