MITRE ATT&CK
T1566.001 Spearphishing Attachment

The PDF file is identified as an image-only lure, typical of phishing attacks, where a screenshot is presented as the document content to trick users into clicking a deceptive link. The embedded URL, http://yughglldeclewns.updta78-serv1ce.info, is hosted on a typosquat domain, further indicating malicious intent. The document body contains Russian text suggesting the user should click a button, reinforcing the phishing pretext.

Heuristics 4

  • Image-only PDF lure links to a deceptive (typosquat) host high PDF_IMAGE_LURE_DECEPTIVE_HOST_LINK
    PDF is image-heavy with little real text and its clickable action targets a host that impersonates a security/service/brand word with a look-alike homoglyph substitution — a digit OR a confusable letter (e.g. 'serv1ce', 'servlce', 'upd4te', 'm1cr0s0ft') — on a domain that is not a known-good site. This is a credential-phishing / fake-update carrier shape: a screenshot-like page funnels the victim to a deceptive look-alike destination.
  • 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 10 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.
