EVM - Bytecode

Elf — 2025-03-14T08:49:32Z

Your colleague has a "brilliant" idea : ditching password managers in favor of a smart contract on Ethereum to verify passwords. You warn him it's a terrible plan, but he insists : “I didn't publish the source code on Etherscan, so no one can steal my password.”

Time to show him the harsh reality with a practical demonstration.

Address of the smart contract on the Sepolia testnet : 0x6028Ee769D519A92bc5db0210C2cC34c6d178b93

You and your team are preparing a pwn challenge in Rust for your next CTF.
You discover by coincidence a member of your team in a call in the toilets, who seems to be talking with a participating team about a backdoor he has placed in the challenge to allow them to flag without anyone knowing !

Pissed off, you decide to reveal his plans to everyone.
Find out how to trigger the backdoor.

NRO ARM - Switch homebrew

Elf — 2023-07-21T15:01:20Z

Your friend developer, owning a Mariko Switch and knowing that yours is vulnerable to fusée gelée, asks you to test the alpha of his latest homebrew, in order to get user feedback on a real console rather than an emulator. So as to make sure that the fruit of his labor cannot leak, he also informs you that he has protected it with a PIN code.

Skeptical about the usefulness of this protection and because you like challenges, you tell him that there is no need for him to give you the PIN code to try his game and start rolling up your sleeves.

Unity - IL2CPP - Basic Game Hacking

0x0ff — 2023-07-21T15:01:00Z

Runlevel0 is a horror game in three levels in which you will find the pieces of a sentence.

This reconstructed sentence is the flag that allows you to validate this test.

Each level may be solved with a different method.

Good Luck !

The validation sentence starts with a capital letter and ends with a period. The three pieces of sentences found in the different levels are to be separated by commas.
Example :

level 1 : Once upon a midnight dreary
level 2 : while I pondered
level 3 : weak and weary
Flag/Solution : Once upon a midnight dreary, while I pondered, weak and weary.

PS : You'll need the sound
