The email addresses of some MetaMask users may have been exposed to a malicious party due to a recently discovered cyber-security incident. According to parent company ConsenSys, the incident affected users who submitted a customer support ticket to MetaMask between August 1, 2021 and February 10, 2023.
According to the April 14 blog post, unauthorized actors gained access to a third party’s computer system that was used to process customer service requests, potentially allowing them to view customer support tickets submitted by MetaMask users.
