T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF file was detected as malicious by ML classifiers and ClamAV, indicating a high likelihood of malicious intent. The 'SE_INVOICE_LURE' heuristic suggests the document's content is designed to deceive users, likely by presenting a fake invoice or payment request. While no scripts were explicitly extracted, the presence of numerous embedded URLs, many pointing to potentially disposable domains, strongly suggests a phishing or malware distribution attempt, likely initiated via spearphishing attachment.

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.
-
Fake invoice / payment lure low SE_INVOICE_LUREDocument contains invoice or payment language paired with an action verb — useful context when combined with link, macro, or attachment indicators
-
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://ewdel.cz/ckfinder/userfiles/files/simalekuzezejixilotosew.pdf In PDF document text
