Personal data has become one of the most valuable assets in the digital age, driving a wide range of business models across industries. In recent years, however, this data has moved beyond its conventional uses—like targeted advertising and personalized services—and has found its way into the hands of cybercriminals. This has given rise to a new underground market where stolen personal information is bought and sold, fueling a wave of sophisticated scams, identity theft, and extortion. The growth of this data-driven economy has introduced a variety of risks, but also an increasingly complex landscape where data and its exploitation have become highly commodified.
Data as a Treasure Trove
The surge in data breaches over the last decade has resulted in an overwhelming amount of personal information flooding the dark web, which has become a primary platform for cybercriminals seeking to profit from stolen data. The dark web, an anonymous part of the internet that can only be accessed using specialized tools such as Tor, offers a marketplace for illicit transactions, including the sale of personal information. Here, information such as names, addresses, email accounts, social security numbers (SSNs), and even medical records are traded among those willing to pay. With tools like Tor and VPNs masking the identities of both sellers and buyers, this market thrives in a relatively secure, private environment where cybercriminals can operate without fear of detection.
The prices for these data sets vary depending on their quality and completeness. For example, full identity kits—which provide everything needed to impersonate a person—can range from a few dollars to thousands. Financial information, such as credit card numbers or banking credentials, typically commands lower prices but remains highly valuable for conducting fraud. Medical records, which include sensitive data like prescriptions and insurance details, can be sold for hundreds of dollars. These transactions, though illegal, operate similarly to legitimate markets, with data brokers acting as intermediaries who facilitate deals between sellers and buyers.
The Surge of Data Breaches
Over the last decade, more than 15 billion records have been exposed in data breaches, compromising sensitive personal information. These breaches, affecting individuals around the world, have occurred across various sectors. High-profile corporate breaches, like those of Target, Equifax, and T-Mobile, have led to the release of vast quantities of customer data, making it widely available on the dark web. In addition to corporate breaches, government databases have also been compromised, resulting in the exposure of employees' personal data and credentials. Health and medical records have likewise become a prime target, as breaches in hospitals, clinics, and insurance providers have revealed detailed medical histories, making these records highly valuable on the underground market.
Furthermore, social media platforms like Facebook, LinkedIn, and Instagram, which store vast amounts of personal data, have also been frequent targets of cybercriminals. As more individuals share personal information on these platforms, they unwittingly increase their exposure to theft and misuse. The combination of high-profile data breaches and the widespread sharing of personal data on social media has led to a significant rise in the sale of personal information on the dark web, creating a thriving, albeit illicit, market for cybercriminals.
How Stolen Data Fuels Modern Scams
The availability of personal data on the dark web has given rise to a new generation of scams. These scams have evolved from simple, generalized fraud attempts into highly targeted attacks that make use of specific details about their victims. This transformation is largely due to the wealth of personal information that is now available for purchase. In the past, scams were often generic, such as phishing emails from unidentifiable sources. Today, cybercriminals are able to launch more sophisticated, personalized scams that leverage detailed knowledge about their victims.
Phishing, for example, remains a popular tactic. Attackers send fraudulent emails, SMS messages, or phone calls that appear to come from legitimate sources, such as banks or government agencies. These communications often include personal details about the victim to make the scam appear more credible. Spear-phishing, a more targeted form of phishing, takes things a step further by impersonating people or organizations that the victim knows and interacts with regularly. In more extreme cases, criminals may use business email compromise (BEC) tactics, gaining access to corporate email accounts to authorize fraudulent transactions, often in the millions of dollars.
The data obtained from these scams is not just used for short-term financial gain. It has also facilitated the rise of more complex fraud schemes, such as identity theft. Criminals can create synthetic identities by combining bits of personal data, such as a fake birthdate or social security number (SSN), to open bank accounts, take out loans, or apply for credit cards. Full identity kits purchased from dark web marketplaces can be used to impersonate victims in order to commit a wide range of financial fraud.
Another form of financial fraud facilitated by stolen data is tax refund fraud. Using compromised SSNs, criminals can file false tax returns and claim refunds in the victim’s name. This has become a widespread issue, particularly in regions like the United States, where large-scale data breaches have exposed millions of personal records.
SIM-swapping, a type of fraud in which criminals use stolen personal data to convince mobile providers to switch a victim’s phone number to a new SIM card, is also on the rise. This allows attackers to bypass two-factor authentication (2FA) and gain access to bank accounts, email accounts, and other sensitive online platforms.
Other Types of Scams
The dark web economy has birthed several new types of scams that are becoming increasingly common. Romance scams, for example, are facilitated by information gathered from social media or dating sites. Criminals use this data to create believable personas and manipulate victims into romantic relationships. Once trust is established, they exploit the relationship to convince victims to send money, often with emotional manipulation.
Another particularly insidious form of crime involves sextortion and blackmail. Criminals use personal information obtained from adult and dating websites to threaten victims with the release of compromising material—such as explicit photos or conversations—unless a ransom is paid. In some cases, criminals have also begun using deepfake technology to create realistic fake videos or audio clips, adding a new layer of threat to this form of blackmail.
Swatting, a dangerous practice in which criminals use stolen personal information to make false emergency calls to police, is another alarming consequence of personal data being sold and used maliciously. This has led to SWAT teams being sent to innocent people's homes, often with disastrous consequences.
The Global Trend of Scams
The impact of data breaches and scams is felt globally, with the frequency and sophistication of these incidents increasing every year. The digital landscape is vast, and as more individuals use online services, the exposure to risks grows. This has led to a rise in scams worldwide, affecting individuals in both well-established and smaller countries, where cybersecurity infrastructure may not be as robust.
In Europe, the General Data Protection Regulation (GDPR) was introduced to protect the personal data of EU citizens. While this regulation has certainly helped raise awareness around data privacy, many organizations still fail to implement proper security measures, leading to widespread breaches. One of the most common scams targeting Europeans is government impersonation fraud, where fake notifications about unpaid fines or tax liabilities are sent to victims, who then fall prey to phishing attempts or financial scams.
In the United States, high-profile data breaches such as those involving Equifax and T-Mobile have exposed millions of Americans to the risk of identity theft and financial fraud. SIM-swapping attacks have surged in recent years, further contributing to the increase in scams and fraud.
The Growing Need for Vigilance
The darknet has evolved into a marketplace where personal information is exchanged for financial gain, and with the increasing frequency of data breaches, the risks to individuals are becoming more pronounced. However, the presence of this market and the exploitation of personal data also highlight the need for greater awareness and vigilance. By taking proactive steps to secure their data and by ensuring that they stay informed about potential scams, individuals can better protect themselves from becoming victims of these increasingly sophisticated criminal operations. Governments, corporations, and consumers must all work together to foster a safer, more secure digital environment.
