T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a clickable link to an algorithmically-generated URL, identified as malicious by heuristics and ClamAV. This suggests the document is designed to redirect users to a potentially harmful website, likely for phishing or to download further malware. The presence of parser-evasion techniques further indicates malicious intent.

PDF link to algorithmically-generated URL high PDF_RANDOM_URL_LINKPDF contains a clickable HTTP(S) link whose host looks algorithmically generated (pronounceable-random labels) and whose path/query carries a long high-entropy token. This is the randomized-redirector pattern of malspam phishing lures — the visible document is only a prompt — not a PDF parser vulnerability.
-
Clickable PDF combines external action with parser-evasion structure high PDF_ACTION_PARSER_EVASIONPDF has an external clickable URI together with object graph or xref structures that make parsers disagree, such as divergent duplicate objects, parser divergence, or xref offset mismatch. That combination is stronger than a plain link: the document is both an outward-action carrier and a parser-confusion/evasion sample.

External URI info PDF_URIPDF contains an external URL action
-
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTALThe same indirect object (N G) is defined more than once with different body bytes. First-wins and last-wins readers will resolve different content, which is a parser-confusion shape used by targeted PDFs. Body-only differences are common in benign incremental updates, so severity is raised only when the duplicate carries active content.

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.iddqd.ru/download?idclick=https://assets.website-files.com/65dca6142108eef8408d6378/66355bbae637ae2f3a1cb17b_75235177244.pdf&title=Lt.%20Typhon&where=mods&what=%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD%EF%BF%BD+%EF%BF%BD%EF%BF%BD+ZDoom.org In PDF document text
