Marketing automation platform Mailchimp revealed recently that its security team discovered unauthorized access to one of its tools on January 11. The tool is used by the company’s customer-facing teams for support and account administration.
According to Mailchimp, the hacker targeted employees and contractors in a social engineering attack and used compromised employee credentials to gain access to some Mailchimp accounts.
“Based on our investigation to date, this targeted incident has been limited to 133 Mailchimp accounts. There is no evidence that this compromise affected Intuit systems or customer data beyond these Mailchimp accounts,” the company said in a notice published on its website.
