Hacked

my BiS lvl 80 DK named Necrotique just got hack

i have my two factor authenticator activated and there is no notification if some1 was login to my account. and now i cant login to my account anymore

the last time i logon was 2 days ago and it still okay and also the hacker allready change the name

is there any way i can retrieve back my account ?

If you had 2fa on, did they hack your email also? If so, then secure your email

I guess, mailing [email protected] and telling them about it

They didnt hack my email thats the confusing part

i allready check my email and everything seems fine but there is no notification or anything when some1 log to my account
