MetaMask Security Breach: Third-Party Provider Compromised, Exposing User Emails

A recent cybersecurity event has put MetaMask users on high alert. TmZ.NG reports that the personal email addresses of some users have been exposed to malicious actors. The incident affected those who submitted a customer support ticket to MetaMask between August 1, 2021, and February 10, 2023.

ConsenSys, MetaMask’s parent company, explained that unauthorized individuals accessed a third-party computer system used to process customer service requests. This security breach potentially allowed the intruders to view customer support tickets submitted by MetaMask users.

While the tickets did not request more information than necessary, they did include a “free text-field,” which some users may have used to submit personally identifying information. Consequently, data such as financial details, names, birthdates, phone numbers, and addresses may have been exposed.

Although ConsenSys does not ask for personal information during customer interactions, some users may have provided it voluntarily. The breach is estimated to have impacted up to 7,000 MetaMask users who submitted customer support tickets.

Keystone, a hardware wallet provider, warned MetaMask users that the breach might lead to an increase in phishing emails. Cybercriminals could use the exposed email addresses to target potential victims with deceptive messages.

To enhance security, ConsenSys has taken measures to prevent unauthorized access in the future. Tickets submitted after February 10 should not be affected by the breach. The company has also notified the Data Protection Commission of Ireland and the Information Commissioner’s Office of the United Kingdom. Furthermore, the third-party customer service provider is collaborating with a cybersecurity and forensics team to conduct a thorough investigation.

MetaMask previously faced criticism from privacy advocates for logging users’ IP addresses. However, the company addressed these concerns in March, updating its app to give users more control over which providers could access this information.

Online Safety Measures for MetaMask Users

MetaMask users should take additional precautions to protect their accounts and personal information following the cybersecurity incident. Here are some vital tips to help bolster your online security:

Enable two-factor authentication (2FA) for your MetaMask account and any associated email addresses.
Use strong, unique passwords for all your accounts and avoid reusing them across multiple platforms.
