A Canadian young computer hacker who American investigators say unwittingly worked for Russian spies was sentenced to five years in prison Tuesday for his role in a massive security breach at Yahoo that U.S. federal agents say was directed by a Russian intelligence agency.
U.S. Judge Vince Chhabria also fined Karim Baratov $250,000 during a sentencing hearing in San Francisco.
Baratov, 23, pleaded guilty in November to nine felony hacking charges. He acknowledged in his plea agreement that he began hacking as a teen seven years ago and charged customers $100 per hack to access web-based emails. U.S. prosecutors allege he was “an international hacker for hire” who indiscriminately hacked for clients he did not know or vet, including dozens of jobs paid for by Russia’s Federal Security Service.
The breaches ranged in scope from two in 2012 where Yahoo said no data was taken, to a 2013 breach where hackers were able to gain access to all of the more than 3 billion Yahoo accounts and steal names, email addresses, telephone numbers, birth dates, passwords and answers to security questions. Yahoo said that if you had an account any time between Jan.1, 2012, and Dec. 31, 2016, and are a resident of the US or Israel, you are part of the settlement class and can file a claim for part of the $117,500,000 settlement fund https://money.cnn.com/2017/10/03/technology/business/yahoo-breach-3-billion-accounts/index.html
