T1566.001 Spearphishing Attachment

This PDF document is designed as a lure, presenting a screenshot of content with a clickable element that redirects to the URL https://cctraff.ru/aws?keyword=games+games+to+play+online. The heuristic 'PDF_MALICIOUS_REDIRECTOR_LINK' confirms this URL is associated with malicious redirector infrastructure. The ML classifier also strongly indicates maliciousness. The document's structure and the embedded URL suggest an attempt to phish credentials or deliver a secondary payload.

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.
  • Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LURE
    PDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 18 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • 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.
