Crypto Hacks 2025: Over $2.4 Billion Stolen, Firms Affected

Blockchain security firm CertiK reports $2,472,777,618 in crypto stolen in 2025 through various hacks. This amount has already surpassed all losses recorded in 2024, marking a substantial increase in theft year-on-year.

CertiK outlines wallet compromises and phishing as primary attack vectors, with Ethereum and staked ETH being the most affected assets. A notable incident was the Bybit exchange exploit in February 2025, significantly contributing to the year’s total losses.

The aftermath of these incidents has weakened institutional and retail sentiment, leading to increased outflows from centralized exchanges. As noted in the Web3 Security Report Q1 2025, experts stated that $187 million in stolen crypto has been frozen or recovered, leaving net industry losses at approximately $2.29 billion.

Ethereum experienced the most significant impacts, with over $1.63 billion drained from 175 attacks in 2025. The Bybit hack particularly affected Lido Staked Ether, drawing comparisons between governance practices at different platforms.

The immense loss from the Bybit hack, totaling ~$1.45 billion, has sparked discussions about vulnerabilities within centralized exchanges. Regulatory and industry stakeholders have emphasized the need for improved security measures following this high-profile incident.

The hacking trend suggests potential financial and technological implications for the market. Calls for improved security practices, including bug bounty programs and formal audits, have resonated throughout the community. The market’s overall risk profile remains elevated despite a decrease in Q2 losses.

“The hacker–defender dynamic is endless,” said Ronghui Gu, CEO & Co-founder, CertiK, underscoring the constant escalation in cybersecurity risks.
