The FBI affidavit alleges Mr Aleynikov, after accepting the offer from his new firm – which has yet to be identified – downloaded approximately 32 megabytes of proprietary trading platform data from his desktop computer at work as well as his laptop at home on four separate occasions between June 1 and June 5, his last day at Goldman.

Despite that attempt, Goldman retains a back-up copy of each computer’s bash history.
