About Data Breach

As organizations continue expanding digital infrastructure, storing vast volumes of sensitive data, and adopting cloud platforms, unauthorized data exposure has become one of the most common, costly, and disruptive cybersecurity incidents. To gain a better understanding of how and why breaches occur, researchers, journalists, and cybersecurity professionals frequently reference data breach statistics. This page combines verified data breach incidence rates, cost, and impact metrics from leading research firms, cybersecurity industry reports, and threat intelligence datasets.

The majority of unauthorized data exposure incidents are caused by hacking, or a malicious attack that involves exploiting weaknesses in your systems and/or network, typically gaining access with stolen credentials. Hackers will typically look for vulnerabilities in your employees, system, or network and use those to pierce your defenses, access data, and steal information.

Some of the largest data breaches involve billions of records. These breaches have huge short- and long-term consequences for the organizations involved.

Cybercriminals have two main motives for committing data breaches: to gain and/or harm. Gaining can take many forms, including selling or trading personal information for financial compensation. Harm can be inflicted on a company or individual through the loss of customer trust, brand reputation damage, and operational disruption.

The most commonly targeted industries include healthcare providers, financial services companies, retail stores, and manufacturing companies, but attacks also target government agencies. Government agencies manage national identity, citizen records, tax information, law enforcement databases, and critical infrastructure data that are valuable for espionage, fraud, and geopolitical operations.
