Chrome Version: 55.0.2883.95
OS: Mac OS X
While browsing the web, a friend visited a site that redirected them to a page on
http://mithai.ga. This caused several bad things to happen:
- A JS alert dialog popped up claiming the computer was infected with viruses
- The tab could not be closed (presumably because of the JS alert window?)
- The user could not quit Chrome -- see second attached screenshot. The Quit menu item is grayed out and "Warn before quitting" is shown.
What steps will reproduce the problem?
(1) Visit http://mergeboutique.com
(2) Get redirected to http://mithai.ga/5764/c/your-computer-is-locked-call-us-at-tollfreenow--1-888-403-6867-your-computer-is-locked-call-us-at-tollfreenow--1-888-403-6867
(note - this does not always happen, probably depends on a specific ad being shown on the original page).
The bug is simply that a web page should never be able to hijack Chrome in this way.
