Connect the client socket we just created to the socket on the other side of the server. The function used is connect, which requires three parameters.
Jeff Moss, the subject of DEF CON CHINA 1.0, says technology today brings convenience and unavoidable red tape. AND DEF CON.
Attackers reportedly implemented a compromised version of their Own Electrum server hosting to enable hacking. When users synchronize their vulnerable Electrum wallet with a malicious server, they are instructed to "update" their clients with a hacker version, which can eventually result in the immediate loss of funds contained in older versions.
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.
According to slow fog zone news, Electrum fake upgrade tips of the phishing attack has stolen at least 200 BTC, this attack by upgrading Electrum alone can not be avoided, the need for the entire ecological service to make corresponding changes (because Electrum this client is not a full node, and then on the transaction broadcast and the corresponding service side of the message communication, attackers can also deploy malicious server). Slow fog zones remind users that phishing attacks like Electrum require long-term vigilance. The slow fog zone has previously issued an alert for selectrum phishing updates, and hackers who attacked Electrum wallets used Electrum's software to unusually construct malicious software update prompts to induce users to update and download malware usage.

Note: Electrum-XZC is derived from Electrum and uses different seed phrase criteria, so it cannot be imported.
To synchronize information on the Bitcoin blockchain, Phoenix Wallet connects to a random Electrum server. However, to provide greater confidence, it allows you to modify this connection, making it easier for you to connect to a trusted server or your own server.
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.
The best approach is to use Electrum Personal Server, but this is an advanced option and is not without its own dangers.
DEF CON China 1.0 to Technology's.
When testing a pool, connect the equipment to the server for 2-3 days, and then test the results to see which pool is most appropriate for you.
According to The Next Web, the attackers even implemented their own Electrum servers, which hosted the attacked Electrum.
Mr. Ma Jie, General Manager of Baidu's Security Division, also introduced some of the breakthrough points of DEF CON CHINA 1.0 at the press conference. First, DEF CON CHINA.
Chain News, lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payment, implemented using Python, Electrum as a Lightning network node, wallet users do not need to run lightning network nodes to make payments, electrum lightning network nodes have been merged into the Electrum master branch.
