Time Hack
Incident Overview
Time token, an ERC20 token on Ethereum, suffered a price manipulation exploit on Dec 6, 2023, resulting in a loss of 94 ETH or $200,000 USD.
On December 6, 2023, Time token was exploited due to a smart contract vulnerability that allowed price manipulation via a public burn issue and vulnerable ERC2771 standard. The attacker exploited the vulnerable Forwarder contract and was able to drain funds from the DEX by burning TIME tokens to inflate the token price and take away rewards. The exploit resulted in a loss of 94 ETH, equivalent to approximately $200,000 USD.
Thirdweb, the deployer of the TimeToken contract, had issued a community alert regarding the security vulnerability on December 5th, 2023, following an internal disclosure on November 20, 2023. Users who deployed impacted pre-built smart contracts before November 22, 2023, at 7 PM PST need to take specific mitigation steps to address the vulnerability identified by Thirdweb. The stolen funds are currently at the malicious contract.

What the Attacker Needed to Succeed
Understanding the prerequisites for this type of attack helps auditors identify protocols that are most at risk and helps developers build better defenses.
What Auditors Should Check
If you're auditing a protocol with similar architecture to Time, these are the critical security checks that could have prevented this incident (December 2023).
- Verify all logic paths related to Other are guarded by proper access controls and input validation
- Review privileged functions (owner, admin, governance) for potential abuse vectors - centralization risks should be documented and bounded with timelocks or multi-sigs
