Cipher Chase
The Hacker’s Warning (Caesar Cipher)
Operation Cipher Chase:
A classified government document containing national security protocols has been stolen by a notorious hacking group known as "Cipher Syndicate." They have hidden key intelligence across different layers of encryption to prevent recovery.
As a cybersecurity investigator, your mission is to break their encryption methods, track their movements, and recover the stolen data before they auction it on the dark web!
Scenario:
The Cipher Syndicate left behind a taunting message at the breach site. It seems shifted and unreadable, but this might be the first clue to uncovering their next move.

Intercepted Transmission (XOR Cipher)
Scenario:
You intercept a radio transmission from one of the hackers. However, the data is XOR-encoded using a simple key to obscure its contents.(0x41)
Ciphertext (Hex):
2A 39 3B 0F 38 3B 0E 2A 30 39 3B 0E
Dark Web Coordinates (Base64 Encoding)
Scenario:
The decrypted signal contained a mysterious string, likely a link to an underground marketplace where the stolen documents will be auctioned. But it's in Base64 format.

Compromised Insider (Substitution Cipher)
Scenario:
A captured hacker confesses that an insider agent helped steal the classified document. A note found in their safe house contains more details, but the message seems shifted oddly.

Final Decryption: The Stolen File (Hex Encoding)
Scenario:
The final step—deciphering the stolen document itself! The hackers stored it in hexadecimal format, making it unreadable without conversion.
