Crypto Hacks and Scams Top $3.35B in 2025
Losses from crypto hacks, scams, and exploits surpassed $3.35 billion in 2025, according to CertiK's latest report.
- CertiK reports $3.35B lost to crypto-related incidents in 2025
- Hacks, exploits, and scams remain a major threat to Web3
- Urgent need for better blockchain security and awareness
According to a new report from blockchain security firm CertiK, total losses from crypto hacks, scams, and exploits in 2025 have exceeded $3.35 billion. The staggering figure highlights the ongoing vulnerabilities within the crypto ecosystem, especially in decentralized finance (DeFi) protocols, NFT platforms, and cross-chain bridges.
Despite increased awareness and improved security tools, malicious actors continue to find new ways to exploit both technical loopholes and human error. This marks a significant concern for investors, developers, and regulators alike as the Web3 space matures.
Breakdown of the Incidents
CertiK’s report outlines that the majority of losses came from protocol exploits and phishing scams. Notably, flash loan attacks and vulnerabilities in smart contracts were responsible for hundreds of millions in losses. Meanwhile, rug pulls and social engineering scams also played a major role in draining funds from unsuspecting users and investors.
Compared to 2024, the total losses show a concerning increase, indicating that while innovation continues, security measures are struggling to keep pace.
Security Still a Work in Progress
As Web3 adoption grows, the importance of robust security practices cannot be overstated. CertiK and other security platforms urge developers to undergo rigorous audits, adopt real-time monitoring, and educate their communities. For users, staying informed and vigilant is critical.
Experts suggest that better regulatory oversight and insurance models may help mitigate the impact of such attacks in the future. Until then, the $3.35B loss serves as a stark reminder that crypto still carries significant risks.
