發(fā)作時(shí)的狀態(tài)：
幾秒鐘內(nèi)發(fā)送幾十萬(wàn)的udp  dns請(qǐng)求包，目標(biāo)地址8.8.8.8（好像是谷歌的dns），還會(huì)定時(shí)的往外發(fā)送少量的探測(cè)包，防火墻瞬間就癱瘓了。

查殺過(guò)程：照著上面的內(nèi)容把文件都刪除了，數(shù)據(jù)包暫時(shí)沒(méi)發(fā)現(xiàn)異常，但會(huì)產(chǎn)生一個(gè).ssh14（后面一大串?dāng)?shù)字）,/tmp目錄下會(huì)生成跟改進(jìn)程名一樣的文件，并且這個(gè)進(jìn)程還會(huì)不斷的生成僵尸進(jìn)程，并且這個(gè)進(jìn)程怎么殺都?xì)⒉坏�，求高人幫�?br />
