Wanchain Cardano Bridge Exploited, $10M NIGHT Stolen

The Wanchain Cardano-to-BNB Chain bridge was exploited, draining about 515.2 million NIGHT from the Cardano-side treasury and triggering a sharp drop in NIGHT’s price, with BlockSec pointing to a possible signature-reuse vulnerability in the TreasuryCheck validator. The Midnight Foundation and investigators say the core Midnight network remains secure and that the issue lies with third-party bridge infrastructure, while the investigation is ongoing and multiple analyses point to an encoding flaw that could allow different data to produce the same signed message.
