Incident Overview
BIGTIME token was rugpulled on Oct 13, 2023 worth 168,699 USD
BIGTIME is a BEP20 token trading on PancakeSwap. The scammer received 0.055 BNB from Binance before the incident and then swapped BIGTIME tokens to WBNB. The stolen funds (819.9 BNB, equivalent to 168,699 USD) were transferred to another EOA and then distributed among multiple addresses.
The scammer is not directly related to the deployer, but most likely the contract was intentionally written with a backdoor function, allowing the scammer to increase their balance by sending tokens to themselves.

What Auditors Should Check
If you're auditing a protocol with similar architecture to Big Time, these are the critical security checks that could have prevented this incident (October 2023).
- Verify all logic paths related to Rugpull 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
