Jeff Crume, a Distinguished Engineer at IBM, recently shed light on the pervasive risks associated with the dark web and the importance of safeguarding personal information. In a clear and concise explanation, Crume used the analogy of an iceberg to illustrate the vast, largely inaccessible portion of the internet that constitutes the deep web, with the dark web being its most obscure segment.
Crume highlighted that while only about 5% of the internet is indexed and readily searchable via standard search engines, the remaining 95% is not. This unindexed portion, often referred to as the deep web, contains a vast amount of information, much of which is legitimate and necessary, such as private databases and cloud storage. However, a significant portion of this hidden internet space is dedicated to illicit activities.
Understanding the Dark Web
Crume defined the dark web as the part of the internet that requires specialized software, like the Tor browser, for access. This distinction is crucial because it underscores the intentional effort required to navigate these hidden networks, differentiating them from the surface web that most users interact with daily.

He elaborated on the nature of data found on the dark web, categorizing it into several types, each carrying varying degrees of risk. This includes publicly available information like email addresses, which are often the first step in more targeted attacks. However, the real concern lies with more sensitive data such as passwords, social security numbers, driver’s license details, passport information, credit card numbers, and even corporate intellectual property.
The Risk of Data Exposure
Crume emphasized that the primary vector for personal information ending up on the dark web is through data breaches and phishing attacks. He explained the common scenario where a user receives a fraudulent email, seemingly from a trusted institution like a bank, prompting them to click a link. This link often directs them to a fake login page designed to steal their credentials.
Once a system is compromised, the sensitive data collected can be sold on the dark web. Crume pointed out that while simply having an email address exposed might not be immediately catastrophic, the combination of an email address with a password, or more sensitive PII (Personally Identifiable Information) like Social Security numbers, significantly increases the risk of identity theft and financial fraud.
Mitigating Dark Web Risks
In addressing the question of what individuals and organizations can do to protect themselves, Crume offered several key strategies. He stressed the importance of using strong, unique passwords for every online account, advocating for password managers or passkeys as a more secure alternative to traditional passwords.
Additionally, Crume highlighted the critical role of Multi-Factor Authentication (MFA) or Two-Factor Authentication (2FA). He explained that even if a password is compromised, MFA provides an additional layer of security, requiring a second form of verification, such as a code sent to a phone or a biometric scan, making it much harder for unauthorized individuals to gain access.
Furthermore, Crume recommended actively monitoring credit reports. Services that provide annual credit reports can help individuals detect any unauthorized activity or new accounts opened in their name, which could be an indicator of identity theft. He also mentioned the option of placing a credit freeze, which restricts access to one’s credit file, preventing new credit from being opened without explicit authorization.
Ultimately, Crume’s insights serve as a stark reminder of the digital threats we face and the proactive steps necessary to maintain personal and organizational security in an increasingly interconnected world. Understanding what data is at risk and implementing robust security practices are paramount in navigating the complexities of online safety.
