According to Reddit user u/normal_rc, electrum's wallet was hacked and nearly 250 bitcoins (243.6 BTCs, nearly $1 million) were maliciously stolen, according to coinelegraph. Electrum then confirmed that the attack included creating a fake version of the wallet to trick users into providing password information. Electrum responded on Twitter that "this is a persistent phishing attack on Electrum users" and warned users not to download Electrum from any source other than the official website.

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.
There are two main types of passwords that provide security for Bitcoin: one is a hash algorithm password used in the "coin digging" process, and the other is a digital signature algorithm on the blockchain. When digging coins, the hash algorithm calculates a random number for each block, a process that is easy to verify, but difficult to find by the cracker.
Earlier this month, Electrum detected a DoS attack on its network, allegedly launched by a malicious botnet with more than 140,000 machines, designed to provide Electrum to users.
