Ransomware is one of the most talked-about cyber threats in business, and with good reason. It has shut down hospitals, disrupted local councils, and caused serious harm to thousands of small businesses across the UK.
Here is what it actually is, how it reaches businesses like yours, and what you can do about it.
What is ransomware?
Ransomware is a type of malicious software that encrypts your files so you cannot access them. Once your files are locked, the attacker demands a ransom payment in exchange for the key to unlock them.
The payment is usually demanded in cryptocurrency to make it hard to trace. There is no guarantee that paying will actually restore your files. Some businesses pay and receive nothing in return.
Beyond the ransom itself, there is the cost of downtime, data recovery, reputational damage, and in some cases regulatory penalties if personal data was involved in the breach.
How does ransomware reach small businesses?
The most common routes are:
- Phishing emails: a member of your team clicks a link or opens an attachment that triggers the infection
- Compromised passwords: attackers use leaked credentials to log into accounts and deploy ransomware manually
- Unpatched software: vulnerabilities in outdated software are exploited to gain access
- Malicious websites: visiting a compromised site can trigger a download without any obvious action from the user
Small businesses are targeted more often than people realise. Attackers are not always going after specific companies. They cast a wide net, and businesses with weaker defences are simply easier to compromise.
Real-world impact
A small business hit by ransomware might face days or weeks of disruption. Files that seemed safe turn out to have no recoverable backup. Customer data is potentially exposed. Staff cannot access the tools they need to work.
Even if the ransom is not paid, the cost of recovery, IT work, and lost productivity can run into thousands of pounds. For a small business operating on tight margins, that is a serious problem.
How do you protect against it?
There is no single tool that makes ransomware impossible. Protection comes from multiple layers working together:
- Multi-factor authentication: makes it much harder for attackers to access your accounts even if they have your password
- Patching and updates: keeping software up to date closes the vulnerabilities attackers exploit
- Email filtering: reduces the number of malicious emails that reach your team in the first place
- Staff training: people who can recognise a suspicious email are far less likely to click on one
- Endpoint protection: advanced antivirus software that detects and blocks suspicious behaviour on your devices
- Backups: a clean, tested backup means you can recover your data without paying a ransom
What if you are already infected?
If ransomware is detected, the priority is to isolate affected devices from the rest of your network immediately. Do not turn devices off, as this can sometimes complicate recovery. Contact your IT support provider straight away.
Do not pay the ransom without taking advice first. Payment does not guarantee recovery, and it funds further attacks on other businesses.
