A recent security breach has raised alarms in the Web3 community, affecting the newly launched payment protocol 402Bridge. The incident, which resulted in the theft of approximately 17,000 USDC, has impacted over 200 users and study highlights an alarming trend: the vulnerabilities that can arise in emerging blockchain technologies.
Exploit of 402Bridge
According to reports from blockchain security firm PeckShield, the exploit occurred just days after 402Bridge went live. The firm confirmed the breach and advised users to revoke any token approvals associated with the compromised contract address to mitigate further risks.
Design Flaw Acknowledged
The 402Bridge team acknowledged that the exploit was due to a critical design flaw in their backend process, which inadvertently granted administrative privileges to attackers. Blockchain investigators have traced the hacker's wallet address, revealing that the stolen funds were quickly converted into ETH and laundered through multiple cross-chain transactions.
Security Recommendations
In light of this incident, security experts are urging users to exercise caution by verifying contract addresses and avoiding unlimited token approvals. This breach serves as a stark reminder of the importance of robust security measures in the rapidly evolving landscape of blockchain technology.
On November 4, 2025, Ethereum achieved a remarkable milestone by processing 3,453 transactions per second, showcasing its evolving capabilities. This breakthrough contrasts sharply with the recent security breach affecting the 402Bridge payment protocol. For more details, see Ethereum's record.
