T1566.002 Spearphishing Attachment
T1204.002 Malicious Link
The PDF is encrypted, preventing deeper static analysis of its contents. However, heuristics indicate it is an image-only document with an action trigger, a common technique for phishing lures. The small file size and image-only nature suggest it's a screenshot designed to hide a clickable element, likely leading to a malicious URL or prompt for user interaction.

Heuristics 3
-
Image-only document with action trigger (screenshot lure) medium PDF_IMAGE_LUREPDF has 2 image(s), only 0 text block(s), carries a click-outward action, and is only 96 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
-
Encrypted PDF (string and stream contents are opaque to static scan) info PDF_ENCRYPTEDPDF declares /Encrypt — string objects and stream contents are encrypted with the standard security handler (RC4 or AES). On its own this is informational; legitimate encrypted documents include signed contracts, billing statements, and rights-managed material. Static heuristics cannot inspect encrypted payload bytes.
-
Embedded URL info EMBEDDED_URLOne 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://www.microsoft.com/typography/ctfontshttp://fontfabrik.comYou In PDF document text
