MITRE ATT&CK
T1204.002 Malicious Link/URL T1566.002 Spearphishing Attachment T1027 Obfuscated Files or Information

The PDF file contains a link to a redirector URL that appears to be part of a link farm, likely intended for SEO manipulation to attract users searching for cracks. The document also contains instructions to disable security software, a common tactic used by malware distributors. The embedded URL 'https://ttraff.me/wix?keyword=miracle+crack+2.+58+setup' is flagged as malicious, suggesting it leads to harmful content. The presence of numerous benign Shopify links is likely a tactic to mask the malicious redirector.

Heuristics 5

  • 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.
  • Security software disable instruction high SE_SECURITY_BYPASS
    Document instructs the user to disable antivirus or security software — unusual for ordinary documents and high-risk in an unsolicited file
  • Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTON
    Document contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
  • 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.
