The security bug was discovered by FireEye (FEYE) and allows hackers to take over a person’s computer if the visit a certain website. Once the computer is taken over, hackers can look into people’s emails and other private files. The hack works by exploiting a bug in the Adobe Flash plugin. Disabling the plugin can stop the hack, reports CNN Money.
“On completion of this investigation, Microsoft will take the appropriate action to protect our customers,” Microsoft told The Wall Street Journal.
Those using Internet Explorer have several options of web browsers to switch to until the bug is fixed. Google (GOOG) Chrome, Apple’s (AAPL) Safari and Mozilla Firefox are all good browsers to use in place of Internet Explorer.
This bug will be doubly bad for those using Internet Explorer on Windows XP. Microsoft no longer supports XP, which means that users of the operating system will never see an official security patch to defend against the bug, CNN Money notes.
