T1059.007 JavaScript
T1203 Exploitation for Client Execution
The sample is a PDF file flagged by multiple heuristics as malicious, including brand impersonation for credential phishing (INSTAGRAM) and a large number of external links, suggesting a link farm or SEO poisoning attempt. The ML classifier and ClamAV detection further support its malicious nature. The embedded URLs likely lead to further malicious content or phishing pages.

Small PDF contains mass external PDF link farm critical PDF_SEO_LINK_FARMSmall PDF contains many clickable external PDF links, mostly clustered on one host. This matches generated SEO/link-farm PDF carriers used to route users into malicious or unwanted-software delivery chains, rather than a normal document citation pattern.
-
Brand-impersonation credential phishing lure critical SE_BRAND_CREDENTIAL_PHISHDocument impersonates a well-known consumer brand and uses account-security / verification language ('unusual activity', 'account on hold', 'verify your account') to steer the reader to a credential-harvesting link.

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://fokemale.ru/award?keyword=advanced+computer+architecture+notes+for+cse+7th+sem+pdf PDF link annotation
