T1566.001 Spearphishing Attachment
T1203 Exploitation for Client Execution
The PDF document was flagged by ML classifiers and ClamAV as malicious, exhibiting characteristics of a phishing or trojan delivery mechanism. The heuristic 'SE_REMOTE_SUPPORT_LURE' indicates the document's content likely instructs the user to engage with remote support tools, a common tactic for social engineering attacks. While no scripts were directly extracted, the presence of numerous embedded URLs, many pointing to potentially disposable domains, suggests a link farm or redirection infrastructure used to host or deliver malicious payloads.

Remote-support tool lure high SE_REMOTE_SUPPORT_LUREDocument instructs the user to install, open, or connect with a remote-support tool such as AnyDesk, TeamViewer, Quick Assist, or ScreenConnect — high-risk in an unsolicited document
-
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 http://fine-cottage.ru/userfiles/file/54797153460.pdf In PDF document text
