Bybit Exchange Hack: The Biggest Crypto Hack in History

Crypto is everywhere these days. It has become a part of everyday life for many tech-savvy professionals and investors. Whether you’re a trader, a gamer who plays games on platforms like 777bet fun, or simply sending crypto to your friends you must have heard about the recent major cybersecurity breach with Bybit. The recent Bybit exchange hack that led to stealing millions of dollars worth of crypto, is still sending shock waves throughout the industry.

Let’s try to understand exactly what happened during the Bybit hack, the reasons and how you can protect your assets from such situations.

What happened during the Bybit exchange hack?

In February 2025, Bybit made global headlines for all the wrong reasons that it had suffered a huge security breach. Hackers broke into Bybit inner systems and stole over $600 million worth of crypto, making it the largest crypto hack ever.

The hack started quietly. At first, Bybit noticed weird activity with users’ accounts. Some customers couldn’t log in, others found that their account balances were mysteriously emptied. Within hours, Bybit confirmed the worst-case scenario: hackers had compromised their security and drained millions from user wallets.

For teens and younger users especially, seeing such a major hack unfold in real-time was shocking. Many had trusted Bybit with their crypto, only to see their savings vanish overnight. Social media exploded with reactions, questions, anger, and fear, all demanding answers from Bybit.

How did the hackers pull off the biggest crypto hack?

Everyone’s big question was, “How did hackers manage such a huge attack?”. The hackers discovered and exploited vulnerabilities in Bybit’s security protocols. Bybit reportedly had some weaknesses in its security systems, which led to this incident. Another important factor was social engineering: hackers pretended to be trusted insiders or staff, tricking employees into giving them access to critical internal systems related to approving blockchain transactions.

Crypto exchanges usually keep some crypto in “hot wallets” so was Bybit. They stored large amounts of crypto in these online wallets and once hackers gained access, transferring all the coins was a relatively easy task.

The immediate impact of the Bybit hack

The Bybit hack didn’t just affect the exchange itself — it had ripple effects across the whole crypto market:

Panic selling and market crash

As soon as news of the hack spread, investors panicked. Many of those who might have invested their allowance or small savings, rushed to sell their crypto. Bitcoin, Ethereum, and other popular coins prices dropped immediately.

Loss of trust in exchanges

Bybit was considered safe and reliable before the hack. But after such a huge breach, many users felt betrayed. They started to doubt not just Bybit, but in Binance, OKX and crypto exchanges in general, wondering if their crypto was truly secure anywhere online.

Calls for tougher regulations

The massive hack prompted governments worldwide to demand stricter rules for crypto exchanges. Regulators tried to implement measures to further protect investors’ assets claiming that the security measures taken by Bybit were not enough.

What happened next

After the massive breach Bybit had to quickly take action.

Bybit detected unauthorized activity involving one of our ETH cold wallets. The incident occurred when our ETH multisig cold wallet executed a transfer to our warm wallet. Unfortunately, this transaction was manipulated through a sophisticated attack that masked the signing…

Compensations

Understanding that young customers were deeply affected, Bybit announced plans to reimburse users who lost their crypto. While this helped ease some anxiety, many young users remained worried about trusting the exchange again.

Legal and regulatory challenges

Due to the massive size of the hack, Bybit faced investigations and possible legal consequences. Regulators began closely watching Bybit and similar exchanges, signaling tighter rules in the future. Young crypto users watched closely to see if stricter rules would ultimately make crypto safer or less fun.

How to keep your crypto safe: Post-Bybit hack lessons

Use hardware wallets because they are the safest way to protect your crypto. Even if an exchange is hacked, your crypto stays safe because it’s stored offline. Be careful with hot wallets and only keep small amounts in hot wallets for daily spending or gaming. Store the majority of your crypto safely offline. Always enable 2FA on every crypto account. It adds a second layer of protection, making it harder for hackers to access your account. Don’t reuse passwords. Use a strong, unique password for each crypto account. Use password managers to help you securely store these complicated passwords.

Can trust be restored in crypto exchanges after Bybit?

The big question after a massive hack like Bybit’s is: Can exchanges ever fully regain trust? For young investors, trust matters — a lot. Crypto is exciting, fun, and filled with opportunities, but trust is key for continued participation.

After Bybit’s quick response, promises of reimbursement, and improved security measures, some trust began returning. However, rebuilding trust fully takes time. Young investors need reassurance that exchanges genuinely care about security and customer safety.
