Google will deploy a new security feature in Chrome next year to prevent tab-nabbing, a type of web attack that allows newly opened tabs to hijack the original tab from where they were opened. From a report: The new feature is scheduled to go live with Chrome 88, to be released in January 2021. While the term “tab-nabbing” refers to a broad class of tab hijacking attacks [see OWASP, Wikipedia], Google is addressing a particular scenario. This scenario refers to situations when users click on a link, and the link opens in a new tab (via the “target=_blank” attribute). These new tabs have access to the original page that opened the new link. Via the JavaScript “window.opener” function, the newly opened tabs can modify the original page and redirect users to malicious sites. This type of attack has powered quite a few phishing campaigns across the years. To mitigate this threat, browser makers like Apple, Google, and Mozilla have created the rel=”noopener” attribute.
