T1566.001 Spearphishing Attachment
The PDF was identified as an image-only lure, a common phishing technique to trick users into clicking on a hidden link. The embedded URL, https://bit.ly/3E1Xxgz, leads to a URL shortener, which is often used to obscure malicious destinations. While the URL itself was flagged as benign, the overall structure and heuristic firings strongly suggest a phishing attempt.

Image-only PDF lure links through URL shortener high PDF_IMAGE_LURE_SHORTENER_LINKPDF 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_LUREPDF has 1 image(s), only 0 text block(s), carries a click-outward action, and is only 124 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
