Got a hacked Yahoo account? Here's what you should do

Yahoo has announced another huge security breach, leaving its users fretting once again about their personal information.

The latest data theft affected more than one billion accounts, Yahoo (YHOO, Tech30) says. That's roughly double the number involved in the cybersecurity incident it announced in September, which is believed to be separate.

The embattled tech company said it's notifying users who may have been affected by the breach and making them change their passwords. The problem is it happened all the way back in August 2013.

That means whoever plundered the information has had more than three years to exploit it, security experts say.

SAN FRANCISCO--Yahoo, already reeling from its September disclosure that 500 million user accounts had been hacked in 2014, disclosed Wednesday that a different attack in 2013 compromised more than 1 billion accounts.

The two attacks are the largest known security breaches of one company’s computer network.

The newly disclosed 2013 attack involved sensitive user information, including names, telephone numbers, dates of birth, encrypted passwords and unencrypted security questions that could be used to reset a password. Yahoo said it is forcing all of the affected users to change their passwords and it is invalidating unencrypted security questions--steps that it declined to take in September.

Yahoo said it discovered the larger hacking after analyzing data files, provided by law enforcement, that an unnamed third party had claimed contained Yahoo information.

Security has taken a back seat at Yahoo in recent years, compared to Silicon Valley competitors like Google and Facebook. Yahoo’s security team clashed with top executives, including the chief executive, Marissa Mayer, over the cost and customer inconvenience of proposed security measures.

And critics say the company was slow to adopt aggressive security measures, even after a breach of over 450,000 accounts in 2012 and series of spam attacks--a mass mailing of unwanted messages--the following year.
