12 May 2025 - Most people are familiar with terms like "viruses" or "hackers" when it comes to internet security, but the Dark Web and the cybercrime economy still feels mysterious and distant when it comes to safe online use. The Dark Web is a hidden part of the internet that can’t be found using traditional search engines and requires special software to access, often used for anonymous communication and, unfortunately, illegal activity. In this post, we will help you get a basic understanding of the Dark Web and how criminals operate inside it, so that you can be knowledgeable and take the necessary precautions to protect your identity, privacy, and data.
What is the Dark Web and how can it be accessed?
The Dark Web is a hidden part of the internet that doesn’t show up when you search with normal tools like Google. It requires users to download special software like Tor (The Onion Router) or I2P (Invisible Internet Project) to gain access. These tools anonymise people's location and online activity, making it difficult to trace users - a feature heavily exploited in identity theft and data breaches. While not everything on the Dark Web is illegal, it is often used for serious cybercrime, such as selling stolen credit card details, leaked passwords, fake ID documents, illegal drugs, and even hacking services.
How does the Dark Web facilitate cybercrime activities?
As mentioned above, cybercriminals use the Dark Web to buy and sell personal data, login credentials, credit card details, and hacking tools. But it goes even further. Entire darknet marketplaces operate like black-market versions of eBay or Amazon, where users can trade in malware, ransomware kits, counterfeit documents, and even stolen medical records. These platforms often include user ratings, escrow services, and customer support, making it easier and safer for criminals to do business.
Because these sites are hidden from regular search engines and protected by layers of anonymity, they are difficult for law enforcement to track. This level of secrecy creates a thriving underground economy, where digital crime can be carried out with low risk and high reward.
What’s the impact of Dark Web marketplaces on cybersecurity?
These marketplaces pose a serious threat to everyone, from individuals to global corporations. Once your personal data is leaked, it can be sold and resold, leading to identity theft, fraud, or unauthorised access to your accounts - all common outcomes of stolen credentials circulating on the dark web. This increases the need for proactive identity protection and real-time security alerts.
How can I protect myself and my family at home?
Staying safe from the risks of the Dark Web starts with good digital habits, the right tools, and adopting a Zero Trust security approach that assumes no device or user is automatically trustworthy — learn more about Zero Trust security here.
Here are some practical steps you can take to protect yourself and your family:
- Use strong, unique passwords for all your accounts, ideally with a password management tool, and avoid reusing the same password across multiple platforms.
- Enable two-factor authentication (2FA) wherever possible to add an extra layer of security.
- Invest in a trusted cybersecurity solution like ESET Home Security Ultimate, which includes Advanced Identity Protection, Secure Browsing and Anti-phishing Tools and Dark Web Monitoring to alert you if your personal data is found online.
- Have open conversations with younger family members and teens about smart home vulnerabilities, in your household who have personal laptops and devices. Speak to them openly about the dangers to their personal data if they choose to access this side of the internet.
- Be aware of and become familiar with the names of the various software family members may download to access the Dark Web, so that you are aware of their online activities and risks.
Being proactive and informed is the best defence against the hidden dangers online.

What role does anonymity play?
Understanding the role of anonymity in Dark Web operations helps you realise why it's so hard to track down cybercriminals. The Dark Web is designed to keep users hidden. Special software routes internet traffic through multiple servers around the world and uses strong encryption at every step. This creates layers of privacy, similar to peeling an onion, which is why it's often called "onion routing." Because of this, cybercriminals can operate with a high level of confidence that they won’t be identified. They can communicate, share stolen data, and conduct illegal transactions without revealing who they are or where they're located. This level of secrecy makes it extremely challenging for authorities to trace and stop them.
That’s why prevention is key. Using tools like ESET Home Security Ultimate, which offers real-time protection, identity monitoring, and alerts when your personal information is at risk, can help detect and stop threats before they escalate.
Stay Ahead of Cybercrime
Cybersecurity is no longer just a business concern, it’s a household necessity. With threats evolving and the Dark Web growing, especially in regions like South Africa, tools like ESET Home Security Ultimate are essential to maintaining your data privacy and peace of mind. Knowledge is power; rather than fearing the unknown, do a little research to understand how you and your family can safely and securely use the internet and reduce your risk by investing in proper online protection with the right security tools. It remains vital to understand local cyber threats in South Africa, so that you can implement the right online security protection.
