AUSCI – CYBER SECURITY HELP DESK 24×7

If You’re Reading This During an Active Incident

Stop. Don’t restart affected systems. Don’t wipe anything. Don’t pay a ransom without advice. These actions — however instinctive — can destroy forensic evidence and make recovery harder.

Call us immediately. We’ll tell you exactly what to do right now.

What Is Incident Response?

Incident response is the structured process of detecting, containing, investigating, and recovering from a cyber security event. It’s what separates a manageable incident from a business-ending one.

When something goes wrong, most organisations make it worse — not through incompetence, but through panic. Systems get wiped before forensics can run. Breaches spread because containment is delayed. Ransoms get paid before alternatives are properly explored. Critical evidence is lost.

AusCi’s incident response engagements follow a proven methodology: contain the damage first, investigate the cause second, recover operations third, and fix the underlying problem so it doesn’t happen again.

Incidents We Respond To

Ransomware & Malware

Encrypted systems, ransom demands, propagating malware. We contain the spread, assess the scope, advise on payment decisions, and manage the recovery process — including restoring from clean backups where available.

Data Breaches & Unauthorised Access

Suspicious logins, data exfiltration, compromised accounts. We identify the access vector, determine what data was accessed or exfiltrated, contain ongoing access, and support your Notifiable Data Breach reporting obligations.

Business Email Compromise & Fraud

CEO fraud, invoice redirection, compromised email accounts. We investigate the scope of the compromise, contain it, and coordinate with your finance and legal teams on next steps — including recovery where possible.

Our Response Methodology

Phase 1 — Contain

The first priority is stopping the bleeding. We identify affected systems, isolate them from the rest of the environment, revoke compromised credentials, and block active attack vectors. The goal is to prevent the incident from getting larger while preserving evidence.

Phase 2 — Investigate

With containment in place, we investigate: what happened, when it happened, how the attacker got in, what they accessed or did, and whether they’re still present. Forensic analysis of logs, systems, and network traffic. Timeline reconstruction. Root cause identification.

Phase 3 — Recover

We work with your team to restore operations — rebuilding affected systems from clean sources, restoring data from verified backups, and validating that the environment is clean before systems are brought back online. Recovery is sequenced by business priority.

Phase 4 — Post-Incident Review

Once you’re operational, we review the incident in full: what the root cause was, what controls failed or were absent, and what changes are needed to prevent recurrence. This isn’t a blame exercise — it’s the work that makes the incident mean something.

The Best Incident Response Is One You Never Need

Incident response is reactive by definition. If you’re engaging us here, something has already gone wrong. Once we’ve helped you through it, the question becomes: how do we make sure this doesn’t happen again?

AusCi’s managed security monitoring and vCISO services are specifically designed to detect and disrupt attacks before they become incidents. Our Essential Eight services close the technical gaps most attackers exploit. And if your backups aren’t where they need to be, our remediation team can fix that before ransomware makes it matter.

Frequently Asked Questions

Do you offer 24/7 cyber security incident response?

Yes. Cyber incidents don’t wait for business hours and neither do we. Contact us via the emergency line on our contact page for out-of-hours response.

How quickly can you be on-site if needed?

Most incident response begins remotely — faster and often sufficient. Where on-site presence is required, availability depends on location. We’ll advise during initial triage.

Should we pay the ransom?

This is a decision we take seriously and advise on carefully — it depends on whether you have clean backups, the type of ransomware, the credibility of the threat actor’s decryption capability, and your legal and insurance obligations. We don’t have a blanket answer, but we’ll help you make an informed decision quickly.

Are we required to report a data breach?

Under Australia’s Notifiable Data Breaches (NDB) scheme, if a breach is likely to result in serious harm to individuals whose information was involved, you must notify the OAIC and affected individuals. We’ll help you assess your obligations and manage the notification process.

Will this affect our cyber insurance?

Notify your insurer as early as possible — most policies require prompt notification. We can liaise with your insurer and provide the documentation they need. If you don’t have cyber insurance, this is a good time to think about it.

Can you help us if the incident happened weeks ago and we didn’t know?

Yes. Dwell time — the period between initial compromise and detection — is often measured in weeks or months. Late detection doesn’t mean it’s too late to respond properly. We’ll investigate from the point of detection backwards.
