  • What is Ransomware and how to secure the data from it?

    There was Waanacry ransomware attack recently. I wanted to know what is a ransomware attack and how to secure the data from it?

    Wannacry affected those who were running unpatched OS or unsupported OS. So, it's better to use patched OS.

      Ransomware is an attack wherein the user's access to data is blocked and demands payments to restore data. One of the best solutions to stay protected from ransomware is to keep your operating system and other software fully updated and patched. Also, you need to run robust and self-updating antivirus.

        Ransomware is a type of malicious software from cryptovirology that threatens to publish the victim's data or perpetually block access to it unless a ransom is paid. While some simple ransomware may lock the system in a way which is not difficult for a knowledgeable person to reverse, more advanced malware uses a technique called cryptoviral extortion, in which it encrypts the victim's files, making them inaccessible, and demands a ransom payment to decrypt them. In a properly implemented cryptoviral extortion attack, recovering the files without the decryption key is an intractable problem and difficult to trace digital currencies such as Ukash and Bitcoin are used for the ransoms, making tracing and prosecuting the perpetrators difficult.

          Ransomware is a kind of cyber attack that involves hackers taking control of a computer or mobile device and demanding payment. The attackers download malicious software onto a device and then use it to encrypt the victim's information. They threaten to block access to the files until a ransom is paid.

          As prevention is the best cure, one of the best ways to secure your data from it is to Back up your files. The greatest damage people suffer from a ransomware attack is the loss of files, including pictures and documents. So, it is recommended that you back up all of the information and files on your devices in a completely separate system. A good place to do this is on an external hard drive that isn't connected to the internet. This means that if you suffer an attack you won't lose any information to the hackers.

            Ransomware, also called Business Email Compromise, is a type of malicious software that infects a computer and restricts users' access to it until a ransom is paid to unlock.
