Electroneum wallet holders please read this !!!!

Hey guys i just found out on bitcoin talk the following thread it says that sites can steal your seed while your surfing a webpage . Damn man these hackers they find out ways to f us up 

 

A vulnerability was found in the Electrum wallet software which potentially allows random websites to steal your wallet via JavaScript. The bug presumably also affects altcoin derivatives of Electrum such as Electron Cash. If you don't use Electrum or a derivative, then you are not affected and you can ignore this.

Action steps:

 1. If you are running Electrum, shut it down right this second.
 2. Upgrade to 3.0.4 (making sure to verify the PGP signature).

You don't necessarily need to rush to upgrade. In fact, in cases like this it can be prudent to wait a while just to make sure that everything is settled. The important thing is to not use the old versions. If you have an old version sitting somewhere not being used, then it is harmless as long as you do not forget to upgrade it before using it again later.

If at any point in the past you:

 - Had Electrum open with no wallet passphrase set; and,
 - Had a webpage open

Then it is possible that your wallet is already compromised. Particularly paranoid people might want to send all of the BTC in their old Electrum wallet to a newly-generated Electrum wallet. (Though probably if someone has your wallet, then they already would've stolen all of the BTC in it...)

This was just fixed hours ago. The Electrum developer (ThomasV on the forum, ecdsa on github) will presumably post more detailed info and instructions in the near future.

Update 1: If you had no wallet password set, then theft is trivial. If you had a somewhat-decent wallet password set, then it seems that an attacker could "only" get address/transaction info from your wallet and change your Electrum settings, the latter of which seems to me to have a high chance of being exploitable further. So if you had a wallet password set, you can reduce your panic by a few notches, but you should still treat this very seriously.

1. Thats Electrum wallet, not Electroneum. If you fall for that type of missunderstanding you deserve to be scammed

2. The subject already exist here https://forum.stake.com/topic/4263-critical-electrum-vulnerability/ Thanks to read the rules and avoid to multiply threads about the same thing.

3. I already warned you to stop copy pasting the entire thread from another source.
