All About Lightning Electrum
GDAX announced that GDAX has gone offline and Coinbase Pro has been officially launched. After June 29, GDAX will be directed to Coinbase Pro.
GDAX announced that BCH-EUR has entered the "full trading" 麵 trading) mode. On the GDAX, BCH was up 0.82% at 1,330.87 euros.
B: Electrum server can customize messages to appear in the user's electrum light wallet software, giving hackers a chance to broadcast phishing messages.
For example, by trading under the chain, or by transferring funds to the startup's GDAX exchange, free transfer of Coinbase Bitcoin, etc.
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.

qtum-electrum adds support for offline staking.
Like Bitcoin's core wallet, Electrum Wallet allows users to control their own funds and private keys. Electrum wallets' private keys can also be exported and used on other supported wallets to access funds. Electrum apps are available for Windows, Linux, OSX and Android, but do not support iOS and browser clients.
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. Slow fog reminds users that when transferring money, special attention needs to be paid to whether the destination address is replaced, which is a very popular method of currency theft recently. 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.
Coinbase changed the name of GDAX to Coinbase Pro.
In December 2018, for the first time, we discovered and alerted an attacker to a messaging flaw that exploited the Electrum Wallet client to force an "update prompt" to pop up when a user transfers money, inducing the user to update the download malware and then carry out a currency theft attack. This "update tip" 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 the show doesn't fully count that hundreds of bitcoins have been stolen in this phishing attack over the past year or so. Although in early 2019 Electrum officials said they would 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 older version (less than 3.3.4), and the older version is still under threat. However, we do not rule out a similar threat to the new version. Recently, slow fog technology anti-money laundering (AML) system through continuous tracking found that one of the attackers wallet address bc1qcygs9dl4pqw6atc4yqurzd76p3r9cp6xp2kny has stolen more than 30 BTC, the crime lasted six months, and recently is still active. We would like to remind Electrum users that the new version of Electrum in this Update Tip is likely to be false and that if installed, transfer Bitcoin out in another security environment in a timely manner. At the same time, we call 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. Finally, identify electrum's official web address.
As mentioned earlier, because electrum light wallets are different from Bitcoin light wallets such as MultiBit or Breadwallet, they cannot communicate directly with bitcoin full nodes and can only communicate with electrum.
Transaction information should be signed offline using offline Bieber wallets or Bitcoin Core or Electrum. The Bitcoin transfer can be completed by returning the signed message to an online wallet or online broadcasting tool and broadcasting it to the outside world.
Given that digital currencies are still in their infancy, we believe that digital money markets are inefficient, and we know that one way to exploit market inefficiencies is arbitrage. Arbitrage opportunities occur when the price of an asset (in our case a currency or token) is traded at different prices. For example, if Bitcoin trades at $15,000 on GDAX and $15,050 on Gemini, you can simultaneously buy on GDAX and sell on Gemini for a profit of $50. You can then transfer funds between exchanges and repeat the process.
Coinbase says GDAX was originally built for institutions, but has since attracted individual customers. Coinbase Pro will be easier to use, with customers' GDAX accounts and Coinbase Pro accounts connected and automatically checking the balance of any account. Coinbase Pro has the same transaction fees and security features as GDAX. The two exchanges will be open until June 30 this year, after which users will move to Coinbase Pro.
To simplify the foundation's money management, the Litecoin Foundation is moving from multi-signature Electrum-LTC wallets to BitGo's multi-signature wallets, officials tweeted.
According to Johnwick.io, we will continue to monitor and track further movement of funds after a recent user submitted a coin-losing incident claiming that the download used electrum wallets had been phishing attacks, losing more than 700 bitcoins, and that the stolen address had been added to the Devi AML system. It is reported that malicious website (electrumsecure) fake Electrum website phishing attacks, to guide users to download the wallet, in order to steal the user's private key and other sensitive data. De-dimensional Security Labs hereby reminds users not to install electrum wallets from unknown sources at will to avoid asset losses. Electrum Official Website: electrum.orgElectrum Phishing Website: electrumsecure.
The Electrum team has announced the attack in an official tweet, saying that "this is an ongoing phishing attack on Electrum users" and reminding users to check the authenticity of the client's source before logging in. The team published its official website, and electrum clients downloaded elsewhere may be problematic.
Electrum tweeted today about the incident, saying it was "a persistent phishing attack on Electrum users" and imploring users to check the effectiveness of the resources they log on to.
By default, electrum wallets are randomly connected to a set of Electrum servers. From a privacy perspective, this is not a good thing because it discloses your wallet address and balance to unknown third parties. And unfortunately, many public Electrum servers are run by individuals or groups of blockchain analytics companies or worse. Therefore, if you are using an Electrum wallet, it is generally recommended that you run your own Electrum server and then connect the wallet to that server.
As an additional bonus, users can transfer their funds to Coinbase's sister exchange GDAX for free. However, coinbase is not suitable for large cryptocurrencies traders because only four cryptocurrencies are currently supported and transaction costs are high.
GDAX, Coinbase's digital trading platform, has issued detailed token listing rules for the platform, the GDAX Digital Asset Framework, which set out a number of criteria that must be met, including whether the asset complies with GDAX values and U.S. securities regulations. Whether tokens are classified as securities or are primarily used for fund-raising is not taken into account, as long as tokens can be clearly and well-founded and used. Standards are not certain, and GDAX reserves the right of final interpretation.
In August-September, Bitcoin wallet Electrum was hacked twice, and according to multiple sources, at least 1,450 BTCs worth $11.6 million were stolen from phishing attacks that faked Electrum upgrade tips.
