Google has launched a new Gmail tool that uses some clever auto-sleuthing to predict when your account has been hijacked and warn you about it before some illiterate crook can send all your friends emails saying that you've been arrested in Jamaica and need! cash! fast!
Keep in mind that these notifications are meant to alert you of suspicious activity but are not a replacement for account security best practices. If you'd like more information on account security, read these tips on keeping your information secure or visit the Google Online Security Blog.
Finally, we know that security is also a top priority for businesses and schools, and we look forward to offering this feature to Google Apps customers once we have gathered and incorporated their feedback.
