Bitget Detects Unauthorized Transfers
According to Bitget's official security notice, its security systems detected unauthorized transfers from some hot wallets at 18:31 UTC on September 24.
The exchange said its security team activated emergency response protocols immediately after detecting the activity.
Bitget has described the incident as affecting part of its hot and warm wallet layers within its three-tier wallet architecture.
Approximately $351.6 Million in Funds Affected
Bitget estimates that approximately $351.6 million in funds were affected by the incident.
The exchange said its cold wallets remain fully secure.
Bitget also stated that the affected loss falls within the coverage of its User Protection Fund, which it said held more than $464 million at the time of its security notice.
Withdrawals Temporarily Suspended
Bitget temporarily suspended cryptocurrency withdrawals as a precaution while its security team conducts a review.
The security notice said withdrawals were temporarily unavailable following the September 24 incident.
Deposits and trading remained fully operational.
Bitget said withdrawals would be restored once the security review is complete.
Bitget Says User Funds Remain Safe
The exchange said customer account balances remain accurate and that user assets are protected.
Bitget also said the loss associated with the platform-wide incident is covered by its User Protection Fund.
The company emphasized that the withdrawal suspension was a security precaution rather than an indication of a shortfall in customer funds.
Cold Wallets Remain Secure
Bitget operates a three-tier wallet architecture covering hot, warm and cold wallet layers.
According to the company's official notice, the incident affected only a portion of the hot and warm wallet layers.
Bitget said its cold wallets remained fully secure.
This distinction is important because the exchange has not described the incident as affecting all of its wallet infrastructure.
Authorities and Security Firms Notified
Bitget said abnormal transfer addresses were identified, flagged and reported following the incident.
The exchange also said relevant authorities and on-chain security firms had been formally notified and were engaged in the response.
Bitget has not publicly identified the individuals or group responsible for the unauthorized transfers in its official security notice.
Investigation Into the Incident Continues
Bitget said it will provide updates as its investigation progresses.
The exchange also stated that it would not speculate about the attack vector until the investigation is complete.
The company said updates would be posted through its official channels as they become available.
This means details about how the unauthorized transfers occurred remain subject to the ongoing investigation.
Deposits and Trading Continue
While withdrawals remain temporarily paused, Bitget says deposits and trading remain fully operational.
The exchange has instructed users to follow its official announcement channels for updates regarding the restoration of withdrawal services.
Bitget said users' account balances remain accurate and their assets are protected.
TwikUp's Perspective
The incident highlights the operational risks that cryptocurrency exchanges face when managing different layers of digital-asset custody.
Bitget's official statements provide an important distinction between the affected wallet layers and customer funds. The exchange says cold wallets remain secure and that its User Protection Fund covers the reported loss.
The suspension of withdrawals also shows why exchanges may temporarily restrict a specific service while investigating unusual blockchain activity.
However, the full technical explanation remains unavailable because Bitget says the investigation is ongoing and that it will not speculate about the attack vector.
For users and the wider crypto market, the most important developments to watch are the restoration of withdrawals and any corrective measures announced by Bitget.
What Happens Next?
Bitget says withdrawals will remain temporarily suspended while its security review continues.
The exchange is expected to provide further updates through its official channels after the review is complete.
Until the investigation is completed, the exact method behind the unauthorized transfers and the identity of those responsible have not been confirmed by Bitget.
