A former Microsoft software engineer has been sentenced to nine years in prison for digital gift card theft from the tech giant valued at more than 10 million dollars.

Volodymyr Kvashuk was able to disguise the evidence by using a bitcoin mixing service before the funds were deposited into his accounts. He stole $12,000 in value using his own account access before switching to email accounts belonging to other Microsoft employees. This cast suspicion on several others, with Kvashuk feigning innocence and incriminating co-workers before a jury found him guilty of all counts.

In a period of seven months, over two million in bitcoin was transferred to his bank and investment accounts, and on his tax return he claimed the bitcoin was a gift from a relative. Kvashuk used a portion of the stolen funds to purchase a lakefront home and a luxury car.

He was ordered to pay over eight million dollars in restitution and may be deported back to the Ukraine after serving the prison term.
