Why January Is a Hacker’s Favourite Month (And How to Fight Back)

The post-holiday period is prime time for cyber attacks. Here’s your complete guide to starting 2026 securely.

The champagne has been popped, the fireworks have faded, and your team is trickling back into the office. But while you were enjoying the holiday break, cybercriminals were hard at work — and they’re counting on you being distracted.

January isn’t just about fresh starts and new resolutions. For Australian businesses, it’s one of the most vulnerable times of the year. Inboxes are overflowing, staff are still shaking off holiday mode, and security vigilance is at an all-time low.

Hackers know this. And they exploit it ruthlessly.

The Alarming Statistics Behind January Cyber Attacks

Before diving into solutions, let’s understand why January demands your immediate attention:

• 91% of cyber attacks begin with a phishing email — post-holiday inboxes are prime hunting grounds
• 43% of attacks specifically target small to medium businesses — hackers know SMBs often lack dedicated security resources
• $4.45 million is the average global cost of a data breach — up 15% over the past three years
• Phishing attacks surge by 52% in January compared to other months
• Australian businesses lost over $3 billion to cybercrime in 2024 alone

These aren’t abstract numbers — they represent real businesses forced to close, real employees losing jobs, and real customers having their data exposed. The question isn’t if your business will be targeted, but when.

Five Reasons Hackers Love the Post-Holiday Period

1. The Email Avalanche Effect

Your team returns to hundreds — sometimes thousands — of unread emails. In the rush to clear the backlog, it’s easy to click without thinking. That ‘urgent invoice’ or ‘password reset request’ hiding among legitimate messages? It could be a carefully crafted trap.

2. The Holiday Hangover

Let’s be honest — nobody’s operating at peak performance in the first week back. The mental shift from beach relaxation to spreadsheets takes time. Cybercriminals exploit this cognitive fog, knowing tired and distracted employees make more mistakes.

3. Unpatched Systems

While your office sat empty, software vendors released critical security patches, new vulnerabilities were discovered, and your systems went unmonitored. Without automatic updates configured, you may have started 2026 with weeks-old security holes wide open.

4. Lingering Access Issues

December often brings staff departures, but holiday chaos means access removal sometimes gets delayed. Former employees with active credentials — whether through malice or their compromised accounts — represent a significant and often overlooked risk.

5. Fresh Attack Campaigns

Cybercriminals launch new attack campaigns in January, testing fresh tactics and exploiting newly discovered vulnerabilities. They know security teams are stretched thin and incident response times may be slower than usual.

Your January Security Action Plan

Now for the practical steps. Here’s exactly what you need to do to protect your business:

Conduct a User Access Audit

Why: Orphaned accounts and excessive permissions are open doors for attackers.

How:

1. List all user accounts across every system — email, cloud apps, network access, financial software
2. Immediately disable accounts for staff who left during or before the holidays
3. Flag dormant accounts unused for 90+ days for review
4. Apply least privilege — users should only access what they genuinely need
5. Revoke any temporary holiday coverage access

Patch Everything — Now

Why: Unpatched software is the number one entry point for ransomware and malware.

How:

1. Update all operating systems (Windows, macOS) to latest versions
2. Patch web browsers — Chrome, Edge, Firefox, Safari
3. Update business applications: Microsoft 365, Adobe products, accounting software
4. Don’t forget firmware on routers, firewalls, and network devices
5. Enable automatic updates to prevent future gaps
6. Verify antivirus definitions are current

Verify Your Backups Actually Work

Why: Backups are worthless if they fail when you need them most.

How:

1. Confirm all scheduled backups completed successfully over the holiday period
2. Perform a test restore of critical files to verify data integrity
3. Check backup storage capacity for the year ahead
4. Ensure offsite/cloud backups are functioning
5. Document your Recovery Time Objective (RTO) and Recovery Point Objective (RPO)

Enable MFA on Everything

Why: Multi-factor authentication blocks 99.9% of automated attacks, even with compromised passwords.

Priority systems:

• Email (Microsoft 365, Google Workspace)
• Cloud storage (OneDrive, Google Drive, Dropbox)
• Remote access tools (VPN, remote desktop)
• Banking and financial applications
• Social media and domain registrars

Pro tip: Use authenticator apps (Microsoft Authenticator, Google Authenticator) rather than SMS codes where possible — they’re more secure.

Reset Your Team’s Security Mindset

Why: Your people are simultaneously your greatest defence and your biggest vulnerability.

How:

1. Send a company-wide reminder about phishing threats and warning signs
2. Share examples of recent scams targeting Australian businesses
3. Remind everyone of the procedure for reporting suspicious emails
4. Encourage password changes for anyone who used work devices personally over the break
5. Schedule formal security awareness training for Q1

Review Your Security Policies

Why: Outdated policies don’t protect anyone.

Key documents to review:

• Acceptable Use Policy — does it address current threats?
• Incident Response Plan — are contact details current?
• Business Continuity Plan — does it reflect your current operations?
• Privacy Policy — does it meet Australian Privacy Act requirements?

A Cautionary Tale: When Holiday Neglect Turned Costly

Consider this real scenario: A Melbourne professional services firm returned from Christmas to find their systems encrypted with ransomware. The attack occurred on December 28th while the office sat empty. The entry point? An unpatched vulnerability in their email server — a patch had been available since December 15th.

The fallout:

• Two weeks of client data permanently lost — backups hadn’t been tested and were corrupted
• $180,000 in recovery costs and lost revenue
• Three major clients moved to competitors
• Mandatory breach notification to all affected parties
• Cyber insurance premiums doubled at renewal

This attack was entirely preventable. Automated patching, tested backups, and basic holiday monitoring would have stopped it. Don’t let this be your story.

Five Things You Can Do in the Next 30 Minutes

Not everything requires a major project. Here are immediate actions:

1. Change your passwords — especially email, banking, and admin accounts
2. Enable MFA on your email — this takes 5 minutes and provides massive protection
3. Run Windows Update — on every computer, right now
4. Check your last backup — verify it completed and try restoring one file
5. Send a phishing reminder to your team — a quick email costs nothing

Setting Your 2026 Security Direction

January isn’t just about immediate fixes — it’s about establishing your security trajectory for the entire year. Ask yourself:

• Budget: Have you allocated appropriate funds for IT security?
• Insurance: Is your cyber insurance coverage adequate and current?
• Compliance: Are there new regulations you need to meet this year?
• Training: When will your team receive security awareness training?
• Technology: Are any critical systems due for replacement?
• Support: Do you have the right IT partner to navigate evolving threats?
