T1059.007 JavaScript
This PDF file was flagged by a machine learning classifier and ClamAV as malicious. It contains a link farm of numerous PDF files hosted on various domains, with a specific focus on keywords like 'kartilya ng katipunan pdf english'. The heuristic 'SE_PASSWORD_ARCHIVE_LURE' indicates that the document likely instructs the user to open a password-protected archive, a common tactic to evade initial gateway scanning. No scripts were extracted, but the overall structure suggests a phishing or malware distribution attempt.

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://nipisod.ru/award?keyword=kartilya+ng+katipunan+pdf+english PDF link annotation
