HKAN | Aug 27

According to blockchain security firm Certik, the crypto industry has already seen over $2.47 billion stolen via hacks in 2025. The figures cover multiple attacks on exchanges, DeFi protocols, and NFT platforms, signaling that cybersecurity remains a top concern for the rapidly growing digital asset market.

Notable Insights from the Report

• Decentralized Finance (DeFi) platforms accounted for a significant portion of the losses.

• Exploits and smart contract vulnerabilities remain the most common attack vectors.

• Centralized exchanges also faced breaches, emphasizing that no sector of crypto is entirely immune.

Certik emphasized that while the total theft volume is staggering, it represents a slight decrease compared to the same period in 2024, suggesting that some security measures are improving, but the threat landscape remains highly active.

The Importance of Security

Experts urge crypto investors to:

• Use hardware wallets for large holdings.

• Diversify holdings across platforms.

• Monitor updates on smart contract audits and security patches.

“While blockchain is inherently secure, user practices and protocol vulnerabilities continue to create opportunities for hackers,” Certik noted.

The report underscores the need for stronger security protocols, auditing services, and regulatory guidance to protect both institutional and retail investors.

As crypto adoption grows, ensuring the security of digital assets will be critical to sustaining trust and preventing further multi-billion-dollar losses.
