What To Do When a Cyber Breach Happens

Picture this: It’s 8:30AM in Darwin and you’ve just started work for the day. Staff can’t access shared files, and emails are bouncing. Then, a ransom note appears on screen demanding payment before you can get access to systems and data back.

Sounds scary right? The truth is this can and does happen to Northern Territory businesses, and small and regional operators aren’t immune. When this is today’s reality, it’s essential to know what you should do in this scenario and how prepared you are.

If you’re ready to get on the front foot, keep reading.

How to Know If You’ve Been Breached

With many local businesses operating with lean teams and older infrastructure, it’s hard to detect a breach early on – especially if you don’t have 24/7 cyber security monitoring. These are common signs a breach may have occurred:

• Locked files and a ransom message (resulting from a ransomware attack).
• Suspicious logins from unfamiliar devices or locations.
• Email compromise, and staff locked out of their email accounts.
• Customers reporting strange messages or requests, that are sent from your team’s email accounts but not by your team.
• Systems running unusually slow.

Next Steps to Take Immediately

A cyber breach is understandably stressful, so it’s important to know which steps to take and what’s important in this situation. You should:

1. Isolate affected systems: Disconnect the affected devices from the network.
2. Don’t delete evidence: It’s easy to panic, but you should never wipe machines or reboot services.
3. Contact your IT provider immediately: If you don’t have an IT provider, you should contact a cyber security professional.
4. Assess scope and impact: Take stock of what’s been affected, including data and users.
5. Understand reporting obligations: Know whether the breach needs to be reported. This might include the OAIC’s Notifiable Data Breach scheme, or other industry-specific compliance obligations.

Why NT Businesses are Vulnerable

It’s a common myth that regional businesses don’t need to worry about cyber attacks. In fact, they often face more challenges than their city-based counterparts, which can make them an easy target for cyber criminals. These challenges include:

• Remote sites, with limited on-site IT to understand and implement cyber security measures.
• Ageing infrastructure that’s harder to protect.
• Adopting new technology solutions, without increasing security maturity aligned to new risks.
• The partial implementation of cyber security frameworks (like the Essential Eight).

The Cost of a Cyber Breach

The effects of a cyber security breach are far reaching, and they can leave you dealing with long-term consequences They include:

• Downtime, which can lead to missed deadlines, delayed shipments or services, and leave your team waiting around. This is a significant concern for logistics-heavy businesses in the NT.
•  A damaged reputation, which can have a serious impact when you’re operating in small communities where word of mouth plays a big part in growing your business or holding it back.
• Breaches of contract for organisations with a government tender or defence suppliers.
• Financial loss in the form of compliance penalties, lost productivity, and remediation and data recovery costs.
• Cyber security insurance claims being denied, if your business didn’t have the right protections in place.

How To Be Prepared

Want to protect your business? With the right measures in place, you can significantly reduce the risk of a cyber security breach and avoid all of the devastating consequences. Here’s what you can do to proactively safeguard systems and data.

1. The Essential Eight
   This cyber security framework was designed by the Australian Signals Directorate, and creates a baseline to protect your business against common cyber threats. It includes three maturity levels you can aim for, and you can progressively align your defences with the level that matches your security needs.
2. 24/7 monitoring
   Cyber criminals don’t operate within your business hours. Monitoring for threats around the clock is critical, because attacks often happen when there’s no one online – including on weekends, public holidays, and festive periods. When you can spot threats early, you can stop them early as well – which means there’s less (or no) damage done.
3. Regular, tested backups
   Running regular data backups is critical to ensure you can get back up and running fast if data is lost or damaged during a cyber attack (such as ransomware). This is why testing backups is so important – when you’re depending on them to support business continuity, you want to make sure everything’s working when disaster strikes.
4. Cyber Awareness Training
   Many cyber threats rely on people making mistakes. This is known as human error, and it might look like someone clicking the wrong link or not thinking before sending off sensitive information, confirming log in credentials, or paying an invoice. Human error plays a part in most cyber attacks – but you can reduce risk by delivering regular Cyber Awareness training for your staff. This should cover common threats, what they look like, and how you can avoid falling victim. It also supports a stronger culture of cyber security, where threats are spotted, avoided, and reported.
5. Incident Response Planning
   If something happened today, who would you call? An Incident Response Plan is key to guide your response to a cyber security breach, so you’re not left dealing with guesswork and added stress. It includes instructions for how you should respond, and should cover roles and responsibilities, policies, tools, and steps for containment, threat mitigation, and recovery.

The Local Advantage

Cyber breaches are no longer a matter of if, but when. Staying prepared is critical to minimise the risk of downtime, financial and data loss, reputational damage, and regulatory fines. If you’re hit by a breach, you don’t want to be left panicked and looking for a cyber security expert who doesn’t understand your IT environment. The best approach is partnering with a local team who works alongside you, understands your business, and delivers proactive security measures and responsive support when suspicious activity is identified.
