Oh Kyoung-suk, CEO of Dunamu, issued an official apology over the hacking incident at Upbit that involved 44.5 billion won.
Oh said in a statement on the 28th that "of the 44.5 billion won in hacked asset, about 2.3 billion won of member asset has been frozen," adding, "We deeply apologize for causing concern to our members due to the cyber intrusion incident."
There is no excuse for inadequate security management at Upbit, he said, adding, We have reported the incident to the relevant authorities under applicable laws and are investigating the cause and scope of the incident.
On the morning of the 27th, when unusual withdrawals were detected from a Solana-based wallet, Upbit conducted a comprehensive inspection of the related network and wallet systems and blocked deposits and withdrawals.
Oh said, We analyzed multiple Upbit wallets disclosed on the Blockchain, found security vulnerabilities, and took action, adding, We are tracking digital asset that moved outside Upbit and implementing freezing measures.
Upbit is currently overhauling its wallet system and plans to resume virtual asset deposits and withdrawals once stability is secured.
Oh said, We will cooperate closely with the relevant authorities and provide transparent guidance on matters that can be disclosed, adding, We have activated a companywide emergency response system and are reviewing the entire security system in connection with this intrusion incident.
He added, We will fully compensate user asset with Upbit asset, and We will do our utmost to establish measures to prevent a recurrence, including advancing the security system.
