Binance Oracle bug vulnerability, suspected to have been exploited by a studio to farm hundreds of accounts

Since Oracle’s data comes from the Predict prediction market,
arbitrageurs first place orders on Predict,
then Oracle mirrors those orders in the system.
Because liquidity is low, arbitrageurs can control order book prices,
allowing them to buy low and sell high on Oracle.

🔶 The Binance team said it is investigating and handling the matter.

I think the difficult part is figuring out how to identify abnormal accounts.
Accounts that earn a large number of points in a short time can be prioritized.
But if they farm only a few points—just enough to make the cutoff for the consolation ranking—how can they be identified?
If regular users place normal orders and get matched with the studio’s low-priced orders, should they be penalized?

Checking accounts on a large scale could take a lot of time.

To solve this problem at its root,
either Oracle needs its own pricing (technically complex, and Oracle only has one week left),
or orders in low-liquidity markets and at extreme prices need to be restricted.

Otherwise, the system will continue to be exploited.
