T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The file is identified as malicious by ML classifiers and ClamAV, with a critical heuristic firing for ClamAV detection. An external URI pointing to 'pelibifir.ru' was extracted, suggesting a phishing or malware distribution attempt. The document body, though partially corrupted, contains text related to congratulations, which is likely a lure. No scripts were extracted, but the presence of embedded URLs and the overall detection profile strongly indicate a malicious intent, likely related to phishing or malware delivery.

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://pelibifir.ru/strik?utm_term=do+you+say+congratulations+when+someone+gets+married
