Massive Data Leak at MC2 Exposes Private Information of Over 100 Million Americans

An exposed database at background check company MC2 Data has reportedly leaked the private information of over 100 million Americans, raising serious concerns about privacy and safety. The database, containing 2.2TB of data, was left unprotected and easily accessible on the internet, exposing sensitive data such as names, emails, IP addresses, encrypted passwords, and more.

Cybernews researchers discovered the massive data leak, which affected at least 100 million individuals, including 2,319,873 MC2 Data subscribers. This breach follows a similar incident earlier this year at National Public Data, where the data of nearly 3 billion people was leaked.

Background check services are crucial for verifying individuals’ backgrounds and assessing risks for employers, landlords, and others. However, when such services fail to protect sensitive data, they face regulatory consequences, lawsuits, and reputational damage.

Aras Nazarovas, a cybersecurity researcher, highlighted the risks associated with background-checking services, stating that cybercriminals could exploit leaked data to target victims more effectively. The discovery of the MC2 database in August underscores the importance of securing sensitive information to prevent unauthorized access.

While it remains unclear if the leaked data fell into the hands of cybercriminals, the database was eventually secured after Cybernews notified MC2 Data. This incident emphasizes the need for robust security measures and vulnerability scanning services to prevent future data breaches.
