Personal information from 364,000 people was compromised in a LexisNexis data breach that went undetected for months, highlighting privacy risks. Americans’ personal data is now spread across more digital platforms than ever. From online shopping habits to fitness tracking logs, personal information ends up in hundreds of company databases. While most people worry about social media leaks or email hacks, a far less visible threat comes from data brokers.
I still find it hard to believe that companies like this are allowed to operate with so little legal scrutiny. These firms trade in personal information without our knowledge or consent. What baffles me even more is that they aren’t serious about protecting the one thing that is central to their business model: data.
Just last year, we saw news of a massive data breach at a data broker called National Public Data, which exposed 2.7 billion records. And now another data broker, LexisNexis, a major name in the industry, has reported a significant breach that exposed sensitive information from more than 364,000 people.
LexisNexis filed a notice with the Maine attorney general revealing that a hacker accessed consumer data through a third-party software development platform. The breach happened on Dec. 25, 2024, but the company only discovered it months later. LexisNexis was alerted on April 1, 2025, by an unnamed individual who claimed to have found sensitive files. It remains unclear whether this person was responsible for the breach or merely came across the exposed data.
A spokesperson for LexisNexis confirmed that the hacker gained access to the company’s GitHub account. This is a platform commonly used by developers to store and collaborate on code. Security guidelines repeatedly warn against storing sensitive information in such repositories; however, mistakes such as exposed access tokens and personal data files continue to occur.
The stolen data varies from person to person but includes full names, birthdates, phone numbers, mailing and email addresses, Social Security numbers and driver’s license numbers. LexisNexis has not confirmed whether it received any ransom demand or had further contact with the attacker.
LexisNexis isn’t a household name for most people, but it plays a major role in how personal data is harvested and used behind the scenes. The company pulls information from a wide range of sources, compiling detailed profiles that help other businesses assess risk and detect fraud. Its clients include banks, insurance companies and government agencies.
In 2023, the New York Times reported that several car manufacturers had been sharing driving data with LexisNexis without notifying vehicle owners. That information was then sold to insurance companies, which used it to adjust premiums based on individual driving behavior. The story made one thing clear. LexisNexis has access to a staggering amount of personal detail, even from people who have never willingly engaged with the company.
Law enforcement also uses LexisNexis tools to dig up information on suspects. These systems offer access to phone records, home addresses and other historical data. While such tools might assist in investigations, they also highlight a serious issue. When this much data is in circulation, it becomes a target for misuse.
For many, the LexisNexis breach may be the first time they realize just how much of their data is in circulation. Unlike a social media platform or a bank, there is no clear customer relationship with a data broker, and that makes it harder to demand transparency. This incident should prompt serious discussion around what kind of oversight is necessary in industries that operate in the shadows. A more informed public and stronger regulation may be the only things standing between personal data and permanent exposure.
