Monday: So today Rick told me huge secret. He had finished his flask and was on to commercial grade paint solvent. He spluttered something about a safe, and a password. Or maybe it was a safe password... Was a password that was safe? Or a password to a safe? Or a safe password to a safe?
Anyway. Here it is:
FLAG: {131333} - 20 Points
使用找到safe二进制文件的提示，我查找了 Rick 的旧乐队 - The Flesh Curtains。我还需要根据这些单词按特定顺序进行一些密码排列：
1个大写字符
然后，1个号码
最后，乐队的话之一——
Flesh或者Curtains
使用 Hashcat 进行排列maskprocessor：
# ?u = upper
# ?d = digit
mp64 ?u?dFlesh >> rick
mp64 ?u?dflesh >> rick
mp64 ?u?dCurtains >> rick
mp64 ?u?dcurtains >> rick现在使用我的单词表 – rick，我将尝试通过以下方式暴力破解 SSH hydra：
hydra -IVf -s 22222 -l RickSanchez -P rick ssh://target-ip-address而且，一段时间后我受到了打击：P7Curtains
最后更新于
这有帮助吗？
