A backup key took about $182,000 in crypto from a BitGo wallet tied to Unocoin. The first transfer came six minutes after the exchange said no funds were lost.
Unocoin has not named the wallet that was hit. We searched Ethereum for one that matches, tied it to one user's old Unocoin deposit, followed the money to four exits, and looked for the thief's keys on nine other chains.
2 of 3 Keys signed each payout. BitGo's key was frozen, so the user key and backup key signed all 98 theft transfers without it.
