WindowsのKerberos認証で使われてきた1987年生まれの暗号RC4が、来月の更新でついに既定から外れます。

対応を怠った環境では認証不能に陥る可能性があり、FSLogixを使った仮想デスクトップ環境にも影響が及びます。

2024年のAscension事件では約560万人の患者記録が流出しており、RC4の脆弱性が攻撃の足がかりとなりました。

30年分のセキュリティ負債の清算が、いよいよ始まります

Active Directory Penetration Testing with BloodyAD This walkthrough demonstrates a complete Active Directory attack chain against the ignite.local lab using BloodyAD and Impacket, covering enumeration, privilege escalation, Kerberos attacks, credential dumping, RBCD, and persistence techniques. It highlights common misconfigurations—cleartext LDAP attributes, permissive ACLs, default machine account quotas, and disabled Kerberos pre-authentication—and provides detection and defensive recommendations. #BloodyAD #DCSync

Microsoft eliminará la función NTLM este año e insta a los administradores de TI a prepararse Con la finalidad de aumentar la seguridad en Windows 11 y Server 2025, Microsoft ha anunciado que este año eliminarán la función NTLM y por ello, están instando a los administradores de TI a prepararse para este cambio. Esto obviamente quiere decir que los administradores TI deben ir preparando sus respectivos entornos para la eventual desactivación de NTLM.

Microsoft anuncia que antes de finalizar este año, eliminarán el protocolo de autenticación NTLM ¿Cómo deben prepararse los administradores de TI ante este escenario?
