Chrome was the industry's first major web browser to adopt site isolation as a defense against uXSS and transient execution attacks. [34] To do this, they overcame multiple performance and compatibility hurdles, and in doing so, they kickstarted an industry-wide effort to improve browser security .
The Chromium code of Google Chrome is continuously fuzzed by the Chrome Security Team with 15,000 cores. [46] For Microsoft Edge and Internet Explorer, Microsoft performed fuzzed testing with 670 machine-years during product development, generating more than 400 billion DOM manipulations from 1 billion HTML files.

No hack attempts were made against Chrome, [21] [104] although the reward offered was the same as for Edge. [105] Hackers were ultimately awarded $267,000. [ 103 ] While many Microsoft products had large rewards available to anyone who was able to gain access through them, only Edge was successfully exploited, and also Safari and Firefox.
The big advantage of these types of tools are that they can scan year-round to be constantly searching for vulnerabilities. With new vulnerabilities being discovered regularly this allows companies to find and patch vulnerabilities before they can become exploited. [3] As a dynamic testing tool, web scanners are not language-dependent.
Exploits often use specific bytes to spray the heap, as the data stored on the heap serves multiple roles. During exploitation of a security issue, the application code can often be made to read an address from an arbitrary location in memory. This address is then used by the code as the address of a function to execute.
The Chromium code of Google Chrome is continuously fuzzed by the Chrome Security Team with 15,000 cores. [52] For Microsoft Edge [Legacy] and Internet Explorer , Microsoft performed fuzzed testing with 670 machine-years during product development, generating more than 400 billion DOM manipulations from 1 billion HTML files.
Cross-site scripting (XSS) [a] is a type of security vulnerability that can be found in some web applications. XSS attacks enable attackers to inject client-side scripts into web pages viewed by other users. A cross-site scripting vulnerability may be used by attackers to bypass access controls such as the same-origin policy.
