MoscowHackers reportedly stole hundreds of millions of Dodo Pizza orders.
A Moscow court placed Denis Fridman, 19, under house arrest until 8 December.
Police reportedly traced him to Barnaul after he exposed his internet address while accessing the stolen data.
ATB, Ukraine’s largest grocer, denies losing customer data, though DataSuckers claimed 7.9 million records.
A fourth alleged member remains at large, and the suspects include citizens of Kazakhstan and Belarus.
