T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is a PDF with a high ML classification score and ClamAV detection as a phishing trojan. It contains an embedded URL pointing to a suspicious domain, likely intended to trick the user into downloading malware under the guise of a font. The document body is heavily obfuscated, preventing a clear understanding of its specific lure, but the presence of the external URI and the ML/ClamAV detections strongly indicate malicious intent.

Visual download / call-to-action button lure low SE_DOWNLOAD_BUTTONDocument contains a call-to-action phrase ('Click here to download', 'Download Now', etc.) — low-signal unless other findings point to a malicious workflow
-
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://traffnew.ru/aws?utm_term=avenir+medium+font+free++dafont PDF link annotation
