【摘要】:正一、引言2016年10月21日,美國DNS服務(wù)提供商Dyn遭受大規(guī)模攻擊,導(dǎo)致諸多網(wǎng)站停止服務(wù)。據(jù)統(tǒng)計,這次攻擊使得美國幾乎半個互聯(lián)網(wǎng)癱瘓。而且,這斷斷續(xù)續(xù)長達6個小時的攻擊,毫不夸張的說,此次損失為天文數(shù)字。(圖1)此次事件的元兇是惡意軟件"Mirai"源代碼,黑客使用Mirai與物聯(lián)網(wǎng)相結(jié)合,通過互聯(lián)網(wǎng)搜索物聯(lián)網(wǎng)設(shè)備,當掃描到物聯(lián)網(wǎng)設(shè)備(包括網(wǎng)絡(luò)攝像頭,智能開關(guān)等)后就嘗試使用默認密碼登陸,(一般是admin/admin,admin/123456之類的弱密碼,Mirai病毒自帶60個通用密碼)。一旦登陸成功,這臺

According to statistics, the attack nearly half of the United States Internet paralysis. Moreover, this intermittent 6-hour attack, no exaggeration, the loss is astronomical. (figure 1) the main culprit of the incident was the malware "Mirai" source code, which hackers used to combine Mirai with the Internet of things to search the Internet of things devices over the Internet of things, when scanned to the Internet of things devices (including webcams).
