The Dark Web
The Hidden Layer of the Internet
Beneath the familiar internet you use daily lies the Dark Web, a hidden layer not indexed by search engines like Google. Accessing it requires specialized software like Tor. Originally developed by the U.S. Navy in the 1990s, the Dark Web has since become a double-edged sword. It serves as a haven for privacy advocates, journalists, and whistleblowers, but it’s also a hotspot for cybercriminals involved in illegal activities.
While some use the Dark Web to bypass censorship or protect freedom of expression, it’s also a marketplace for stolen personal data, financial fraud, and illegal goods, making it a high-risk zone for identity theft.
To safeguard your personal data from being bought, sold, or leaked on the Dark Web, consider identity monitoring services that scan underground forums and databases for exposed information. Ensure your data stays out of dangerous hands by using these services to remove it from the internet.
Encryption
Securing Your Digital World
Ever wonder how your online banking information stays safe? The answer is encryption, a process that converts your data into a secret code, readable only by authorized parties.
How It Works:
- Turns data into unreadable text (gibberish if intercepted).
- Only the right system (your bank, email provider, etc.) can decrypt it.
Where You Use Encryption Daily:
- Secure web pages (look for HTTPS—the "S" stands for secure).
- Messaging apps like WhatsApp and iMessage use end-to-end encryption.
- Online banking and shopping to protect financial transactions.
Encryption keeps your private information safe from prying eyes. Check out additional tips on protecting your documents and maintaining privacy.
CAPTCHA
Proving You’re Human Online
If you’ve ever clicked traffic lights or typed distorted letters before logging into a website, you’ve encountered a CAPTCHA. This test, which stands for "Completely Automated Public Turing test to tell Computers and Humans Apart," is designed to distinguish people from automated programs like spambots.
Named after computer scientist and WWII codebreaker Alan Turing, CAPTCHAs ensure you’re human, not a bot. While older versions use puzzles, newer ones analyze your mouse movements to verify humanity.
However, not all CAPTCHAs are created equal. Be cautious of fake CAPTCHAs designed to install malware on your device. Learn how to spot them with our guide.
Spam
From Monty Python to Malware
The term spam for unwanted emails originates from a Monty Python sketch where the word "spam" is repeated incessantly, overwhelming a conversation. This term now describes the flood of unwanted emails cluttering inboxes.
Originally, spam was just annoying promotional emails and chain letters. Today, it’s a significant cybersecurity threat. Phishing emails, malware-laden attachments, and fraudulent schemes lurk in spam messages, tricking users into clicking malicious links or revealing sensitive information.
CC/BCC
Mastering Email Copies
If you’ve ever sent an email, you’ve likely seen the options for CC (Carbon Copy) and BCC (Blind Carbon Copy).
CC sends a copy of your email to someone to keep them informed, and everyone can see who’s CC’d.
BCC is private—recipients in this field receive the email, but their identities remain hidden. This is ideal for group emails where privacy is essential.
