# T1217 - Browser Bookmark Discovery
## [Description from ATT&CK](https://attack.mitre.org/techniques/T1217)
<blockquote>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.

Browser bookmarks may also highlight additional targets after an adversary has access to valid credentials, especially [Credentials In Files](https://attack.mitre.org/techniques/T1552/001) 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.</blockquote>
