MITRE ATT&CK
T1566.001 Spearphishing Attachment T1059.007 JavaScript T1203 Exploitation for Client Execution

This PDF file contains numerous links to external websites, a common tactic for phishing or malware distribution. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' indicates that at least one of these links directs to known malicious infrastructure, specifically 'https://ggtraff.ru/aws?utm_term=game+pacify+crack'. The presence of a large number of PDF links and the ML classifier's high confidence score further support its malicious nature. No scripts were extracted, but the document's structure and embedded links strongly suggest it's designed to redirect users to harmful content.

  • 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.
  • 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.
