How the Bybit Hack Revolutionized Crypto Custody and Compliance

Introduction: The Bybit Hack’s Impact

In February 2025, the cryptocurrency exchange Bybit faced a staggering $1.4 billion hack, unveiling critical weaknesses in what were previously deemed secure custody systems like cold storage and multisignature wallets. This incident not only marked a significant moment in crypto history but also shifted the space of security protocols and regulatory measures across the industry.

The Scale of the Hack

At the time, the Bybit hack was considered the largest theft in cryptocurrency history, although it was later overshadowed by the revelation of a $3.5 billion loss from the Chinese mining pool LuBian in 2020. Ishai Shoham, head of product at Utila, pointed out that the breach highlighted the fragility of cold storage and multisig systems, stating, “These systems can be compromised if the approval flow, transaction visibility, or signer environment is manipulated.”

Regulatory Response to the Incident

This incident prompted the Financial Action Task Force (FATF) to call for urgent action from global regulators to tackle the risks of illicit finance associated with cryptocurrencies. Exchanges began reinforcing their transaction approval processes and raised the bar for detecting and managing security breaches. The hack served as a wakeup call, stressing the need for improved standards.

Understanding the FATF’s Role

The FATF is an intergovernmental organization that sets guidelines on combating money laundering and terrorist financing. While their recommendations aren’t legally binding, member countries are expected to adhere to them. Non-member states that fail to comply risk being placed on the FATF gray list, affecting their access to financial aid and international banking relationships. In a June 2025 report, FATF categorized the Bybit hack as the largest crypto theft to date, citing the growing complexity of cross-chain activities and stablecoins as factors that raise risks faster than current controls can contain.

Gaps in the Current System

Joshua Chu, an asset recovery lawyer and co-chair of the Hong Kong Web3 Association, addressed the persistent flaws in the Travel Rule and enforcement measures. He emphasized how, once funds enter decentralized finance (DeFi), preventing money laundering becomes increasingly challenging, especially with automation tools speeding up these processes.

The Link to North Korean Hackers

Numerous security experts, including the FBI, have alleged connections between the Bybit hack and North Korean hackers, particularly the Lazarus Group. Blockchain investigator ZachXBT was among the first to officially tie the hackers to this incident, further amplifying concerns over the geopolitical implications of cryptocurrency security.

Kim Jong Un: A Surprising Influence

Interestingly, the fallout from the Bybit hack led some to label Kim Jong Un as the most influential figure in the crypto world in 2025. Despite the political discussions surrounding cryptocurrency regulations, the significance of the Bybit incident dominated industry dialogue, shaping future security standards.

Regulatory Moves in the Asia-Pacific Region

In response to the hack, Singapore tightened its licensing regulations, requiring unlicensed crypto firms to either secure permits or exit the market. Other countries in the region, like Thailand and the Philippines, initiated similar enforcement campaigns, signaling a broad shift towards stricter oversight of the cryptocurrency industry.

Shifts in Industry Perspective

The Bybit hack fundamentally altered the industry’s understanding of custody security and illicit fund movements. Shoham highlighted that the weaknesses were no longer just about cryptographic vulnerabilities. He explained, “Once funds leave a compromised wallet, attackers can rapidly disperse and reassemble value across chains, outpacing human response time.”

Decentralized Protocols: A Double-Edged Sword

The incident reignited debates regarding decentralized infrastructure and the responsibilities tied to it. As stolen funds were moved across chains, attention turned back to routing networks such as THORChain and eXch, which had been exploited by attackers to swap assets without needing centralized intermediaries. Supporters of these decentralized models argue that these platforms are merely neutral infrastructures, while critics contend that their frameworks facilitate large-scale laundering of stolen funds.

New Standards for Crisis Management

In the aftermath of the breach, Bybit’s approach to crisis management set a new benchmark in the industry. Instead of halting withdrawals—a common reaction during such events—Bybit continued to allow users to withdraw their funds while sourcing Ether from partner exchanges to meet immediate demands. CEO Ben Zhou actively communicated with users through live streams, providing updates on recovery efforts, which helped restore trust.

The Future of Crisis Response

This proactive approach has influenced how other exchanges prepare for and manage major breaches, with real-time communication now considered important. As a result of the hack, Bybit has maintained its position as one of the largest cryptocurrency exchanges in the world, frequently ranking as the second-largest by daily trading volume.

The Bybit hack wasn’t just another security breach; it was a important moment that reshaped the entire cryptocurrency space. It underscored the urgency for more solid regulatory frameworks and security measures. As the industry continues to evolve, the lessons learned from this incident will undoubtedly play a major role in determining the future of cryptocurrency security and compliance.
