- Upbit hacked on merger day; Lazarus likely involved.
- $30.4 million stolen; full reimbursement promised.
- Increased security audits follow repeated breaches.
On November 28, Upbit, South Korea’s largest cryptocurrency exchange, suffered a significant hack linked to the Lazarus Group, resulting in a loss of approximately 44.5 billion KRW from its Solana network hot wallet.
The breach exemplifies persistent vulnerabilities in key management and network security, prompting increased scrutiny on South Korean exchanges amid rising threats from sophisticated hacking groups like Lazarus.
Lazarus Strikes on Day of Upbit’s Major Merger Announcement
The attack was identified soon after Dunamu, Upbit’s parent company, announced a merger with Naver’s fintech arm. Security firm GoPlus alerted about key management issues, observing similarities with Lazarus methods. Cold wallets remain secure, but the systemic vulnerabilities raised alarms across the industry. Oh Kyung-seok, CEO of Dunamu, confirmed swift action to halt transactions, with total reimbursement from company reserves.
This contrasts with other firms that delay such commitments, reflecting positively on customer trust retention.
