When Electrum wallets are synchronized with malicious servers, they are instructed to "update" clients provided by hackers, resulting in the loss of assets contained in older versions. Previously, in December 2018, Electrum.
Electrum Wallet is one of the most popular Bitcoin wallets and has been around for several years. However, Electrum wallet users often rely on Electrum servers, which presents some security and privacy trade-offs. If you use electrum personal servers, Electrum wallet users can connect locally to their own private servers, enjoying the convenience of Electrum without any trade-offs.
Data redundancy tends to reduce write efficiency because synchronizing data consumes additional resources.
Electrum developers are now warning about many other projects that try to clone popular wallets after the december announcement of a phishing attack. On January 10th they warned on Twitter that they were carrying out a sustained phishing attack on Electrum users, with rogue servers demanding that they install Bitcoin to steal malware. We released version 3.3.2, which mitigates attacks.
electrum stuck synchronizing out of date
Electrum is another popular Bitcoin wallet that has been around for nearly a decade. Electrum Bitcoin Wallet has been available for all devices since 2011 and was one of the most widely used wallet applications before other alternatives emerged. There are still a lot of people who are still swearing at the Electrum wallet.
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).

Lesson 1: Third-party Electrum servers can link your two transactions together. This can be avoided by running your own Electrum server, supported by your own full node.
The electrum and Electrum-LTC versions below 3.3.3 are vulnerable to phishing attacks in which a malicious server displays a message asking the user to download the fake Electrum. To prevent user exposure, versions older than 3.3 can no longer connect to public servers and must be upgraded. Do not download software updates from sources other than electrum.org and electrum-ltc.org.
Is NASDAQ's LINQ out of date?
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.
The fact that not many people know is that Esplora is bundled with a based and optimized Electrum server. This Electrum server is derived from Electrs and is now maintained separately by the Blockstream engineering team. Over the past two years, Esplora has become one of the fastest and most scalable Electrum server solutions available for Bitcoin due to continuous updates and performance optimization. Esplora is also the only Electrum server that supports liquid networks.
This is similar to the price movement in early June. It is currently stuck between the diagonal resistance and the 89 EMA, which is a reliable indicator to date.
