T1566.001 Spearphishing Attachment
T1059.007 JavaScript
T1190 Exploit Public-Facing Application
The PDF contains multiple embedded URLs, many of which point to disposable hosting and are part of link farms, suggesting a phishing or malware distribution campaign. The heuristic 'SE_MFA_LURE' indicates the document likely attempts to harvest credentials or session tokens by impersonating an MFA prompt. The ML classifier also strongly flagged this PDF as malicious. No scripts were extracted, but the presence of numerous suspicious URLs and the MFA lure strongly suggest a phishing attack.

Heuristics 6
-
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
-
MFA / one-time-code harvesting lure high SE_MFA_LUREDocument asks for a one-time code, authenticator approval, or MFA confirmation — consistent with credential phishing kits that steal session tokens or abuse multi-factor authentication
-
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://dafemum.ru/strik?utm_term=how+to+reset+disabled+iphone+without+computer PDF link annotation
