T1566.001 Spearphishing Attachment
The PDF contains numerous links to external resources, many of which are identified as a link farm on disposable hosting, suggesting a distribution or phishing campaign. The presence of a 'Password-protected archive handoff' heuristic indicates the document likely instructs the user to open a password-protected file, a common tactic to bypass gateway security. ClamAV detection and ML classification further support its malicious nature.

-
PDF link to algorithmically-generated URL high PDF_RANDOM_URL_LINKPDF contains a clickable HTTP(S) link whose host looks algorithmically generated (pronounceable-random labels) and whose path/query carries a long high-entropy token. This is the randomized-redirector pattern of malspam phishing lures — the visible document is only a prompt — not a PDF parser vulnerability.
-
Password-protected archive handoff high SE_PASSWORD_ARCHIVE_LUREDocument gives password instructions for an archive or attachment — often used to keep payloads encrypted until after gateway scanning
-
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://pixomot.ru/uplcv?utm_term=gta+200mb+apk PDF link annotation
