Imagine waking up to find your digital wallet, painstakingly built over years, drained by a faceless thief halfway across the globe. That’s the harsh reality Radiant Capital faced in October 2024, when hackers siphoned off $53 million from their lending pool. Fast forward a year, and the culprits have now funneled $10.8 million of that loot through Tornado Cash, a crypto mixer designed to obscure the trail of digital funds. This isn’t just a story about a heist—it’s a wake-up call about the vulnerabilities lurking in the decentralized finance world.
The Radiant Capital Heist: A $53M Nightmare
Last October, Radiant Capital, a prominent player in the DeFi space, suffered a devastating blow. Hackers exploited a flaw in the platform’s lending pool, making off with $53 million in assets from the Arbitrum (ARB) and Binance Smart Chain (BSC) networks. The breach wasn’t a brute-force attack but a cunning manipulation of the platform’s multi-signature wallets. By seizing control of three out of eleven signer permissions, the attackers replaced the lending pool’s implementation contract, redirecting funds to their own wallets.
What made this hack particularly chilling was the method. Investigators later uncovered that the perpetrators used a sophisticated malware called INLETDRIFT, tailored to infiltrate macOS systems. This wasn’t a random act of cyber vandalism—it was a calculated strike, likely orchestrated by a group with serious resources. I’ve always found it unsettling how quickly technology can turn from a tool of empowerment to a weapon in the wrong hands.
Crypto platforms are only as strong as their weakest link, and hackers are relentless in finding it.

From $53M to $94M: How Hackers Multiplied Their Haul
The initial theft was bad enough, but the hackers didn’t stop there. After converting the stolen assets into 21,957 Ethereum (ETH), valued at $53 million at the time, they played the long game. Instead of dumping the funds immediately, they held onto the ETH for nearly ten months. This patience paid off handsomely—by August 2025, the value of their holdings had skyrocketed to $94.63 million, thanks to savvy trading and market fluctuations.
Here’s where it gets wild. The hackers swapped 3,091 ETH for 13.26 million DAI, a stablecoin pegged to the U.S. dollar, to hedge against crypto’s volatility. They then funneled the DAI through multiple wallets before converting it back to ETH. This wasn’t just laundering—it was a masterclass in crypto arbitrage. By the time they were done, their portfolio was a mix of 14,436 ETH and 35.29 million DAI, nearly doubling their initial take.
- Converted stolen funds to 21,957 ETH ($53M).
- Held ETH for 10 months, capitalizing on market growth.
- Swapped 3,091 ETH for 13.26M DAI to stabilize value.
- Redistributed funds across multiple wallets for obfuscation.
Tornado Cash: The Hacker’s Getaway Car
Enter Tornado Cash, the crypto equivalent of a dark alley where funds vanish without a trace. In October 2025, the hackers deposited 2,834 ETH—worth $10.8 million—into this mixer protocol. For those unfamiliar, Tornado Cash breaks the link between sender and receiver by pooling and shuffling funds, making it nearly impossible to trace. It’s like tossing your cash into a blender and pulling out someone else’s bills.
The process was methodical. The hackers moved funds from their main wallet (starting with 0x4afb) through a series of intermediary addresses, including one tagged 0x3fe4, before funneling 2,834 ETH into Tornado Cash. Each transfer was a deliberate step to muddy the waters, leaving investigators grasping at shadows. Honestly, it’s both infuriating and impressive how these criminals exploit the very decentralization that makes crypto appealing.
Mixers like Tornado Cash are a double-edged sword—privacy for users, but a haven for bad actors.

Who’s Behind the Attack? A North Korean Connection
The plot thickens with suspicions pointing to the AppleJeus hacking group, allegedly tied to North Korea. A post-mortem report suggested these attackers are part of a broader network known for targeting crypto platforms to fund state-sponsored activities. North Korea’s involvement in crypto heists isn’t new—experts estimate the country has pocketed over $2.8 billion through similar schemes. That kind of money doesn’t just vanish; it fuels everything from military programs to cyberattacks.
What’s particularly unnerving is the precision of the attack. The use of INLETDRIFT malware suggests a level of sophistication that only well-funded groups can muster. It’s a stark reminder that the crypto space isn’t just a playground for tech enthusiasts—it’s a battleground where nation-states play dirty.
| Attack Element | Details |
| Target | Radiant Capital Lending Pool |
| Loss | $53M (initial), $94.63M (post-trading) |
| Method | Multi-signature wallet exploit via INLETDRIFT malware |
| Suspected Culprit | AppleJeus (North Korea-linked) |
| Laundering Tool | Tornado Cash (2,834 ETH, $10.8M) |
Radiant Capital’s Fight for Recovery
Radiant Capital didn’t sit idly by after the hack. They partnered with the FBI, blockchain analytics firms, and web3 security teams to track the stolen funds. But let’s be real—once funds hit a mixer like Tornado Cash, recovery chances drop to near zero. The platform’s been working tirelessly for a year, yet the hackers’ latest move shows just how slippery these criminals are.
This wasn’t Radiant’s first brush with disaster, either. Earlier in 2024, they lost $4.5 million to a flash loan exploit. Two hacks in one year? That’s enough to make anyone question the safety of DeFi lending. It’s a tough pill to swallow, but these incidents highlight the growing pains of a still-maturing industry.
Why This Matters for Crypto Investors
So, why should you care about a hack that happened to a DeFi platform? For one, it exposes the risks of decentralized systems. The same features that make crypto appealing—autonomy, privacy, no middleman—can be weaponized by bad actors. As an investor, I’ve always believed that understanding these risks is half the battle. You can’t just throw money into a protocol and hope for the best.
The Radiant Capital hack also raises questions about the future of crypto mixers. Tornado Cash has long been a lightning rod for controversy, with regulators arguing it enables money laundering. Yet, for many in the crypto community, it’s a vital tool for privacy. Where do we draw the line between freedom and accountability? It’s a debate that’s only going to get louder.

The Bigger Picture: Crypto’s Security Challenge
The Radiant Capital hack isn’t an isolated incident—it’s part of a broader wave of crypto exploits. In 2024 alone, hackers stole billions across various platforms, with DeFi protocols being prime targets. The decentralized nature of these systems, while revolutionary, creates unique vulnerabilities. Smart contracts, multi-signature wallets, and cross-chain bridges are all potential weak points.
Perhaps the most frustrating part is how preventable some of these attacks could be. Stronger audits, better key management, and user education could go a long way. But as long as there’s money to be made, hackers will keep probing for weaknesses. It’s like a digital arms race, and right now, the bad guys are holding their own.
The crypto industry needs to grow up fast if it wants to earn mainstream trust.

What’s Next for Radiant Capital and DeFi?
Radiant Capital is now at a crossroads. Rebuilding trust after two hacks in a year is no small feat. They’ll need to overhaul their security protocols, possibly adopting more robust multi-sig systems or third-party audits. For the broader DeFi space, this incident underscores the need for industry-wide standards. Without them, we’re just rolling the dice every time we interact with a protocol.
As for the hackers, they’re likely laughing all the way to the bank—or rather, the mixer. With $10.8 million already laundered and more potentially on the way, the odds of recovering the funds are slim. But if there’s one silver lining, it’s that incidents like this push the industry to innovate. Maybe, just maybe, the next generation of DeFi platforms will be built with these lessons in mind.
The Radiant Capital hack is a stark reminder that the crypto world is still the Wild West. It’s thrilling, it’s risky, and it’s full of surprises—some good, some downright disastrous. As investors and enthusiasts, we have to stay sharp, question everything, and never assume our funds are untouchable. Because in this game, the only thing certain is that hackers are always watching.
