Root-Me reachable over IPv6

4 January 2015

Root-Me made a big step forward and has now one foot in the IPv4 world and an other in the IPv6 hot and shiny one. The other good news is that you don’t have to do anything: it should just work with or without IPv6 support on your side.

Very few but some challenges remain IPv4 only though. The CTF AllTheDay architecture is ready for IPv6, but most of the CTF Virtual Machines are not and until we fix them, CTF will continue to be an IPv4 only thing (hopefully it won’t stay so for to long).

A big thanks to the team and especially to spump for the work behind this !


Public solutions and cheating

29 November 2014

Due to a lot of abuse, and in order to clarify the situation, the legal disclaimer page has been modified; we invite you to consult it regularly.

Root me already offers to share your solutions with other players directly on the website, while not "spoiled" those who have not yet solved the challenge.

These rules should allow us to keep together an emulation’s spirit while continuing to learn infosecurity in a fun way.


crypto/transposition - rail fence challenge modified

18 May 2014

The cryptanalysis challenge "Transposition — rail fence" suffered from two main problems:
- key was badly chosen and the challenge was a corner case of the algorithm
- the cleartext was the result of an encryption instead of decryption as one would normally expect: this is against the philosophy behind this plateform, especially for easy challenges

The challenge has thus been rectified, previous validations were reset. Submitted solutions have also been removed as they were not correct but working for the corner case.

Thanks for your understanding!
