T1566.001 Spearphishing Attachment
The PDF is identified as an image-only lure, containing a single image and minimal text, designed to trick users into clicking an embedded link. The heuristic 'PDF_IMAGE_LURE' indicates this is a common phishing tactic. The external URI 'http://ydjandk.chrisnkara.com' is the primary indicator of compromise, likely serving as the destination for the malicious click.

Image-only PDF carries local builder path plus remote links high PDF_IMAGE_LURE_LOCAL_FILE_AND_REMOTE_URIPDF 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_LUREPDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 77 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
