Yahoo also announced today that its proprietary code had been accessed by a hacker, who used the code to forge cookies that could be used to access accounts without a password. Yahoo employees reportedly knew of the intrusion that led to the theft of data from million users as early as , but the company did not announce the breach until this September. Yahoo did not disclose the first breach until several months after the deal was announced. Your Email required. You must register with Keepnet Labs to access this content.

So check the email affiliated with your Yahoo account if you haven't already. Yahoo has started sending out notifications to users, and you should be receiving one at that account if you were affected by the data breach. If you haven't changed your password in a few years, do it -- now. The company says the passwords that hackers stole were encrypted -- scrambled up with a tool called bcrypt.
This kind of encryption can potentially be broken with enough persistence, said Brett McDowell, executive director of the FIDO Alliance, a nonprofit group that vets login systems. That's especially true "when the attacker can make relatively accurate guesses at what the password might be," McDowell said. It's a common habit. Use the same password for lots of different accounts. If this breach has anything to teach you, it's that this is a terrible idea.
If you recycled your Yahoo password on a different account, go change your password on that account too. The hackers who have your password could easily try it on a whole bunch of different websites -- think bank websites or health insurance websites -- to try to access information beyond your Yahoo account. Since the hack exposed security questions that were not encrypted, change them. If you used the same security questions for other sites or services, change those, too.
