Episode: The Global Story: How North Korean Hackers Launched History's Biggest Heist
Release Date: March 9, 2025
Host: Valerie Sanderson
Guest: Joe Tidy, BBC Cyber Correspondent
1. Introduction to the Bybit Heist
Valerie Sanderson opens the episode by detailing a monumental cybersecurity breach that has stunned the cryptocurrency world. Last month, the cryptocurrency trading platform Bybit fell victim to what is potentially the largest heist in history. In a mere two minutes, hackers siphoned off approximately $1.46 billion worth of Ethereum from Bybit's secure cold wallets (00:34).
Notable Quote:
"It is likely the biggest heist in history. When the cryptocurrency trading platform Bybit was targeted last month, hackers managed to steal almost $1.5 billion in just two minutes." – Joe Tidy (00:34)
2. Understanding Bybit and the Nature of the Attack
Bybit, a prominent cryptocurrency exchange with around 60 million customers, facilitates the exchange of various currencies for cryptocurrencies like Bitcoin and Ethereum. The platform operates with a "hot wallet" for daily transactions and a "cold wallet" akin to a bank’s safe, storing bulk cryptocurrency offline to protect against hacks.
On the night of the attack, hackers exploited the transfer mechanism between Bybit's cold and hot wallets. By compromising an employee from SafeWallet, a company responsible for facilitating these transfers, the hackers redirected $1.46 billion worth of Ethereum to their own cryptocurrency exchange instead of Bybit's hot wallet (01:35).
Notable Quote:
"When Bybit pressed send on their computers, everything looked normal. So they pressed send on $1.46 billion worth of Ethereum. And it didn't go to the Bybit hot wallet. It went to the hackers cryptocurrency exchange." – Valerie Sanderson (01:35)
3. The Unprecedented Scale of the Heist
Joe Tidy emphasizes the unparalleled scale of this heist, surpassing previous significant cryptocurrency thefts. The most notable prior incident was the Ronin Network breach in 2022, where over $600 million were stolen, marking it one of the largest in decentralized finance (03:23). The Bybit heist dwarfs even this, establishing itself as potentially the most extensive financial theft in history.
Notable Quote:
"This is absolutely the biggest crypto theft in history... we think this is the biggest ever theft in history, full stop." – Valerie Sanderson (03:27)
4. Immediate Aftermath and Bybit’s Response
Bybit’s CEO, Ben Zhao, quickly realized the severity of the breach when notified by the security team. Initially believing it to be 30,000 Bitcoin, they were shocked to discover the total loss of 401,000 Ethereum coins. Demonstrating transparency, Zhao held a live stream to inform and reassure customers, addressing their concerns and outlining steps to recover the lost funds. Bybit successfully secured backup loans from investors and began efforts to reclaim the stolen cryptocurrency.
Notable Quote:
"I'm intending to make this live stream go a bit longer so I can answer all of our community's questions, concerns and any issues we can address." – Ben Zhao, Bybit CEO (04:20)
5. Attribution to the Lazarus Group and North Korea
Investigators swiftly identified the Lazarus Group, an elite hacking team linked to the North Korean regime, as the primary suspects behind the heist. This group has a notorious history of state-sponsored cyberattacks aimed at bolstering North Korea's economy amidst international sanctions. Their previous operations include the 2014 Sony Pictures attack, 2021 Kucoin hack, and the 2022 Ronin Network breach.
Notable Quote:
"They didn't just go after one victim; the whole cold wallet drained 401,000 Ethereum coins, $1.46 billion." – Valerie Sanderson (03:27)
Additional Quote:
"They are a very active pipeline of taking talented children who are good at maths and turning them into, you know, superb hackers." – Valerie Sanderson (19:56)
6. Methods of the Heist and Laundering Stolen Funds
The Lazarus Group employed sophisticated techniques to execute and obscure the heist. Utilizing the transparency of blockchain, they meticulously tracked and redirected funds across numerous wallets to complicate tracing efforts. The ultimate goal was to cash out the stolen cryptocurrency, converting it into fiat money. Forensic investigators like Tom Robinson of Elliptic are tirelessly monitoring these transactions to freeze assets before they vanish into less transparent avenues.
Notable Quote:
"The North Koreans are particularly good at this now. They have developed really sophisticated systems, techniques, patterns and behaviors to try and obscure the origin of that money." – Valerie Sanderson (12:29)
7. Bybit’s Innovative Recovery Efforts
In response to the breach, Bybit launched the Lazarus Bounty, an initiative encouraging global volunteers to monitor blockchain transactions and assist in freezing the stolen funds. This collaborative effort has already retrieved approximately $40 million, rewarding participants with substantial incentives. Despite recovering only a fraction of the total stolen amount, this initiative marks a significant step in combating such large-scale cyber thefts.
Notable Quote:
"They are being given money. And so far, I think the last time we looked, about 17 people had been helping. They have recovered, I think, about $40 million." – Valerie Sanderson (15:58)
8. Industry Vulnerabilities and Security Failings
The episode underscores systemic vulnerabilities within the cryptocurrency industry. Lazarus Group’s repeated breaches highlight the sector's dispersed security measures and the "move fast, break things" ethos that often compromises robust defenses. Bybit's incident, along with others like Kucoin and the Ronin Network, illustrate persistent security shortcomings that make major platforms attractive targets for sophisticated hacking groups.
Notable Quote:
"They have pivoted quite heavily from Traditional finance banks, ATMs, the Swift network, very, very heavily into cryptocurrency for a reason... showing that there are major problems in the crypto world." – Valerie Sanderson (21:04)
9. Government and International Response
Governments worldwide face significant challenges in responding to such cybercrimes. Despite clear attribution to North Korean entities like the Lazarus Group, actionable responses remain limited due to geopolitical complexities. The FBI has placed members of Lazarus Group on its Cyber Most Wanted list, but pursuing extradition or legal action against North Korean hackers is fraught with difficulties.
Notable Quote:
"Even if you manage to find out who the hackers are and you have names, addresses, photographs, how can you arrest them? Because, of course, the North Koreans don't cooperate with international requests for extraditions." – Valerie Sanderson (18:25)
10. Future Implications and Confidence in Cryptocurrency
The Bybit heist has broader implications for the cryptocurrency market. Episodes like these undermine public confidence, causing fluctuations in cryptocurrency valuations. While some argue that crypto’s decentralization is its strength, high-profile hacks expose the fragility of security within the ecosystem. Additionally, governmental proposals, such as President Trump’s suggestion of a crypto strategic reserve, indicate increasing institutional interest, albeit with heightened risks of large-scale cyber threats.
Notable Quote:
"But anytime you stockpile anything, the bigger the stockpile, the more likely you are to be at risk of hacking." – Valerie Sanderson (22:27)
Additional Quote:
"Every single time this happens, it does completely understandably knock the confidence in what is a very complicated and fast moving industry." – Valerie Sanderson (23:15)
Conclusion
The Global Story episode meticulously unpacks the audacious $1.46 billion Bybit hack, attributing it to North Korea's Lazarus Group. It highlights the evolving tactics of state-sponsored cybercriminals, the cryptocurrency industry's security inadequacies, and the complex interplay between technological innovation and vulnerability. As the crypto landscape continues to grow, the episode underscores the critical need for enhanced security measures and international cooperation to safeguard digital assets.
