As the crypto industry continues to grow and evolve, a new threat has emerged that is causing concern among investors and security experts alike. According to a recent report by blockchain security firm CertiK, phishing scams have become the most significant security threat in 2024.

The Dangers of Phishing Scams

Phishing attacks involve hackers sharing fraudulent links with victims to steal sensitive information, such as crypto wallet private keys. These types of attacks are particularly effective because they often appear legitimate and can be difficult for even experienced investors to spot.

CertiK’s Annual Web3 Security Report

According to CertiK’s annual Web3 security report, published on January 2nd, phishing attacks were the most costly attack vector in 2024. The report states that over $1 billion worth of stolen digital assets were lost across 296 incidents.

The Scale of the Problem

But what’s particularly alarming is that out of these 296 incidents, at least three resulted in losses exceeding $100 million. This highlights the scale of damage possible when phishing scams succeed.

In May, a trader lost $68 million worth of crypto in a single transaction due to an address-poisoning incident. Address-poisoning involves tricking victims into sending their digital assets to fraudulent addresses belonging to scammers. Fortunately, in this case, the unknown attacker returned all the stolen funds after 10 days, likely due to pressure from heightened attention by blockchain security firms.

Private Key Compromises: A Growing Concern

Private key compromises were the second-largest threat after phishing scams, resulting in over $855 million worth of stolen crypto across 65 incidents in 2024. According to CertiK’s report, phishing tactics will certainly evolve in 2025, especially as AI develops.

A Year-Over-Year Comparison

Despite the growing threat of crypto phishing scams, the yearly amount of crypto hacks was still down 52% from the $3.5 billion stolen during 2022, according to CertiK’s report. This is a positive trend, but it’s essential for investors and security experts to remain vigilant.

Measures Against Phishing Attacks

Industry participants are already taking measures against phishing attacks. The anti-hack response team, Security Alliance, led by white hat hacker and Paradigm researcher Samczsun, has received over 900 hack-related tickets since it launched in August 2023. Binance’s security experts have also developed an "antidote" against the growing instances of address poisoning scams.

The Impact on the Industry

Beyond phishing incidents, crypto hacks cost the industry over $2.3 billion worth of value in 2024, which marks a 40% increase over the previous year when hackers stole $1.69 billion worth of crypto, according to a report shared by onchain security firm Cyvers.

Conclusion

Phishing scams are a growing concern for the crypto industry, and it’s essential for investors and security experts to remain vigilant. By understanding the risks and taking measures to prevent phishing attacks, we can work towards creating a safer and more secure environment for all participants.
