Chrome and Firefox have a serious security flaw, there is no way to fix it

This security flaw first appeared in February, and was later fixed by Google via an update to the Google Chrome browser. However, this security hole has recently reappeared on Chrome 67 and most likely has "evolved" to be harder to destroy than before.

According to Google Chrome, online fraudsters will use this bug to trick users into spending money to 'fix' system errors that do not exist. Mozilla's Firefox is also affected by a similar security vulnerability.

When encountering this bug, the victim will first see a fake warning screen about a system error. Then, the malicious code will trigger the browser to constantly save a file to the drive until it crashes. The whole process only takes 10 seconds to make users feel anxious. In addition, the warning message also has a phone number for users to contact through support but is actually the phone number of the bad person. When the user calls, the hacker will pretend to be a Microsoft software engineer and borrow the troubleshooting name to find out how to retrieve the user's bank account information.

Warning fake will have the same interface as in the picture above.

This fake warning often approaches users through hacked official websites or malicious code ads. The hacked programming interface is called window.navigator.msSaveOrOpenBlob.

While Chrome and Firefox are suffering from this vulnerability, it is surprising that Apple and Edge's Safari browsers are not affected at all.

Currently, Google is looking for ways to fix this vulnerability. Firefox is also rushing to investigate the incident.

If you encounter this warning, turn it off because it is just a very normal pop-up. If the browser has crashed many times, turn off the browser and press Ctrl + Shift + T to turn off the disabled tabs.

If you can't turn off the browser, press Ctrl + Alt + Delete to open the Task Manager management screen and turn off Chrome or Firefox there.

If Mac computers suffer from this vulnerability, press the combination Command + Alt + Esc then the Force Quit browser.

Currently, this vulnerability has only been exploited in the US, but users in Vietnam should still be cautious and alert.
