BITCOIN, Jan. 8 (Reuters) - Popular wallet developer Electrum has released an emergency patch for a key vulnerability in bitcoin wallets. The vulnerability allows any website hosting an e-wallet to potentially steal a user's cryptocurrency. The vulnerability meant that the password was exposed in the JSONRPC interface, making the hacker completely in control of the wallet. However, the first patch failed to fix the problem, forcing Electrum to release an updated version again Sunday night.

Lesson 1: Third-party Electrum servers can link your two transactions together. This can be avoided by running your own Electrum server, supported by your own full node.
Because of the public nature of the blockchain ledger, the Tor protocol cannot hide the original BCH address and transfer destination, and users who want to be thoroughly encrypted also need VPN and Tumble, which can make it easier for investigators to determine IP, and Tumble can confuse the sender and receiver of a BCH transaction, and the use of the three greatly enhances transaction privacy.
Technology vulnerabilities have led to the exposure of thousands of Bitcoin wallets and the Electrum client's need to fix them.
