xmrig挖矿样本分析 miner

首先推荐这个站点：https://tria.ge/220617-wchkbscghp

搜索：f924ddf42e5f1b8102e774b68fff7e40c217acee2f0fe1c44453766af97f419b 该样本比较鲜活，是2022-06-17才上传的。

然后注册账号，下载该挖矿样本。

然后本机上，可以运行，我看到的是：

wininit.exe和notepad.exe进程二者合起来占用我cpu 100%，单看的话，占用率50%。如果kill掉二者的话，notepad会再度重启，占用你几乎100%的CPU。（我vm是2核，这玩意从下图看还是很蛋疼啊！）
