MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is designed as an image-only lure, presenting a screenshot to entice users to click on an embedded link. This link, identified as a malicious redirector, leads to the URL https://gettraff.ru/aws?keyword=1996+jeep+grand+cherokee+speaker+size. The file's structure and the nature of the embedded link strongly suggest a phishing attempt aimed at redirecting users to potentially harmful content.

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.
