T1566.001 Spearphishing Attachment
This PDF document was flagged by multiple heuristics, including a high-confidence ML classifier and ClamAV detection, indicating malicious intent. The presence of numerous embedded URLs, many pointing to disposable hosting, suggests a link farm or phishing campaign. The 'SE_URGENCY_LURE' heuristic indicates the document likely contains text designed to prompt immediate action, a common tactic in phishing. Although no scripts were explicitly extracted, the PDF structure and URL patterns are consistent with malicious documents designed to redirect users to harmful sites.

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.
-
Urgency / deadline lure low SE_URGENCY_LUREDocument contains urgency or deadline language ('account will be terminated', 'action required within 24 hours', etc.) — useful context, but low-signal without other findings
-
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://onlineadda.net/ckfinder/userfiles/files/renonexagezetotekelik.pdf In PDF document text
