MITRE ATT&CK
T1204.002 Malicious Link T1566.002 Spearphishing Attachment T1059.001 PowerShell

The PDF file contains numerous embedded links, including a critical redirector link to 'https://ttraff.link/wix?keyword=yu+gi+oh+bam+apk+%252B+obb', suggesting a phishing or malware distribution attempt. The document body, though heavily obfuscated, contains references to 'Yu gi oh bam apk obb' and includes multiple PDF links, indicating a lure to download potentially malicious content. The presence of a visual download button and callback lure heuristics further support a malicious intent, likely to trick users into downloading unwanted software or engaging in a scam.

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.
  • Callback phishing phone lure medium SE_CALLBACK_LURE
    Document asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns
  • 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.
    URL https://ttraff.link/wix?keyword=yu+gi+oh+bam+apk+%252B+obb
