Incident Overview
19th of the April 2023 TalesofElleria was exploited for about $280,000 USD.
The exploiter minted 5,000,000,000 $ELM and drained the LP, looks like the private key or signing method was compromised. The attacker bridged 140 $ETH to Ethereum and transferred them to FixedFloat. He made 4 transactions to withdraw $ELM from the bridge.
Findings suspect that Ecrecover Function allowed the attacker to generate authorization signatures without TalesofElleria private keys.

What Auditors Should Check
If you're auditing a protocol with similar architecture to Tales of Elleria, these are the critical security checks that could have prevented this incident (April 2023).
- Verify all logic paths related to Access Control are guarded by proper access controls and input validation - see the Access Control Attacks attack class for patterns
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
