14 serangan baru terdeteksi pada web browser

December 8, 2021 by Winnie the Pooh

Pakar keamanan TI telah mengidentifikasi 14 jenis serangan baru pada web browser yang dikenal sebagai kebocoran lintas situs, atau XS-Leaks.

Menggunakan XS-Leaks, situs web jahat dapat mengambil data pribadi dari pengunjung dengan berinteraksi dengan situs web lain di latar belakang.

Para peneliti dari Ruhr-Universität Bochum (RUB) dan Niederrhein University of Applied Sciences menguji seberapa baik 56 kombinasi browser dan sistem operasi terlindungi dari 34 XS-Leaks yang berbeda. Untuk tujuan ini, mereka mengembangkan situs web XSinator.com, yang memungkinkan mereka memindai browser secara otomatis untuk mencari kebocoran ini.

Peramban populer seperti Chrome dan Firefox, misalnya, rentan terhadap sejumlah besar XS-Leaks. “XS-Leaks seringkali merupakan bug browser yang harus diperbaiki oleh pabrikan,” kata Lukas Knittel, salah satu penulis makalah Bochum.

Para peneliti mempublikasikan temuan mereka secara online dan di “ACM Conference on Computer and Communications Security”, yang diadakan sebagai acara virtual pada pertengahan November 2021.

XS-Leaks melewati apa yang disebut sebagai same-origin policy, salah satu pertahanan utama browser terhadap berbagai jenis serangan. Tujuan dari same-origin policy adalah untuk mencegah informasi dicuri dari situs web tepercaya. Dalam kasus XS-Leaks, penyerang tetap dapat mengenali detail kecil individu dari sebuah situs web. Jika detail ini terkait dengan data pribadi, data tersebut dapat bocor.

Misalnya, email di kotak masuk email web dapat dibaca dari situs jahat, karena fungsi pencarian akan merespons dengan cara yang berbeda tergantung pada apakah ada hasil untuk istilah pencarian atau tidak.
