The crypto sector experienced a significant loss of $127 million due to exploits and attacks during November 2025, primarily targeting Ethereum-based DeFi protocols and centralized exchanges. According to CertiK’s report, the losses were largely attributed to hacks and scams, with the figure exceeding attempted exploit attempts by over $172 million. The biggest impact was felt by Balancer Protocol, which faced over $113 million in losses due to vulnerabilities in its liquidity pool mechanics. This underscores the vulnerability of Ethereum-related and Layer 2 platforms. Other exchanges like Upbit also reported substantial breaches linked to known hacking groups. These incidents highlight the urgent need for stronger security measures as regulators prioritize enhanced protective strategies amidst a surge in sophisticated cyberattacks. Efforts are underway to recover some of the lost funds, with approximately $45 million restored through collaboration with law enforcement. The industry is grappling with the implications of these losses and continues to push for greater security protocols to mitigate risks. Past high-profile hacks serve as a reminder of recurring issues driving these losses.
