A data breach happens when personal or private information gets exposed, stolen or copied without permission. These security incidents can be a result of cyber attacks to websites, apps or any database where people’s personal information resides. A data breach can also happen by accident like if someone’s login credentials accidentally get posted publicly.
个人和隐私信息未经许可被暴露、盗窃、复制，即为发生数据外泄。这些安全事件可能是由对网站、应用或者存放个人信息的数据库的攻击造成的。数据外泄也可能在无意中发生，例如某人不小心把登录凭据泄露出去。
