Smart contract security auditor CertiK has received a $500,000 bounty for discovering a critical vulnerability in the Sui blockchain.
The company's team has reportedly noted that the bug, called HamsterWheel, is different from traditional exploits. According to them, a potential attacker could take over nodes and perform transactions without processing new transactions.
CertiK discovered the vulnerability before the release of the Sui mainnet last month. The developers immediately fixed the bug. The auditors have promised to publish a more detailed report at a later date.
CertiK's chief security officer, Kang Li, has said that methods for attacking blockchains are constantly evolving. The detection of HamsterWheel demonstrates the "evolving sophistication of threats," he has added.
The company has also stressed the importance of rewards programs for proactive cybersecurity efforts.
CertiK announced in May the freezing of $160,000 withdrawn from the decentralized Merlin exchange as a result of an exploit.
