In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum wallet client, forcing an "update prompt" to pop up during a user's currency transfer operation, inducing users to update and download malware to carry out a currency theft attack, according to Slow Fog. Although electrum officials said in early 2019 that some security mechanisms would be in place to prevent this "update phishing", many users of Electrum are still in the old version (less than 3.3.4) and the old version is still under threat. However, we do not rule out a similar threat to the new version.

Bitcoin desktop wallet client Electrum has released a 4.0 beta version, adding several important updates, including support for the Lightning network, nearly a year after the previous version of Electrum, 3.3.8 (last July). In the 4.0 beta version, Electrum mainly added features such as PSBT (partially signed Bitcoin transactions), Lightning Network, watchtowers (暸 watchtowers) and Submarineswaps (subliminal switching).

Electrum DASH "PrivateSend" is on TestNet.

Wallets that are widely used include Bitcoin Electrum, Ether Wallet, imtoken and Jaxx. The Privat Key for this type of wallet is in the user's own hands, more secure and easy to use. The limitation is that after the transaction signature is completed, the transaction is broadcast out or depends on the central node server, when the volume of business is large, the server performance overload, may cause the transaction can not be successfully sent.

Last week, news of a failure of Intel's computer chips, which have remained undetected for years, shook the entire technology industry. It's a story similar to the vulnerability of electrum wallets, which some reports say have been around for more than two years. Tavis Ormandy, Google's vulnerability researcher, claims to have discovered the vulnerability, even though it was flagged last year. Within hours of Electrum being identified as a vulnerability, Electrum rushed to come up with a patch to fix it.

Similarly, lnd v0.10-beta supports the partially signed Bitcoin transaction feature, which enables users to fund their new Lightning channel directly from their hardware wallet or external wallets, such as Electrum and other wallets that support the PSBT (partially signed Bitcoin transaction) format.

Users of Bitcoin wallet Electrum are facing phishing attacks, according to Johnwick.io. 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 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.

Lightning support in Electrum has been around for a long time. Thomas Voegtlin, the founder of Electrum, first told CoinDesk last summer that Lightning would take it to the next version.

Google researcher Tavis Ormandy discovered the Bitcoin wallet Electrum.

In December 2018, Slow Fog first discovered and alerted an attacker to a messaging flaw using the Electrum wallet client to force an update prompt to pop up when a user transfers money, inducing users to update and download malware to carry out a currency theft attack. Recently, slow fog technology anti-money laundering (AML) system through continuous tracking found that one of the attackers wallet address bc1qc... p2kny has stolen more than 30 BTCs for six months and has been active recently. Slow Fog alerts Electrum users to update prompts, the new version of Electrum in this update prompt is likely to be false, if installed, please promptly transfer Bitcoin out in another security environment. At the same time, slow fog called on the vast number of cryptocurrencies exchanges, wallets and other platforms of the AML wind control system black and monitor such as the above Bitcoin address. This update tip is a phishing attack by an attacker who exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and according to incomplete statistics, hundreds of bitcoins have been stolen in this phishing attack over the past year or so. Although in early 2019 Electrum officials have said they want to adopt some security mechanisms to prevent this kind of update fishing, such as: 1. Patch Electrum client does not display rich text, does not allow arbitrary messages, only strict messages; Patch ElectrumX server implementation detects Sybil Attack (i.e. witch attacks, malicious servers that send phishing messages) and no longer broadcasts them to clients; Implement blacklisting logic to alert malicious servers outside the Electrum client view; Promote social networking sites, websites, and all forms of communication that exist with users, who should always run the latest version and always only install from official sources (electrum.org), access through security protocols (https), and verify GPG signatures in advance. However, many users of Electrum are still in the old version (less than 3.3.4), the old version is still under threat, but slow fog does not rule out that the new version will have a similar threat.

This update prompt is not an official act of Electrum, but a phishing attack by an attacker that exploits a message flaw on the Electrum client and the ElectrumX server, which requires the attacker to deploy the malicious ElectrumX server in advance, and the malicious server is localized by the user's Electrum client (because the Electrum client is a light wallet and the user needs the ElectrumX server to broadcast the transaction). At the time of the madness, malicious ElectrumX servers accounted for as many as 71% of the total, and according to incomplete statistics, hundreds of bitcoins have been stolen in this phishing attack over the past year or so.

Ormandy claims to have discovered the vulnerability, even though it was flagged last year. Within hours of Ormandy pointing out the vulnerability, Electrum came up with a patch to fix it.
