I cover how to create such a wallet further down in this page. Electrum supports two type of watch-only wallets: Deterministic watch-only wallets: These track transactions in a deterministic Electrum wallet i.e. With a new download link, they can continue the attacks seeing as the project team says there are about 50 malicious servers. A watch-only wallet is often used to keep track of transactions on a cold storage electrum wallet. Without taking such steps, the hackers can continue the phishing attack. This would prevent hackers from being able to send error codes that the wallet can decode into a message advising a specific action. We did not publicly disclose this until now, as around the time of the 3.3.2 release, the attacker stopped however, they now started the attack again.Ī more permanent solution would be to eliminate the ability to send customized error messages.

Responding to the attacks, the project team updated the wallet app with a new upgrade that prevents the rendering of rich HTML text.Ĭommenting on this effort, SomberNight said:

If you for whatever reason don't want to use Trezor, cold storage may be a good compromise between the convenience of a hardware wallet and the security of a paper wallet.“A sybil + malware attack is ongoing against Electrum Wallet users,” he cautioned on Twitter. But if you hold a significant amount of bitcoins you don't want to risk getting it stolen. Running a cold storage may seem like an annoyance and quite difficult to set up. The transaction will then be sent to ever Bitcoin node on the network and eventually mined by a miner. Go back to the online watch-only wallet and open Tools -> Load transaction -> From file again.Ī window with the signed transaction detail will show up again.Ĭheck the corresponding values and if it's alright click " Broadcast".

Upon signing the transaction have a look at the field " Transaction ID" which changed from " unknown" to a seemingly random string. You may be prompted to type in the password if your wallet is secured with one (it's recommended). The transaction window will pop up again but this time with an option to sign the transaction. Now go back to your offline computer and go to Tools -> Load transaction -> From file and select the file from the USB stick.

To set up one, you need an (old) computer and a wallet software that is able to import, sign and export transactions.
It can only be accessed physically which makes it very secure. If you care about security and don't feel like buying Trezor, you may want to keep your bitcoins in an offline wallet also known as cold storage.Ĭold storage is a wallet that isn't connected to any network thus it's not vulnerable to online attacks.
