Microsoft memperbaiki NTLM relay zero-day baru di semua versi Windows

May 11, 2022 by Winnie the Pooh

Microsoft telah memperbaiki kerentanan zero-day Windows LSA spoofing yang dieksploitasi secara aktif yang dapat dieksploitasi oleh penyerang dari jarak jauh untuk memaksa domain controller mengautentikasi mereka melalui protokol keamanan Windows NT LAN Manager (NTLM).

LSA (kependekan dari Local Security Authority) adalah subsistem Windows yang dilindungi yang memberlakukan kebijakan keamanan lokal dan memvalidasi pengguna untuk login lokal dan jarak jauh.

Kerentanan, dilacak sebagai CVE-2022-26925 dan dilaporkan oleh Raphael John dari Bertelsmann Printing Group, telah dieksploitasi di alam liar dan tampaknya menjadi vektor baru untuk serangan relay PetitPotam NTLM.

Ditemukan oleh peneliti keamanan GILLES Lionel pada Juli 2021, PetitPotam memiliki beberapa variasi yang coba diblokir oleh Microsoft. Namun, pada titik ini, mitigasi resmi dan pembaruan keamanan berikutnya tidak sepenuhnya memblokir semua vektor PetitPotam.

Operator ransomware LockFile telah menyalahgunakan metode serangan relay PetitPotam NTLM untuk membajak domain Windows dan menyebarkan muatan berbahaya.

Microsoft menyarankan admin Windows untuk memeriksa mitigasi PetitPotam dan langkah-langkah mitigasi terhadap NTLM Relay Attacks pada Active Directory Certificate Services (AD CS) untuk info selengkapnya tentang melindungi sistem mereka dari serangan CVE-2022-26925.
