Security Flaw Windows Kritis Dapat Menyaingi WannaCry

December 22, 2022 by Coffee Bean

Kerentanan yang lebih serius daripada EternalBlue telah ada di Windows selama beberapa waktu, sebelum akhirnya ditemukan dan ditambal, ungkap para ahli.

Beritanya tidak ada orang tahu persis betapa berbahayanya itu. Pada kenyataannya, ini memungkinkan pelaku ancaman untuk menjalankan kode berbahaya tanpa memerlukan otentikasi. Lebih jauh lagi, ini dapat menyebar, memungkinkan pelaku ancaman untuk memicu reaksi berantai dari eksploitasi yang menggandakan diri pada titik akhir rentan lainnya. Dengan kata lain, malware yang menyalahgunakan cacat tersebut dapat menyebar ke seluruh perangkat seperti api.
Bagi mereka yang memiliki memori lebih pendek, EternalBlue adalah zero-day buatan NSA untuk Windows yang melahirkan WannaCry, mungkin ancaman ransomware global paling dahsyat yang pernah muncul.

Ketika Microsoft pertama kali menambalnya tiga bulan lalu, diyakini bahwa cacat tersebut hanya memungkinkan pelaku ancaman untuk mengambil beberapa informasi sensitif dari perangkat, dan dengan demikian, memberi label sebagai “penting”. Sekarang, perusahaan mengubah peringkat tersebut, melabelinya sebagai “kritis”, dengan skor keparahan 8,1.

Tidak seperti EternalBlue, yang merupakan zero-day dan meninggalkan pakar keamanan dan pembuat perangkat lunak yang berebut untuk membuat perbaikan, tambalan untuk kelemahan ini telah tersedia selama tiga bulan sekarang, jadi efeknya seharusnya agak terbatas.
