T1204.002 Malicious File Execution: Malicious Applet
This PDF document was flagged by multiple heuristics as malicious, including a high-confidence ML classification and ClamAV detection. The 'SE_BROWSER_INSTALL_LURE' heuristic indicates the document's primary purpose is to trick the user into installing a fake browser extension or update. While numerous URLs were extracted, they are all marked as benign and likely serve as decoys or part of the lure. No scripts were extracted from this sample.

Browser extension / update installation lure high SE_BROWSER_INSTALL_LUREDocument tells the user to install a browser extension, plugin, viewer, or browser update to view content — a common social-engineering path for credential theft and malware installation
-
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://feedproxy.google.com/~r/sq/ugae/~3/9xivtwLAy4k/square?utm_term=linear+equations+for+class+6+cbse+worksheets
