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

The PDF file contains a link to a redirector URL, which is a common tactic for distributing malware. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms this, pointing to 'https://ttraff.cc/pify?keyword=game+god+of+war+2+apk+android'. Additionally, the 'SE_PASSWORD_ARCHIVE_LURE' heuristic indicates that the document is designed to trick users into downloading a password-protected archive, likely to bypass security scans. The document body itself contains the malicious URL and a link to a seemingly benign PDF on Shopify, which is part of a link farm.

Heuristics 4

  • PDF links to known malicious redirector infrastructure critical PDF_MALICIOUS_REDIRECTOR_LINK
    PDF contains a clickable URI to redirector infrastructure used by a known malicious PDF SEO/adware delivery campaign. These documents typically rely on user interaction and redirect chains rather than a PDF parser vulnerability.
  • 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.
  • 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
  • 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.
