The dangers of the dark web are not as hidden as you might think.

The dark web is presented as a hidden marketplace where sensitive information, private data, and corporate vulnerabilities are traded anonymously. This area of the internet has emerged as a critical point due to the illicit activities that occur within it, many of which go unnoticed by most users. Recent incidents of high-profile data leaks highlight the urgency of the problem. In May 2024, data from over 500 million Ticketmaster customers was leaked on a dark web forum. Previously, in April, AT&T faced a similar setback with the exposure of data from 73 million users, including social security numbers and access codes. Even LinkedIn was affected in 2021, when data from 700 million users was put up for sale, representing more than 90% of its user base.

Although this part of the internet represents only a small fraction, the dark web continues to grow as a threat to companies globally. In these encrypted spaces, corporate data flows, from stolen credentials to trade secrets, which can lead to potential crises for any entity handling valuable information. It is essential for organizations to stay informed and prepared against these threats.

The dark web is a hidden sector of the internet that most people do not access. Unlike regular websites, access to this format requires specialized tools like the Tor browser, and it uses .onion domains that are neither visible nor indexed by search engines. Originally created by the United States Department of Defense to secure communications, the dark web has become a largely unregulated space where anonymity reigns.

Despite the dark web representing less than 0.01% of the entire web, it has gained a notorious reputation for illegal activities. Under its cloak of encryption, users find markets where drugs, stolen data, counterfeit documents, and even weapons are exchanged. While some access the dark web for legitimate reasons, such as protecting their privacy, the risk is considerable as it can expose users to scams, malware, and legal issues if they enter restricted areas.

Government agencies are making efforts to monitor the dark web and counter these threats, but it remains a space where order has limited reach. For most, the wisest course of action is to avoid this environment, which recalls the dark side of the internet.

For companies to protect themselves in this delicate environment, it is essential to understand that their attack surface is broader than previously thought. It should be accepted that certain organizational data may already be circulating on the dark web, and action must be taken:

1. Monitor leaked credentials: Conduct regular checks for exposed username and password combinations.
2. Look for accounts and access for sale: Scan dark web markets to identify compromised accounts linked to the organization.
3. Monitor IP-based leaks: Search for information related to company IPs that may have been leaked.
4. Identify data from previous breaches: Recognize sensitive information that has been exposed as a result of prior attacks.

Mapping this information within the attack surface graph is crucial to prioritize remediation efforts. Having context is essential to know not only where the exposed information is located but also which areas require immediate attention. Protecting the company from dark web threats requires not only the right technology but also a proactive approach that considers constant monitoring and preparedness.

Recognizing that even a small leak can have devastating consequences is vital for strengthening the organization’s defenses. Training teams and incorporating this awareness into the security strategy ensures that everyone is ready to respond quickly and effectively.
