Rumors have been circulating on the intarwebs about a sudden increase in hacked Gmail accounts for the last few days, and it now looks like it's confirmed.
Robert McMillan from PC World reports in that "Google is investigating a growing number of reports that hackers are breaking into legitimate Gmail accounts and then using them to send spam messages. The problem started about a week ago but seems to have escalated over the past few days."
Google insists that there is no Gmail bug, but they did make a page available that helps you check to see if your Gmail account may have been used by someone other than you. Those of you who use a Gmail account may want to take a peek and see if anything looks suspicious.
