Lumi Finance, a protocol on Arbitrum, is facing an ongoing attack that has resulted in losses of about $270,000, according to Blockaid monitoring.
According to Foresight News, Blockaid said its analysis indicates the incident stems from a side effect involving token approvals generated during UserOp verification for Sodium smart accounts.
Blockaid said the attacker gained control of the paymaster/spender, obtained approval allowances from a large number of accounts, and then withdrew funds.
The incident is still ongoing, Blockaid said.
