Halfway through 2025, the crypto industry has already suffered over $3.1 billion in losses from hacks, scams, and exploitations.According to Hacken’s latest report, this year has emerged as one of the most damaging in recent memory.Access-Control Exploits Dominate LossesThe latest figure surpasses last year’s $2.85 billion by over 6%, as security lapses across the sector continue. In a statement, Hacken Co-Founder and CBDO Yevheniia Broshevan said,“2025 has been a wake-up call. In just two quarters, $3.1 billion was lost to access control failures, DeFi vulnerabilities, and social engineering. As blockchain reaches enterprise scale and regulations advance, cybersecurity becomes a core business function. Projects that invest in resilience and security build trust, meet compliance, and protect digital innovation.”The single largest incident was the Q1 Bybit hack, where attackers drained nearly $1.5 billion. The incident alone accounted for 83% of Q1’s total losses and highlighted the catastrophic risks tied to compromised access control systems.In total, access-control exploits dominated the landscape and were responsible for about 59% of all funds lost, approximately $1.83 billion, across DeFi and CeFi platforms.DeFi Suffers Worst Quarter Since 2023DeFi suffered its worst quarter since early 2023, with $300 million drained in Q2 alone. Smart contract flaws played a crucial role, as this cohort accounted for 8% of total crypto losses and led to $263 million stolen, including $223 million in the major Cetus exploit this year.Phishing and social-engineering scams also surged to new records. In fact, a single incident in April saw a victim lose $330 million in Bitcoin after being tricked, while phone-based scams mimicking Coinbase support drained over $100 million following a contact data leak.While Q1 was marred by large-scale access control failures, Q2 was comparatively quieter. The period witnessed under $200 million lost to similar exploits, yet several high-profile incidents showed how a single overpowered role or leaked key can enable attackers to drain systems within minutes.The post $3.1 Billion in Crypto Lost in 2025’s Painful First Half: Hacken appeared first on CryptoPotato.
