socket, a blockchain interoperability protocol, disclosed a breach that resulted in over $3.3 million in losses. This exploit, due to a flaw in user input validation, targeted wallets that granted infinite permissions to socket contracts. This vulnerability enabled unauthorized fund transfers and highlighted the importance of strong security measures in the evolving decentralized finance (DeFi) environment.
Disclosed Vulnerability: Exploited Flaw
Blockchain security company PeckShield said the security breach was linked to a specific path within the system that was added three days before the attack. This path, which is critical to the Bungee bridging collector, had an input validation flaw that allowed the protocol to be exploited. Following the incident, Socket immediately disabled the offending path to prevent further misuse.

Socket Response and Mitigation Measures
Sockets responded immediately to the breach, acknowledging a vulnerability in user input validation. In an effort to mitigate the impact and protect user assets, affected contracts have been temporarily suspended. Socket assured its user base that no further action was needed, emphasizing its commitment to protecting the interests of the community.
Identify root cause
Cybersecurity firm Hacken confirmed that the vulnerability originated from a recently deployed contract. A flaw in user input validation allowed attackers to manipulate unauthorized fund transfer contracts. Socket’s vigilance in identifying and resolving root causes highlights the ongoing challenges of maintaining smart contract security as DeFi platforms evolve.
