Over $2 billion has been stolen through crypto hacks and exploits in the first half of 2025, per reports. Unlike older tactics like phishing, this year's hackers use AI-assisted tools to scan smart contracts for vulnerabilities, and further execute precision-based attacks.
Decentralized finances (DeFi) remain the most targeted sector among hackers, followed by NFT marketplaces. Security auditors are struggling to keep up with the ever evolving tactics of these scammers, thus prompting calls for AI-driven, real-time threat monitoring.
Meanwhile, state-sponsored groups like North Korea's Lazarus Group which attacked Dubai based exchange Bybit in March this year, are suspected in high-profile breaches. With growing popularity of cross-chain protocols, vulnerabilities keep increasing, and there is no saving grace in sight, at least, not yet.
Experts warn investors to use cold wallets, and avoid patronizing untested DeFi platforms. It is no longer enough to be cautious, cryptocurrency users must now be proactive and highly informed, in order to have their funds well secured.
