T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by ML classifiers and ClamAV, specifically identified as a phishing trojan. The document body, though partially corrupted, contains references to 'Java 8 windows 10 32 bit' and an external URI pointing to 'trafffi.ru', suggesting a lure to download a malicious payload disguised as a software installer. No scripts were extracted, but the presence of external URLs and the phishing classification strongly indicate a malicious intent.

-
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://trafffi.ru/aws?utm_term=java+8++windows+10+32+bit PDF link annotation
