Hackers launched a denial-of-service (DoS) attack on a well-known wallet Electrum server, according to Johnwick.io. Hackers used botnets of more than 140,000 computers to attack Electrum 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. De-dimensional Security Labs recommends that users of electrum wallets be updated to the latest version of the client through the official website and never use the link in the prompt message.
According to Bleeping Computer, the BTC wallet app Electrom accused a phishing product called Electrum Pro of stealing a user's seed key on May 9 on GitHub and registering a domain name called electrum without Electrum's permission. The Electrum team noted that there was a piece of code indicating that the counterfeit product might have taken the user's seed key and uploaded it to the electrum. Affected users should transfer funds from BTC URLs managed by Eletrum Pro.
From this Phishkingz can get login details synchronization, mnop phrases, as well as any PGP private key and password and PIN code.
Star Daily News 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. (Cointelegraph)
The user signs a string unique to their address to generate a 164-character hedding string. This is called tag seeding. Signed-seed is used as the private key to encrypt the PGP private key in the PGP key pair.
Although factors such as contribution, reputation, philosophy, etc. may be considered in decision-making, but to be honest, Bitcoin Core is not a democratic organization. Core’s top leadership team of 5 members, the party and government, has undisputedly controlled the administrative power of the Core client. "Which codes can be merged into the Core client" and personnel rights: "Who can have the authority to merge codes (PGP KEY)". Who can have the authority of Core’s PGP KEY is made by the current PGP KEY group of 5 people to make a black-box decision. Leader replacement can only be specified by the current leader. Note: These two powers are powers for the Core client, not for Bitcoin.
There are different certificates in different applications. Examples such as public key certificate PKC, PGP certificate, SET certificate, and so on.
September 19 (Xinhua) -- Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Health 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.
If you want to import a private key into a hardware wallet such as a ledger, you need to perform additional steps. First, you need to import the private key into a wallet such as Electrum before you can send coins to your ledger address.
Zimmermann wrote PGP 1.0 in 1991 with a 128-bit key. PGP's name is interesting - Pretty Good Privacy (a pretty good privacy tool). This tool shines a light on many people, especially individuals or agencies who do not want to be monitored by the U.S. government. Zimmermann alerted the U.S. government by allowing people to download PGP at will on Ftp servers. The FBI tried to prosecute Zimmermann and prevent him from spreading the tool.
He even provided proof of encryption with his e-mail PGP key.
You may have noticed an important difference between the MyMonero type and the Electrum seed type. MyMonero creates a viewing private key by hashing a random integer, while the Electrum type hash pays the private key. This means that the seeds of 13 and 25 words are not compatible - it is not possible to create an Electrum type account that matches the MyMonero type account (and vice versa) because viewing key pairs is always different.
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-signature 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 a message flaw that allows an attacker to send update prompts through a malicious ElectrumX server. This update prompt is very confusing for 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. In this slow fog remind users, transfer, need to pay special attention to whether the destination address is replaced, which is a very popular recent way to steal money. 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.

PGP 2.0, which he was involved in developing, is considered to be the first truly secure version of the program, and a "web of trust" key signing model has been developed that establishes a trusted identity through PGP 2.0. And this trust model is the key to PGP's success.
One of the most common uses of PGP is to protect e-mail. PGP-protected e-mail messages become a string of unreadable characters (texts) and can only be decrypted using the appropriate decryption key. The working mechanism is the same as encrypting text messages, and there are software applications that support PGP functionality on top of other applications, effectively adding encryption to unreliable secure communications.

Even now, PGP is one of the most popular encryption protocols in the world. He became a well-known figure in encryption because of PGP.
Bitcoin Wallet Electrum confirms a phishing attack against its users, reminding them not to download Electrum Wallet software from any channel other than the official website. Earlier media reports said Electrum users had maliciously stolen millions of dollars worth of cryptocurrencies. Hackers create Electrum wallet software with malicious code, induce users to download, and trick users into providing login information such as passwords to commit theft.

Malicious wallet software: A wallet software that sends a private key to a central server to steal the victim's coins. "Electrum Pro" is a notorious example, however.
RSA's patented algorithm incorporates PGP. Phil Zimmermann defended himself by saying he was not selling PGP tools, but spreading them as a research project.
In 2016, CSW publicly declared itself Tonmoto and released the so-called "PGP key of Mr. Tsung", which was later proven to be false.
In a letter to the Florida court and Judge Reinhart, Debo stressed that he had never had any contact with David Kleiman. The letter also insisted that CSW "does not have a unique private key for my PGP key on the Genesis block"
VGP: Very Good Privacy (VGP) is an end-to-end group password system library created by Duality that provides an encryption layer that exceeds the current Pretty Good Privacy (PGP) encryption. VGP uses public key cryptography, symmetric encryption, Diffie-Hellman key exchange, and hash values for public key fingerprinting.
