Understanding security threats online
Introduction to cyber threats
What is a cyber threat?
A cyber threat is any activity that tries to harm your devices, data, or online activities. Cybercriminals can steal your personal information, disrupt your work, or trick you into giving away money.
Why does it matter?
Think about everything you do online: banking, shopping, talking to friends, or working. Now imagine if someone gained access to it all. Cyber threats can affect your finances, privacy, and even your identity.
Your digital life
Take a moment to think:
• Do you use the same password across multiple accounts?
• Have you received an email or text that seemed suspicious?
• Do you know how to spot a scam?
If these questions made you stop and think, you’re not alone. Cyber threats are a problem everyone faces, but there are steps you can take to stay safe.
How do cyber threats happen?
Cyber threats can affect anyone, anywhere, and they usually occur through two main methods, tricking you and exploiting technology. Let’s break these down further:
Tricking you (Social engineering)
Cybercriminals often rely on manipulating people into giving up sensitive information or access. These methods are designed to catch you off guard:
- Phishing emails and messages: Fake emails or texts that pretend to be from trusted organisations (like your bank or a delivery service) asking for personal information or urging you to click on a link
- Phone scams (vishing): Calls where someone pretends to be a legitimate company, pressuring you to share details or make payments
- Fake websites: Sites that look real but are designed to steal your information when you log in or make a purchase
- Impersonation: Criminals posing as someone you know to get money or information.
Think about this: Have you ever been contacted by someone claiming you owe money, asking for urgent action? How did you respond?
Exploiting technology
This method targets weaknesses in the devices and software you use. Criminals use tools and malicious programs to access your systems without your knowledge:
- Malware: Harmful software, such as viruses, ransomware, and spyware, designed to damage or steal from your devices
- Unsecured networks: Public WiFi can be an easy target for hackers to intercept your information
- Outdated software: If you don’t update your devices, criminals can exploit known security flaws to gain access
- Weak passwords: Using simple passwords makes it easier for hackers to guess them and access your accounts.
Real-world example: Hackers often target businesses with ransomware attacks. They encrypt files and demand payment to unlock them. This could happen to individuals too, like locking your family photos or important documents.
Here’s an example. Imagine you get an email like this:
Subject: “Urgent! Your bank account will be locked in 24 hours!”
What can you do right now?
Here are three quick steps to protect yourself:
1. Think before you click. Take your time with unexpected emails or messages
2. Keep software and apps updated. Updates fix security issues that criminals exploit
3. Use strong, unique passwords for each account: e.g. Apple21Candle63River92.
