The Dark Side of The Web: Understanding the Dark Web and the Risks It Poses to Organizations

The internet has come a long way since its inception, with an ever-growing number of people relying on it for personal and professional activities. However, with this increased usage comes an increased risk of cybercrime and data theft. And as cybercriminals become more sophisticated, constantly finding new ways to access and exploit sensitive information, organizations must become more vigilant in how they protect their data.

For many organizations, the dark web – a hidden network of websites that are not accessible through standard web browsers – is a growing concern. It is a place where cybercriminals can buy and sell stolen data, hacking tools, and other illegal products and services. This information can be sold to the highest bidder, putting individuals and organizations at risk of financial loss, reputational damage, and identity theft.

In this two-part series, we will take a deeper look at the dark web, the risks it poses and how you can protect your data from getting into the wrong hands.

What is the Dark Web:

The dark web is a part of the internet that is not indexed by traditional search engines and is characterized by its high level of anonymity, allowing users to communicate and transact without leaving a trace. Anonymity on the dark web is often used by cybercriminals for illegal activities such as trading stolen data, buying and selling illegal goods and services, and facilitating various forms of cybercrime, such as hacking and fraud. The high level of anonymity provided by the dark web makes it difficult for law enforcement to trace the origin of criminal activities and identify the individuals behind them.

Accessing the dark web can only be done using specialized tools like The Onion Router (TOR), a free, open-source software and network that was designed to provide users with anonymity and privacy online. TOR networks work by routing internet traffic through a series of servers, or “nodes,” before it reaches its destination. Each node only knows the previous and next node in the chain, making it difficult to trace the source of the traffic. TOR is widely used for a variety of purposes, including accessing the dark web, bypassing censorship and geo-restrictions, and protecting sensitive communications from government surveillance or cyberattacks.

Another important aspect of the dark web is the use of cryptocurrencies, like Bitcoin, as the primary mode of payment. Cryptocurrencies have gained popularity in recent years due to their ability to offer fast, low-cost, and borderless transactions, as well as their use of blockchain technology, which provides a secure and transparent ledger of transactions. However, because cryptocurrencies provide a high level of anonymity and make it difficult for authorities to track transactions, it has become very popular to use by cybercriminals.

Finally, the dark web also uses various other encryption technologies to secure its websites and hide the location of its servers. This includes technologies like SSL/TLS certificates and public-key encryption.

Cybercriminals on the dark web use a combination of tools and technologies to achieve anonymity. For example, they may use the TOR network to route their traffic through multiple servers, making it difficult to trace their location. They also use encryption to secure their communications and protect sensitive information.

In addition, many dark web marketplaces require users to use cryptocurrencies, such as Bitcoin, for transactions. These currencies provide a high level of anonymity and make it difficult for authorities to track financial transactions.

It’s important to note that while the dark web provides a high level of anonymity, it’s not completely secure and can still be monitored by law enforcement agencies. Additionally, many of the activities that take place on the dark web are illegal, so it’s best to avoid visiting it unless you have a legitimate reason to do so.

The Risks Posed by the Dark Web:

The dark web is a haven for cybercriminals, who use it to trade stolen data and carry out malicious activities, such as phishing attacks and ransomware attacks. The anonymity of the dark web makes it a popular platform for these activities, and its encrypted networks provide a high level of security, making it difficult for law enforcement agencies to track and prosecute cybercriminals.

In June 2021, T-Mobile confirmed that it had suffered a data breach that affected the personal information of over 50 million customers. According to reports, the data that was stolen included names, addresses, birthdates, social security numbers, and driver’s license information. Shortly after the breach was disclosed, cybercriminals began advertising the stolen data on underground forums on the dark web, offering it for sale to the highest bidder; over six months later, the data from the T-Mobile breach could still be found online.

This incident is just one of many that highlights the importance of implementing robust cybersecurity measures to prevent data breaches and the need to be prepared for the worst-case scenario. It also demonstrates the devastating consequences that can result when sensitive information is traded on the dark web.

Protection from the Dark Web:

The dark web poses a significant risk to the security of personal and sensitive information. Cybercriminals can use the anonymity and untraceability of the dark web to sell stolen data, engage in illegal activities, and conduct cyberattacks. These risks are further compounded by the increasing sophistication of cybercriminals and their ability to access and exploit vulnerabilities in security systems.

Businesses and organizations have a responsibility to protect the personal information of their customers and employees. It is essential to take proactive measures to protect this data and minimize the risk of it being exposed on the dark web. Protecting against the risks posed by the dark web requires vigilance, education, and a commitment to implementing best practices for cybersecurity.

It’s 2017 – Are You Ready?

If 2016 taught us anything, it’s that we can expect to see an uptick in cybercrime and malicious cyber activity across all industries in 2017 – and an increase in incidents every year thereafter for the foreseeable future.

The Evolution of Cybercrime

The last few years have given cybersecurity professionals a stark glimpse into how the threat landscape is evolving. In earlier days, many attacks were through spam, simple malware, website defacement, phishing, script kiddies, or lone-wolf hackers. Overtime, those attacks have become more sophisticated. We now see an increase in organized (often state-sponsored) hacking syndicates, DDoS attacks carried out on a scale never seen before (such as Mirai botnet), hacktivism and a multitude of cyber warfare tactics; these attacks often lead to serious data breaches and sensitive information theft. The ITRC reports there were 980 data breaches in 2016.

A Technical World

Think back just a year or two. How often did you hear about “internet-connected devices”, aside from your laptop, or the “Internet of Things (IoT)”? Now they’re commonplace in various installations all over the world. We now have “smart” TVs and refrigerators; home automation hardware; wireless security cameras and many more. As we introduce more internet-connected technology into the marketplace, the security of these devices is of the utmost importance.

From a business standpoint, you must take a broader approach to security; unfortunately, there continues to be a disconnect between the security professionals and the C-Suite. Many business owners and CEO’s don’t fully understand the evolving cyberthreat landscape, other than that it has a tendency to put a significant dent into their yearly budgets. But make no mistake about it – failing to properly secure the enterprise can have devastating effects.

What’s Needed for 2017?

Now, let’s get down to it. As we move into 2017, enterprises should take time to evaluate their environment.

  • Where is my data located?
  • What am I trying to protect?
  • Who has access to it?
  • What’s my BYOD (bring your own device) policy?
  • How secure are my endpoints?
  • Is my perimeter strong enough?
  • Is my staff qualified to monitor our network security posture for incidents or indicators of compromise?

Many people may be surprised to hear this, but often the greatest threats aren’t coming from outside of your network in a targeted attack. Rather, it’s your end users who are most likely to put your business assets and data at risk, unknowingly or not. Employees are keeping copies of sensitive data on vulnerable mobile devices and without a significant commitment to securing your infrastructure and data against threats from either side of the firewall, companies will continue to remain at risk due to the more sophisticated and prevalent attacks.

If the trends and evolution of the threat landscape in 2016 are any indication, you can bet that more companies will face interruptions due to ransomware, phishing, data leakage due to negligence and theft or compromised mobile devices due to malware and spyware. Most companies can still expect, at a minimum, to be the targets of automated scans and sweeps from malicious actors attempting to discover services or exploits running on public-facing servers.
