MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The file is identified as malicious by a machine learning classifier and ClamAV with a signature indicating phishing and trojan activity. An external URI pointing to 'trafficel.ru' was extracted, suggesting a potential phishing lure or command and control communication. Although no scripts were directly extracted, the PDF structure and embedded URI indicate a malicious intent to redirect the user to a harmful site.

External URI info PDF_URI

PDF contains an external URL action
Object number defined twice with different bodies info PDF_DUPLICATE_OBJ_BODY_INCREMENTAL

The 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_URL

One 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://trafficel.ru/aws?utm_term=jordan+canonical+form+minimal+polynomial+example
