Thinkful, an online education site for developers, has confirmed a data breach, just days after it confirmed it would be acquired.

“We recently discovered that an unauthorized party may have gained access to certain Thinkful company credentials so, out of an abundance of caution, we are notifying all of our users,” said Erin Rosenblatt, the company’s vice-president of operations, in an email to users.
