A data breach is a security incident in which sensitive, protected, or confidential information is accessed, copied, transmitted, or exposed by an unauthorized party, whether or not that access was deliberately malicious.

While breaches are often associated with hackers deliberately exploiting a technical vulnerability, a significant share of real-world breaches actually stem from simpler causes, including weak or reused passwords, misconfigured cloud storage left publicly accessible, and employees falling for phishing attempts.

Unauthorized Access, Not Always Malicious Intent

Common Causes Beyond Hacking

The scale and sensitivity of exposed data vary enormously, from a single leaked email list to breaches exposing millions of users' passwords, financial details, or medical records, which is part of why breach severity is assessed case by case.

After a breach is discovered, organizations typically face legal obligations to notify affected individuals and regulators within a set timeframe, alongside the practical work of closing the security gap and helping affected users protect themselves, such as by resetting exposed passwords.
