① 网络流量威胁-xmrig协议PCAP分析
1、xmrig木马
挖矿木马成为黑产团伙的主要获利方式之一，也成为了企业内部安全的主要威胁之一。门罗币很多僵尸网络也把挖矿作为主要的获利手段。本文分析挖矿连接的行为。
2、具体样本
样本具有连接xmrig矿池通信行为，xmrig协议通信；
3、PCAP分析
相关实验的 xmrig通信PCAP
DNS Standard query A xmr.pool.minergate.com
xmrig协议格式【1】
request：
{"id":x,"jsonrpc":"2.0","method":"login","params":{"login":"xxxxxx","pass":"x","agent":"xxxxx","algo":["xxx","xxx","xxx"]}}
{"id":x,"jsonrpc":"2.0","method":"submit","params":{"id":"xxxx","job_id":"xx","nonce":"xxxx","result":"xxxxxxx"}}
response：
{"params":{"blob":"xxxxxx","taget":"xxxx","job_id":"xxxxx"},"method":"xxx"}
本次抓包具体例子：
{"id":1,"jsonrpc":"2.0","method":"login","params":{"login":"xxx","pass":"x","agent":"Static XMRig/2.13.1 (Linux x86_64) libuv/1.24.1 gcc/6.4.0","algo":["cn","cn/r","cn/wow","cn/2","cn/1","cn/0","cn/half","cn/xtl","cn/msr","cn/xao","cn/rto","cn/gpu"]}}
