Operation Stop Hack: Hidden Messages
Introduction
The solutions develop into a series of communication. Obtain and submit this project worksheet [DOCX] for credit score.
Record the solutions to all 5 ciphers, numbered 1–5.
Every reply is value 5 factors.
The FBI lately discovered some hidden recordsdata and messages on the laborious drive of the hacker from Operation Stop Hack. They’re enlisting your Help to find out the content material of those hidden messages. They need you to have the next Intel to Help together with your investigation:
INTEL
It seems as if the criminals have been utilizing cipher strategies to speak with their different members about targets and operations. We discovered a message that seem like encoded utilizing numerous quantity bases, substitution and ciphers.
We expect the next internet instruments will Help in your investigation:
Speedy Tables.
Rumkin’s Cipher Instruments.
Quantity bases; embrace base2 (binary), base10 (decimal), and base64.
Binary is represented by two numbers ones (1) and 0 (zero), therefore the base2, which implies that base 10 can be represented by 10 numbers, zero–9 (all the time begin with zero).
We have been ready to determine the primary message, which was encoded utilizing binary:
01001101 01100101 01100101 01110100 01101001 01101110 01100111 00100000 01110011 01100101 01110100 00100000 01100110 01101111 01110010 00100000 00110001 01110000 01101101 00100000 01100001 01110100 00100000 01110100 01101000 01100101 00100000 01001000 01101111 01110100 01000100 01101111 01100111 00100000 01010011 01101000 01100001 01100011 01101011
We decided that the primary message learn: Assembly set for 1pm on the HotDog Shack.
We used the Speedy Tables converter to determine the which means of this code. The binary was copied into the textbox that reads binary and the textual content reply is proven within the field labeled ASCII.
We’ve got tried to judge every message to find out the kind of cipher; now we ask that you just end the duty and crack the codes. Please return them to us shortly in case they may help seize different members.
This message seems to be encoded utilizing hexadecimal:
Ox 57 65 20 6E 65 65 64 20 74 6F 20 6D 65 65 74 2C 20 74 68 65 20 70 6F 6C 69 63 65 20 61 72 65 20 62 65 63 6F 6D 69 6E 67 20 73 75 73 70 69 63 69 6F 75 73
The following message seems to be base64:
U3RvcCB3b3JyeWluZywgdGhlIGpvYiBpcyBhbG1vc3QgZG9uZSBhbmQgeW91IHdpbGwgZ2V0IGEgbGFyZ2UgcGF5b3V0
The following missive seems to be encoded utilizing ROT13, so we advise utilizing the Rumkin Instruments:
Jung’f gur arkg wbo?
This e-mail was discovered and it seems to be Atbash:
Dv ziv tlrmt gl szxp gsv hsrkbziw hl dv xzm ivwrivxg z hsrknvmg lu wrznlmwh
The FBI are stumped: a double cipher was used to encode a message. It appears to be like like hexadecimal, however the ASCII textual content doesn’t appear like English. In addition they discovered the passphrase: secret. The message seems to be a kind of polyalphabetic substitution.
Decide what cipher is taken into account a polyalphabetic substitution cipher:
Ox 4C 6C 67 20 72 78 6D 73 67 6D 20 6E 6D 65 64 20 78 63 62 69 20 69 64 65 65 76 20 73 67 20 58 76 6B 75 65 72 20 45 65 61 20 39 6B 6C 20 78 70 65 65 6B 70 72 20 73 78 20 31 30 63 64 2E 20 43 68 6D 20 61 6B 63 70 20 6D 73 6F 67 20 6B 6C 78 61 76 20 67 64 65 62 64 20 77 61 6A 78 78 65 20 68 71 6E 72 2C 20 70 7A 6D 6E 76 20 4D 20 62 66 6E 67 74 78 20 6D 7A 69 20 75 70 77 6D 77 71 20 79 7A 78 61 20 73 20 67 71 75 69 20 6D 7A 65 76 20 6E 6D 65 64 20 76 67 69 73 6E 6C 69 20 76 79 69 20 6C 7A 6D 72 64 69 67 6C 2E
