What happened

Hundred Finance lending protocol was affected due to the Meter bridge exploit.

The exploiter of Meter.io dumped BNB.bsc assets several times at:

https://moonriver.moonscan.io/tx/0x14dc9ed2…9be504

https://moonriver.moonscan.io/tx/0x4afa30ee…ab63bf

https://moonriver.moonscan.io/tx/0x5a87c24d…ee0591

https://moonriver.moonscan.io/tx/0x9d662396…cf966d

https://moonriver.moonscan.io/tx/0x4e2a54f3…2a2156

https://moonriver.moonscan.io/tx/0xbe0610f8…f601ad

That resulted in the local depreciation in the price of BNB.bsc. Different external addresses were able to purchase BNB.bsc at a reduced price and use these tokens as collateral at the global Chainlink price to borrow uncompromised assets on Hundred Finance. As a result, MIM and FRAX tokens were impacted.
