Nine Chainlink node operators were subjected to so-called "spam attacks." The attackers obtained approximately 700 ETH (worth approximately $335,000 at the time) from their "hot wallets". Oracles like Chainlink feed data on to blockchain smart contracts via node operators. This is because smart contracts, by design, cannot communicate with external systems. Node operators get rewarded for their work. Chainlink, for instance, pays them in its native token LINK. The malicious actor could successfully perform the attack by using operators' spare gas to mint Chi gas tokens, which are created by decentralized exchange aggregator 1inch.Exchange. Most of the affected node operators continued refilling their nodes "because they thought it was due to the gas spike that night" and the refilled ETH was also getting drained.
