Radiant Capital Hacker Doubles Stolen Funds With 93.5% Gain in ETH
Kuala Lumpur, 13 August 2025 — In a development that has sent shockwaves through the decentralized finance (DeFi) community, the hacker responsible for the recent Radiant Capital exploit has managed to almost double their stolen funds by riding Ethereum’s price rally. Blockchain data shows that the attacker’s ETH holdings surged 93.5% in value over the past two weeks.
The Exploit That Started It All
Radiant Capital, a cross-chain lending protocol, suffered a critical security breach in late July 2025. According to on-chain analysis from blockchain security firm PeckShield, the attacker exploited a smart contract vulnerability, siphoning an estimated $3.5 million worth of digital assets, primarily in Ethereum (ETH) and stablecoins.
Following the attack, the stolen funds were quickly laundered through a series of tornado mixers and cross-chain bridges, making real-time tracking challenging for investigators.
How the Hacker Turned $3.5M into Over $6.7M
In the days after the exploit, the attacker consolidated most of the stolen ETH into a single wallet. Ethereum’s subsequent rally — driven by US macroeconomic data, growing ETF speculation, and heightened DeFi activity — saw prices climb sharply. This market move inflated the hacker’s ETH position by nearly 93.5%, bringing the total value to over $6.7 million at current market rates.
“It’s a reminder that time often works in favor of attackers if stolen assets remain in volatile, appreciating cryptocurrencies,” said Tom Robinson, Chief Scientist at Elliptic.
Community Reaction and Security Lessons
The Radiant Capital team responded quickly after the breach, suspending affected markets, patching vulnerabilities, and initiating a post-mortem. However, the growing value of the stolen funds has left investors increasingly frustrated.
Prominent DeFi developers have called for:
- Real-time vulnerability audits before deploying major upgrades
- Protocol-level kill switches to limit losses in live hacks
- Insurance pools to protect liquidity providers in such incidents
Wider Impact on DeFi and Regulation
This incident underscores ongoing security challenges in DeFi. With over $1.6 billion stolen in crypto-related hacks in 2024, according to Chainalysis, regulators in the US, EU, and Asia-Pacific are intensifying their focus on smart contract audit requirements and AML/KYC obligations for DeFi protocols.
The case also highlights a regulatory blind spot: once illicit funds are held in crypto and the market rallies, law enforcement often faces additional hurdles in asset recovery.
