.NET

Art.BrowserCookies

Art.BrowserCookies provides rudimentary support for cookie extraction on select browsers. It is a part of the Art archival package set.

Browser Support

Browser / Platform Chrome Edge
Windows v10[1], v20[1], DPAPI[1] v10[1], v20[1], DPAPI[1]
macOS v10[2] v10[2]

[1] v10, v20, and DPAPI refer to cookie encryption types; v10 and v20 are used as prefixes with potentially browser-specific encryption procedures, while DPAPI refers to straightforward decryption as-is via Windows's Data Protection API

[2] v10 refers to a cookie encryption type; v10 is used as a prefix, with a key retrieved from Keychain

Elevation for Decryption

v20 cookies on Windows Chromium browsers go through the System account for encryption, and decryption requires a process to run under that account for the right DPAPI context. A helper Windows PowerShell (not PowerShell Core) script is embedded in this library which includes the Invoke-CommandAs library and a small job which will ultimately execute a decryption via the System account. Getting the job scheduled requires elevation to administrator, so the PowerShell process that runs the helper script is elevated which will trigger a UAC prompt if those are enabled.

v10 cookies on macOS go through Keychain, specifically via the security CLI which accesses the browser's store in Keychain. This will trigger a privilege check with an option to always allow the calling program access to that store. Do not select Always Allow, as the permissions are being granted to the security utility.
