It was a bad day.
Clearly.
You put it all down to a trojan and my password being abused,
Not necessarily a trojan, just pointing out that a trojan won't necessarily show up in a virus scan, so the fact that "two deep scans from to up to date virus checkers" come up clean doesn't mean that there isn't a trojan installed.
Of course, it was my laptop and in the end it must be my fault somehow, I agree.
It's never right to blame the victim. I wouldn't say "it must be your fault somehow", but it is good to understand what the possible attack vectors are so effort isn't wasted on things that aren't a threat and so that yourself and others can better protect themselves in the future.
You also don't seem to take the point that the only fraudulent transaction took place under my nose while I was logged in.. ie at the same time. from an IP address on the other side of the world. logged and recorded. There have not been any other attacks, just one, at exactly the same time as I was logged in.
I am aware of that, and the timing is certainly suspect. It is possible that the trojan waited for you to log in and type your password to capture it. It is also possible that someone hacked their way into a remote desktop connection. I suppose it's also possible that the timing was a coincidence. Without more information about how the thief got your password, it is difficult to say why it happened while you were logged in.
How? Exactly? Until I can find some help on that, I can't trust using my blockchain wallet from that laptop. As escrow.mi said, my best option is using a paper wallet until this issue is resolved.
Agreed. I'm very curious about how the thief got your password. If you ever figure it out, please come back and let us know. Such information will make it easier to inform others about how to protect themselves.
sorry to have upset you. Thanks for your help.
Upset me? You've got to try a whole lot harder than that to upset me. Even those who are putting all their effort into upsetting me rarely succeed.
