The Most Wonderful Time of The Year… For Cyber Criminals
For many businesses, Christmas means reduced staffing levels, employees taking annual leave and a welcome opportunity to disconnect from work.
For cyber criminals, however, it presents a different opportunity.
The festive period often creates the perfect conditions for cyber attacks. With fewer employees available to monitor systems, increased volumes of personal deliveries and a rise in out-of-office messages, businesses can become easier targets for phishing, ransomware and account compromise.
Before your team signs off for the holidays, it’s worth understanding why Christmas presents such a significant cyber security risk.
1. Reduced Staffing Makes Attacks Easier to Miss
Many organisations operate with significantly reduced staffing levels over Christmas. Whether employees are taking leave or businesses are partially closed, fewer people are available to identify suspicious activity and respond quickly to incidents.
This can create longer detection times and give attackers more opportunity to move through systems unnoticed.
A ransomware attack discovered on Boxing Day may have gone undetected for several days before anyone is available to investigate.
2. Cyber Criminals Know Employees Are Expecting Deliveries
December brings a sharp increase in parcel deliveries, creating an ideal environment for phishing scams.
Attackers often impersonate delivery companies such as:
- Royal Mail
- DPD
- Evri
- Amazon
Employees expecting Christmas deliveries are more likely to click a link without questioning whether the message is genuine.
These scams are commonly used to steal Microsoft 365 credentials, payment information or install malware on devices.
3. Out-of-Office Messages Can Reveal More Than You Think
Out-of-office replies are useful, but they can also provide valuable information to attackers.
A typical automatic response may reveal:
- Who is unavailable
- When they will return
- Their job role
- Alternative contacts within the organisation
This information can help cyber criminals identify potential targets and craft more convincing phishing emails.
Keep out-of-office messages simple and avoid sharing unnecessary details.
4. Holiday Periods Are a Common Time for Ransomware Attacks
Attackers often look for periods when businesses are operating with fewer resources.
Weekends, bank holidays and Christmas shutdowns can provide a larger window of opportunity before a threat is detected and contained.
If backups haven’t been tested recently or incident response plans are unclear, recovery can become far more difficult.
5. Employees Are Often More Distracted
Between year-end deadlines, Christmas events and holiday preparations, employees have more competing priorities than usual.
Cyber criminals rely on these moments of distraction.
Urgent payment requests, fake invoices, account verification emails and phishing messages can appear legitimate when employees are moving quickly between tasks.
Even organisations with strong technical controls can be vulnerable if user awareness is lacking.
How Businesses Can Reduce Cyber Risk Before Christmas
Fortunately, a few practical steps can significantly reduce your exposure:
✅ Enable Multi-Factor Authentication (MFA) for all users
✅ Remind employees about Christmas phishing scams
✅ Review out-of-office message content
✅ Verify that backups are working correctly
✅ Apply outstanding security updates
✅ Confirm incident response procedures
✅ Ensure appropriate monitoring remains active during holiday periods
