Biggest Crypto Exchange Hacks & Incidents
1. Bybit Mega Hack (2025)
One of the largest crypto heists in history saw hackers steal approximately $1.5 billion from a crypto exchange wallet. This attack highlighted vulnerabilities during wallet transfers and operational processes. The Bybit Mega Hack of 2025 stands as the largest crypto exchange breach in history, sending shockwaves across the entire cryptocurrency industry. On February 21, 2025, hackers successfully stole approximately $1.4–$1.5 billion worth of Ethereum, making it one of the biggest financial thefts ever recorded—not just in crypto, but globally.
The attack occurred during what appeared to be a routine transfer of funds from a cold wallet (offline storage) to a warm wallet. However, this process was secretly manipulated by attackers who altered the transaction interface, tricking authorized signers into approving a malicious transaction. As a result, the hackers gained control of the wallet and transferred over 400,000 ETH to unknown addresses. What made this hack particularly alarming was the method used. Instead of directly breaking into the blockchain, the attackers exploited a third-party wallet system and human trust through a sophisticated social engineering and supply chain attack. Investigations later linked the breach to the infamous Lazarus Group, a state-sponsored cybercrime organization known for targeting financial systems.
This incident highlighted a crucial lesson for the crypto industry: even highly secure systems like cold wallets can be compromised if the transaction approval process is manipulated. The Bybit hack exposed weaknesses not just in technology, but in operational security and third-party dependencies. It ultimately pushed exchanges worldwide to rethink their security frameworks, emphasizing stricter verification processes, improved wallet infrastructure, and stronger protection against social engineering attacks.
2. Step Finance Breach (2026)
Hackers compromised executive devices and gained unauthorized access, stealing around $40 million. This incident proved that human-level vulnerabilities can be just as dangerous as technical flaws.The Step Finance Breach of 2026 is one of the most important examples of how modern crypto attacks are shifting from technical vulnerabilities to human and operational weaknesses. In late January 2026, the Solana-based DeFi platform Step Finance suffered a major security incident in which attackers drained between $30 million and $40 million worth of digital assets from its treasury wallets.
Unlike traditional crypto exchange hacks that exploit smart contract bugs, this breach was caused by compromised devices belonging to the platform’s executive team. Hackers gained access to these devices and were able to extract sensitive credentials, including private keys and transaction signing access. This allowed them to bypass internal security controls and initiate unauthorized transactions without directly attacking the blockchain infrastructure. Once inside the system, the attackers unstaked approximately 261,000+ SOL tokens and transferred them out of treasury wallets within a short time frame. The speed and coordination of the attack demonstrated a high level of planning and execution. The breach also caused a sharp collapse in the platform’s token value and severely impacted user confidence.
3. Insider & Data Breaches
Cases like exchange support staff being bribed to leak user data show how insider threats are increasing. Poor access control contributed to around 11% of exchange hacks.
Insider and data breaches have become a growing threat in 2026, contributing significantly to both crypto exchange hacks and crypto trading hacks. In many cases, employees or support staff with access to sensitive systems are either manipulated through social engineering or intentionally leak data for financial gain. These breaches often expose critical user information such as login credentials, KYC data, and API keys, which attackers later use to access accounts and execute unauthorized trades or withdrawals.
Such incidents highlight that internal security is just as important as external defenses. Without strict access controls, monitoring, and employee verification systems, even trusted insiders can become a major vulnerability for crypto platforms.
4. Phishing & Social Engineering Attacks
Phishing remains the most common attack vector, responsible for nearly 48% of breaches. Hackers increasingly target users rather than systems. Phishing and social engineering attacks remain the most common drivers behind crypto exchange hacks and crypto trading hacks in 2026. Instead of directly attacking secure systems, hackers trick users and employees into revealing sensitive information such as login credentials, private keys, or one-time passwords. This is often done through fake websites, emails, or messages that closely mimic legitimate crypto platforms.
These attacks are highly effective because they exploit human psychology rather than technical weaknesses. Once attackers gain access, they can quickly take control of accounts and transfer funds without triggering immediate suspicion. The rise of such tactics highlights the urgent need for user awareness, strong authentication methods, and continuous monitoring to prevent unauthorized access.
Key Trends in Crypto Exchange Hacks (2026)
Phishing and social engineering attacks continue to be the leading causes of crypto exchange hacks and crypto trading hacks in 2026, creating major challenges for every Crypto Exchange Development Company. Instead of breaking into secure systems directly, attackers focus on manipulating users and employees into sharing sensitive information such as login credentials, private keys, and one-time passwords. These attacks are typically carried out through fake websites, emails, or messages that closely imitate trusted crypto platforms, making them difficult to detect.
What makes these tactics so dangerous is their ability to exploit human psychology rather than technical vulnerabilities. Once access is gained, hackers can quickly take control of accounts and transfer funds without raising immediate suspicion. This growing trend highlights the importance for any Crypto Exchange Development Company to implement strong authentication systems, continuous monitoring, and user education to effectively reduce the risk of unauthorized access.
Shift from Code Exploits to Human Exploitation
Hackers now focus more on manipulating users and employees than breaking code systems.
Private Key Compromise Dominance
Nearly 88% of stolen crypto is linked to private key exposure.
Rise of Social Engineering Attacks
In 2026, social engineering caused more damage than smart contract vulnerabilities.
Targeting Hot Wallets
Over 80% of attacks focus on hot wallets due to weak key management.

How Hackers Execute Crypto Exchange Attacks
In 2026, hackers execute crypto exchange hacks and crypto trading hacks using a combination of technical exploits and psychological manipulation. These attacks are no longer simple or one-dimensional; instead, they involve carefully planned steps designed to bypass security layers and exploit both systems and human behavior. Most attacks begin with reconnaissance, where hackers gather information about the exchange, its employees, or its users. This can include analyzing public data, scanning for vulnerabilities, or identifying weak entry points such as poorly secured APIs or exposed credentials. Once a target is identified, attackers often use phishing or social engineering techniques to gain initial access by tricking users or staff into revealing sensitive information.
After gaining entry, hackers typically escalate their privileges within the system. This may involve accessing admin panels, exploiting backend vulnerabilities, or compromising internal tools. In many crypto trading hacks, attackers target API keys or trading bots, allowing them to manipulate trades or withdraw funds without directly logging into user accounts.
Another common method involves private key theft, where attackers gain control over wallet access. This can happen through malware-infected devices, insecure storage, or compromised systems. Once private keys are obtained, hackers can instantly transfer assets, making recovery extremely difficult.
Finally, attackers execute the fund transfer phase, where stolen assets are quickly moved across multiple wallets and often converted or laundered through mixers or decentralized platforms. This step is designed to erase traces and make tracking nearly impossible. Modern crypto exchange attacks are a blend of strategy, technology, and deception, showing that securing a platform requires not only strong systems but also awareness and vigilance at every level.
Phishing & Fake Platforms
Users are tricked into revealing login credentials or private keys through fake websites or emails.
Private Key Theft
Attackers exploit poor storage practices or compromised devices to access wallets.
Insider Attacks
Employees with privileged access are manipulated or bribed to leak sensitive data.
Smart Contract Exploits
Vulnerabilities in DeFi protocols are exploited to drain funds.
Infrastructure Attacks
Hackers target APIs, servers, or admin panels to gain system-level access.
Lessons Learned from Crypto Hacks
The rise of crypto exchange hacks and crypto trading hacks in recent years has provided critical lessons for the entire crypto industry. One of the most important realizations is that human error remains the weakest link in security. Even highly advanced systems can be compromised if users or employees fall victim to phishing or social engineering attacks. This highlights the need for continuous training and awareness alongside technical protections.
Another key lesson is that security must be multi-layered. Relying on a single line of defense is no longer effective, as attackers use multiple methods to breach systems. From private key management to API security and access controls, every layer must be strengthened to reduce the risk of exploitation. Crypto hacks have also shown the importance of real-time monitoring and rapid response. In many cases, delays of just a few minutes have led to massive financial losses. Exchanges must be able to detect suspicious activity instantly and take immediate action to prevent further damage.
Additionally, the industry has learned that securing infrastructure alone is not enough. Operational processes, third-party integrations, and internal access systems must also be carefully managed. Weaknesses in any of these areas can open the door to attackers.
