Hacken: Web3 losses hit $3.95B in 2025 as North Korea-linked theft and weak keys dominate

Hacken's 2025 Yearly Security Report estimates Web3 losses at about $3.95 billion, up roughly $1.1 billion from 2024, with North Korea-linked clusters responsible for around half of the stolen funds. The Bybit breach of nearly $1.5 billion and widespread access control failures drove most losses, while regulators in major jurisdictions outlined security expectations that many Web3 firms still failed to implement.
