Radiant Capital Hacker Turns $53 Million Heist Into $95 Million

• Radiant Capital Hacker Increases Stolen Funds with Ethereum
• Profits surge to 56% after strategic ETH trading
• Criminal controls 17 ETH and $25 million in DAI

The hacker responsible for the attack on the Radiant Capital protocol in October 2024 was able to significantly increase his profits by adopting a smart trading strategy with Ethereum (ETH). The attack, which affected BNB Chain and Arbitrum, initially resulted in the theft of approximately $53 million in digital assets.

According to on-chain analysts, the attacker compromised developers' hardware wallets, taking control of tokens such as WETH, WBTC, USDC, USDT, and Arbitrum, which were later consolidated onto the Ethereum network.

According to analyst EmberCN, on August 20th, the hacker began liquidating part of the ETH they had obtained. 9.631 ETH were sold at an average price of $4.562, raising approximately $43,94 million in DAI. The operation occurred during a period of ETH appreciation, which was once again approaching its all-time high of $5.000.

啊，好家伙，这 Radiant Capital 黑客竟然玩起波段来了😂：
$4,562 for $9,631 for $4393.7 for DAI for $XNUMX for DAI.
这几天 ETH 回调了，他在过去 1 小时里又用 $864 万 DAI 以 $4,096 的价格重新买回了 2109.5 枚 ETH…

However, the attacker also took advantage of the asset's recent drop to buy back. In a single transaction, he reacquired 2.109,5 ETH for approximately $8,64 million in DAI, paying an average price of $4.096 per coin.

This strategy of selling high and buying low allowed the hacker to reduce his exposure to market fluctuations while simultaneously expanding his ETH position. As a result, he currently controls approximately 17.000 ETH and $25,29 million in DAI, totaling approximately $96 million in assets, according to data from Arkham Intelligence.

The increase represents a 56% increase over the original amount stolen, equating to over $42 million in additional earnings.

The Radiant Capital case remains one of the most notorious attacks against DeFi protocols in recent years, not only due to the magnitude of the initial theft, but also due to the hacker's ability to leverage the funds through strategic trading in the cryptocurrency market.
