MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF is identified as an image-only lure, designed to trick users into interacting with a hidden clickable element. This element directs users to external URLs, such as http://wgmyfpb.rxo and http://giicc9b.sed.tiresnwheels4fun.com, which are likely used for phishing or to download further malicious content. The presence of a local builder path alongside remote URIs suggests a sophisticated lure construction.

Heuristics 4

  • Image-only PDF carries local builder path plus remote links high PDF_IMAGE_LURE_LOCAL_FILE_AND_REMOTE_URI
    PDF is an image-only click lure that contains both remote HTTP(S) destinations and a file:/// URI exposing a local Windows/Linux builder path. That co-occurrence is not normal document linking; it matches generated clickbait/phishing carriers where the visible page is a screenshot and the clickable area sends the user to external 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 103 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
  • External URI info PDF_URI
    PDF contains an external URL action
  • 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 http://wgmyfpb.rxo
    • http://giicc9b.sed.tiresnwheels4fun.com
