Crypto exchanges tighten security after record $6.3 billion Binance hack

Major cryptocurrency exchanges are reviewing their security arrangements and sharing information to prevent similar attacks. The incident has exposed weaknesses in the industry as digital currencies become increasingly connected to the global financial system.

Coinbase said it had made changes to systems used to store cryptocurrency keys offline. The company said the changes were made “solely out of an abundance of caution”, while Kraken said it was studying security incidents across the industry to improve its own protection.

Record Binance hack raises industry concerns

Security experts and industry executives say cryptocurrency companies must act quickly to protect their systems. The need for stronger security has become more urgent as US regulators under President Donald Trump support greater use of digital assets in the financial system.

This growing connection with mainstream finance could increase the impact of future cyberattacks. Companies may face greater financial and public pressure if hackers gain access to customer funds.

“For crypto to reach its full potential, the security situation must be addressed immediately,” said Chris Perkins, Franklin Templeton’s head of crypto.

Binance, the world's largest cryptocurrency exchange, temporarily stopped withdrawals following Thursday’s attack. The company also announced that it would use its own funds to cover the losses caused by the incident.

How hackers reportedly targeted Binance

Binance co-CEO Richard Teng said on X that the complicated attack may have started after hackers gained access to a software engineer’s compromised laptop. This reportedly allowed them to enter systems used to process cryptocurrency withdrawals.

The company later discovered additional security breaches. Investigators also faced difficulties because software designed to remove traces of the attack made it harder to understand exactly what had happened.

Other major cryptocurrency exchanges quickly reviewed their security systems and reassured customers that their digital assets remained protected. A Kraken spokesperson said the company had full-time teams checking its systems every day for possible weaknesses.

Despite the scale of the incident, industry executives believe Binance has enough financial resources to cover the losses. They also expect the attack to have limited effects on the wider cryptocurrency market.

Bitcoin and other cryptocurrencies face pressure

The security incident also affected cryptocurrency prices. Bitcoin dropped by more than 4 per cent on Thursday, while Ether, the world's second-largest cryptocurrency, lost more than 5 per cent.

Both digital currencies recovered some of their losses on Friday. However, the incident raised fresh questions about the safety of cryptocurrency platforms and the risks facing investors.

“Our expectation is the industry writ large will actually not suffer material losses, even though Binance is obviously going to have to deal with the exploit directly,” said Josh Riezman, chief legal and strategy officer at crypto firm GSR.

According to US blockchain analysis companies TRM Labs and Chainalysis, most of the theft took place within around 20 minutes late on Thursday. The attack also showed similarities to earlier cryptocurrency thefts blamed on North Korea.

North Korea has repeatedly denied involvement in cryptocurrency thefts. Its mission in Geneva did not respond to requests for comment about the latest incident.

Social engineering adds to security risks

The exact method used by hackers is still unclear. However, security experts believe social engineering may have played a role in gaining access to the employee’s laptop.

Social engineering involves tricking people into sharing confidential information or giving criminals access to computer systems. Hackers often use fake messages, emails or other methods to deceive employees.

Harry Donnelly, chief executive of crypto risk infrastructure company Circuit, said cryptocurrency companies are planning more employee training. The aim is to help workers recognise suspicious activity and avoid giving hackers access to important systems.

The Binance hack has exposed serious security risks in the cryptocurrency industry. Even the world's largest exchanges can face major problems if hackers find weaknesses in their systems.

As digital currencies become part of mainstream finance, stronger security will be necessary to protect investors. Better employee training, regular system checks and information-sharing between exchanges could help prevent future attacks.

The biggest challenge for the industry is to build public trust. Without reliable security, more people may hesitate to invest in digital currencies.
