Bybit’s $1.5 Billion Crypto Heist: What Happened, Who’s Behind It, and How to Protect Your Assets
- Sanjaykumar pawar
In a shocking turn of events, crypto exchange Bybit has suffered one of the biggest hacks in history, with attackers making off with a staggering $1.5 billion worth of Ethereum. This breach has sent ripples through the crypto community, reigniting fears about security vulnerabilities in even the most established platforms.
So, what exactly happened? Who’s behind it? And most importantly—how can you protect your own crypto assets? Let’s break it down.
The Hack: How Bybit Lost $1.5 Billion
On February 21, 2025, Bybit confirmed that one of its cold wallets—which are typically considered more secure than hot wallets—was compromised. The hack occurred during a routine transfer from a cold wallet to a warm wallet. Somehow, the attackers intercepted the transaction and redirected the funds to an unknown address.
What Bybit Says
Bybit CEO Ben Zhou quickly reassured users:
- No other wallets were affected—only this one Ethereum cold wallet was compromised.
- User funds are safe, and the exchange has enough reserves to cover the loss.
- Withdrawals and trading remain fully operational, though there might be minor delays.
Bybit also secured 80% of the lost funds through bridge loans and is actively working with law enforcement to track down the hackers.
Who’s Behind the Attack?
While no one has officially claimed responsibility, blockchain security experts suspect that North Korean hackers—possibly linked to the infamous Lazarus Group—are behind the breach.
Why North Korea?
- Experts from Arkham Intelligence and Elliptic found patterns similar to past North Korean-linked hacks.
- The stolen funds have already started moving across various wallets in an attempt to launder them.
- The Lazarus Group has been behind multiple high-profile crypto hacks in recent years, allegedly using stolen funds to fund the North Korean regime.
If these suspicions are correct, this would be one of the largest cyber heists ever, surpassing even the $611 million Poly Network hack in 2021.
What This Means for Crypto Security
The Bybit hack is yet another reminder that even top exchanges aren’t immune to cyber threats. In the past few years, hackers have stolen billions from crypto platforms, often exploiting weaknesses in wallet security and internal processes.
Some of the biggest crypto hacks in history include:

- Coincheck (2018): $534 million stolen
- Poly Network (2021): $600 million stolen (but most of it was later returned)
- Ronin Network (2022): $600 million stolen
With hackers getting more sophisticated, exchanges and users alike must step up their security game.
How to Protect Your Crypto Assets
If a massive exchange like Bybit can get hacked, it’s a wake-up call for all of us. Here’s how you can keep your crypto safer:
1️⃣ Use Hardware Wallets
- Unlike exchange wallets, hardware wallets store your crypto offline, making them immune to online hacks.
- Popular options: Ledger, Trezor
2️⃣ Enable Two-Factor Authentication (2FA)
- ALWAYS enable 2FA for your exchange accounts.
- Use an authenticator app (Google Authenticator, Authy) instead of SMS for better security.
3️⃣ Spread Out Your Holdings
- Don’t keep all your assets in one place.
- Consider diversifying between exchanges, cold wallets, and decentralized storage solutions.
4️⃣ Watch for Phishing Scams
- Hackers often impersonate exchanges and trick users into revealing their login credentials.
- Double-check email addresses and never click on suspicious links.
5️⃣ Stay Updated on Security Best Practices
- Crypto security is always evolving. Follow reputable security blogs, exchanges, and analysts for updates.
Final Thoughts: Is Your Crypto Really Safe?
The Bybit hack is a harsh reminder that crypto security is a constant battle. While exchanges do their best to strengthen defenses, hackers are always looking for new vulnerabilities.
So, what can we learn from this?
✅ If you’re serious about crypto, take security into your own hands.
✅ Don’t rely solely on exchanges to protect your funds.
✅ Adopt best practices like using hardware wallets and enabling 2FA.
