Crypto hacks soared to $2.24 billion in losses during the first half of 2025. Two significant events involved ByBit in February and Cetus Protocol in May, with considerable repercussions on Ethereum and Sui blockchains.
The surge in crypto theft highlights systemic vulnerabilities and necessitates enhanced security measures within the industry.
Major Hacks and Their Impact
ByBit suffered a record-breaking theft of $1.4 billion in February. The Lazarus Group is suspected of orchestrating this complex attack. By contrast, Cetus Protocol underwent a $225 million breach in May, though $162 million were successfully recovered.
The impacts on the market were significant, with Ethereum being heavily affected. These incidents have prompted a reevaluation of security practices across exchanges and blockchain networks given the significant assets at risk.
“While the overall figures are alarming, it is important to point out that the majority of the funds lost in H1 were attributable to two concentrated, high-impact events.” — Ronghui Gu, Co-founder, CertiK
Regulatory bodies might increase oversight following these events, compelling exchanges to adopt more robust security protocols. Industry alliances focus on collectively addressing these vulnerabilities.
Financial consequences were profound, though the community-driven recovery efforts suggest a path forward. The events are anticipated to drive regulatory scrutiny and the evolution of technical safeguards within the cryptocurrency sector.
