Security concerns are a major issue in the web3 realm. To address this, constant updates and advanced solutions are crucial. Shockingly, there have been approximately 1,435 hacking incidents in the crypto space, resulting in staggering losses of over $31.6 billion.

Now, let’s delve into some of the significant hacking events that transpired in the past year.

Major Crypto Hacks in the Last Year

In 2023, despite a decrease in overall hack volumes by over 50%, hackers still managed to steal around $1.7 billion worth of cryptocurrency. Several high-profile hacking incidents occurred throughout the year, impacting projects like Mixin Network, Multichain, Euler Finance, etc.

Mixin Network

Mixin Network, a crypto project based in Hong Kong, experienced a significant setback when it fell victim to the largest crypto exploit of the year. On September 23, the company abruptly ceased operations after hackers siphoned off a staggering $200 million from users’ hot wallets. Mixin reported that hackers attacked the database of its cloud service provider, potentially compromising the private keys of users’ accounts.

Euler Finance

In March 2023, the DeFi lending protocol Euler fell victim to an exploit resulting in the disappearance of $197 million worth of crypto. The attacker manipulated the exchange rates between Euler-issued stablecoins, triggering liquidations of borrower positions and siphoning funds from the protocol. However, in a surprising turn of events, the attacker later returned most of the stolen funds, providing relief for the victims.

Multichain

Cross-chain bridge Multichain suffered an exploit in July, resulting in the loss of $126 million in cryptocurrencies across different supported blockchains. The hack occurred shortly after the bridge was halted due to unforeseeable circumstances. The exact cause remains unclear, with speculation suggesting compromised smart contract private keys and concerns about the involvement of the Multichain team.

Poloniex

In November 2023, suspected North Korean Lazarus Group hackers stole $120 million from Poloniex’s hot wallets, likely by gaining access to private keys. Trading and withdrawals were halted, with the exchange promising reimbursement to affected users. Poloniex, acquired by Tron founder Justin Sun in 2019, has operated as a centralized exchange since 2014.

BonqDAO

On February 2nd, 2023, the Polygon DeFi protocol BonqDAO suffered a $120 million loss in the largest oracle exploit of the year. Exploiting a vulnerability in BonqDAO’s price feed smart contract, the attackers manipulated the price of the ALBT token, enabling them to borrow 100 million BEUR stablecoins and swap them for other tokens on Uniswap.

Frequently, the root cause of these incidents lies in the exploitation of private keys, providing unauthorized access to users’ funds. This vulnerability, often exploited by attackers, poses a significant threat to the security of cryptocurrency platforms. Moreover, many of these security breaches occur due to the insufficient protection of project security systems. When these systems are compromised, attackers can infiltrate the platform’s user database, gaining access to sensitive information and hot wallets holding users’ assets.

Given the severity of these security challenges, it becomes imperative for security professionals to devise robust strategies to address similar cases effectively. By understanding the vulnerabilities exploited by attackers and implementing comprehensive security measures, platforms can mitigate the risks associated with unauthorized access and protect users’ funds from malicious actors.

Therefore, let’s delve deeper into the strategies employed by security professionals to safeguard cryptocurrency platforms and enhance user security in the face of such threats.
