Computer system security can be threatened by users who manipulate their software to avoid detection of malicious activities—such as account takeover. Web browser software, for example, can be altered so the browser will report false information about the browser itself and/or the system on which it is running. By providing such false information, a user can try to avoid his system being fingerprinted (e.g. identified) so that the user can more effectively instigate electronic attacks without being detected. This disclosure describes techniques that allow for detection of when a user has tampered with their web browser (e.g., by overriding native code functions in the browser). Detecting that a browser has been tampered with can allow a computer server system to take mitigation actions against potentially malicious users, thus improving computer security.
