Protecting Your Business from Christmas Cyber Threats

As Christmas lights go up and businesses begin winding down for the festive break, cybercriminals are gearing up for their busiest time of the year. While most teams are enjoying seasonal celebrations, reduced staffing and an increase in online transactions create the perfect storm for cyberattacks. For organisations across the UK - and especially for SMEs relying on overstretched internal tech teams - this is a critical time to strengthen cybersecurity, boost cyber resilience, and ensure that holiday cheer doesn’t turn into a data breach.

At Fitzrovia IT, we see first-hand how significantly the threat landscape changes during December. Here’s what your business needs to know about festive cyber risks, why this period is so attractive to criminals, and what you can do to stay protected.

What Are the Cyber Risks at Christmas?

The holiday season brings with it a unique set of cybersecurity risks, many of which escalate because organisations are distracted, short-staffed, or simply less vigilant than usual. Some of the most common threats include:

1. Phishing and Smishing Scams

Cybercriminals know inboxes are full of parcel notifications, order confirmations, donation requests, and holiday offers - making it easier than ever to disguise malicious messages. Christmas-themed phishing emails increase significantly in December, often impersonating retailers, charities, or even senior colleagues rushing through "urgent" requests before they log off for the break.

The same applies to smishing attacks (SMS phishing), with fraudulent delivery texts being a major seasonal threat.

2. Ransomware Attacks

Ransomware groups know December is one of the worst possible times for an organisation to face downtime. With fewer IT staff available and tighter deadlines, companies are more likely to pay a ransom to restore access quickly. This makes businesses of all sizes prime targets.

3. Compromised Online Shopping

Company devices are more likely to be used for personal shopping in December - whether for Black Friday deals, last-minute gifts, or Christmas travel. Unsecured websites, malicious ads, or password-stealing malware are common entry points for attackers looking for a foothold into corporate networks.

4. Insider Threats and Human Error

Fatigue, distraction, and reduced oversight can lead to mistakes. Employees may connect to unsecured Wi-Fi while travelling, approve a suspicious invoice, or fall for a fake gift-card scheme. The festive period is the perfect environment for errors that can lead to security breaches.

5. Supply Chain Vulnerabilities

Many suppliers operate with skeleton crews during December. If a partner company suffers a breach, it can quickly extend to your environment. Supply chain attacks continue to rise year-on-year, making this a critical risk area for organisations seeking strong business continuity.

Why Do Cybercriminals Strike Now?

It’s simple: Christmas is the ideal time.

Reduced Staffing:

IT teams are often operating with limited cover. This means slower incident responses, delayed patching, and longer detection times - all of which benefit attackers.

Seasonal Distraction:

Staff are busy, rushing to finish projects before the break or juggling holiday commitments. Vigilance drops across the board.

Financial Pressure:

Criminals know that organisations cannot afford downtime during peak trading periods or year-end reporting. They count on the urgency to push companies into making poor decisions.

Spike in Digital Activity:

Online shopping increases. Charity donations increase. Email traffic increases. Every digital touchpoint becomes a potential attack vector.

In short, Christmas provides both opportunity and leverage, making it one of the most dangerous times of year for cyberattacks.

How Your Organisation Can Protect Itself This Christmas

While the festive season opens the door to increased threats, the good news is that the right measures can significantly reduce your risk.

1. Educate and Enable Your Team

Regular reminders about phishing, safe online shopping, and secure password practices go a long way. Even a short pre-Christmas refresher session can drastically reduce human error.

2. Implement Multi-Factor Authentication Everywhere

MFA remains one of the most effective ways to block unauthorised access - even if credentials are stolen in a holiday-themed phishing attack.

3. Strengthen Email Security

Advanced filtering, anti-phishing tools, and DMARC implementation can block suspicious emails before they ever reach staff.

4. Keep Systems Patched and Updated

Ensure critical updates are installed before staff go on leave. Outdated software is one of the easiest ways for cybercriminals to get in.

5. Review Remote Access Policies

With more staff working remotely during December, make sure VPNs, endpoint protection, and secure Wi-Fi requirements are enforced.

6. Test Your Backups

A ransomware attack is only as damaging as your last backup. Make sure your backups are encrypted, off-site, and regularly tested.

7. Have an Incident Response Plan Ready

If something does go wrong, a rehearsed plan is essential. Knowing who is on call, what steps to take, and how to contain a breach saves valuable time.
