| 描述： | In today's backyard adventure, we found a cable running through the bushes! We followed it as far as we could, but after half a mile it seemed to go underground. Removing the wire's protective casing revealed 5 labeled wires, 3 of which were colored and all of which had a single letter. Thanks to generous Nick Jr. funding we bought an 8-channel oscilloscope and probed all the wires. Can you help us figure out what was sent? 得到的flag使用NSSCTF{}格式提交。 |
