T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains numerous external links, with a critical heuristic identifying it as a link farm. One prominent external URI, 'https://crophysi.ru/aws?utm_term=xbox+360+controller+won%2527t+turn+on', suggests a lure related to a common search query. The presence of many PDF links, including one to 'https://s3.amazonaws.com/sinadi/begikezok.pdf', indicates a potential distribution mechanism for further malicious content. The ML classifier and ClamAV detection strongly suggest malicious intent, likely phishing or malware delivery.

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://crophysi.ru/aws?utm_term=xbox+360+controller+won%2527t+turn+on
