Mailchimp security breach exposes DigitalOcean customer data

DigitalOcean has reported a recent security incident at MailChimp, which has resulted in some customers' email addresses being leaked, with a small number of them receiving unauthorised password resets.

Mailchimp has detailed that the attackers used phishing and social engineering techniques. Meanwhile, DigitalOcean's investigation found that an unauthorised email address from the domain was added to its Mailchimp account.

Both companies are still investigating what happened, and, additionally, DigitalOcean has changed its email service provider.
