Extreme — Challenge 1

AES is a modern cipher where the ciphertext usually is displayed in Base64 format and is usually not used in decoding puzzles, but a lot of the time people see base64 and assume that they can decode it with a simple base64 decoder. In AES keys are usually displayed in Hex format. Can you figure out what mode of AES this is? CBC? ECB? GCM? Good luck decoding it!
