What is a ransomware attack?
A ransomware attack is commonly known as a trojan horse situation in that your device is encrypted without your knowledge. A ransom is then demanded in exchange for the return of your data.
To put it simply, imagine someone breaking into your home, changing the locks and charging you a ransom to re-enter your home.
What are phishing emails?
Phishing emails are defined as disguised emails. The goal of these attacks is to trick you into believing that the message is something that you want or need to read. It could be a request from your bank or a note from someone in the office. But, once you click on this email, the attacker can encrypt all the data within your device.
How to prevent a ransomware attack?
- Make sure your data is always backed up. If you’ve got an external backup, you should still have access to your data if the worst-case scenario happens.
- Always avoid giving out your personal information. If you receive a call, text or email from an untrusted source requesting personal information, it is generally cybercriminals.
3. Keep your operating systems up to date. Regularly updating programmes and operating systems will help protect you from malware attacks. However, when performing these updates, make sure you benefit from the latest security protections making it more difficult for cybercriminals to exploit the vulnerabilities in your programmes.
4. When working remotely, we often connect to public Wi-Fi networks. However, using these networks will make your device more vulnerable to an attack that could affect your whole IT system. So, avoid using public Wi-Fi networks, especially for sensitive situations where your personal information is on display. You can create a Virtual Private Network (VPN) to ensure you are safe online when working remotely.
5. Never download software or files from unknown sites. This sounds obvious but sometimes these unverified sites look so authentic it is easy to be confused. So, to avoid confusion and risk of your data make sure to check that the browser address bar of the page uses “https” instead of “http”. There will also be a shield or lock symbol in the address bar which indicates the website is secure and safe for you to use.
What to do if you are hacked by ransomware!
- One of the most common assumptions is to pay the ransom. However, this isn’t always a sure thing. Cybercriminals cannot be trusted. Once the ransom is paid, it’s not guaranteed that you will receive your data back. Plus you’ll never know if the attackers made copies of your data for future use.
- Disconnect any devices connected to your network. This will help prevent movement from ransomware and keep other devices on your network safe.
