T1566.001 Spearphishing Attachment
T1059.007 JavaScript
T1203 Exploitation for Client Execution
T1059.001 PowerShell
The PDF document contains numerous external links, many pointing to disposable hosting, suggesting a link farm or SEO poisoning tactic. A critical heuristic indicates a lure for clipboard command execution, instructing users to paste content into a shell. This, combined with the ClamAV detection and ML classifier flagging, strongly suggests the document is designed to trick users into executing malicious commands, likely to download and run a secondary payload. No scripts were extracted, but the presence of external URLs and the command lure are sufficient indicators.

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.

Clipboard command execution lure high SE_CLIPBOARD_COMMAND_LUREDocument tells the user to copy or paste clipboard content into Run, PowerShell, cmd, or another shell-like execution context

Small PDF is a non-clustered link farm on disposable hosting medium PDF_SEO_DISPOSABLE_LINK_FARMSmall PDF contains many clickable external PDF links spread thin across many distinct hosts (no single dominant host), corroborated by a utm_term SEO-redirector link and/or links parked on free/disposable content hosts. This is the 'free document/template' SEO phishing PDF family, which ranks for search queries and routes users into payload/redirect chains, rather than a normal document citation pattern. The PDF itself carries no exploit — the risk is the linked destinations.

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://maypoin.ru/wix?keyword=google+translate+blocked+websites PDF link annotation
