It appears the attacker was able to manipulate their Mango collateral. They temporarily spiked up their collateral value, and then took out massive loans from the Mango treasury. pic.twitter.com/2IJrB9RcEJ— OtterSec (@osec_io) October 11, 2022

What else is known about the incident? OtterSec said that the exploit was committed by manipulating the price oracle and inflating the real value of MNGO tokens. By inflating the value of the collateral, the attackers took out a loan for a large amount and drained the liquidity pools.

Representatives of the platform confirmed the hack on their Twitter, adding that they have already launched an investigation into the incident. They are currently taking steps to freeze the stolen and withdrawn funds by third parties. The platform’s depositing feature has been temporarily disabled for security purposes.
