Ransomware Readiness for Small Businesses

Ransomware encrypts your files and systems and demands payment for the key. Small and medium businesses are frequent victims because attackers expect weaker defences and a willingness to pay to restore operations quickly.

How attacks usually begin

Phishing emails with malicious attachments or links, stolen passwords for remote access, unpatched systems exposed to the internet and infected downloads are the most common entry points.

Prevention basics

• Keep operating systems, applications and network devices patched.
• Use protective DNS and email filtering to block known threats.
• Enable multi-factor authentication for email, remote access and admin accounts.
• Train staff to recognise phishing and suspicious payment requests.

Limit the damage

Network segmentation and least-privilege access mean that if one computer is infected, the attacker cannot easily reach everything else.

Immutable and offline backups

Attackers often try to delete or encrypt backups. Keep at least one copy that cannot be altered — offline, immutable cloud storage or write-once media.

Have a response plan

Know who to call, how to isolate infected systems, how to communicate with customers and staff, and how to restore from backups. Keep the plan accessible offline.

Practise

Run tabletop exercises where your team walks through a ransomware scenario. Gaps become obvious quickly.

Should you pay?

Paying does not guarantee recovery and encourages further attacks. Seek professional and legal advice and report incidents to the appropriate authorities.

The bottom line

Prevention reduces risk, segmentation limits damage and immutable backups with a tested plan ensure recovery. Managed Cloud and UbiFi security services cover each layer.
