Indodax, leading cryptocurrency exchange in Indonesia, suffered a significant loss estimated at approximately $20.5 million due to a major cyber attack. The incident was detected by the leading blockchain security firm Cyvers, which identified suspicious activity involving large asset transfers and significant losses.
Details of the Attack
The blockchain security firm Cyvers detected suspicious activity when 660 ETH was transferred from Indodax’s hot wallet, prompting an immediate investigation. Over 160 critical red flags were raised during the attack, indicating multiple asset chain breaches and rapid fund transfers. The incident affected multiple blockchains and is suspected to be linked to North Korea's notorious Lazarus Group. Yosi Hammer, Head of Ai at Cyvers, stated: 'While it is premature to confirm the involvement of any specific group, the attack’s speed and complexity, as well as its characteristics, highly resemble those of North Korea’s Lazarus Group.' The Lazarus Group has been linked to some of the largest cyber thefts in the crypto space, utilizing a variety of techniques to exploit vulnerabilities in exchange systems. Their signature methods include rapid asset transfers, access control violations, and multiple swaps across different chains—all of which were present in the Indodax exploit.
Indodax's Response
Indodax responded to the attack by temporarily shutting down its platform for maintenance and assured users that both crypto and rupiah funds were safe. In a statement on X (formerly Twitter), Indodax announced: 'We have identified a potential security issue and are conducting complete maintenance to ensure the safety of our platform. Your balances remain secure.' Despite assurances about the safety of client funds, the exchange has not yet provided further details about how the breach occurred or the measures being taken to prevent future incidents.
Previous Security Challenges for Indodax
This is not the first time Indodax has faced security-related issues. In June 2023, Indonesian authorities arrested two fraudsters who impersonated Indodax on fake social media accounts, offering fake investment opportunities and stealing around 625 million Indonesian Rupiah (approximately $40,500). While this incident was unrelated to the current exploit, it underscores the security challenges faced by the exchange.
The Indodax breach is just one in a series of high-profile crypto attacks this year. The rise in cybercrime within the crypto industry requires increased security measures and more diligent protection of systems from all market participants.
