Ransomware làm gì? Sưu tầm trên MS 00:00 15/05/0017
Có nhiều loại ransomware khác nhau. Tuy nhiên, tất cả chúng đều có điểm chung là sẽ ngăn bạn quá trình sử dụng máy tính bình thường, và tất cả chúng sẽ yêu cầu bạn phải làm một cái gì đó trước khi bạn có thể sử dụng lại máy tính của bạn.
Chúng có thể nhắm mục tiêu bất kỳ đến người dùng máy tính, cho dù đó là một máy tính ở nhà, máy trong một doanh nghiệp, hoặc máy chủ,....
Ngăn cản bạn truy cập vào máy tính.
Mật mã hóa tệp vì vậy, bạn không thể sử dụng chúng.
Ngăn chặn một số ứng dụng chạy (như trình duyệt).
Ransomware sẽ yêu cầu bạn phải trả tiền (một khoản "chuộc") để có được quyền truy cập vào PC hoặc tập tin của bạn.
Không có gì bảo đảm rằng trả tiền chuộc hoặc làm những gì ransomware yêu cầu bạn thì bạn sẽ được truy cập vào PC hoặc tập tin của bạn.
Làm thế nào để có được các tập tin của tôi trở lại?
OneDrive tạo ra một phiên bản của Microsoft Office các tập tin khi bạn lưu hoặc thay đổi các tập tin như một phần của các tính năng bảo mật.
Một số Ransomware cũng sẽ mã hoá hoặc xóa các phiên bản sao lưu của tập tin của bạn. Điều này có nghĩa rằng ngay cả khi bạn đã bật lịch sử tập tin, nếu bạn đã thiết lập vị trí sao lưu sẽ là một mạng hoặc ổ đĩa sao lưu cục bộ của bạn có thể cũng mã hoá. Bản sao lưu trên một ổ đĩa lưu động, hoặc một ổ đĩa không kết nối vào máy khi bạn đã bị nhiễm ransomware, vẫn có thể tốt.
