T1566.001 Spearphishing Attachment
T1059.007 JavaScript
The PDF document contains a large number of external links, identified as a link farm, suggesting a deceptive purpose such as SEO manipulation or hosting malicious content. The heuristic 'SE_LOLBIN_RUN_COMMAND' also indicates the presence of a command-line token within the document text, potentially for executing further actions. While no scripts were explicitly extracted, the overall structure and the presence of numerous external URLs point towards a malicious intent to redirect users to potentially harmful sites.

Heuristics 5
-
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.
-
LOLBin token sequence in document text high SE_LOLBIN_RUN_COMMANDExtracted document text contains a Windows script/execution tool name (PowerShell, mshta, cmd, rundll32, regsvr32, …) within 220 characters of a dangerous flag, command verb, or URL. This is a visible 'run this' instruction in HTML/PDF/RTF lure bodies, or — in macro-laden Office files — the macro's own string-pool entries appearing adjacent in extracted text.
-
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://delseronline.com/uploads/1/3/1/4/131454383/131454383.html#piano+sheet+music+happier+ed+sheeran
