Oh, and when you want to use the money that's in your paper wallet now or for years to come, don't forget your current BTC and BTU! (Electrum and Blockchain)

Electrum is a world-renowned Bitcoin light wallet with a long history of multi-signature support and a very broad user base, many of which like to use Electrum as a cold wallet or multi-sign wallet for Bitcoin or even USDT (Omni). Based on this usage scenario, Electrum is used less frequently on the user's computer. The current version of Electrum is 3.3.8, and previous versions of 3.3.4 are known to have "message defects" that allow an attacker to send an "update prompt" through a malicious ElectrumX server. This "update tip" is very confusing to the user, and if you follow the prompt to download the so-called new version of Electrum, you may be tricked. According to user feedback, because of this attack, stolen bitcoins are in the four digits or more. This captured currency theft attack is not stealing the private key (electrum's private key is generally stored with two-factor encryption), but replaces the transfer destination address when the user initiates the transfer. Here we remind users that when transferring money, special attention needs to be paid to whether the destination address has been replaced, which is a very popular method of currency theft recently. It is also recommended that users use hardware wallets such as Ledger, and if you pair it with Electrum, although the private key does not have any security issues, you should also be alert to the replacement of the destination address.

Electrum is a popular software wallet that works by connecting to a dedicated server. These servers receive a hash of the Bitcoin address in the wallet and reply with transaction information. Electrum wallets are fast and have few resources, but by default, it connects to these servers and can easily monitor users. In addition to Electrum, some other software uses public Electrum servers. By 2019, it is a faster and better alternative to BIP37.

There are several Litecoin wallets to choose from! Such a good wallet - Electrum Litecoin wallet! View exclusive reviews on Electrum.

Most of the wallets we use frequently are in this category, including Bitcoin Electrum, imtoken. The private key of this type of wallet is also the user's own, and is easy to use.

Users of Bitcoin wallet Electrum are currently facing a phishing attack, according to the Devi Security Lab. Hackers broadcast messages to electrum clients through a malicious server, prompting the user to update to v4.0.0, and if the user follows the prompt to install the backdoor-carrying client, the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs worth approximately $11.6 million had been stolen from phishing attacks that forged Electrum upgrade alerts. Devi Security Labs hereby suggests that versions of Electrum below 3.3.4 are vulnerable to such phishing attacks, and users using Electrum Wallet are requested to update to the latest version of Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released v4.0.0, and do not use the link in the prompt message to avoid asset losses.

Users of Bitcoin wallet Electrum are currently facing phishing attacks, according to the Devi Security Lab. Hackers broadcast messages to electrum clients through a malicious server, prompting the user to update to v4.0.0, and if the user is prompted to install this backdoor-carrying client, the private key is stolen and all digital assets are stolen. At the time of writing, at least 1,450 BTCs (stolen by one user, antimalware firm Malwarebytes and Electrum) had been stolen in phishing attacks that faked Electrum upgrade tips, with a total value of approximately $11.6 million. It is worth mentioning that electrums below version 3.3.4 are vulnerable to such phishing attacks, and users of Electrum wallets are requested to update to the latest version of Electrum3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the links in the prompts to avoid asset losses.

Johnwick.io found that hackers launched a denial-of-service (DoS) attack on a well-known wallet, Electrum server. Hackers used a botnet of more than 140,000 computers to attack Electrum's nodes and simultaneously deployed malicious nodes. When a user connects to these malicious nodes and sends a transaction using an older version of Electrum, the user is prompted to update the Backdoor Client. If the user installs the client as prompted, the private key is stolen and all digital assets are lost. Millions of dollars of digital currency have been stolen, according to Electrum officials. Devi Security Labs recommends that users of Electrum Wallet update to the latest version of the client via the official website and never use the link in the prompt message.

To do this, it calls many APIs, such as WNetOpenEnumW(), WNetEnum ResourceSource W(), NetShareEnum(), OpenSCManager W,W,W, WNetAddConnection 2W, and so on.

Bitcoin wallet Electrum official Twitter announced that the next version of Electrum will support Lightning online payments. Its lightning node implementation has been consolidated into the main branch of Electrum. Electrum also confirmed that the wallet will adopt a new implementation of in-house development written using Python.

Well-known Bitcoin wallet Electrum "update phishing" currency theft continues.

It is reported that malicious websites (electrumsecure) fake Electrum website phishing attacks, to guide users to download and use the wallet, in order to steal the user's private key and other sensitive data.

However, after electrum officials said in early 19th that some security mechanisms should be put in place to prevent this "update phishing", many users of Electrum are still in the old version.

If you pay online using cryptocurrencies, Electrum is ideal for keeping a small amount of currency ready for use.
