DDG

Botnet Baru Ini Bisa Membuktikan Hampir Tidak Mungkin Untuk Dihentikan

April 13, 2020 by Winnie the Pooh

Peneliti keamanan telah menemukan ancaman yang mereka khawatirkan bisa hampir tak terbendung. Botnet yang berkembang ini telah berhasil mengambil alih hampir 20.000 komputer.

Botnet ini dikenal sebagai DDG, dan telah bersembunyi setidaknya selama dua tahun.  DDG pertama kali ditemukan pada awal 2018 oleh para pakar keamanan jaringan di Netlab 360 yang berbasis di Cina.

Saat itu botnet yang baru lahir memiliki kendali atas lebih dari 4.000 komouter dan menggunakannya untuk menambang cryptocurrency Monero. Banyak yang telah berubah sejak saat itu. Inkarnasi DDG hari ini tidak hanya lima kali lebih besar. Namun juga jauh lebih canggih.

Salah satu fitur yang membedakan adalah sistem komando dan kontrolnya.  Sebagian besar botnet dirancang berdasarkan model klien/server. Mesin yang terinfeksi mendengarkan instruksi dari server dan kemudian melaksanakan pesanan mereka.

DDG memiliki Plan B bawaan, namun: jaringan peer-to-peer yang eksklusif.

Jika komputer yang telah diambil alih tidak dapat menghubungi server, mereka secara otomatis beralih ke saluran P2P untuk menjaga operasi berjalan – bertukar muatan dan instruksi seolah-olah tidak ada yang terjadi. Mereka bahkan menggunakan sistem proxy bawaan untuk mengaburkan kegiatan mereka.

Itu adalah langkah yang pengecut, dan yang menurut Netlab 360 juga membuat DDG “tampaknya tak terhentikan”. Para profesional keamanan sering mengganggu botnet dengan merebut kendali atas nama domain atau server penting dari operator kriminal. Itu tidak akan bekerja melawan DDG.
