The 5 Key Stages of a Cyber Attack and How to Protect Your Business
If you’ve ever had your email hacked or your computer acting a bit dodgy, you’ve already brushed shoulders with the beginning of a cyber attack. Whether you’re running a small trade business or managing a growing team in the city, understanding how these attacks unfold can be the difference between a quick recovery or a costly clean-up.
Stage 1: Reconnaissance – The Quiet Scout
Before anything goes bang, cybercriminals usually start by doing their homework. This stage is all about gathering information. Think of it like a thief walking past your house every day to see when you leave, where the spare key might be, and which window doesn’t lock properly.
They might be checking your company’s website, LinkedIn profiles, or even your social media to learn about your staff, tech stack, and suppliers. The goal? To find a way in.
Protect your business: Train your team to limit the personal info they share online and regularly audit public-facing assets. Tools like network traffic monitoring can help detect unusual activity early.
Stage 2: Weaponisation – Loading the Arsenal
Once enough info is gathered, attackers craft their plan. This could be a phishing email with a malicious attachment or a website that delivers malware when visited. Ever received an email from “yourself” asking you to click a link? That’s a classic sign of this stage.
Protect your business: Teach staff how to spot dodgy emails (check out our post on smishing scams) and consider a robust email filtering system. Antivirus and anti-malware software should always be up to date.
Stage 3: Delivery – Making the Move
This is where the attack is delivered. Could be via email, a compromised USB, or even a dodgy browser extension. It’s the moment the criminal knocks on your digital front door—or slips in through a window.
Protect your business: Use application control and browser extension management. We’ve covered this in more detail in our guide on the dangers of browser extensions and application control in the Essential Eight.
Stage 4: Exploitation – The Breach
If the delivery is successful, the attacker now tries to exploit a vulnerability. This can be as simple as an outdated bit of software or a weak password. Once inside, they might install malware, ransomware, or quietly collect data.
One of our clients, a small accounting firm in Brisbane, learned this the hard way. One employee used the same password across multiple sites. A breached third-party site led to their work email being compromised, which then gave access to sensitive client files. It was a stressful week, but they’ve since implemented multi-factor authentication (MFA) and password managers to prevent it happening again.
Protect your business: Keep all systems patched and up to date. Enforce strong password policies and use MFA wherever possible. Regular cybersecurity training is essential—learn more about that here.
Stage 5: Installation and Command – The Real Damage
This is where things get ugly. The attacker installs their tools, maybe sets up a backdoor (so they can come and go as they please), and begins exfiltrating data or disrupting operations. Think stolen customer information, locked files, or even full access to your systems.
Protect your business: Implement endpoint detection and response (EDR) tools and have a solid incident response plan in place. Also, if you haven’t already, it’s worth checking out our breakdown of cybersecurity plans for businesses.
