MITRE ATT&CK
T1566.001 Spearphishing Attachment
T1204.002 User Execution: Malicious File
T1059.007 JavaScript
The PDF document contains a social engineering lure, specifically a 'ClickFix' attack, instructing the user to execute a command to resolve a perceived issue with Adobe Reader. This is supported by the 'SE_CLICKFIX' and 'SE_ENABLE_LURE' heuristic firings. The document also contains numerous external links, suggesting it is part of a larger phishing or malware distribution scheme. While no scripts were explicitly extracted, the PDF structure and heuristics indicate malicious intent, likely to download a second-stage payload.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
ClickFix social engineering attack high SE_CLICKFIXDocument instructs the user to press Win+R or paste a command into a terminal — consistent with ClickFix attacks that bypass macro restrictions by tricking users into running malicious commands directly
-
Macro/content-enable lure medium SE_ENABLE_LUREDocument instructs the user to enable macros or editing — a common technique used by malware droppers to bypass Office macro security settings
-
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://lozipotod.ru/strik?utm_term=adobe+reader+dc+freezes+windows+10 PDF link annotation
