The Challenge In Detection
Because of the interconnected nature of numerous DeFi platforms and rate oracles, it can be challenging to find and avoid control attacks on these systems.
Security treatments, such as multi-signature authentication and information confirmation techniques, need to be carried out by DeFi platforms and prices oracle service providers to minimize the probability of these attacks.
Official message to the assaulter:
At 8am UTC 1 May 2023 the police procedure is set up to start in the lack of any funds being returned.
We will take the leads we’ve gotten up until now (thank you to the general public for these), integrate it with our tracing we’ve currently done on…
