A security breach occurred at the cryptocurrency exchange Praben due to unauthorized access by an external party. The incident came to light when abnormal asset withdrawals were confirmed from the exchange's hot wallet, with damages identified so far amounting to approximately 100 million won. Praben has temporarily suspended its services and announced that it will fully compensate the damaged assets with its own funds.

■ Abnormal Withdrawals from Hot Wallet... "Unauthorized External Access Around the 24th"

Through an apology issued to its members, Praben stated that the breach occurred around the 24th due to unauthorized external access. The company reported the incident to the relevant authorities and is investigating the specific cause and extent of the damage.

A hot wallet is a wallet that stores cryptocurrencies while connected to the internet and is used for transactions, handling deposits and withdrawals. Upon detecting signs of abnormal withdrawals, Praben immediately activated an emergency response system and began inspecting the entire exchange system. During this process, security vulnerabilities were discovered, and the company temporarily suspended service operations to block the possibility of further damage and protect user assets.

■ Damages Amount to About 100 Million Won... "Full Compensation with Company Funds"

The scale of damaged assets identified by Praben so far is approximately 100 million won. However, as the investigation into the cause and scope of the incident is still ongoing, the final damage scale requires further confirmation.

The company stated that it will compensate users for their losses with its own assets. Praben explained that it plans to accurately calculate the damaged assets and then implement measures to fully compensate them using company funds. Accordingly, how the asset scale of affected members will be finalized, and when the compensation procedures and payment schedule will be specified, are expected to emerge as key points of interest going forward.

■ What Remains Unknown... From Intrusion Route to Service Resumption Timing

This incident once again highlights the importance of security in cryptocurrency exchanges' asset custody and deposit-withdrawal management systems. In particular, it has been reconfirmed that while hot wallets connected to the internet are used for trading convenience and prompt deposit-withdrawal processing, access controls and abnormal transaction detection systems against external intrusions are critical.

Based solely on what has been disclosed so far, it has not been specifically confirmed how the unauthorized external party accessed the system, or what impact the discovered security vulnerabilities had on the actual asset leakage. The types and quantities of cryptocurrencies damaged, the scope of wallets from which withdrawals were made at the time of the incident, and the timing of service resumption have also not been specified.

Praben stated that it plans to address the vulnerabilities identified after the incident, strengthen its overall security system, and pursue system upgrades and recurrence prevention measures. It also apologized for the inconvenience and concern caused to users by this breach and conveyed its intention to carry out security improvement work to build a safe trading environment. The company stated that any matters confirmed or changed during further investigations will be communicated to members.

Going forward, the results of the authorities' investigation, the procedures for compensating damaged assets, and the schedule for normalizing services are expected to be the major follow-up issues of this incident.
