What is Ransomware and how does it affect your business?

Businesses are the primary target of ransomware attacks, and until the crisis in the NHS most people had never heard of Ransomware. So what is Ransomware and how can you prepare and protect your business?

What is Ransomware?

Ransomware is a piece of malicious software that is inserted into a host computer, via an executable file. This is done either through automated bot software written specifically to inject ransomware into a computer system or by sending a malicious file to an unsuspecting user.

Ransomware, once executed, blocks access to files by encrypting them. This can then spread to all files on a network, other machines and local backups. In order to regain access to the files, a sum of money has to be paid to the attacker, a.k.a. the “Ransom”.

Scary stuff! However, all is not lost as there are measures that can be taken to protect sensitive information.

Regular Backups

One thing that can be done against Ransomware is making backups of the data. This can be done by utilising offsite backup. The offsite copy is then protected from the Ransomware attack and this backup can then be used to restore your encrypted data.

Regular backups also protect the business against the corruption of accidental deletion.

Disaster Recovery

Unlike data backup, a good disaster recovery plan helps a business recover from a catastrophic failure.

How would your business recover from a server crash or building fire? With disaster recovery, multiple snapshots of your whole servers are taken daily and uploaded to the cloud. In the event of failure, these snapshots can be “spun up” in the cloud and users logged in from remote locations. This will result in minimal downtime for a business, while replacement on-site hardware is delivered.

You can then restore this virtual image onto the new hardware.
