T1059.007 JavaScript
The PDF contains multiple external URIs and a URI pointing to a raw IP address, indicating redirection to malicious sites. Heuristics like 'PDF_SEO_DISPOSABLE_LINK_FARM' and 'ML_NYX_PDF_MALICIOUS' further support its malicious nature. ClamAV detection confirms it as a phishing trojan, likely leveraging embedded JavaScript to facilitate the redirection.

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.
-
Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.
