Workday confirmed that it was targeted in a data breach involving a social engineering campaign, which resulted in hackers gaining access to public business contact information from its third-party CRM platform.

The HR tech giant said it had no indication of any unauthorized access to customer systems, but has not ruled out a breach affecting customers' personal information.

Workday says attackers obtained employee contact information in a recent breach, but did not reach customer human resources systems. In a blog post, Workday confirmed that hackers accessed personal data in a cyberattack that targeted the software giant earlier in August.
