Crypto thefts have surged in the first half of 2025, with losses reaching approximately $2.47 billion, surpassing the total of $2.42 billion recorded for all of 2024. The majority of these losses stem from front-end protocol attacks and private key compromises, which account for around 80% of the stolen funds. Ethereum has been the most affected blockchain, with $1.5 billion lost across 164 incidents. Notably, the Democratic People's Republic of Korea (DPRK) was linked to a record $1.5 billion hack targeting the ByBit exchange. Decentralized finance (DeFi) platforms experienced the most attacks, while centralized exchanges (CEXs) suffered the largest individual losses. Emerging tactics such as AI-powered phishing, deepfakes, and fake Telegram verifications have become common tools for scammers. The top 10 exploits, rug pulls, and hacks alone accounted for over $2.4 billion in losses, highlighting persistent security vulnerabilities across the crypto ecosystem amid growing blockchain adoption.
