Summary: According to a Reddit post on March 26, youTube, the video-sharing platform, allegedly miscast malicious ads about Electrum, a Bitcoin (BTC) wallet. In a Reddit post, a user named mrsxeplatypus alerts the public about malware and describes how scam ads work: malicious ads masquerade as an Electrum ad, even showing positive links.
In addition, small partners who have used Electrum wallets should be aware that with Thecret phrase generated by Electrum, we can recover bitcoin keys on any browser using the Bitcoin Wallet web tool. And Electrum is so secure that there is no evidence that the distributed attack prevention system designed by Dark Wallet will be due to Electrum.
Digital wallet developer Electrum has released an emergency patch saying it found a vulnerability that could lead any website hosting Electrum to steal a user's digital currency, exposing passwords to the JOHNSONRPC interface and ingelling hackers full control of the wallet. Earlier, Electrum released the first patch, but it didn't seem to solve the problem, and they released a second update urgently Sunday night local time.
Almost no Bitcoin wallet can be said to have been involved since the beginning. Electrum announced in 2011 that it had changed course during the downturn in the Bitcoin market. It is now estimated that about 10% of all Bitcoin transactions are reflected in Electrum.
The main reason for the Trezor vulnerability is that it does not have built-in multi-signature functionality, so its multi-signature implementation is to support Electrum extensions. This leads to an attack on Electrum, and Trezor is affected.

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.
This isn't the first time electrum has appeared in a fake version. In December, nearly $1 million of BTC was stolen when hackers developed a fake encrypted wallet, Electrum. 1 this year.
Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Devi Security Lab. Hackers broadcast messages to the Electrum client through a malicious server, prompting the user to update to v4.0.0, and if the user follows the prompt 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 about $11.6 million had been stolen from phishing attacks that faked Electrum upgrade tips. DeViable 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 Electrum 3.3.8 via the official website (electrum.org), which has not yet been officially released, and do not use the link in the prompt to avoid asset losses.

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.
