ChromeLogger is a keylogger and form grabber that runs as a Google Chrome extension. Since it’s a Chrome addon, it’s compatible with the latest version of Chrome on all OS’s (Windows, Mac, Linux).

ChromeLogger will save all keystrokes typed into webpages that are opened by Chrome. There’s also an option to capture form submissions (ie, search boxes, login forms). After installing, ChromeLogger will be completely silent and will automatically start recording keylogs.

ChromeLogger works by injecting javascript into all loaded web pages. The payload records keypresses using event listeners and saves them to Chrome’s storage. Unlike other browser keyloggers, ChromeLogger runs natively in Chrome (on all OS’s) without the need to install additional software.  The form grabber works in a similar way. Javascript is injected and event listeners are added for all forms. When a form is submitted, its data is saved to ChromeLogger’s storage. This allows form data transferred over SSL to be saved in plaintext.
