Bybit Faces Historic $1.5B Hack: Largest Crypto Theft Ever?

The crypto industry is reeling from what could be the biggest exchange hack in history. On February 21, 2025, Bybit—one of the world’s leading crypto exchanges—suffered a massive security breach, with hackers stealing between $1.4 billion and $1.5 billion in Ethereum from the platform’s cold wallets.

This attack has shaken confidence in Bybit, sparking fears of deeper security vulnerabilities in centralized exchanges.

Key Questions:

Who was behind the hack?
How will this impact Bybit and the wider crypto market?
Will users be reimbursed, and can Bybit recover?

Let’s break down what we know so far.

How the Bybit Hack Unfolded

Timeline of the Attack (February 21, 2025)

Early Hours (UTC): On-chain data shows large, unauthorized ETH withdrawals from Bybit’s cold wallets.
Midday: Blockchain security firms PeckShield and CertiK detect abnormal activity, flagging Bybit.
Afternoon: Bybit acknowledges the breach, with CEO Ben Zhou confirming a major security incident.
Evening: Ether prices jump 5%, partially driven by Bybit’s $300M OTC purchases to stabilize its reserves.

How Much Was Stolen?

Estimated Losses:
$1.4B – $1.5B stolen, making it potentially the largest crypto hack ever.
Primarily Ethereum: Attackers drained cold storage ETH, bypassing Bybit’s security.

For comparison, here’s how this hack stacks up against past crypto thefts:

If confirmed, this would surpass Coincheck as the biggest exchange hack in history.

Who’s Behind the Attack? Is North Korea Involved?

Early Signs Point to the Lazarus Group

Security analysts suspect North Korea’s Lazarus Group, known for its sophisticated state-backed cyber warfare, may be involved.

Similar attack patterns: Lazarus has previously hacked Axie Infinity ($625M) and Harmony ($100M).
Targeting ETH: North Korean hackers often favor Ethereum theft, using mixers like Tornado Cash to launder funds.
Geopolitical Timing: Sanctions are tightening on North Korea, increasing its reliance on stolen crypto for funding.

“Bybit hack has Lazarus fingerprints all over it. Expect more centralized exchanges to be targeted next.”

If North Korea is confirmed, this would signal a new wave of crypto exchange vulnerabilities.

Market Impact: ETH Price Rises Despite the Hack

Surprisingly, Ether prices jumped 5% after the attack. Why?

Key Reasons for ETH’s Price Spike:

• Bybit’s $300M OTC buyback to maintain liquidity.
• Traders speculating on Ethereum’s resilience despite security risks.
• Institutional demand keeping ETH strong as Bitcoin nears $100K.

Current Market Reaction (Feb 22, 2025):

• ETH Price: Up 5.1% since the hack.
• Bybit’s token (BIT): Down 22%, reflecting confidence loss.
• Altcoins: Mixed, with some panic-driven selling.

Could this hack push investors toward decentralized exchanges (DEXs)?

Can Bybit Recover? What’s Next for the Exchange?

Bybit’s response in the coming days will determine its future.

✅ Steps Bybit Must Take to Restore Trust:

1️⃣ Full transparency on the attack – Investors need details on how security failed.
2️⃣ Reimbursement plan for affected users – Will Bybit cover losses or rely on insurance?
3️⃣ Security overhaul & external audits – Hiring top firms to prevent future breaches.
4️⃣ Better cold storage protections – If cold wallets can be hacked, no exchange is safe.

Ben Zhou (Bybit CEO) on X: “We are working with top security firms and industry peers to recover funds and strengthen our defenses.”

If Bybit fails to handle this crisis, users may withdraw funds en masse—jeopardizing the exchange’s future.

Final Thoughts: The Fallout from Bybit’s $1.5B Hack

This could be the largest crypto exchange hack ever.
North Korea’s Lazarus Group is a prime suspect.
Bybit must act fast to rebuild trust—or risk losing users forever.
