The key to protecting yourself is understanding the enemy. Here is an easy-to-understand breakdown of the most common cyber threats and simple ways to stay safe.

1. The Most Common Attacks

Cybercriminals use various methods, but most attacks fall into a few major categories:

Phishing

What it is: A scam where an attacker disguises an email, text message, or phone call as a trustworthy source (like your bank, a favorite store, or a work colleague).

How it works: The message tricks you into clicking a malicious link, opening an infected attachment, or giving up sensitive information like passwords or credit card numbers. It's like a digital fishing expedition, casting a wide net, hoping someone takes the bait.

Example: An email that looks exactly like it's from your bank, saying, "Your account has been frozen! Click here to verify your identity."

Malware/Spyware (Malicious Software)

What it is: A blanket term for any harmful software designed to disrupt, damage, or gain unauthorized access to a computer system.

How it works: It sneaks onto your device, often through a phishing email, a dodgy download, or an infected website. Once installed, it can spy on you, slow down your system, or encrypt your files. Ransomware is a type of malware that locks you out of your files (encrypts them) and demands payment (ransom) to unlock them. Viruses attach to a clean file and spread, damaging system functionality. Spyware secretly monitors and records your activity, like your keystrokes and passwords.

Example: Clicking a link that automatically downloads a program that suddenly encrypts all your photos, demanding money for the key to decrypt them.

DDoS Attacks (Distributed Denial of Service)

What it is: An attack aimed at shutting down a website or online service.

How it works: The attacker floods the target server with a massive, overwhelming amount of fake traffic (like thousands of people rushing a single small door at the same time). The server can't handle the load, slows to a crawl, and eventually crashes, denying service to real users.

Example: A popular online store's website suddenly becomes inaccessible during a major sales event.

2. Simple Steps to Stay Protected

The best defense is often simple cyber hygiene. You don't need to be a tech expert to be secure.

Strengthen Your Passwords and Access

Use Strong, Unique Passwords: Never reuse passwords! A strong password is long (12+ characters), uses a mix of uppercase, lowercase, numbers, and symbols, or is a memorable passphrase.

Enable Multi-Factor Authentication (MFA): This is the single most important step. MFA requires a second piece of verification (like a code sent to your phone or a fingerprint scan) in addition to your password. Even if a criminal steals your password, they can't get in without your phone.

Be Skeptical of Messages

Check the Sender: Look closely at the sender’s email address—scammers often use slight misspellings (ex, “support@paypa*.info” instead of “support@paypal*.com”).

Never Click Suspicious Links or Attachments: If a message seems urgent, too good to be true, or asks for sensitive information, treat it with extreme caution. If it claims to be from a company you use, navigate to their official website directly (don't click the link in the email) and log in to check your account.

Keep Everything Updated

Update Your Software: When a company releases a software update (for your phone, computer, or apps), it often includes patches for security vulnerabilities that attackers might exploit. Delaying updates leaves the door open for criminals.

Use Antivirus/Antimalware Software: Install reputable security software on your computer and keep it updated to catch and remove malicious programs.

Back Up Your Data

Regularly Back Up: Make copies of your most important files and store them in a secure, separate location, like an external hard drive or a cloud service. If you're ever hit by ransomware, you can wipe your computer and restore your files without paying the ransom.
