T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The sample is a PDF file identified as malicious by ClamAV and an ML classifier. It utilizes invisible links to redirect users to a URL that hosts a ZIP archive, indicated by the 'PDF_REPEATED_PAYLOAD_LINK_LURE' heuristic. The primary malicious URL identified is https://soxebez.ru/wix?keyword=deck+heroes+cheats+tool.zip, which likely serves as a distribution point for a second-stage payload. The presence of embedded URLs and the nature of the heuristics suggest a phishing or malware delivery attempt.

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.
-
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://soxebez.ru/wix?keyword=deck+heroes+cheats+tool.zip In PDF document text
