Pada tanggal 31 Oktober 2022, PR di CrackMapExec dari Thomas Seigneuret (@Zblurx) digabungkan. PR ini memperbaiki otentikasi Kerberos dalam kerangka kerja CrackMapExec. Melihat itu, saya langsung ingin mencobanya dan bermain-main dengannya. Saat melakukannya, saya menemukan perilaku aneh dengan grup Pengguna Terlindungi. Dalam posting blog ini saya akan menjelaskan apa itu grup Pengguna Terlindungi, mengapa itu adalah fitur keamanan yang bagus dan mengapa itu tidak lengkap untuk pengguna Administrator (RID500).

berikut adalah scenario yang sering terjadi di internal assessments.kami mengkompromikan satu server, membuang database SAM dan memori LSASS-nya untuk mengambil kredensial teks-jelas atau hash NT. Kami juga dapat membuang tiket Kerberos dan umumnya materi lain yang dapat kami gunakan untuk terhubung ke tempat lain:

Baik itu di database SAM atau di memori proses LSASS, Anda mungkin akan menemukan hash NT:

Di Windows, memiliki hash NT sama dengan memiliki kata sandi teks-jelas. Jika kita melihat protokol autentikasi NTLM, kita dapat melihat bahwa tantangan tersebut dikodekan menggunakan hash NT pengguna:

Karena kami memliki hash NT, kami dapat menyalin tantangan tanpa mengetahui kata sandi teks-jelas yang sesuai.
