KiloEx Suffers $7 Million Loss from Oracle Manipulation Attack

KiloEx, a decentralized exchange (DEX) for perpetual futures, suffered an attack resulting in losses of approximately $7 million. The exploit targeted the platform's price oracle system and affected multiple blockchain networks.

  • The attacker used a wallet funded through Tornado Cash to execute transactions on Base, BNB Chain, and Taiko networks.
  • A vulnerability in KiloEx’s price oracle system allowed manipulation of asset prices.
  • The breach led to the suspension of platform operations, with KiloEx collaborating to trace stolen funds and blacklist the attacker's wallet.
  • Oracles provide external data to blockchains, but can be vulnerable; in this case, the attacker exploited access control weaknesses to report false prices.
  • By reporting an artificially low price for ETH, the attacker created the illusion of significant profits which were withdrawn from KiloEx's vault.
  • In one transaction, the attacker gained $3.12 million.
  • This incident follows previous oracle manipulation attacks on other DeFi platforms like Mango Markets and Cream Finance, resulting in substantial losses.
