After a week of getting more and more frustrated i found a solution that i should have used the first time. But i'm fairly lazy. So for those who are still banging there heads against a wall, try the following for solving 25.2; Spoiler 1) Convert Hex to Bin 2) Open notepad and write out the Bin code on a line(s) 3) Write down the passphrase beneath the encrypted Bin code Spoiler Rolling XOR, where the precending, former Byte is the password of the next Byte 4) Decrypt on the next line by hand the encrypted code. Spoiler De-Cipher by example: Encrypt 0011 Passwrd 0101 Decrypt 0110 Following 0+0=0; 0+1=1; 1+0=1; 1+1=0 5) Convert solution to Text 6) Check Letter from Team 4 Spoiler "It is probably an instruction to Set the location for where to Dump sensitive information from infected machines." 7) Use solution.
