Dana Tamir | February 05, 2014

The world’s second largest e-mail service, serving 273 million people worldwide, reported last week a breach into its users’ email accounts. In a blog posted by the company, Yahoo announced: "Recently, we identified a coordinated effort to gain unauthorized access to Yahoo Mail accounts." Yahoo did not disclose details of the attack but said, "the list of usernames and passwords that were used to execute the attack was likely collected from a third-party database compromise." Yahoo claims there is no evidence that the credentials were obtained directly from its own systems.
