Mailchimp

In January 2023, Mailchimp detected unauthorized access within their infrastructure by an intruder who gained access to one of the tools used for user account administration and customer support. This breach was the result of social engineering attacks targeting Mailchimp employees, leading to compromised account credentials. Although Mailchimp stated that no sensitive information was stolen, the breach potentially exposed customers' names and email addresses. This incident highlights the dangers of social engineering and the importance of strong cybersecurity measures to protect against unauthorized access.
