T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF contains a clickable link that directs to an algorithmically generated URL, a common tactic for phishing or malware distribution. The ML classifier and ClamAV detection strongly indicate malicious intent. The presence of external actions combined with parser-evasion structures suggests an attempt to exploit vulnerabilities or trick the user into downloading a secondary payload.

-
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 https://www.aquafish.net/pagecon/pagecon.cgi?no=3&page=https://apollos.edu/fckeditor/editor/filemanager/browser/default/browser.html?Connector=https://buvasaw.gmcalaya.com/f/98626&name=%EF%BF%BD%EF%BF%BDi%EF%BF%BDp%EF%BF%BDm%EF%BF%BD%EF%BF%BD%EF%BF%BD%7D In PDF document text
