MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF document contains embedded links that lead to known malicious redirector infrastructure, specifically promoting free Robux or game hacks. The ML classifier strongly indicated maliciousness, and the presence of a visual download button further supports a social engineering lure. The document's content and linked URLs suggest a phishing attempt to trick users into visiting malicious sites.

Heuristics 3

  • 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.
  • 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.
