Crypto frauds and hacks continue to challenge the industry, despite significant improvements in blockchain security. A recent report revealed that Q2 2026 recorded 83 crypto hacks, making it the most-exploited quarter on record, as attackers targeted DeFi protocols, smart contracts, bridges, and user wallets. Security measures such as audits, bug bounty programmes, and AI-powered threat detection have become more common, yet cybercriminals continue to adapt. As the crypto ecosystem grows, can innovation outpace increasingly sophisticated attacks, or will security always remain the industry's biggest challenge?
Q2 2026 witnessed one of the highest numbers of DeFi exploits on record, with hackers continuing to target bridges, smart contracts, and protocol vulnerabilities. While security audits and bug bounty programmes have improved over the years, billions of dollars have still been lost to DeFi hacks. Is this simply the cost of building an open financial system, or does the industry need to rethink how decentralised applications are secured?
