Peneliti Keamanan Memperingatkan Kelas Baru Bug Apple

February 23, 2023 by Coffee Bean

Peneliti keamanan mengatakan mereka telah menemukan “kelas baru” kerentanan yang memungkinkan penyerang melewati perlindungan keamanan Apple di iOS dan macOS untuk mengakses data sensitif pengguna.

Pusat Penelitian Lanjutan Trellix menerbitkan detail minggu ini tentang kerentanan eskalasi hak istimewa — yang berarti mereka memungkinkan seseorang untuk mendapatkan tingkat akses yang lebih tinggi ke sistem — yang memengaruhi iPhone dan Mac. Trellix memperingatkan bahwa kelas bug, yang berkisar dari tingkat keparahan sedang hingga tinggi, dapat — jika dibiarkan tidak ditambal — memungkinkan aplikasi berbahaya untuk keluar dari “kotak pasir” pelindung mereka dan mengakses informasi sensitif di perangkat seseorang, termasuk pesan seseorang, data lokasi, riwayat panggilan dan foto.

Temuan Trellix mengikuti penelitian sebelumnya dari Google dan Citizen Lab, yang pada tahun 2021 menemukan eksploitasi zero-day baru yang dijuluki ForcedEntry yang disalahgunakan oleh pembuat spyware Israel NSO Group untuk meretas iPhone dari jarak jauh dan diam-diam atas perintah pelanggan pemerintahnya. Apple kemudian memperkuat perlindungan keamanan perangkatnya dengan menambahkan mitigasi penandatanganan kode baru, yang secara kriptografis memverifikasi bahwa perangkat lunak perangkat dipercaya dan belum dimodifikasi, untuk menghentikan eksploitasi eksploit.

Apple menambal kerentanan yang ditemukan Trellix di pembaruan perangkat lunak macOS 13.2 dan iOS 16.3, yang dirilis pada bulan Januari. Dokumen dukungan keamanan Apple juga diperbarui pada hari Selasa untuk mencerminkan rilis tambalan baru.

Will Strafach, seorang peneliti keamanan dan pendiri aplikasi firewall Guardian, menggambarkan kerentanan sebagai “cukup pintar”, tetapi memperingatkan bahwa hanya sedikit yang dapat dilakukan pengguna rata-rata terhadap ancaman ini, “selain tetap waspada dalam menginstal pembaruan keamanan.”

Dan peneliti keamanan iOS dan macOS Wojciech Reguła mengatakan kepada TechCrunch bahwa meskipun kerentanan bisa menjadi signifikan, jika tidak ada eksploitasi, diperlukan lebih banyak detail untuk menentukan seberapa besar permukaan serangan ini.
