Adversaries may enumerate information about browsers to learn more about compromised environments. Data saved by browsers (such as bookmarks, accounts, and browsing history) may reveal a variety of personal information about users (e.g., banking sites, relationships/interests, social media, etc.) as well as details about internal network resources such as servers, tools/dashboards, or other related infrastructure.(Citation: Kaspersky Autofill) Browser information 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 information is typically stored in local files and databases (e.g., `%APPDATA%/Google/Chrome`).(Citation: Chrome Roaming Profiles)
Scripting or CLI tool access to ~/Library/Application Support/Google/Chrome or ~/Library/Safari bookmarks, cookies, or history databases. Detection relies on unexpected processes accessing or reading from these locations.
Unauthorized shell or script-based access to browser config or SQLite history files, typically in ~/.config/google-chrome/, ~/.mozilla/, or ~/.var/app folders, indicating enumeration of bookmarks or saved credentials.
Access to browser artifact locations (e.g., Chrome, Edge, Firefox) by processes like PowerShell, cmd.exe, or unknown tools, followed by file reads, decoding, or export operations indicating enumeration of bookmarks, autofill, or history databases.
