Google menerapkan mitigasi Chrome terhadap serangan Slipstreaming NAT baru

January 30, 2021 by Winnie the Pooh

Google telah memblokir delapan port tambahan di dalam browser web Chrome untuk mencegah variasi baru dari serangan bernama NAT Slipstreaming, para insinyur perusahaan mengumumkan hari ini.

Serangan Slipstreaming NAT asli pertama kali diungkapkan pada 31 Oktober 2020 oleh Samy Kamkar, seorang peneliti keamanan terkenal.

Serangan itu bekerja dengan memikat pengguna di situs web jahat di mana kode JavaScript akan membuat sambungan ke perangkat korban secara langsung, melewati pertahanan yang disediakan oleh firewall dan tabel terjemahan alamat jaringan (NAT).

Penyerang dapat menyalahgunakan koneksi ini ke sistem pengguna untuk meluncurkan serangan pada perangkat yang terletak di jaringan internal korban.

Versi awal serangan NAT Slipstreaming menyalahgunakan protokol Session Initiation Protocol (SIP) untuk membuat sambungan lubang jarum ini ke perangkat di jaringan internal melalui port 5060 dan 5061.

Dua minggu setelah serangan tersebut diketahui publik, Google menanggapi penemuan Kamkar dengan memblokir dua porta di Chrome 87 ini untuk mencegah penyerang menyalahgunakan teknik ini, yang oleh pembuat browser dianggap sebagai ancaman yang parah dan mudah disalahgunakan.

Apple dan Mozilla juga mengirimkan blok serupa di dalam Safari dan Firefox beberapa minggu kemudian.
