Sony employees forced to use old BlackBerry phones to deal with cyber attack

Washington: According to new reports, Sony employees had to resort to older technologies like the BlackBerry to keep the work going and used a phone tree to relay messages when the cyberattack on Sony Pictures was launched.

The employees relayed details about the hack from one person to another via phones and had to use ancient technology to issue physical checks since they couldn't transfer salaries through bank deposit.

Sony CEO Michael Lynton said that it took him more than 24 hours to realize the severity of the attack, reported CNN.

The company's entire computer system had been down during the week of Thanksgiving.

Employees also had to cut paychecks manually, use personal cellphones, Gmail accounts and notepads.
