20 May 2025 - Ransomware is one of the most disruptive cybersecurity threats facing small and medium businesses (SMBs). With attacks increasing in sophistication and frequency, protecting your business has never been more critical. This blog will help you understand what ransomware is, how it works, and what steps you can take to prevent and recover from an attack using modern malware protection solutions.
What is ransomware, and how does it work?
Ransomware is a malicious software, also known as malware, designed to block access to your files or systems by encrypting them. Encryption is like locking your data in a secure digital safe. When a file is encrypted, it’s scrambled into a code that only someone with the right “key” can unlock and read.
Cybercriminals use encryption in ransomware attacks to make your files unusable. Attackers then demand a ransom, typically in cryptocurrency, to restore access. These attacks often begin with a phishing email or an exploited vulnerability in your network, making every employee and device a potential entry point. For SMBs, a successful ransomware attack can mean costly downtime, lost data, and a damaged reputation.
What are the best practices to prevent ransomware attacks?
Preventing ransomware starts with proactive planning and layered malware protection. Here are some key steps:
- Regular Backups: Frequently back up critical data and store backups securely offline.
- Security Awareness Training: Teach employees to recognise phishing attempts and suspicious activity.
- Patch and Update Systems: Always apply the latest security updates to software and operating systems.
- Implement Endpoint Security: Use reputable security software to detect and block threats before they cause harm.
Steps to recover from a ransomware attack
If your business is targeted, taking swift action is crucial. These are the key steps to take:
- Disconnect Affected Devices: Limit the spread by isolating infected systems.
- Notify IT or Your Security Provider: Engage professionals to assess and contain the threat.
- Identify the Ransomware Strain: This can guide your recovery and response.
- Restore from Backups: Avoid paying the ransom by recovering clean data.
- Report the Incident: Alert relevant authorities and consider regulatory reporting.
