On February 21, 2025, the crypto world was rocked by news of a staggering $1.4 billion hack targeting Bybit, one of the largest cryptocurrency exchanges. Blockchain investigators, including Arkham Intelligence and pseudonymous sleuth ZachXBT, quickly pointed the finger at North Korea’s infamous Lazarus Group—a state-sponsored hacking collective notorious for its sophisticated cybercrimes. This wasn’t a brute-force attack on Bybit’s code; it was a meticulously executed exploitation of human vulnerabilities, underscoring a harsh truth: in the Wild West of crypto, even the biggest players can fall. But could institutional custody with insurance have shielded users from this financial catastrophe? Let’s dive into what happened and explore how a more robust security framework might have made a difference.

For a limited time, Digital Wealth Partners (DWP) is lowering their minimum requirement for new clients. Instead of the usual $500,000 threshold, DWP is welcoming clients who hold at least 50,000 XRP. If you’ve been considering working with DWP for custody, this is a great opportunity to explore their services with a reduced minimum. This opportunity is available for the next 7 days.

The Heist: How Lazarus Pulled It Off

The Bybit hack wasn’t about cracking impenetrable blockchain encryption or exploiting a smart contract flaw. Instead, Lazarus relied on social engineering—manipulating people rather than systems. Reports suggest the group spent months laying the groundwork, likely using phishing schemes, fake job offers, or other tailored scenarios to trick Bybit employees or users into granting access to critical systems. Once inside, they siphoned off over $1.4 billion in Ethereum and related tokens, a haul so massive it could make North Korea one of the world’s largest Ether holders if confirmed.

This isn’t Lazarus’s first rodeo. The group has a rap sheet that includes the $600 million Ronin Network hack in 2022 and a $308 million heist from Japan’s DMM Bitcoin in 2024. Their playbook often involves patiently exploiting human error, then laundering the proceeds through mixers and unregulated exchanges. The Bybit attack, however, stands out for its scale and audacity, shaking confidence in centralized exchanges and reigniting debates about crypto security.

The Vulnerability of Centralized Exchanges

Bybit, like many exchanges, operates as a centralized platform, holding vast amounts of user funds in its own wallets. This centralization makes it a juicy target—hackers only need one point of entry to access billions. While Bybit likely employed advanced security measures (firewalls, multi-signature wallets, etc.), the human element proved its Achilles’ heel. No amount of code can stop an employee from clicking a malicious link or a user from handing over credentials under a convincing ruse.

This is where the story gets grim for Bybit’s users. Unlike traditional banks, crypto exchanges don’t come with government-backed deposit insurance like the FDIC. When hacks happen, users are often left holding the bag—or rather, an empty wallet. Bybit has not yet detailed its reimbursement plans as of February 22, 2025, but history suggests that full recovery is rare. The question looms: could a different approach have prevented this disaster?

Institutional Custody: A Safer Haven?

Enter institutional custody—a service where a trusted third party, often a regulated financial institution, securely holds crypto assets on behalf of users or exchanges. Companies like Digital Wealth Partners offer such solutions, using offline “cold” storage, multi-signature protocols, and rigorous access controls to protect funds. Unlike Bybit’s centralized hot wallets, which are online and thus more exposed, institutional custodians prioritize isolation from the internet, making them harder to breach.

Had Bybit users partnered with an institutional custodian, the $1.4 billion might not have been sitting in a single, hackable pot. Custodians distribute assets across multiple secure locations, often requiring physical and multi-party approval for withdrawals. Even if Lazarus tricked an employee, they’d face additional layers of defense—think bank vault-level security rather than a digital piggy bank. This分散 (decentralized, in a custody sense) approach could have limited the damage, if not prevented the theft entirely.

Insurance: The Safety Net Crypto Needs

But custody alone isn’t enough—insurance is the game-changer. Institutional custodians often back their services with insurance policies covering theft, hacks, or operational failures. For example, clients in institutional custody receive million in coverage per client, underwritten by reputable insurers like Lloyd’s of London.

Contrast this with the current reality. Most exchanges, including Bybit, maintain discretionary “insurance funds” fueled by trading fees, but these are rarely sufficient for mega-hacks. After the 2018 Youbit hack in South Korea (also linked to North Korea), the exchange’s insurer denied a $2.8 million claim, citing inadequate disclosure—a loophole that left users high and dry. Institutional-grade insurance, tied to custody, is more robust, with clear terms and audited reserves, offering real protection rather than hollow promises.
