Upbit, South Korea’s largest cryptocurrency exchange, removed all old deposit addresses as part of a major update to its wallet. Users must now create new deposit addresses before sending funds.
This update comes after a security breach on November 27, which caused losses of around 44.5 billion KRW (approximately $33 million). Because of this, Upbit is gradually reopening deposits and withdrawals for affected assets. The update is designed to protect users and restore trust in the platform.
Resumption of deposits and withdrawals
Starting December 5 at 17:00 KST, Upbit will gradually allow deposits and withdrawals of 33 crypto assets across 21 networks.
The exchange emphasized that users must generate new deposit addresses before making any transactions. Old addresses will no longer work. This step is necessary to keep funds safe and reduce the risk of further losses.
Upbit has been performing wallet maintenance and reviewing its security systems since the breach. Additionally, the update strengthens the protection of user assets and helps prevent future attacks.
Background: the November breach
On November 27, Upbit suffered a serious attack. Cybercriminals stole approximately 44.5 billion won. This affected multiple cryptocurrencies and shook confidence in the exchange.
Although Upbit froze certain operations and immediately launched an investigation, the incident shows that even large exchanges are vulnerable. Therefore, users should remain vigilant and follow security best practices when using centralized platforms.
Guidance for users
Upbit has provided clear instructions for its users:
- Generate new deposit addresses before making any transfers.
- Avoid using old deposit addresses for any transactions.
- Periodically monitor accounts and wallets for unusual activity.
Additionally, Upbit has increased customer support to help users adapt to the changes. Security experts recommend enabling two-factor authentication (2FA) and checking your accounts frequently to prevent unauthorized access.
Prevention of future violations
Upbit is also planning long-term improvements to strengthen its platform. New security measures include enhanced monitoring, advanced threat detection, and tighter internal controls. By taking these measures, Upbit hopes to reassure users and minimize the risk of future attacks while maintaining trust in its services.
Restore security and trust
Upbit’s wallet update shows the exchange’s commitment to protecting user funds. By requiring new directions and improving security, they aim to prevent future breaches.
As deposits and withdrawals gradually resume, the crypto community will be watching closely. Furthermore, this event highlights that security must remain a top priority in the rapidly growing world of cryptocurrencies.
