T1566.001 Spearphishing Attachment
T1204.002 Malicious Link
The PDF was flagged by ML classifiers and ClamAV as malicious. It contains numerous links to external PDF files, suggesting a link farm used for phishing or malware distribution. The heuristics indicate a lure for password recovery secrets or protected archives, implying the document aims to trick users into revealing sensitive information. No scripts were extracted, but the presence of external links and the nature of the lures point towards a phishing or credential harvesting attack.

ClamAV: Pdf.Phishing.Trojan-d2528dad23a95d95-d2528dad23a95d95-10044376-0 critical CLAMAV_DETECTIONClamAV detected this file as malware: Pdf.Phishing.Trojan-d2528dad23a95d95-d2528dad23a95d95-10044376-0
-
Recovery secret / private key request critical SE_SECRET_RECOVERY_LUREDocument requests recovery phrases, private keys, backup codes, or saved passwords. Requests for these secrets in a document are high-risk.
-
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 http://em-mould.com/ckfinder/userfiles/files/64132724133.pdf In PDF document text
