Name: WWII Code?By: RJCyber
Thehackerscrew are back! They have encrypted their message with a more advanced type of encryption.
We have intercepted this information in this specific order:Message: dvk{3ynxc@_1h_zd3_l@b_u0_u0}M3UKW BVII 3 2VII 16 3VIII 6 3eb ch af gd ij kp mn oz …
We have also found out that they have left out 4 plugboard partners. What does this mean?Flag format is RTL{flag}
Flag: RTL{3nigm@_1s_th3_w@y_t0_g0}
Writeup:The type of encryption used here is the Enigma Machine. The challenge is called “WWII Code,” since it was used by the Germans in WWII to send encrypted messages. Given are the different “settings” for cracking the code. The last 4 plugboard partners that are to be solved are “ut yw lq xv.” We can find these plugboards by focusing on the output text and substituting letters as needed. Having found this, the flag would then be decrypted to RTL{3nigm@_1s_th3_w@y_t0_g0}.
