The attacker did not access the wallet for years — simply waited. Once large sums appeared on the address, the hacker executed a single operation and took all the USDC tokens. Such incidents highlight the importance of regularly reviewing permissions and revoking accesses no longer in use.
This case underscores the critical need for careful management of digital asset security and may prompt the development of improved standards to protect crypto wallets.
