LockBit2.0 是一種現可利用AD群組原則的勒索軟體,能自動加密Windows 網域下所有電腦,駭客不必寫程式進行勒贖軟體部署,只要取得 Windows Server 網域控制器的存取權,就能自動進行傳播,並在網域控制器上建立新的群組原則,將其推送到 Windows 網域中的所有電腦。這些原則包含禁用安全措施,例如 Microsoft Defender 和警報,並阻止操作系統向 Microsoft 提交樣本以避免檢測,以實現持久性。

This is a big deal. Typically Emotet dropped TrickBot or QakBot, which in turn dropped CobaltStrike. You'd usually have about a month between first infection and ransomware. With Emotet dropping CS directly, there's likely to be a much much shorter delay. https://t.co/QHGU4oq9Zi
