T1204.002 Malicious Link
T1566.002 Spearphishing Attachment
The PDF file contains multiple invisible links pointing to a ZIP archive hosted on an IP address. ClamAV identifies this as Pdf.Trojan.QBot, and heuristics indicate it's an image-based lure designed to trick users into downloading a payload. The embedded URL is the primary indicator of the malicious payload delivery.

Invisible/repeated PDF links deliver payload file critical PDF_REPEATED_PAYLOAD_LINK_LUREPDF uses invisible link annotations and points to a direct payload download. Repeated invisible links or lure-like payload names such as document/unlock/verify archives match malware-delivery PDF carriers where the page is only a prompt and the real payload is fetched from the linked URL.

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 116 KB — typical shape of a phishing lure where a full-page screenshot hides a clickable button that launches or submits to an attacker URL.
-
Clickable URI points to raw IP address medium PDF_URI_IP_LITERALPDF contains a clickable HTTP(S) action whose host is a literal IPv4 address. Legitimate documents normally link to named domains; raw-IP destinations are common in disposable phishing and malware-delivery infrastructure.
