#VIRTUALWhale
The platform was doing a normal transfer between its wallets
One of these wallets was MultiSig (a wallet that requires more than one signature to complete the transaction)
The hacker was able to exploit a loophole in one of the transactions that made the platform transfer him $401,346 ETH
Unfortunately @benbybit, the founder of Bybit, was the last one to sign the transaction and was unable to discover the loophole
