The protocol abandoned three years ago can still be exploited for $2.1 million; this revelation is more intriguing than expected.

Wu has learned that Ethereum privacy infrastructure developer Aztec Labs is investigating a security incident that may affect the Aztec Connect protocol, which has been discontinued. Approximately $2.1 million worth of assets have been transferred out of the related non-upgradable smart contracts. Aztec Connect was deprecated three years ago, and Aztec Labs does not hold administrative privileges nor can it pause or upgrade the system. The team stated that they will disclose more updates on the investigation later.
