The latest breach highlights growing risks from deprecated smart contracts holding legacy assets in decentralized finance.
Aztec Network lost $2.1 million in a second smart contract exploit within a week, according to blockchain security firm SlowMist. The attack targeted deprecated infrastructure still holding user assets, despite the protocol no longer being maintained.
The incident follows a $1.3 million theft from decentralized exchange Raydium earlier in June, both stemming from vulnerabilities in abandoned smart contracts. Security analysts warn that unmigrated legacy assets create persistent attack surfaces for hackers.
SlowMist recommended protocols with deprecated contracts conduct orderly asset migrations to eliminate ongoing cybersecurity risks. The exploits have reignited concerns about the security of outdated blockchain infrastructure in DeFi ecosystems.
