Probably your email address and BC password was leaked somewhere for some unknown reason to anybody. Upon having an access to your account, they set the GA that allows them to approve the tipping. As a side --but important-- note, GA does not need to be bound to the same email address [e.g.: your BC account is under
drahmaar@gmail.com, the GA can be set under
not_drahmaar@gmail.com], thus you can't see any account being added to your GA.
With this, I guess everything is now made clear? Or is there other thing that I can help you with to be addressed to my contact?
Yes. Everything is clear, because what you said is possible method how hacker send those tips. But its unlikely. Because if someone has access to my BC email. Than he have access on almost every account of mine. And all of this time I have zero Unauthorized actions on other accounts.
Thats more unbelivable. That someone hacked my email and used it for only BC and send only two tips.
Im so, so curious whats happening here 🤔
EDIT:If you have BC contact with you. Can you ask him to reset my 2FA? Or disable it?
Because now I cant login to my account. When I input user, pass, it requires 2FA app and as I mentioned before. Ive never used 2FA app, so I cant login to my account.
I probably don't have them right now, as the contact "I assign" for your case usually already in their bed by this time, but let me try to reach them anyway and see if they can get the 2FA thing done in the morning.
About the likelihood of hacker being in your account... my contact actually already told me that seclog shows multiple IP accessing your account, though they did not give me the details of the IP for privacy reason. So, I think it's safe to say that there
was someone in your BC account other than you, of whom with 2FA, enabled them to send tips. The reason for tips, I believe was to avoid you noticing it, as it was not recorded in withdrawal or deposit history page, that you'll likely visit the instance you realized there is a discrepancy in the balance from what you have in mind.
And why only two tips? Most likely because you noticed it on the second tips, and we get it disabled before further tips can be made. Suppose you did not realize it, maybe there was, is, and will be more tips made in small batches every time to minimize the chance of you noticing it.
While for the likelihood of the hacker having access to your other accounts if they have your BC email address... did you use the same password for every accounts you have that you use for BC?
