bee-san/Ares https://github.com/bee-san/Ares
Wed 28 Dec 2022 05:52:50 PM PST archive.org

Automated decoding of encrypted text without knowing the key or ciphers used. Ares is the next generation of decoding tools, built by the same people that brought you Ciphey. We fully intend to replace Ciphey with Ares.

Ares is fast. Very fast. Other decoders such as Ciphey require advance artifical intelligence to determine which path it should take to decode (whether to try Caesar next or Base64 etc). Ares is so fast we don't need to worry about this currently. For every 1 decode Ciphey can do, Ares can do ~7. That's a 700% increase in speed.

There are 2 main parts to Ares, the library and the CLI. The CLI simply uses the library which means you can build on-top of Ares.

Ares currently supports 16 decoders and it is growing fast. Ciphey supports around ~50, and we are adding more everyday.

At the beginning of 2020, we discovered the Red Unlock technique that allows extracting Intel Atom Microcode. We were able to research the internal structure of the microcode and then x86 instruction implementation. Also, we recovered a format of microcode updates, algorithm and the encryption key used to protect the microcode.

This is the tools they used to take it apart.

Chepy is a python library with a handy cli that is aimed to mirror some of the capabilities of CyberChef. A reasonable amount of effort was put behind Chepy to make it compatible to the various functionalities that CyberChef offers, all in a pure Pythonic manner. There are some key advantages and disadvantages that Chepy has over Cyberchef. The Cyberchef concept of stacking different modules is kept alive in Chepy.

GitHub - gchq/CyberChef: The Cyber Swiss Army Knife - a web app for encryption, encoding, compression and data analysis https://github.com/gchq/CyberChef
Thu 26 Mar 2020 04:18:02 PM PDT archive.org

CyberChef is a simple, intuitive web app for carrying out all manner of "cyber" operations within a web browser. These operations include simple encoding like XOR or Base64, more complex encryption like AES, DES and Blowfish, creating binary and hexdumps, compression and decompression of data, calculating hashes and checksums, IPv6 and X.509 parsing, changing character encodings, and much more.

The tool is designed to enable both technical and non-technical analysts to manipulate data in complex ways without having to deal with complex tools or algorithms. It was conceived, designed, built and incrementally improved by an analyst in their 10% innovation time over several years.
