On the night of June 23, the mailing list provider of the well-known Ethereum network was compromised by a hacker attack. Cybercriminals gained access to a contact list of 35,794 email addresses by using the '[email protected]' address to send phishing messages. These emails contained a link to a malicious site designed to automatically empty the crypto wallets of users who authorized the requested transaction.

Details of the attack: objectives and methodology

The fraudulent message conveyed by the hackers advertised a false collaboration with Lido DAO, promising an annual return of 6.8% on the cryptocurrency funds deposited. According to Ethereum's official statement, users who launched their digital wallet to authorize the transaction risked losing their assets immediately. This sophisticated phishing operation exploited the trust placed in the Ethereum brand and official communication to mislead users.

Ethereum Response and Mitigation Actions

The Ethereum security team responded promptly to the attack, launching a series of internal investigations to understand the extent of the breach and implementing corrective and preventative measures. Among the actions taken were timely notification to users through various communication channels, strengthening the security infrastructure to prevent future breaches and migrating some email services to more secure providers. Furthermore, the malicious link was reported to major blacklists and was blocked by most web3 digital wallet providers and Cloudflare.

Implications and advice for the community

A portion of the email addresses affected by the attack belonged to the Ethereum blog syndication list, with 81 of these already known to the hackers. Despite the scale of the attack, analyzes of the transactions reported no significant loss of funds. This event highlights the importance for users to maintain a high level of vigilance and carefully check emails and offers that seem too tempting. In an advanced and rapidly evolving technological sector such as cryptocurrencies, prudence and correct cybersecurity education remain essential to protect your digital assets.
