the 13/05/2018 at 04h09# 03 Hey, i'm stuck with this challenge. I can change some parts of the plaintext but because i dont know the format of the obj that goes into the encrypt function i dont know what exactly i am changing. Could you clarify what the format of the obj that goes into encrypt is, maybe with an example? Or is the format of obj not important? Also, what exactly is the goal of the challenge? Is it really to get a shell like mentioned in the description? Or is it to change the Login name to "admin"? |

the 22/07/2018 at 23h12# 04 The goal is to spawn a shell. This challenge has a bit of hacking in addition to crypto. The exact format of object is unimportant. What values do you know must be contained in the object? What do you know about the encoded object? |
