Ransomware: Preventing an attack on your business software systems

How would your business cope with Dynamics NAV offline for up to a week - unable to take or ship orders, or update your customers with progress reports?

These are the problems faced by some companies who have been targeted by hackers through the malware known as ‘ransomware’.

What is Ransomware?

Ransomware is a tool hackers used to gain access to the data on PCs and servers within your organisation.

Ransomware can be spread simply by clicking on an internet link or opening an email attachment. Once it is in your system, hackers use unbreakable encryption on your data so you cannot access it or decrypt it yourself, then request a ransom for you to get it back.

Why Ransomware is a threat: The facts

  • You will often be given a time limit to pay the hackers, with the threat of the complete destruction of your data if you fail to keep to the deadline. Paying the ransom doesn’t guarantee that you will get your data back.
  • The money you send is most likely to be untraceable, as many hackers request payment in Bitcoins, which cannot be tracked by authorities.
  • If ransomware does infect one of your PCs, it can take up to a day to clean and restore to working order.
  • The time you would lose if this contagion spread and infected more PCs, as well as your Dynamics NAV and CRM deployment inside your organisation, could spell disaster for your business.
 
 

Knowledge is Power

We believe that knowledge is power. The more people inside your organisation who are aware that ransomware exists, the better.

With that in mind, we have created three short videos with our Technical Manager, Nathan Sanders, to help you understand what ransomware is, how to deal with the problem if you do become infected and most importantly, how to prevent it in the first place.

We recommend that you watch these, and share them within your teams.

Prevention is Better than Cure

There are several ways you can protect yourself against the threat of ransomware:

Back-ups

Ensure you keep back-ups of your data, and test them regularly. Encrypting your data will safeguard against your company data falling into the wrong hands.

Keep up to date

Update your devices regularly as new security features are released frequently to keep your data safe from malware.

Educate your organisation

Educating your staff is one of the best ways of ensuring ransomware is not let into your organisation. They need to know to question the validity of the emails they receive, even ones from inside your organisation. Look out for key phrases that other employees may use, and be aware of the style of the email that has been sent so they know if an email seems suspicious.

Secure your network with a firewall

Advanced firewalls are recommended to protect against attacks like these, as hackers have gotten wise to standard protection, and this will now no longer suffice to protect your data. Firewalls scan all the traffic coming in and out and look for anomalies and viruses to stop them at the source before they get anywhere near your PCs.

Protect your servers

Antivirus and security software is essential for any business as they block potential threats and can alert users if any suspicious activity occurs.

Email protection

A decent anti-spam tool will filter your emails for you to find the ones with embedded links or suspect attachments to secure your network.

 
 

How We Can Help If You Do Get Infected

Firstly, we work with you to clean off the ransomware from any infected machines and servers.

Once you have spoken to someone in our team and have had your machines cleaned, we perform a data restore process. Then, most crucially, we will investigate how the ransomware got into the system in the first place and put measures in place to ensure that it doesn’t happen again.
