WASPADA VIRUS RANSOMEWARE

PCMan Banner Ransome-02

 

Maraknya informasi tentang serangan virus Ransomware WannaCry sangatlah mengancam keamanan data kita. Secara khusus, pada tanggal 12 Mei 2017, strain baru ransomware Ransom.CryptXXX (WannaCry) mulai menyebar luas mempengaruhi sejumlah besar organisasi, terutama di Eropa, dan informasi terakhir sudah merambah sampai ke Indonesia. Wcry menuntut uang tebusan sebesar $ 300 sampai $ 600 di Bitcoin yang harus dibayar pada tanggal 15 Mei, atau, jika tenggang waktu tidak terjawab, bisa meminta biaya yang lebih tinggi pada tanggal 19 Mei. Pesan yang tersisa di layar mengatakan bahwa file akan tetap dienkripsi. Belum jelas apakah ada kekurangan dalam skema enkripsi yang memungkinkan korban mengembalikan file tanpa membayar uang tebusan, dan jika uang tebusan dibayarkan pun tidak menjamin file kita yg terinfeksi dapat dibuka kembali.

Himbauan kami :
Pastikan Operating System anda sudah service pack terakhir. Jika anda belum menginstal Microsoft fix-MS17-010 – Anda harus melakukannya segera. Kemudian pastikan semua Antivirus Servers dan Clients sudah ter-up to date. Dan pastikan juga berhati-hati terhadap semua e-mail yang Diterima, terutama yang meminta penerima untuk membuka dokumen terlampir atau mengklik link ke Website tertentu.

Tidak lupa kami ingatkan pastikan Backup data harian anda berjalan dengan baik.
