Exploit in Forge = $150 (+ $100 for publish and exploit in goerli)

Helper:
1. You can use the sample format https://github.com/sysfixed/forge_solidity_exploit_format_example (forge for virtual simulation transaction, don't forget to change the block that will be used)
2. You are asked to {save or exploit} liquidity before the dev (minimum 0.9 ETH from swap profits include fee)
3. A valid exploit must be executed in 1 transaction (at least you can run it in a virtual forge)
4. If the amount of liquidity decreases, you can still use the save block 8500065 "goerli" (the block after the Token Anak Bangsat contract is created)
5. Prizes are only given to the fastest, (can be 2 people because it's on virtual forge ($150) and published to goerli ($100))
6. Smart contract made in forge and goerli will allow different
7. To claim a prize, you must make a valid PoC first !

Clue:
1. You have to use Flashloan / Flashswap
2. Use your math logic

Example of a valid exploit result:
