T1217: Browser Bookmark Discovery
Adversaries may enumerate browser bookmarks to learn more about compromised hosts. Browser bookmarks may reveal personal information about users (ex: banking sites, interests, social media, etc.) as well as details about internal network resources such as servers, tools/dashboards, or other related infrastructure.
Browsers bookmarks may also highlight additional targets after an adversary has access to valid credentials, especially Credentials in Files associated with logins cached by a browser.
Specific storage locations vary based on platform and/or application, but browser bookmarks are typically stored in local files/databases.
This varies in the search since Browser's have their own folders for saving files an example would be Firefox directory found here:: %APPDATA%\Mozilla\Firefox\Profiles\
