Beosin: Sonne Finance protocol attacked, resulting in a loss of approximately 20 million dollars - incident analysis
According to ChainCatcher news, Beosin Alert monitoring has discovered that the Sonne Finance protocol on the OP chain has been attacked by hackers using a flash loan attack, resulting in approximately $20 million in losses due to multiple attacks.
The Beosin security team analyzed that the attackers borrowed VELO Tokens through flash loans and sent them to the soVELO contract via transfer, repeatedly creating new contracts to borrow various tokens from the Sonne Finance protocol and redeem VELO Token tokens. This operation was repeated until all funds were drained.
Currently, the attackers are mainly holding the funds at the following addresses:
0x02FA2625825917E9b1F8346a465dE1bBC150C5B9
0x5D0D99e9886581ff8fCB01F35804317f5eD80BBb
0xae4A7cDe7C99fb98B0D5fA414aa40F0300531F43
Beosin Trace will continue to monitor the movements of the stolen funds.
