CertiK has reported a substantial $2.5 billion in cryptocurrency thefts in the first half of 2025. The losses, largely attributed to wallet compromises and phishing campaigns, underline the vulnerabilities present in current blockchain technologies.
Ronghui Gu, co-founder of CertiK, emphasized the “endless war” against hackers. As a well-regarded authority in blockchain security, Gu notes the necessity for proactive measures to counteract relentless threats to digital assets.
“As long as there’s a weak point or some vulnerabilities out there, sooner or later they will be discovered by these attackers… So it’s an endless war.” — Ronghui Gu, Co-founder, CertiK
Major hack incidents have notably affected the Ethereum (ETH) and Bitcoin (BTC) networks. The reported breaches, including high-profile attacks on Bybit and Cetus Protocol, have led to increased scrutiny and concern within the crypto community.
The financial repercussions are significant, affecting liquidity in DeFi markets and shaking investor confidence. Despite some recovery efforts, approximately $2.2 billion remains unrecovered, deepening the impact on crypto ecosystems.
CertiK’s findings, supported by historical analysis, suggest the continuation of security vulnerabilities in DeFi and traditional ecosystems. Industry experts advocate for enhanced security systems and multi-layer authentication to mitigate potential future threats.
Insights from CertiK highlight the pressing need for robust security frameworks. Phishing remains a major attack vector, warranting immediate and sustained efforts to strengthen individual and organizational safeguards against cyber threats.
