T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by ML classifiers and ClamAV, with a high-severity heuristic indicating an advance-fee scam lure. The document body, though heavily obfuscated, contains text related to 'how tinder works algorithm' and the embedded URL points to a domain that appears to be part of a phishing or scam campaign. The presence of PDF-specific heuristics suggests exploitation of PDF vulnerabilities to deliver a malicious payload.

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://druttle.ru/wix?keyword=how+tinder+works+algorithm
