Imagine waking up to find your digital wallet—your lifeline to millions in crypto—completely drained. That’s the nightmare Radiant Capital faced in October 2024, when a hacker siphoned $53 million from their decentralized finance (DeFi) protocol. But here’s the kicker: the thief didn’t just vanish with the loot. Through a series of calculated Ethereum trades, they nearly doubled their haul to $94 million. How does someone pull off such a stunt in the wild west of blockchain? Let’s unravel this high-stakes drama and explore what it means for the future of crypto security.
The Radiant Capital Heist: A Digital Disaster
The crypto world is no stranger to hacks, but the Radiant Capital breach hit like a thunderbolt. This wasn’t a random smash-and-grab; it was a meticulously planned assault on a multisig wallet, a supposedly secure setup requiring multiple approvals for transactions. The attacker exploited a vulnerability using macOS-specific malware, later identified as INLETDRIFT, to compromise the core team’s defenses. Within hours, they’d drained lending pools on Arbitrum and BNB Chain, converting the stolen assets into 21,957 ETH—worth about $53 million at the time.
What makes this story wild isn’t just the theft but what happened next. Instead of cashing out and disappearing, the hacker played the market like a Wall Street pro. By holding onto Ethereum during its price surge and making strategic trades, they turned their ill-gotten gains into a staggering $94.63 million. It’s the kind of move that leaves you wondering: is this a criminal mastermind or just someone with a knack for timing?
How the Hacker Doubled Their Loot
The hacker’s playbook reads like a crypto trader’s dream. According to blockchain analysts, they sold 9,631 ETH at an average price of $4,562, pocketing 43.9 million DAI, a stablecoin pegged to the dollar. When Ethereum’s price dipped to $4,096, they swooped back in, buying 2,109.5 ETH for $8.64 million DAI. This left their wallet with 14,436 ETH and 35.29 million DAI—a portfolio now valued at nearly $95 million. Talk about playing the market!
The decision to hold ETH during its rally was a game-changer. Most hackers liquidate fast, but this one played the long game.

The brilliance—or audacity—lies in their timing. Ethereum’s price volatility is no secret, yet this hacker rode the waves with precision. By keeping most of their assets in ETH during a bullish run, they capitalized on a market upswing that many legitimate traders would envy. It’s a stark reminder that blockchain transparency cuts both ways: while it allows analysts to track every move, it also gives savvy criminals room to maneuver.
The Malware Menace: How They Got In
The attack’s entry point was as chilling as it was sophisticated. The hacker deployed INLETDRIFT, a macOS-targeted malware, to infiltrate Radiant Capital’s multisig wallet. This wasn’t a brute-force hack but a social engineering coup, likely tricking a team member into downloading malicious software. Once inside, the attacker had free rein to drain funds from lending pools across two blockchains.
Security experts suspect this wasn’t a lone wolf but part of a coordinated effort tied to North Korea’s AppleJeus group, notorious for targeting crypto platforms. Their playbook? Exploit human error, bypass technical safeguards, and disappear into the digital ether. For Radiant Capital, it was a brutal lesson in the risks of centralized control within a supposedly decentralized system.
- Multisig wallet vulnerability: Required multiple approvals but fell to malware.
- Malware sophistication: Tailored for macOS, likely via phishing or fake software updates.
- Cross-chain attack: Hit lending pools on Arbitrum and BNB Chain simultaneously.
I’ve always found it ironic that DeFi, built on the promise of trustless systems, often hinges on human trust. One wrong click, and millions vanish. It’s a humbling reminder that even the most secure tech is only as strong as its weakest link.
Why Recovery Is a Long Shot
Once the funds were gone, Radiant Capital didn’t sit idle. They enlisted the FBI, blockchain analytics firms, and Web3 security teams to track the stolen assets. But here’s the harsh reality: recovering crypto after a hack is like chasing a ghost. The funds, now spread across Ethereum wallets and converted into stablecoins, are nearly impossible to claw back without the hacker’s cooperation.
Crypto’s decentralized nature is a double-edged sword. It empowers users but also shields criminals.

The hacker’s ongoing trades show they’re not done yet. Every transaction is traceable on the blockchain, yet that transparency hasn’t led to recovery. Why? Because mixers, privacy coins, and cross-chain swaps make it easy to obscure funds. Add to that the suspected involvement of a state-backed group, and the odds of retrieving the $94 million dwindle further.
DeFi’s Persistent Security Woes
Radiant Capital’s breach wasn’t an isolated incident. In 2024 alone, DeFi protocols lost hundreds of millions to exploits, from flash loan attacks to smart contract bugs. Radiant itself suffered a $4.5 million flash loan hack earlier that year, making the October heist their second major blow. It’s a pattern that’s hard to ignore: DeFi’s innovation comes with a steep security cost.
| DeFi Hack | Loss Amount | Attack Type |
| Radiant Capital (Oct 2024) | $53M | Multisig Malware |
| Radiant Capital (Earlier 2024) | $4.5M | Flash Loan |
| Other Major Protocol | $48M | Exchange Breach |
What’s frustrating is how preventable some of these attacks seem. Multisig wallets are designed for security, but they’re useless if a single keyholder falls for a phishing scam. Perhaps the most sobering lesson is that human error remains the biggest threat to DeFi’s promise of financial freedom.
What’s Next for the Hacker?
The hacker’s wallet is now a ticking time bomb under the watchful eyes of analysts. Will they cash out and disappear, or keep trading to grow their stash? Their ability to navigate Ethereum’s volatility suggests they’re not in a rush. But with every move tracked on the blockchain, they’re walking a tightrope.
Some speculate they’ll use mixers to launder the funds, while others think they’ll hold ETH for another rally. Either way, their success highlights a grim truth: in crypto, crime can pay—at least for now. It’s a cat-and-mouse game, with security teams racing to outsmart an enemy who’s always one step ahead.
Lessons for Crypto Investors
So, what can you take away from this saga? For starters, DeFi isn’t the Wild West for nothing. The freedom to control your assets comes with the responsibility to protect them. Here’s how to stay safe:
- Verify wallet security: Use hardware wallets or trusted multisig setups.
- Beware of phishing: Never click suspicious links or download unverified software.
- Spread your risk: Don’t keep all your assets in one protocol or wallet.
- Stay informed: Follow blockchain analytics to spot suspicious activity early.
In my experience, the crypto space rewards those who stay vigilant. It’s not just about chasing gains but protecting what you’ve got. The Radiant Capital hack is a wake-up call: no one’s coming to save your funds if you slip up.
The Bigger Picture: Can DeFi Stay Safe?
The Radiant Capital heist isn’t just a story about one hacker’s windfall; it’s a red flag for the entire DeFi ecosystem. As protocols scale, so do the stakes. A single breach can wipe out millions, erode trust, and invite regulatory scrutiny. Yet, the allure of decentralized finance—freedom from banks, control over your money—keeps users coming back.
DeFi’s promise is real, but its vulnerabilities are just as real. Security must evolve faster than the hackers.

Maybe the most intriguing aspect is how this incident exposes the paradox of blockchain. It’s transparent yet anonymous, empowering yet perilous. For DeFi to thrive, developers need to prioritize robust security—from smarter wallet designs to better user education. Until then, stories like Radiant Capital’s will keep making headlines.
As I reflect on this, I can’t help but wonder: will DeFi ever outgrow its growing pains? The tech is revolutionary, but the risks are real. For now, the hacker’s $94 million stash is a stark reminder that in the crypto world, fortune favors the bold—and sometimes, the unscrupulous.
