Akun Comcast Xfinity Diretas Dalam Serangan Bypass 2FA yang Meluas

December 23, 2022 by Coffee Bean

Pelanggan Comcast Xfinity melaporkan akun mereka diretas dalam serangan luas yang melewati autentikasi dua faktor. Akun yang dikompromikan ini kemudian digunakan untuk mengatur ulang kata sandi untuk layanan lain, seperti pertukaran crypto Coinbase dan Gemini.

many Xfinity email users began receiving notifications that their account information had been changed. However, when attempting to access the accounts, they could not log in as the passwords had been changed.

Mirip dengan Gmail, Xfinity memungkinkan pelanggan untuk mengonfigurasi alamat email sekunder yang akan digunakan untuk pemberitahuan akun dan pengaturan ulang kata sandi jika mereka kehilangan akses ke akun Xfinity mereka.

BleepingComputer first learned of these account hacks after numerous Xfinity customers reached out to us to share their experiences. In addition, other customers shared similar reports on Reddit [1, 2], Twitter [1, 2, 3], and Xfinity’s own support forum.

Bypass 2FA diduga beredar secara pribadi
Seorang peneliti telah memberi tahu BleepingComputer bahwa serangan dilakukan melalui serangan isian kredensial untuk menentukan kredensial masuk untuk serangan Xfinity.

Begitu mereka mendapatkan akses ke akun dan diminta untuk memasukkan kode 2FA mereka, penyerang diduga menggunakan bypass OTP yang diedarkan secara pribadi untuk situs Xfinity yang memungkinkan mereka memalsukan permintaan verifikasi 2FA yang berhasil.

Email utama Xfinity juga akan menerima pemberitahuan bahwa informasi mereka telah diubah, tetapi karena kata sandi juga telah diubah, tidak akan dapat mengaksesnya.

Begitu mereka mendapatkan akses penuh ke akun email Xfinity, pelaku ancaman mencoba untuk melanggar layanan online lebih lanjut yang digunakan oleh pelanggan, memverifikasi permintaan pengaturan ulang kata sandi ke akun email yang sekarang disusupi.

Sementara BleepingComputer tidak dapat memverifikasi keabsahan bypass OTP ini secara independen dan apakah itu telah digunakan dalam peretasan yang dilaporkan, ini akan menjelaskan bagaimana pelaku ancaman dapat memperoleh akses ke akun dengan 2FA diaktifkan.
