T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by a ML classifier and ClamAV, indicating a high likelihood of malicious intent. The document body, though partially garbled, contains text suggesting it is a "Reddy heater parts list", likely a lure to disguise the embedded malicious URL. The primary IOC is the external URI pointing to jumiwimov.ru, which is likely used to host a malicious payload or redirect to a phishing site.

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://jumiwimov.ru/strik?utm_term=reddy+heater+parts+list
