Ransomware has quickly become one of the most disruptive cyber threats facing Australian businesses. It can lock you out of your own systems, encrypt important files and bring your entire operation to a halt within minutes. The experience is stressful, unexpected and costly for any organisation.

The good news is that most ransomware damage can be prevented with the right habits, tools and preparation. Understanding how these attacks work and what to do if something goes wrong gives you a far better chance of keeping your business safe.

What ransomware actually is

Ransomware is malicious software designed to block access to your data. Once it gets onto a device or network, it locks your files and demands payment in exchange for restoring access. The attackers often leave a note on your screen telling you what has been encrypted and how much they want.

These attacks can target anyone. You do not need to be a large organisation or have valuable data. Many cybercriminals simply look for easy opportunities.

How ransomware usually gets in

Ransomware rarely arrives through complicated hacking. In many cases, it enters through small, everyday actions that seem harmless at the time.

Some of the common pathways include:

• clicking links in suspicious emails
• downloading files from unknown senders
• visiting compromised websites
• using weak passwords
• running outdated software
• connecting infected USB drives

Once it gets inside a device, the malware quickly begins locking files so you can no longer open them. The spread can be slow and silent or fast and aggressive, depending on the type of ransomware.

Understanding where attacks begin helps you avoid the simple mistakes that allow them to succeed.

How to prevent ransomware attacks

A strong ransomware defence starts long before an attack. Small preventative measures can make a
major difference.

Keep your systems updated

Updates often contain security fixes. Without them, attackers can walk through known weaknesses. Make sure your operating system, apps and software tools are updated regularly.

Use reputable security software

Good antivirus and anti-malware programs can detect threats before they cause damage. These tools should run constantly in the background and update automatically.

Be cautious with email

Many ransomware attacks start with convincing-looking emails. If something feels off, do not open it. Avoid downloading attachments unless you are certain they are safe.

Back up your data consistently

Backups give you a lifeline. If ransomware hits, you can restore clean versions of your files and avoid paying a ransom. Store backups off-site or in secure cloud services not directly connected to your
main system.

These simple habits can significantly reduce your risk.

What to do if you think you have ransomware

Even with strong protection, no system is completely immune. If you suspect an attack, act quickly to limit the damage.

Disconnect from the internet

Turning off your Wi-Fi or unplugging your ethernet cable helps stop the malware from spreading to other devices in your network.

Do not pay the ransom

Paying offers no guarantee that you will receive your files back. It also funds future attacks. Cyber security experts strongly advise against paying.

Report the incident

Inform your national cyber security centre or local authorities. Reporting helps track threats, and you may receive guidance on recovery.

Use backups to restore data

If you have safe, recent backups, they can help you get up and running again without negotiating with
the attacker.

Responding early can prevent a minor incident from escalating into a full disruption.

Extra precautions for businesses

Businesses have more at stake, so stronger protection is essential.

Train your team

Human error is the top cause of ransomware infections. Training staff to recognise suspicious emails or unusual behaviours can stop many attacks before they start.

Strengthen password practices

Use longer, unique passwords for every account. Multi-factor authentication adds another layer
of protection.

Limit staff access

Not everyone needs access to everything. Restricting permissions helps contain an infection if it occurs.

Prepare an incident response plan

A clear, documented plan helps your team move quickly and confidently during an attack. Practising your response reduces confusion and downtime.

Preparation reduces panic and prevents small issues from becoming major problems.

How ransomware is evolving

Cybercriminals are constantly adapting their tactics, which means businesses must stay alert.

Mobile and tablet attacks

Phones and tablets are now common targets. Treat them with the same care as your computers.

Double extortion

Some attackers now steal your data before locking it. They threaten to release private information unless you pay, increasing the pressure on victims.

Attacks on cloud accounts

Cloud storage is not immune. Weak passwords or poor security settings can give attackers easy access.

Staying informed helps you respond early and protect your business more effectively.

FAQs about ransomware protection

How often should I back up my data

Daily or weekly, depending on how often your information changes. Off-site or cloud backups are ideal.

Is it ever safe to pay the ransom

No. Payment does not guarantee your files will be returned and encourages further attacks.

What is the biggest cause of ransomware infections

Human behaviour. Outdated software, weak passwords and unsafe email habits remain the most
common causes.

Stay protected with proactive security

Ransomware is a serious threat, but you are not powerless. With the right preventative measures, clear processes and ongoing awareness, you can greatly reduce the impact of an attack. A secure business is one that stays updated, stays cautious and stays prepared. Contact us at JohnCruz IT Today.
