During May, more than 630 million credentials belonging to users of LinkedIn, MySpace, Fling, Vkontakte and Tumblr were released. Large data breaches at several large online services have put other services on edge.
Mass password resets run the risk of aggravating users but may be necessary in an emergency. Some companies do sophisticated monitoring of login attempts and lock accounts that appear to be specifically targeted. Online service providers generally do not take mass password resets lightly.
As a result, a hacker who has valid credentials could completely access someone's computer. GoToMyPC enables users to log in through a web service and remotely access another computer that has its application installed. "To protect you, the security team recommended that we reset all customer passwords immediately." "Unfortunately, the GoToMyPC service has been targeted by a very sophisticated password attack," according to a June 19 statement.
