政府支持的攻击者可能在尝试窃取您的密码

If you received this warning, we believe that government-backed attackers may have tried to compromise your account or computer within approximately the last month. 

​About this warning​

We regularly receive reports from users as well as from our own signaling systems that monitor for suspicious login attempts and other activity. It's likely that you received emails containing harmful attachments, links to malicious software downloads, or links to fake websites that are designed to steal your passwords or other personal information.

For example, attackers have been known to send damaging PDF files, Office documents, or RAR files. 
To protect users going forward, we can't share details about precisely when or how we detected specific attacks. Google’s internal systems have not been compromised. 

The Gmail warning includes personalized guidance to improve your security, based on your current account and browser settings. It will reappear after a short time to help remind you to take the recommended steps toward a more secure account. You can then switch off the warning; if it is shown again after weeks or months, it is because we detected new activity against your account.

Secure your account

Google’s Security Checkup will walk you through a series of steps to limit any damage to your account. To get a step ahead of attackers, take these extra steps to better secure your account and computer:
  • 加入高级保护计划。这样可以防止攻击者通过常用的方式盗用您的帐号,保护您的电子邮件、文档、通讯录和其他个人信息不被窃取。
  • 始终使用最新版软件。其中包括互联网浏览器、操作系统、插件和文档编辑器。您可以考虑改用 Chrome 浏览器。这款浏览器会自动更新安全功能,从而降低运行过期软件的风险。此外,Chrome 浏览器还能安全地打开 PDF 文档。
  • 在 Gmail 中启用两步验证启用此功能后,系统会向您的手机发送第二个密码,让安全性又多一重保障。此功能已证实可成功地抵御某些攻击。
  • 安装 Google 身份验证器如果您已启用两步验证,我们强烈建议您安装身份验证器应用,以便在没有互联网连接或移动数据服务时接收验证码。
  • 在 Gmail 中设置安全密钥。这些物理密钥适用于 USB 插槽,还能通过蓝牙或 NFC 运行。它们能提供最有力的两步验证形式,可保护您的帐号不受黑客攻击。基本型号的售价在 20 美元以下。除 Gmail 外,还适用于更多其他网站。
  • 在 Chrome 中安装密码防护警示这是一款免费的开放源代码 Chrome 扩展程序。如果您重复使用密码或在假冒的登录页面输入密码,此扩展程序会立即向您发出警示。
  • 移除多余的弹出式窗口和其他恶意软件。如果您一直看到弹出式窗口、不认识的广告或者您并未设置的主页,您的计算机上可能存在被称为“恶意软件”的有害程序。要移除恶意软件并保护您的浏览器,请按照这些反恶意软件提示操作。
