Earlier this week, Google reported that hundreds of Gmail accounts were compromised as a result of phishing attacks against the site. It now appears that in addition to the Gmail attacks, attempts have been made to steal the login information of users of both Yahoo mail and Microsoft’s Hotmail service. While these attacks have happened in close proximity, it is currently believed that the Yahoo and Hotmail attacks were separately conducted from the Gmail attacks earlier this week. The goal of the attacks in the Google breach was to gain login information so the hackers could add their own email addresses to the forwarding settings. It’s not clear at this point how many accounts on either service have been compromised, if any, but if you use either of these services it might be a good idea to change your password and check your forwarding settings.
