T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was flagged by a machine learning classifier and ClamAV as malicious, specifically indicating a phishing or trojan. The heuristic 'SE_CALLBACK_LURE' suggests a callback phishing or tech-support scam pattern. An external URI pointing to 'nipisod.ru' was extracted, which is likely the malicious destination. No scripts were extracted from this sample, but the overall pattern suggests a phishing lure to a malicious URL.

-
Callback phishing phone lure medium SE_CALLBACK_LUREDocument asks the user to call a phone number in billing, refund, subscription, fraud, or security context — consistent with callback phishing or tech-support scam patterns. Suppressed for legitimate-issuer (IRS/gov/official-form) documents that carry no urgency or charge/dispute escalation.
-
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://nipisod.ru/strik?utm_term=mobile+home+coleman+furnace+parts+diagram PDF link annotation
