5 Ways that you can protect against Ransomware.

What is ransomware?  Well, as the name suggests, it is a nasty piece of software that infects your network and computers with the simple task of encrypting your data and holding it at ransom. It heavily encrypts the data, and the attacker is the only one holding the key to decrypt your data. The only way to obtain the key is to pay the ransom fee requested, and even then, there is no guarantee that you will be able to decrypt your data.

As a Managed Service Provider, we at O’NERO IT Services know all too well how this can affect you, your business and your staff and that is why we use and provide ESET end-point security solutions to our customers.

Learn to spot a ‘Phish’: Phishing schemes use various ways to try and tick the recipient into clicking on a link.


Here are 5 things that you can do to protect against ransomware:

  • Keep your software programs and operating systems up to date: Yes, we know those pop-ups reminding you to upgrade can be annoying, but there is a valid reason behind it. These program updates typically include the latest security patches and updates required to ensure that your programs and or operating systems remain secure.
  • Use an Internet Security Suite: A full featured security suite like ESET smart security provides comprehensive protection and is more than just an antivirus application.
    • Anti-spam that filters our emails that might contain ransomware-spreading attachments or links to ransomware websites
    • Anti-phishing that prevents you from visiting suspicious sites masquerading as trustworthy
    • An exploit blocker that protects against security holes in software often used to spread infections and add another layer of protection by fortifying applications on users’ systems that are often exploited, such as web browsers, PDF readers, email clients or other MS Office components
    • Software firewall can block ransomware from connection to a command-and-control server before encrypting your files, providing an additional layer of defence
  • Learn to spot a ‘Phish’: Phishing schemes uses various ways to try and trick the recipient into clicking on a link. In most instances, it would seem like a legitimate email from a reputable company. If the email address seems different for example, instead of a .co.za it comes from a .com, rather let us have a look at it before you open any link or attachment.
  • Backup your data: This might not be a way to stop or deter ransomware, but too often we have seen that companies simply do not have adequate backups in place for their most vital data when they are hit with a ransomware attack. By ensuring that you have adequate data backups in place including a recovery procedure, you can simply remove the ransomware from your network and then restore the data backups.
  • Increase security settings through stricter GPO’s or Group Policy Objects: By limiting or grouping users together and limiting rights and access, you are adding an additional layer of security onto your network. A simple example would be to block all USB drives on company laptops or PCs. As users, we tend to charge our mobile devices directly from our laptops or PCs, and if left unchecked, can open the door for viruses and or ransomware to enter your network.

These are the 5 simple steps that you can take to deter and even prevent your business from suffering the consequences of ransomware.
