Malicious PDF — malware analysis report

Heuristics 7

• 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.
• Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARM
  Small PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. 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.
