A former Microsoft software engineer was convicted of 18 federal felonies related to his scheme to defraud Microsoft of more than $10 million and then file fake tax return forms.

Vlodymyr Kvashuk, 25, a Ukrainian citizen residing in Renton, Washington, worked first as a contractor at Microsoft and then as an employee from August 2016 until he was fired in June 2018.

According to trial evidence, Kvashuk stole “currency stored value,” such as digital gift cards, from Microsoft.

In all, Kvashuk transferred approximately $2.8 million in bitcoin to his bank accounts. Kvashuk then filed fake tax return forms, claiming the bitcoin had been a gift from a relative.
