Malware abuses Google OAuth endpoint to ‘revive’ cookies, hijack accounts
Multiple information-stealing malware families are abusing an undocumented Google OAuth endpoint named "MultiLogin" to restore expired authentication cookies and log into users' accounts, even if an account's password was reset.
Looks like another good reason not to ever use Chrome -- even on Mobile.
They seemed to have demonstrated it on chrome and leveraged by the chrome browser but I don't see why this couldn't be exploited on any browser.
Chromium is implied. Firefox isn't based on that code base unlike most every other browser.
