Like multi-sign wallet, EOS multi-account and private key weight, master account, sub-account, etc. , are in the more secure use of private key exploration, so that private key management more fault tolerance.

Security researchers have found that Google has removed 49 cryptocurrency wallet browser extensions after they were already stealing private keys. These Chrome extensions are aimed at users of encrypted wallets such as Ledger, Trezor, Jaxx, Electrum, Myetherwallet, Metamask, Exodus, and Keepkey.

The root seed in the figure above calculates a 512-bit hash string using the irreversible HMAC-SHA512 algorithm, with Master Private key(m) to the left and Master 256 bits to the left.

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.

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.

Bitcoin Wallet Electrum users face phishing attacks, and when a user updates a client with a backdoor, the private key is stolen and 1450BTC has been stolen so far.

Users of Bitcoin wallet Electrum are facing a phishing attack, according to the Dev 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 (stolen by one user, antimalware firm Malwarebytes and Electrum) had been stolen in phishing attacks that faked Thelectrum upgrade tips, with a total value of about $11.6 million. It is worth mentioning that less than version 3.3.4 of Electrum is vulnerable to such phishing attacks, users using electrum wallets 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 v4.0.0, please do not use the link in the prompt message to update to avoid loss of assets.

In the figure above, the root seed derives a 512-bit hash string by the irreversible HMAC-SHA512 algorithm, the left 256 bit is Master Private key(m) and the right 256 bit is master chain code, and the corresponding 264-bit Master Key (M) can be derived by combining the elliptic curve algorithm of the m-combined derived public key. Chain code serves as the entropy of the sub-key.

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.

The advantage of wallets is that you only need a master key to generate any number of sub-keys. That is, new (public key) addresses can be generated based on the primary public key without the intervention of the private key (the primary and child private keys), and these addresses can actually be controlled by the primary private key.

Nyzo: The private key does need to remain in RAM at all time because it is used to sign all messages. In the end, no amount of engineering (as I can imagine now) will solve this problem forcefully. However, using the proxy key solves the problem: each authenticor's Master key periodically delegates the Proxy key that will be used in normal operations. The master key can be saved in a secure location because it only needs to send a single message from time to time to specify a new proxy key. If the proxy key is compromised, the master key specifies a new proxy key to regain control of the authenticer.

Lightweight Bitcoin Wallet Electrum announced that the next version will support Lightning network payments, implemented with Python, an electrum network node where wallet users do not need to run Lightning network nodes themselves to make payments, and electrum's Lightning network nodes have now been merged into the Electrum master branch.
