You might need to change your email password in the very near future. A member at a Russian Bitcoin forum has posted almost 5 million Gmail passwords, around 60 percent of which are reportedly still working. It's not clear how the poster managed to scoop up all this account info, but Google tells Cnews that it comes from a long stretch of hacking and phishing attempts that stole data from individual users. Gmail's servers weren't breached, the search giant says, and much of what's there is old. That's somewhat comforting, but you may want to check if your account is one of the unfortunate targets -- you don't want to give thieves easy access to your most sensitive info.
