Briefings

In November 2025, a 12-person Arbitrum council committee rewrote a core contract to spend funds from an address it did not hold access to, then reverted the change. This occurred after the hacker who breached the system previously held the necessary key. The event is the second instance of this unauthorized spending mechanism in 2025.

Key points

• A 12-person committee rewrote a core contract to spend funds from an address it held no key for, then reverted the change.
• This was the second time this unauthorized spending mechanism occurred in 2025.

Context

Arbitrum is a Layer 2 scaling solution for Ethereum. The hack involved a breach where a hacker previously held the key to access funds, but the council bypassed this requirement to spend the stolen money.

Limitations

Evidence is limited to a single incident from November 2025. No specific dates for the hacker breach or the subsequent contract rewrites are provided. The source does not specify the total amount of funds spent or the final outcome of the revert process.
