MITRE ATT&CK

T1566.001 Spearphishing Attachment T1059.007 JavaScript

The PDF file contains an embedded URL that appears to be a lure for job seekers interested in Wizz Air cabin crew positions. This URL, 'https://trafffi.ru/wb?keyword=wizz%20air%20careers%20cabin%20crew%20salary', is flagged as suspicious and likely leads to a phishing page or a download of malicious content. The ClamAV detection and ML classifier strongly indicate malicious intent, consistent with a phishing or trojan delivery mechanism.

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.
