Serangan siber InterContinental Hotels Group mengganggu sistem pemesanan

September 7, 2022 by Eevee

Perusahaan perhotelan terkemuka InterContinental Hotels Group PLC (juga dikenal sebagai IHG Hotels & Resorts) mengatakan sistem teknologi informasi (TI) telah terganggu sejak kemarin setelah jaringannya dibobol.

IHG adalah perusahaan multinasional Inggris yang saat ini mengoperasikan 6.028 hotel di lebih dari 100 negara dan memiliki lebih dari 1.800 dalam jalur pengembangan.

Meskipun perusahaan tidak mengungkapkan rincian apa pun mengenai sifat serangan itu, perusahaan itu menyebutkan dalam pengungkapannya bahwa mereka sedang berupaya memulihkan sistem yang terkena dampak.

Ini mengisyaratkan kemungkinan serangan ransomware di mana pelaku ancaman telah menyebarkan muatan ransomware dan sistem terenkripsi di jaringan IHG.

Dalam sebagian besar insiden ransomware, penyerang juga akan mencuri informasi sensitif dari jaringan target mereka sebelum enkripsi.

Ini kemudian digunakan dalam skema pemerasan ganda di mana para korban ditekan untuk membayar uang tebusan di bawah ancaman kebocoran data yang dicuri.

Bulan lalu, geng ransomware Lockbit mengklaim serangan terhadap Holiday Inn Istanbul Kadıköy, salah satu hotel yang dioperasikan oleh IHG.

Dari pengujian BleepingComputer, API grup hotel juga turun dan menunjukkan kesalahan HTTP 502 dan 503.

Pelanggan juga tidak dapat masuk saat ini, dengan aplikasi IHG menampilkan “Ada yang tidak beres. Kredensial yang Anda masukkan tidak valid. Harap setel ulang kata sandi Anda atau hubungi Layanan Pelanggan.” kesalahan.

Perusahaan intelijen kejahatan dunia maya Hudson Rock mengatakan bahwa IHG memiliki setidaknya 15 karyawan yang disusupi dan lebih dari 4.000 pengguna yang disusupi, menurut data yang ditautkan ke domain ihg[.]com.

Raksasa jaringan hotel itu juga menjadi sasaran pelanggaran keamanan selama tiga bulan pada tahun 2017—antara 29 September hingga 29 Desember—ketika lebih dari 1.200 hotel waralaba InterContinental di Amerika Serikat terkena dampaknya.
