Security of Electrum Wallet

Since Electrum was made public, hundreds of independent developers have reviewed it, even contributing over 15,000 commits to the wallet’s software code.
Despite having robust security features, Electrum users still fell victim to phishing attacks, allowing hackers to steal funds through malicious websites. The team later fixed the vulnerability. However, since the wallet does not support automatic updates, users must regularly update the wallet to ensure they are using the latest version.
