We do not know the facts in that case. But we urge everyone to be careful and check the website URL every time before starting any transaction related to financial transactions.

For the October 2022 incident, the vast majority of incidents were targeted to bridge-related protocols or platforms and protocols that use Oracles, SECURI LAB predicts that such incidents will recur. often This is because the protocol needs to retrieve the environment or various data through the oracles network for computation and comparison. If a smart contract is written that does not have a thorough check of execution or fuzzing, it may not be able to detect any mathematical flaws. Or various vulnerabilities, however, SECURI LAB would like to thank all readers and followers.
