Module 2: Understanding Cyber
Threats
Welcome to Module 2!
As we dive into the complex world of cyber threats, our focus will be on truly understanding the mechanisms behind the common and emerging threats. By the end of this module, you’ll not only be able to identify these threats but also understand how they operate and what you can do to protect against them.
2.1. Types of Cyber Threats
Malware - Your Computer’s Worst Enemy:
- What is Malware? Malware is any software intentionally designed to cause damage to a computer, server, client, or computer network. This includes viruses, worms, and Trojans.
- How It Works: A virus attaches itself to clean files and infects other clean files. Worms burrow into your systems and replicate themselves, while Trojans disguise themselves as legitimate software.
- Protection Measures: Always keep your software updated, use reputable antivirus software, and never download files from unknown sources.
Phishing - The Art of Deception:
- Recognizing Phishing: Phishing attacks use deceptive emails or messages that mimic legitimate sources to steal sensitive data. These messages often urge you to click on a link or open an attachment.
- Defense Strategies: Verify the sender’s information before responding to emails. Look for signs of legitimacy, such as correct spelling and grammar, and hover over links to see where they really lead.
Ransomware - The Digital Kidnapper:
- Understanding Ransomware: This type of malware locks you out of your own files by encrypting them, then demands payment in exchange for the decryption key.
- Preventive Tips: Backup your data regularly on different media or cloud storage, which can be a lifesaver. Use strong, updated security software to protect your systems.
Cryptojacking - Silent but Deadly:
- Cryptojacking Explained: Hackers use your computing resources to mine cryptocurrency without your permission. This can significantly slow down your devices and increase your electricity bills.
- Spotting and Preventing Cryptojacking: Watch for unusually high processor usage on your devices, which is a common symptom. Install ad-blocking or anti-crypto mining extensions on web browsers to prevent scripts from downloading.
How Does Cyber Attacks Happen?!
- STEP 1: Infection Vector - Most attacks start with a phishing email or a visit to an infected website. Understanding these vectors helps you guard against them.
- STEP 2: Exploitation - Once the malware is on your system, it exploits vulnerabilities to execute its malicious actions. This can involve stealing data, corrupting files, or other damaging activities.
- STEP 3: Payload Delivery - This is the delivery of the harmful part of the malware. For example, ransomware will start encrypting your files at this stage.

Understanding and Defending Against Common Vulnerabilities:
> Software Flaws: Regularly update your software to fix bugs that could be exploited.
> Weak Passwords: Use complex passwords and consider a password manager to generate and store them securely.
> Unsecured Wi-Fi Networks: Always use a VPN when connecting to public Wi-Fi networks to encrypt your data.
“The Human Factor”
Human Errors and How They Lead to Security Breaches:
- Social Engineering: Attackers often use psychological manipulation to trick people into making security mistakes or giving away sensitive information.
- Best Practices: Always verify identities before sharing information. Be skeptical of unsolicited phone calls, visits, or email messages from individuals asking about family, friends, employees or other internal information.
Creating a Secure Environment:
- Education is Key: Conduct regular training sessions to keep security practices fresh in the minds of your family, friends, and employees.
- Promote Good Cyber Hygiene: Encourage habits like logging off when not using devices and being cautious about email attachments and links.
Module 3:
Protecting
Your
Digital Footprint
Welcome to the Wild World of Protecting Your Digital Footprint: “A Guide to Not Being Digitally Naked Online.”
Alright, buckle up, tech aficionados and digital daredevils, for a riveting ride through the cyber jungle, where your digital footprint is bigger than Bigfoot's and potentially just as mythical if you don't play your cards right. Welcome to Module 3!
First off, let's talk Passwords.
Yes, passwords – the digital equivalent of locking your door with spaghetti if you're not careful.
The cardinal sin? "123456" or "P@ssword".
Seriously, if these are your go-to's, you might as well hand over your digital keys to the first cyber crook you meet in a dark alley of the internet.
So, What's the Secret Sauce to a
“Strong Password”?
Think of it as concocting a magic potion. Mix in uppercase letters, lowercase letters, numbers, and symbols like you're a wizard crafting a spell. And for Merlin's sake, make it longer than your grocery list. Twelve characters should be your starting point, not the finish line.
two-factor authentication (2FA)
what is 2fa?
Imagine if every time Batman entered the Batcave, Alfred asked for a secret handshake. That's 2FA in a nutshell.
It adds an extra layer of "You shall not pass!" to your accounts. Even if some villain manages to guess your password, they'd still need to get past this ”Digital Alfred” (i.e. 2FA). This could be a code sent to your phone or an authentication app that generates temporary codes faster than you can say "Holy cybersecurity, Batman!"
safe browsing habits
The internet is a buffet of information, but not everything on the menu is good for you. Clicking on random links is like eating mystery meat – it might be fine, but do you really want to take that risk?
Stick to trusted websites, and if your browser starts throwing red flags at you like you're running with the bulls in Pamplona, maybe don't proceed.
And for those moments when you're tempted to wade into the murkier waters of the web, consider using a Virtual Private Network (VPN).
A VPN is like a cloak of invisibility for your internet activity, making it harder for would-be snoops to track your online gallivanting.
Speaking of snooping, let's chat about Social Media
Ah, social media, where oversharing is considered a sport. Here's a thought: maybe don't broadcast every detail of your life.
Cybercriminals love to piece together information like they're assembling a jigsaw puzzle.
Before you know it, they've got a complete picture of you, and not in a fun, jigsaw puzzle kind of way. Be selective about what you share and with whom you're sharing.
Your breakfast choices might fascinate your followers, but they're also a feast for folks with foul intentions.
Please Remember:
Protecting your digital footprint isn't just about locking down your cyber life with passwords and 2FA, though they're a stellar start.
It's about being mindful of where you step online, whom you invite into your digital house, and keeping that house in tip-top shape with regular updates. So, go forth, secure your digital domain, and remember: in the grand internet safari, it's better to be the hunter than the hunted.
And now, for a parting thought:
If your password is still "password",
Might I suggest "P@ssword123"???
Just kidding. Please don't!!!
But seriously, how about adding a sprinkle of humor to your password creation process? Maybe something only you would chuckle at every login. Because if you've got to keep cybercriminals at bay, why not have a laugh while you're at it? 🤣
