If you use Gmail, it might be worth a moment to check your settings to make sure that there are no malicious “forward” instructions there.

Although Google has now apparently patched the bug, it seems that for a time this vulnerability made it possible for hackers to insert instructions to forward some of your mail to them if you had the misfortune to visit a web page that had the right malicious code while you had gmail open in another tab or window..

Here’s an account of someone who says his business was sabotaged as a result.

Odds are high that you’re fine. But to confirm it, here’s what you do in after logging in to Gmail:

… click on the ’settings’ tab in the upper right of the screen. Then check both the ‘Filters’ and the ‘Forwarding and POP’ sections.

Examine what’s listed there to make sure there’s no forwarding instruction you didn’t put there yourself.
