I'm not sure how this could have happened to you? Don't you have two stage log in? I have that enabled so every time I log in I need a cell phone signal. It's the safest way. It sounds like you have some kind of malware that stole your credentials from your PC.
Even if my PC does have a malware which im unaware of, I should still have received F2A on my phone shouldnt I have? also if my phone number was stollen and transfered to the hacker, then howcome I was still getting sms messages from coinbase telling me they paused the transactions (what was left of them) as the theft was taking place?
Also with the email asking me to varify that another device is trying to login that coinbase has not seen before or for some time.
Heres a copy of the email:
Coinbase
New device access
A device or location we haven't seen before, or for some time, is requesting access to your account:
Location: United Kingdom
IP Address: 195.147.132.40
Browser: Chrome (Windows)
If you approve of this action, please click the link below to authorize this device.
Note that you need to access this email with the same device that you are confirming.So because it also said that i need to access this email with the same device that you are confirming, I thought that only I can access it and no one else.
Any ideas how this could have happened? Coinbase still have not replied back and my account is still disabled.
