黑客模仿我客户域名发进来诈骗邮件，公司损失数十万美金？
1.邮箱定期修改密码，并且每个人的密码都不要相同，现在很多公司偷懒也为了方便管理，所有账户都是统一密码并且长期不修改，这种非常危险
2.信任客户的邮箱加入白名单，还可以限定邮箱IP
3.开启邮箱垃圾邮件报告，会自动拦截垃圾邮件
4.就靠人都看一眼邮箱域名了，域名作为唯一标识，还是会有细微区别
有人给我发英文邮件向我勒索比特币 我要怎么办
我刚刚收到，但是是在2月26日，我现在都29日了，它提醒我说只有两天，呵呵，我就是一个纯洁善良的网友，现在骗子都那么丧心病狂了吗？再说我这个是Mac系统，不是说不容易被黑客攻吗？内容如下：_Hello!

Thís means that Í can see everythíng on yoür screen, türn on the camera and mícrophone, büt yoü do not know aboüt ít.
Í also have access to all yoür contacts and all yoür correspondence.
Why yoür antívírüs díd not detect malware?

收到一份黑客勒索邮件，怎么办？
你要是不在意就不用理会，你要是觉得不安，就去当地公安局的官网上报网警。
黑客入侵了我的邮箱，然后用我的邮箱发给了我自己一封勒索邮件。求助！！！！！
其实你不用担心，你的邮箱没有被入侵，你的信息没被他掌握，你的电脑也没有被他种木马病毒，他只是伪造了发件人，可以让你收到的邮件显示的发件人是任何地址，甚至是你自己的邮箱地址。不用理他，当做垃圾邮件吧。
持续收到英文敲诈邮件怎么办
你好，收到类似的邮件的话，直接将该发件人拉入黑名单，另外将该邮件举报，这样你就不会收到这样的邮件了，另外如果你的邮箱可以，那你可以设置一个收信规则，设置敏感词，然后不接受这类邮件，可以帮你避免该类邮件，千万不要点击上面任何链接，避免被盗号，希望可以帮助到你！
电脑被黑客反复发送勒索邮件怎么办？
1修改全部的密码，保证安全（建议使用其他电脑或手机，平板这些登陆修改，不要使用这个电脑修改
2考虑一下更换系统也可以说是重新安装系统
3安装系统后必要的安全软件。
这些方法使用过后应该可以解除被盗的可能（就算已经被盗，只要修改密码就可以，一定要比对方快一点，否则有些账号被修改了手机号码等等就麻烦了。重新需要联系客服等等）
