#ELECTRUM SEED SOFTWARE#
My working hypothesis: there ought to be another wallet software that existed around 2013 that used Electrum's "old" word list and generated 15 words by default. This method produces 15 words that Electrum GUI does recognize as 12 + 3 (extended), but leads to empty wallet. For example you can create a multisig wallet like this. It is feature rich, trusted open source wallet and even supports integration of hardware wallets such as Ledger and Trezor. I cloned Electrum repository from github and tried converting mnemonic to hex seed using the old list, then converting it back to mnemonic using the "new" word list. Electrum is the most popular desktop wallet that is simple, light weight and has been around for many years.
I considered the possibility that this mnemonic was extended with custom words, but it looks like custom words in Electrum work only with the "new" word list. This Electrum wallet guide is based on Electrum 3.1.0, and this specific.
It doesnt really matter that much since the default number of mnemoric words is more than safe. The extended seed option basically just increases the difficulty of anyone bruteforcing your seed. That version is not safe at all, please shut it down.
#ELECTRUM SEED UPGRADE#
But the number 15 is puzzling, since no version of Electrum ever produced 15 words by default, as far as I know. Search around for a Tails upgrade or just upgrade your Electrum. After that, you have to copy your wallet generation seed. I suspect the passphrase was used to encrypt the wallet, and is probably irrelevant here, since the wallet file itself is lost.Īll words are found in the "old" Electrum list. Electrum Wallet is one of the three wallet versions that are available to download on the Firo. All that is known is a passprase, and 15 words. First download Electrum, try to get a version closest to the one you were using. Once compromised, the hackers can use these keys to empty crypto wallets of unsuspecting users that downloaded the wrong app.The wallet was created around Feb 2013, using unknown wallet software. The seed keys are cryptographic keys that owners use to access different wallets via the app. In a further attempt to deceive users into downloading the malware cybercriminals registered the domain to copy the original .ĭevelopers have exposed a line of code from the fake wallet that appears to take the user’s seed key and upload it to the spurious domain. It was obvious for a while that the duplicate wallet was malicious as it used the branding of the company without permission.
#ELECTRUM SEED HOW TO#
Fake Bitcoin Wallet Swipes Seed KeysĪccording to reports the team behind the original wallet posted a document on Github explaining how to get rid of the impostor. The way that Electrum used to do the derivation, that is still used by Monero and others, is by having a wordlist with a fixed length of 1626 words.
#ELECTRUM SEED PRO#
The dubious doppelganger called Electrum Pro appeared online in March and has been flagged as malware since. Also we’ll explain why it is not recommended nor it is secure to import a mnemonic seed into hardware wallets from software wallets.
Similarly we’ll see how to import electrum’s 12 word seed into Trezor and Ledger. The wallet will then scan the blockchain and check the balances of each address to calculate the total balance associated with the seed phrase. Researchers at popular Bitcoin wallet app Electrum have exposed a malicious copycat that has been designed to steal seed keys. Here in this guide we’ll explain how to import Ledger and Trezor mnemonic seed phrases into Electrum wallet. Importing the seed phrase into Electrum or a similar software wallet, will effectively recover all the addresses and private keys associated with that seed phrase.
