Windows is the prime target for cyber criminals

Introduction: Why Windows Is a Prime Target

Microsoft Windows remains the backbone of most business environments. From desktops and laptops to servers and on-premise applications, Windows is the operating system of choice for over 70% of desktop users worldwide. While its widespread adoption offers standardisation and efficiency, it also makes Windows a primary target for cyber criminals.

In 2025, cyber threats are growing in scale, complexity, and frequency. Over 95% of all malware threats detected so far this year have targeted Windows systems. From phishing emails to sophisticated ransomware attacks, bad actors are relentlessly seeking vulnerabilities. One breach — even a minor one — can lead to costly data loss, downtime, reputational damage, and hefty fines under regulations like GDPR.

Whether you're a small business or a larger organisation, it's more important than ever to stay proactive. Let’s explore why Windows users are at risk, and what you can do to protect your business.

Why Windows Systems Are at Greater Risk

Windows' dominant market share makes it an attractive playground for hackers. But several factors increase the risk profile:

1. Legacy Systems and Outdated Software

Many businesses still rely on older Windows versions such as Windows 7 or Windows Server 2012 — both of which are no longer supported by Microsoft. These outdated systems lack critical security patches and are highly vulnerable to attack.

2. Misconfigured Systems

Improperly configured devices and servers often create open doors for attackers. Default settings, weak admin passwords, and unnecessary open ports can all be exploited.

3. Human Error

While tools can help, people are often the weakest link. Employees may unintentionally click on malicious links, download infected attachments, or use weak passwords.

4. Targeted Malware

Cybercriminals develop malware specifically engineered to exploit Windows vulnerabilities. This includes ransomware, trojans, rootkits, and more.

The Cost of a Cyber Breach

One successful attack can cause:

• Financial Losses: Downtime, system repair costs, and lost business can quickly add up. The average UK SME cyberattack costs £19,400.
• Reputational Damage: Clients may lose trust, especially if their data is compromised.
• Legal Trouble: Non-compliance with data protection regulations like GDPR can lead to fines in the tens of thousands.
• Operational Disruption: Even a brief outage can affect email, invoicing, file access, and customer service.

So how do you protect your business?

Key Steps to Protect Your Windows-Based Environment

1. Keep Software and Hardware Updated

Regular updates aren’t just annoying pop-ups — they’re your first line of defence. Make sure:

• Windows updates are applied automatically or scheduled weekly.
• Third-party applications (e.g., Adobe, Zoom, Chrome) are also patched.
• Legacy systems are upgraded or isolated from the network.

Outdated software is the #1 attack vector for ransomware.

2. Use Endpoint Protection & Firewalls

Invest in a reputable antivirus solution with real-time scanning, behaviour detection, and cloud-based threat intelligence. Couple this with:

• Next-Gen Firewalls (NGFWs) that monitor traffic at a deeper level
• Email filtering to stop phishing attempts
• Web filtering to block suspicious domains

Don't forget built-in tools like Windows Defender, which should be active and regularly monitored.

3. Enforce Strong Password Policies

Use complex passwords and enforce regular password changes. Better yet, implement Multi-Factor Authentication (MFA) across all systems and software — especially for email and cloud logins.

4. Train Your Team Regularly

Cybersecurity training shouldn’t be a one-off event. Your team needs to understand:

• How to spot phishing emails
• Why suspicious links and downloads are risky
• How to report unusual activity quickly

Tools like simulated phishing campaigns can also help reinforce awareness.

5. Create a Cyber Resilience Plan

Despite your best efforts, attacks may still happen. That’s why resilience is key. Your plan should include:

• Clear instructions for staff during a breach
• Who to notify (IT provider, clients, authorities)
• Data recovery steps (from backups or cloud systems)
• Isolation procedures (e.g., disconnecting infected machines)

Document everything and run drills at least twice a year.

6. Promote a Culture of Security and Reporting

Encourage your team to report anything unusual — no matter how small it seems. A suspicious email, strange pop-up, or system lag could be the early sign of a bigger problem.

Quick reporting enables faster response, which can drastically reduce the severity of an incident.
