T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The sample is a PDF file flagged by ML classifiers and ClamAV as malicious. It contains an embedded URI pointing to a suspicious domain, trafffe.ru, which is likely used to host a phishing page or a second-stage payload. The document body appears to be malformed or obfuscated, preventing a clear understanding of its content, but the presence of the malicious URI strongly suggests a phishing or malware delivery attempt.

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://trafffe.ru/123?utm_term=robert%2527s+rules+of+order+for+small+boards+pdf PDF link annotation
