Cobalt Strike是一款常用于后渗透的神器,这个工具以团队作为主体,共享信息,拥有多种协议上线方式,集成了端口转发,端口扫描,socket代理,提权,钓鱼等。除去自身功能外,Cobalt Strike还利用了Metasploit和Mimikatz等其他知名工具的功能。

-
Cobalt Strike可以使用 AggressorScripts脚本来加强自身,能够扩展菜单栏,Beacon命令行,提权脚本等
-
Cobalt Strike通信配置文件是 Malleable C2 你可以修改 CS的通讯特征,Beacon payload的一些行为
-
Cobalt Strike可以引用其他的通讯框架ExternalC2,ExternalC2是由Cobalt Strike提出的一套规范/框架,它允许黑客根据需要对框架提供的默认HTTP(S)/DNS/SMB C2 通信通道进行扩展。
总的来说 CS的自定义功能很强大,使用起来很灵活后期,会讲到相关的使用。
Cobalt Strike 需要团队服务器才能使用,也就是teamserver。 需要文件 teamserver 与 cobaltstrike.jar 可以选择把他放在公网上面
执行 sudo ./teamserver
./teamserver <host> <password> [/path/to/c2.profile] [YYYY-MM-DD]
<host> is the (default) IP address of this Cobalt Strike team server
<password> is the shared password to connect to this server
[/path/to/c2.profile] is your Malleable C2 profile
[YYYY-MM-DD] is a kill date for Beacon payloads run from this server
在没有使用 自己的Malleable C2 profile情况下只填host 与 password即可
启动CS ./cobaltstrike.jar
其中user就是你想要输入的名字,password 为启动teamserver的密码
进入主文件
New Connection //新的链接
Preferences 偏好设置
Visualization 窗口视图模式
VPN interfaces VPN接入
Listeners 监听器
Sript Manager 脚本管理
Close 退出
其中 Preferences 可以删除 登陆记录的账户密码 与team server SSL ,其他的就是软件的一些颜色等。
