T1566.001 Spearphishing Attachment
T1059.007 JavaScript
This PDF file was detected as malicious by ML classifiers and ClamAV, indicating a phishing attempt. The document body, though truncated, suggests a lure related to 'Pearson envision 2020 log in'. The presence of numerous external links, including one to 'traffnew.ru', points towards an attempt to redirect users to a malicious site for credential harvesting or further exploitation. The PDF structure itself contains multiple embedded links, consistent with a link farm or phishing distribution method.

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://traffnew.ru/123?keyword=pearson+envision+2020+log+in
