$25.4M Lost to Crypto Hacks in First Week of September
Over $25M was lost to crypto hacks in early September, with $14.4M recovered or frozen, according to CertiK.

- $25.4M lost in crypto hacks during the first week of September.
- $14.4M of the stolen funds were recovered or frozen.
- September shows better recovery rates than July and August.
In just the first week of September 2025, the crypto world saw losses totaling $25.4 million due to various hacks and exploits, according to blockchain security firm CertiK. These figures highlight the persistent security challenges facing the crypto industry, even as protocols and platforms continue to upgrade their defenses.
While the volume of losses is alarming, it’s not unusual in the world of decentralized finance (DeFi), where vulnerabilities in smart contracts, bridge protocols, and private key management remain common entry points for attackers.
Improved Recovery Efforts in September
Despite the major loss, there’s a silver lining—$14.4 million of the stolen funds were either recovered or frozen. This marks a significant improvement in post-hack fund recovery compared to the previous months. For context, July and August saw far lower recovery figures, making this a notable shift in response efforts.
CertiK’s report credits this to better real-time tracking, quicker coordination between exchanges, and improved community reporting tools. These advancements have enabled faster responses that can prevent stolen assets from being laundered or moved to hard-to-trace platforms.
Security Still a Major Concern
Even with stronger recovery operations, the fact that over $10 million remains unrecovered highlights the ongoing risks associated with crypto investments. As DeFi continues to grow, so too do the incentives for malicious actors. This places even more responsibility on developers and users to follow best security practices, including audits, bug bounties, and using reputable platforms.
With four weeks still left in the month, the industry will be watching closely to see whether September becomes another high-loss month, or a turning point in improving security responses.
