AT&T memberi tahu 9 juta pelanggan tentang pelanggaran data setelah peretasan vendor

March 11, 2023 by Søren

AT&T memberi tahu sekitar 9 juta pelanggan bahwa beberapa informasi mereka terungkap setelah vendor pemasaran diretas pada bulan Januari.

“Informasi Jaringan Kepemilikan Pelanggan dari beberapa akun nirkabel terungkap, seperti jumlah saluran pada akun atau paket tarif nirkabel,” AT&T memberi tahu BleepingComputer.

“Informasi tersebut tidak mengandung informasi kartu kredit, Nomor Jaminan Sosial, kata sandi akun, atau informasi pribadi sensitif lainnya. Kami memberi tahu pelanggan yang terpengaruh.”

Sementara pemberitahuan pelanggaran data tidak membagikan jumlah pelanggan yang terkena dampak, AT&T memberi tahu BleepingComputer bahwa “sekitar 9 juta akun nirkabel telah mengakses Informasi Jaringan Kepemilikan Pelanggan mereka.”

Data CPNI yang terekspos mencakup nama depan pelanggan, nomor akun nirkabel, nomor telepon nirkabel, dan alamat email.

“Sebagian kecil pelanggan yang terkena dampak juga memiliki paparan nama paket tarif, jumlah yang lewat jatuh tempo, jumlah pembayaran bulanan, berbagai biaya bulanan dan/atau menit yang digunakan. Informasi tersebut sudah berumur beberapa tahun,” kata AT&T.

Perusahaan menambahkan bahwa sistemnya tidak dikompromikan dalam insiden keamanan vendor dan bahwa data yang terbuka sebagian besar terkait dengan kelayakan peningkatan perangkat.

“​Kami telah memberi tahu penegak hukum federal tentang akses tidak sah CPNI Anda seperti yang dipersyaratkan oleh Komisi Komunikasi Federal,” kata AT&T dalam surat pemberitahuan pelanggaran CPNI, pertama kali ditemukan oleh DataBreaches.net dan dikirim dari att@message.att-mail. com.

“Laporan kami kepada penegak hukum tidak berisi informasi spesifik tentang akun Anda, hanya akses tidak sah yang terjadi.”

Pelanggan disarankan untuk menonaktifkan pembagian data CPNI di akun mereka dengan membuat Permintaan Pembatasan CPNI untuk mengurangi risiko paparan di masa mendatang jika AT&T menggunakannya untuk tujuan pemasaran vendor pihak ketiga.
