The Midnight Foundation has released an official update on the response to the attack on Wanchain's Cardano-BNB cross-chain bridge . The developers quickly brought partner exchanges into the investigation: Binance, OKX, Kraken, KuCoin, Bybit, Gate, and MEXC introduced emergency measures to completely block the movement of the stolen funds. Advertisement The coordinated response from the platforms prevented the liquidation of 515 million NIGHT tokens, worth approximately $9 million, stolen from the treasury of a third-party smart contract. Following the incident, NIGHT temporarily plunged by more than 30% on decentralized exchanges, reaching an all-time low of $0.016.

At the foundation's request, the exchanges immediately blacklisted the attacker's wallets, temporarily froze associated accounts, and suspended NIGHT deposits and withdrawals. Advertisement This prevented the hacker from laundering most of the stolen funds. However, the attacker managed to sell approximately 290 million tokens on Cardano decentralized exchanges, where automated freezes are impossible, causing the short-term price collapse.

The incident was not caused by a systemic failure within either project, and the vulnerability was isolated exclusively within the Wanchain bridge code, which had been operating for approximately two years. According to analysts at BlockSec's Phalcon platform, the hacker exploited a flaw in the TreasuryCheck validator . The contract verified 14 data fields placed consecutively without delimiter characters. Advertisement The attacker took a legitimate BNB Chain signature intended for a transfer of just 3,110 NIGHT and, due to the absence of clear boundaries between the data fields, reused it on the Cardano side, inflating the transaction by 65,000 times to 203 million NIGHT in a single operation.

However, the main challenge remains the resulting imbalance: after the Cardano treasury was drained, wrapped NIGHT tokens on BNB Chain were temporarily left without collateral backing. The Midnight Foundation is continuing its investigation and has urged the community to rely only on official communication channels to avoid phishing attempts during the incident response. #Cardano News #Cardano Midnight
