Can you find the flag? shark1.pcapng
Wireshark打开，找到一个响应中有Gur synt vf cvpbPGS{c33xno00_1_f33_h_qrnqorrs}\n，CybercChef中ROT13后拿到flag。
Cookies
Who doesn’t love cookies? Try to figure out the best one.
首先输入snickerdoodle，在开发人员工具里面看见附带一个Cookie: name=-1向/check发送了GET请求。
打开Fiddler，修改name，试到name=18时出现flag。
speeds and feeds
There is something on my shop network running at
nc mercury.picoctf.net 20301, but I can’t tell what it is. Can you?
搜索命令的第一行输出，可以搜出这是G Code。
然后搜G Code Online，能搜到这个模拟器：g-code simulator (nraynaud.github.io)
把整个输出都放进去模拟一下，就能看见flag了。
