An Ancaster man will be in a San Francisco court today for sentencing after pleading guilty to nine charges stemming from a massive hack of Yahoo email accounts.
Karim Baratov was arrested in his home last March.
He waived his extradiction hearing and was sent to the US to face charges of conspiracy to commit computer fraud and abuse and eights counts of aggravated identity theft.
American authorities allege Baratov was a hacker for hire and the data breach was ordered by Russian intelligence agents.
At least 500 million Yahoo user accounts were compromised.
