Incident Overview
The DecentraWorld project was successfully rugpulled by its project team. At that time, projet's $DEWO token showed a positive development trend until the team drained out all the treasures from the project, stealing more than $1m.
The DecentraWorld token $DEWO was created in this transaction (https://bscscan.com/tx/0xb8ff69cf…36faf7), where 100m tokens were minted to the address of the creator. The deployer's address accumulated transactions fees and tax from each transaction, as well as part of the tokens remained at the same address after minting, and when the price became attractive enough, the DecentraWorld project team sold tokens for $WBNB through the PancakeSwap (https://bscscan.com/tx/0x94018528…816f66).
As the time of this writing information on this case is scarce. More sources will be added if the case should develop.

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 DecentraWorld, these are the critical security checks that could have prevented this incident (May 2022).
- 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
