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.

how MITRE says to see it

Detection of Local Browser Artifact Access for Reconnaissance

  • 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.
  • 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.
  • 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.

The description, detection analytics and mitigations are reproduced from MITRE ATT&CK, version 19.2, under its terms of use. The checklists, hunts, labs and everything else linked here are this site’s.
