Airdrop Army

The DeFi universe keeps getting wrecked. This time, it’s Radiant Capital, the liquidity platform doing cross-chain deals, that faced a mega exploit. The crew behind this protocol says the breach is one of the “most sophisticated hacks ever recorded in DeFi.” Hackers walked away with a cool $50 million in tokens like USDT, USDC, ARB, and others, leaving a trail of drained pools and shattered wallets.

Attackers Breach Wallets, Drain Multiple Pools

Radiant’s platform got ripped apart in minutes. USDC, USDT, WETH, bBTC, WBTC—you name it, it was stolen. Around $16 million went poof from Radiant’s smart contract on the BNB Chain, and even more disappeared from their liquidity pools on Arbitrum. Hacken, the Web3 security audit squad, estimates the total damage at $50 million, but it might still climb higher as the dust settles.

It wasn’t just a smash-and-grab, though. This hack went deeper, targeting key developers’ wallets. Radiant claims the attackers managed to compromise at least three devs’ hardware wallets with malware, but it might’ve been more. Once the bad actors got in, they finessed their way through multiple layers of verification using “poisoned signatures.” These signatures tricked even the Safe{Wallet} multisig into approving transactions, letting the hackers move funds into their own wallets.

Radiant’s New Defense Plan After the Hit

After the hammer fell, Radiant rushed to put a patch on the gaping hole. They’re now working with U.S. law enforcement and ZeroShadow, a blockchain forensics team, to hunt down the stolen assets. Their new security measures? Every transaction will get double-checked on Etherscan to avoid any more fake signatures. And for all future upgrades or ownership transfers, they’ll enforce a minimum 72-hour delay, so devs have more time to review everything before it goes live.

But Radiant’s disaster isn’t the biggest loss in DeFi history. That crown still belongs to the Ronin Network hack from 2022, when $625 million in crypto got swiped. Nonetheless, Radiant’s breach shows how DeFi’s top players are still sitting ducks, no matter how sophisticated the tech seems.
