Don't Let Tab-Nappers Catch You Napping

Dubbed tab-napping, a new type of attack has been using Java script to secretly change the content of open, but idle, tabbed browser windows.

Even hours after opening them, users may see familiar-looking log-in windows for their online shopping or e-mail accounts. But, credential information used to log-on may actually be sent to hackers. Analysts caution, all of the major browsers for Windows 7 and Mac Operating Systems are potentially vulnerable.
