How to Win 10 Million Satoshi by Hacking TimeLock V3.3
If you are a skilled hacker who loves a challenge, you might be interested in trying to crack TimeLock V3.3, a program that allows users to time-lock any digital content using the Bitcoin blockchain. The creator of TimeLock, u/cryptocomicon, has posted a reward of 10 million Satoshi (about $600) for anyone who can hack his program and access a private key stored in a lock box.
TimeLock is a free software that lets you encrypt any file up to 10 KB and set a time interval for when it can be decrypted. The decryption is based on the timestamp of the Bitcoin blockchain header, which means that you cannot access the file before or after the specified time. This can be useful for creating time capsules, digital wills, or secret messages that can only be revealed at a certain date.
The latest version of TimeLock, V3.3, has been released on February 9th, 2020, and it comes with a hacking challenge from its developer. He has created a lock box with a private key worth 10 million Satoshi and posted all the information you need to get started on his website: https://www.algomachines.com. The lock box can only be opened via TimeLock between February 9th and March 9th, 2020. The only thing protecting the reward is the Bitcoin blockchain timestamp and the ability of TimeLock to withstand your hacking attempts.
This is not the first time that u/cryptocomicon has issued such a challenge. He has done it ten times before, and each time his program was hacked by some brilliant hackers who managed to find vulnerabilities in his code. You can read their reports on his website and learn how they did it and how TimeLock works.
Some of the changes that he has made to TimeLock V3.3 compared to the previous version are:
UI only allows one lock box open per session
Obscure encrypted strings as they are loaded to the interpreter
Improved interpreter anti-debugging measures
Interpreter code obscure
If you think you have what it takes to hack TimeLock V3.3 and claim the 10 million Satoshi reward, you can download the program from his website and start your attack. You can also join the discussion on Reddit: https://www.reddit.com/r/CryptoCurrency/comments/el3qe8/timelock_v33_10_million_satoshi_hacking_challenge/ and share your progress or ask for help.
Good luck and happy hacking!
What is TimeLock and how does it work
TimeLock is a program that uses cryptography and the Bitcoin blockchain to create time-locked files that can only be decrypted during a specified time interval. The program is written in C++ and runs on Windows, Linux, and Mac OS.
To use TimeLock, you need to have a file that you want to encrypt and a password that you want to use for decryption. You also need to choose a start time and an end time for when the file can be decrypted. The start time and the end time are expressed in UTC and must be within the range of the Bitcoin blockchain header timestamps.
When you encrypt your file with TimeLock, the program will generate a lock box file that contains your encrypted file and some metadata. The metadata includes the start time, the end time, the hash of the password, and the hash of the Bitcoin block header at the time of encryption. The lock box file can be shared with anyone, but it can only be opened by someone who knows the password and has access to the Bitcoin blockchain.
To decrypt your file with TimeLock, you need to have the lock box file, the password, and a connection to the Bitcoin network. The program will check the current timestamp of the Bitcoin blockchain header and compare it with the start time and the end time stored in the lock box file. If the current timestamp is within the time interval, the program will verify the password and decrypt the file. If the current timestamp is outside the time interval, or if the password is incorrect, the program will not decrypt the file.
TimeLock uses a custom encryption algorithm that combines AES-256 and SHA-256. The encryption key is derived from the password and the hash of the Bitcoin block header at the time of encryption. The encryption algorithm is designed to be resistant to brute-force attacks and quantum computing. aa16f39245
