T1059.007 JavaScript
T1203 Exploitation for Client Execution
The file is identified as malicious by ClamAV and an ML classifier, with heuristics indicating the presence of external URIs and potential command execution. The embedded URL `https://nipisod.ru/strik?utm_term=arduino+language+reference+italiano` is suspicious and likely leads to a phishing page or malware download. The document body is heavily obfuscated, preventing a clear understanding of its specific lure, but the overall indicators point to a phishing or malware delivery attempt.

LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMANDExtracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.

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=arduino+language+reference+italiano PDF link annotation
