Chúng tôi khẳng định một chân lý hiển nhiên rằng mọi người sinh ra đều bình đẳng, rằng tạo hóa đã ban cho họ những quyền tất yếu và bất khả xâm phạm, trong đó có quyền sống, quyền được tự do và mưu cầu hạnh phúc . . . (Lời Mở Đầu Của Tuyên Ngôn Độc Lập Mỹ)
The biggest data breach in history just tripled in size. Yahoo announced Tuesday that every single one of its 3 billion accounts were hacked from a 2013 breach. At the time of the attack, Yahoo claimed 1 billion accounts had been hacked, but after Verizon took over Yahoo, the company investigated further and discovered that all of its approximately 3 billion accounts were affected.
Why you shouldn't delete your Yahoo account
In an earlier version of this story, I suggested you simply delete your Yahoo account and move to Gmail, but it appears doing so may open another workaround for hackers. Yahoo recycles old email addresses, which means that 30 days after your account is deleted, someone could open a new account with your old Yahoo email address and potentially use it to gain access to your other accounts.
After opening an account with the address you vacated, a nefarious individual could impersonate you and fire off password resets requests to get into any of your other online accounts to which you've linked your Yahoo email.
So, instead of deleting your Yahoo account, I suggest you change your password, turn on two-step verification, disconnect all connected services and move to Gmail while leaving your Yahoo account inactive.
Change your password
The first order of business is to change your password. The hack exposed your password so if you do anything, that one thing should be to change your password to a strong password or passphrase that you don't use for any of your other accounts. And if you have repeated your old Yahoo password on any of your other accounts, go ahead and change the password for those accounts, too.
For Yahoo, log into Yahoo Mail, click the gear icon in the upper-right corner and click Account Info. A new tab will open. Click Account securityon the left and then click Change password.
Turn on two-step verification
On the same Account security page where you changed your password, scroll down and click the toggle switch to enable Two-step verification. Enter your phone number and click the Send SMS button and then enter the verification code that Yahoo sent you. Now, someone will need to steal both your password and your phone to get into your account.
Disconnect all connected services
Head back to your Yahoo Mail inbox, click the gear icon in the top-right and click Settings. On the Settings panel, click Accountson the left and you'll see the email accounts, social networks and cloud services connected to your Yahoo account. Click Disconnect on any that are listed as Connected to make it harder for a hacker who gains access to your Yahoo account from getting into your other accounts.
Switch from Yahoo Mail to Gmail
Gmail has a great tool to import data from other email accounts. Go to the inbox and click the gear-icon button in the upper-right corner and click Settings. Next, click Accounts and Import at the top of the page and then click Import mail and contacts. Here, you can enter your Yahoo email address and import your Yahoo data to Gmail. You can choose to import contacts, mail and new mail for the next 30 days.

My email account got hacked and now all of the emails from my inbox, sent, contacts have disappeared!? My account was hacked. Now when I enter Yahoo mail there are not messages in the inbox, the sent box, all my contacts are gone, and all my folders are empty! Please tell me how to restore this problem! 2 TRẢ LỜI : A/ Kittysue Change your password immediately then Fill out a Mail Restore form ASAP http://help.yahoo.com/l/us/yahoo/mail/cl... you only have 48 hours to restore lost mail before it is permanently deleted from Yahoo's server Fill out a Contacts Restore http://help.yahoo.com/l/us/yahoo/contact... Also do all of the following to protect your privacy and identity - From your Inbox click on the Gear icon in the upper right (next to where it says Hi, Yourname) then > Mail Options > POP & Forwarding to make sure your emails are not all being forwarded to the hacker’s address. They will often have your incoming mail forwarded to them - make sure the alternate email address is still yours and you have a security question and answer set - until you get your Contacts back find some other way to reach them - phone, Facebook, twitter, text, etc -- to inform them that your account was hacked. They will soon be getting an email from the scammer claiming to be you needing to borrow money for some emergency and to send it through Western Union or Moneygram - if you used your same username and password for ANY other site, you need to immediately change the passwords on ALL of those accounts. Unfortunately more than 80% of people use the same username and password for everything. Hackers know this and once they know your email login they'll try those same details on Facebook, Paypal, Twitter, Linkedin, Amazon, EBay, every major bank and credit card company, etc to try and hack those accounts as well - if your emails contained ANY financial information (Paypal receipts, online banking statement, credit card bills, et) you need to IMMEDIATELY inform these institutions. You should freeze your bank and credit card accounts and get new account numbers and cards sent to you. Set up a new email address to change your Paypal account. These hackers will go through all of your emails to see if there is anything they can use to steal your money and identity - also consider filing a fraud alert with the credit bureaus if you are in the US -- read the FTC website http://www.consumer.ftc.gov/features/fea...
