MITRE ATT&CK
T1566.001 Spearphishing Attachment

This PDF is designed as an image-only lure, presenting a screenshot to obscure a clickable link. The embedded URL, https://hotnewselon.page.link/6Kc8, is a URL shortener, which is commonly used to obfuscate malicious destinations. The document's structure and the use of a URL shortener strongly suggest a phishing or malware distribution attempt.

Heuristics 3

  • Image-only PDF lure links through URL shortener high PDF_IMAGE_LURE_SHORTENER_LINK
    PDF is image-heavy with little real text and its clickable action points to a URL shortener. This is a high-confidence credential-phishing carrier shape: the visible page is a screenshot-like prompt while the destination is hidden behind redirect infrastructure.
  • 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 37 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.
