Description Huzaifa S. Sidhpurwala 2014-03-17 03:00:54 UTC 
Security researchers Tim Philipp Schäfers and Sebastian Neef, the team of Internetwache.org, reported a mechanism using JavaScript onbeforeunload events with page navigation to prevent users from closing a malicious page's tab and causing the browser to become unresponsive. This allows for a denial of service (DOS) attack due to resource consumption and blocks the ability of users to exit the application.
