T1566.001 Spearphishing Attachment
The PDF document contains a large number of embedded links, many of which point to external PDF files hosted on various domains. The document body, though heavily obfuscated, contains text related to 'Airtel digital tv channel selection' and includes a QR code lure, suggesting a phishing or redirection attempt. The ML classifier strongly flagged this PDF as malicious, and the sheer volume of external links indicates a link farm or redirection strategy.

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.
-
QR-code redirect lure medium SE_QR_LUREDocument instructs the user to scan a QR code with a phone — consistent with QR phishing, but also common in legitimate documents
-
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://74-123-79-170.mgwnet.com/uploads/1/3/0/7/130739664/130739664.html#airtel+digital+tv+channel+selection
