Signal 5 => 368 Welcome back to the 80s! In the 80s there was no such things like Signal or Telegram. We had different, ancient means to communicate. Sometimes even the physical layer of the communication stack was...unusual! But you may not care, because you came for the flags! Come for the flags, stay for the hack! Right? You see, we wish we could just plant a simple flag, but we thought...what a boooring idea! So we decided to go a bit different for this challenge. Instead of hiding the complete flag as is, we splitted it into many parts. Once you find all the parts, you must concatenate them sequentially using an underscore character "_" as a separator. The final flag will look like this: TMCTF{part1_part2_..._partN} Feel free to keep TMCTF{ and the trailing } out of the flag: the system will accept a flag with or without those. We don't remember how many parts we hid in the challenge, sorry, so we can't really help: you just follow the leads and you'll find them all! :-) Exactly same challenge as D:\_proj\_CTS\HWIO_2021_CTS\Signal5 (not solved in time) Final Flag ?: TMCTF{SOS-STEGHIDE-TOOL-F1N1CKY5HUT_4TH#CHAN#FROM#LEFT#SYNC#7A_TheMouseJigsawRefillCoolEOF} SOS-STEGHIDE-TOOL-F1N1CKY5HUT_4TH#CHAN#FROM#LEFT#SYNC#7A_TheMouseJigsawRefillCoolEOF Wrong flag !!
