A data breach happens when personal or private information gets exposed, stolen or copied without permission. These security incidents can result from cyber attacks on websites, apps or any database where people’s personal information resides. A data breach can also happen accidentally, like if someone’s login credentials 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。
