In October 2024, Radiant Capital, a decentralized finance (DeFi) platform, fell victim to a significant hack that siphoned off $50 million. Investigations revealed that the attack originated from a group believed to be aligned with North Korea. The exploitation of the platform was primarily facilitated through advanced malware distributed via Telegram, underscoring the importance of cybersecurity hygiene in an increasingly complex digital landscape.
The hacking scheme commenced on September 11, 2024, when a developer at Radiant received a seemingly innocuous message from an individual impersonating a former contractor. This tactic of impersonation highlights a disturbing trend in cybersecurity attacks—social engineering. The message requested feedback on a PDF file related to smart contract auditing, prompting the developer to download it. However, the file, deceptively named Penpie_Hacking_Analysis_Report.zip, concealed a macOS backdoor malware called INLETDRIFT.
Upon activation, this malware established communication with an external server while masquerading as a legitimate PDF document. The attackers adeptly manipulated the appearance of the file to avoid suspicion, effectively bypassing Radiant’s robust security protocols that typically safeguard against malicious activity.
Radiant Capital reacted swiftly to the breach by enlisting the help of cybersecurity firms—including Mandiant, zeroShadow, Hypernative, and SEAL 911—aimed at investigating the fallout and strengthening their defenses against future breaches. Despite existing security measures like transaction simulations and payload verifications, the malware’s sophisticated delivery mechanism allowed it to deceive developers into approving malicious transactions masquerading as valid operations. This betrayal of trust among users and developers encapsulates the necessity of continually evolving security frameworks to combat increasingly crafty attackers.
According to zeroShadow, a firm specializing in Web3 security solutions, there is a high level of confidence in attributing the attack to actors aligned with North Korea. This attribution was supported by a multitude of indicators, both on-chain and off-chain, adding credence to the severity of the threat posed by state-sponsored hacking initiatives. Notably, the investigation revealed that the movement of funds through Hyperliquid stemmed from Radiant users’ failure to revoke permissions tied to the hack rather than direct theft from the initial exploit.
The incident is not Radiant Capital’s first brush with significant security issues. Earlier in January 2024, a smart contract vulnerability resulted in a loss of $4.5 million, showcasing that this is an organization that has struggled to maintain security integrity. As of the time of the October hack, the platform’s total value locked (TVL) had plummeted from a high of over $300 million earlier in the year to just over $6 million. This downturn illustrates the fragile nature of user confidence in DeFi operations when security lapses become public, especially in an era where decentralized finance has garnered both immense interest and considerable scrutiny.
The October 2024 hack of Radiant Capital serves as a critical reminder of the vulnerabilities that exist within the decentralized finance sector. It highlights the pressing need for enhanced cybersecurity practices, rigorous training in identifying social engineering attempts, and the importance of maintaining robust user permissions. As the DeFi landscape continues to evolve, so too must the strategies to defend against an ever-deepening abyss of cybersecurity threats.
