How many accounts were compromised?
The breach impacted data related to approximately 107,000 individuals.
What data was leaked?
The data exposed in the breach included email addresses, employers, geographic locations, job titles, names, phone numbers, and social media profiles.
How was Mailchimp hacked?
Hackers breached Mailchimp's internal customer support and account management tools by conducting a social engineering attack on employees and contractors, obtaining compromised credentials. This allowed unauthorized access to select Mailchimp accounts, impacting 107,000 customers. The breach highlights the importance of robust security measures and employee awareness to prevent such incidents.
Mailchimp's solution
In response to the hack, Mailchimp took several measures to secure its platform and prevent future incidents. This included temporarily suspending account access for affected accounts and notifying the primary contacts for all affected accounts within 24 hours of the discovery. Mailchimp has been working with users directly to help them reinstate their accounts, answer questions, and provide additional support. Although specific security enhancements were not publicly disclosed, the company's ongoing investigation aims to identify measures to further protect their platform.
How do I know if I was affected?
Mailchimp notified the primary contacts for all affected accounts within 24 hours of discovering the breach. If you're a Mailchimp user and haven't received a notification, you may visit Have I Been Pwned to check your credentials.
What should affected users do?
In general, affected users should:
Change Your Password: Immediately update your password for the breached account. Make sure the new password is strong and unique, not previously used on any other platform.
Reset Passwords for Other Accounts: If you've used the same or similar passwords for other online accounts, reset those as well. This is crucial as attackers often try using stolen passwords on multiple sites.
Enable Two-Factor Authentication (2FA): Activate 2FA on the breached account. Consider enabling this additional security feature on all other important online accounts to significantly reduce the risk of unauthorized access.
