Ini Langkah Efektif Cegah Ransomware Wannacry di PC Dunia internet dihebohkan dengan serangan ransomware bernama Wannacry. Serangan mematikan ini disinyalir melumpuhkan beberapa jaringan milik instansi di lebih dari 99 negara.
Berdasarkan data Avast, sebuah perusahaan penyedia jasa keamanan komputer, sekitar 75.000 serangan ransomware Wannacry terjadi pada Sabtu (13/5/2017) dan terjadi di 99 negara di dunia.
Menanggapi hal ini, Staff Divisi Aplikasi Database dan Data Center Keamanan Jaringan Kominfo Adi Jaelani, mengatakan bahwa Wannacry hanya menyerang komputer yang menggunakan sistem operasi Windows, khusunya versi Windows 08 ke bawah.
"Menyerang komputer berbasis Windows 2008 ke bawah. Jadi komputer berbasis Mac atau Linux tidak terdampak," ujarnya di Jakarta, Minggu (14/5/2017).
Tak lupa, ia juga memaparkan beberapa cara efektif untuk mencegah penyebaran Wannacry di komputer Anda. Berikut merupakan langkah-langkah yang Adi paparkan.
1. Sebelum hidupkan komputer atau server, matikan WiFi dan cabut koneksi LAN.
2. Setelahnya, segera pindahkan data ke sistem operasi non Windows (Linux, Mac). Bisa juga, pindahkan data ke media storage terpisah.
3. Lakukan update security pada Windows dengan instal Patch MS17-010 yang dirilis Microsoft.
4. Lakukan pembaruan antivirus. Pastikan, di antivirus yang Anda gunakan terdapat fitur anti ransomware.
5. Matikan fungsi server message block (SMB) dan jangan menyalakan fungsi macros.
6. Melakukan blokir ports: 139/445 dan 3389.
"Dengan melakukan langkah di atas, komputer Anda akan aman dari seragan Wannacry," tutupnya.
