My account has been hacked and security question has been changed to russian

No problem @Gatomate , glad to see you're back in action now !

And also, @onelaid113 . I believe there was some while back a leak which allowed hackers to access accounts which only had security question available by being basically capable of bypassing the security question altogether . . Largely affected accounts that have had only a Security Question and nothing else.

The account security question is kinda meant to be a sort of a "last resort" thing you can use in order to be able to recover things on your account if absolutely everything else fails. It is not at all preferred to have on your account *only* the Security Question as honestly, Security Questions are alone not very secure (Reason why Google for example got rid of them altogether), and it is always preferred that you have at least some form of verification available on your account.

All in all though, remember to always make the security question something only you can remember. It doesn't even have to make any sense, if it makes sense to you. Like you can answer to "What street you grew up on ?" something like "Street Fighter" if it makes sense for you.

If you go from the top right and click the little arrow next to your name, and choose EA Account (Or goto Origin, click top left Origin and EA Account and Billing) , and there you click the Security tab, you should always have at least either an e-mail verification or App Authenticator available, preferably also secondary e-mail and Backup Codes. That way nobody can enter your account from any untrusted devices as they need to enter your verification. So even if they would be able to get through your security question they'd have to be able to access either your e-mail or phone and that's a wee bit more difficult to do.

In any case, you have access to your account so you are easily able to contact the support and ask them to change your account details back following the same advice I gave earlier.

Good luck !
