A laptop (with elctrum) and a PC yes. Problem?

Yes, asking for charity is slightly inappropriate under such circumstances because:

1) This all could be an orchestrated ruse to get some free BTC and apparently small amounts of BTC is a big deal to you

2) You really need to secure you computers first and practice better security in general even if you have 2 devices (there could be cross contamination.

I am not assuming anything but that is kinda how it looks when people overtly ask for charity right after being hacked.

I'm just pissed of because I just spent the last of my cash and lost it almost instantly. fml

Oh and I'm a fairly respected member here. Do you think this some kind of scam?

Yeah, I think you are sincere and is just a very unfortunate experience. You still need to change all your passwords and do 2 reinstalls , and quarantine a lot of your data first until we know exactly how this happened. Hopefully he explains more details soon as he indicated.


Oh and I'm a fairly respected member here. Do you think this some kind of scam?

No, I think you are sincere , but unfortunately many hero accounts are sold off.

A fake electrum server is highly unlikely. Electrum "server" is a bad way to describe it, they are essentially electrum "nodes". There is no trust involved when using an electrum server, they can tell what your IP is and what your Bitcoin addresses are, but they have no ability whatsoever to steal funds. A vulnerability that allowed the server to steal funds in the way the OP described is highly unlikely, as the only task the server does is let the client know about transactions their addresses received, and said information is verified by the client against other nodes.

Based on the blockchain messages I would think that the hacker is likely reading this thread therefore I would suspect it was a more targeted attack as he likely knows the OP had an account here.

It's weird that the bitcoins just arrived in your account and it got transferred in 1 minute. All say that Electrum is safe and this cannot happen unless your PC has been compromised. The transaction note as well is weird and if it's an error from Electrum, you can expect your money back as this might have happened with many other users as well.

There is no need to trust your electrum server much, all they do is give your client transaction data about your addresses and that information is checked against other nodes. They do however have the ability to know your IP address and Bitcoin addresses, so you should only use servers that you think will respect your privacy and use Tor if necessary.

That isn't weird at all. This happens all of the time with hacked brainwallets etc

I am still thinking that it is not a problem of electrum, a 'bug'. Check again your personal computer.

Electrum seed is different than the passphrase of a brainwallet, or am I wrong?

Need to know if my friends are safe, if there is a flaw in electrum
My first question is did you try using any trojan scan tools

http://www.thewindowsclub.com/malware-removal-windows

Try at least to see if there is no nasty stuff on your computer, to make sure its not any of that.

lol non of my friends installed the 2.x they are on 1.9.8

This time with only 0.00003 bitcoin as fee. I'm so curious to see if he will add a blockchain.info tag also to that bitcoin address.

Definitely do that. It seems to be an error from their end and I hope you get your money back.

Also, try to restore your computer to an earlier date when it was working fine to delete any virus (in case it was infected).

So fast? You mean his account was hacked from first? It's quite unlikely and since I have no experience with electrum, it can be a possibility.

Electrum seed is different than the passphrase of a brainwallet, or am I wrong?

It is different, however it can be cracked in the same way, for example if you made up your own seed, one that is easy to remember, people often do things like this and if you do that it likely won't be very random and is vulnerable like a brainwallet. It is also possible that the hacker found the wallet file and noticed it was empty, so he set up his PC to sweep it once funds were transferred to it.

I seriously doubt it is a bug in electrum, nothing in this thread has indicated so, it looks like OP's private keys were compromised somehow.

But it is so complicated to 'find' or crack 12 words (the electrum seed).

Wait, are you quoting your forum message or are you quoting "your" tag?  Grin

Sorry for your loss OP. But I have a feeling this is done by a troll that might give it back eventually.

If your twelve words are all the same word it isn't. Sometimes people "pick" their own seeds that are weaker.

Windows 7 and VMware from encrypted container running Ubuntu
Likely the problem is here, how good is the entropy of this encryption?

Remember Aaron Swartz, a 26 year old computer scientist who died defending the free flow of information.
