Shortly after the company was acquired by Chegg, Thinkful, an online education site for developers, confirmed that it had a data breach.
In an email to users, Erin Rosenblatt, the company’s vice-president of operations, said:
“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. As soon as we discovered this unauthorized access, we promptly changed the credentials, took additional steps to enhance the security measures we have in place, and initiated a full investigation,” the executive said.
TechCrunch reached out to Thinkful to ask if the company had been aware of the breach when it was acquired on September 4th, but a spokesperson from the company did not respond to questions.
Additionally, the email to users stated that the hacker could not access certain information, such as government-issued IDs and Social Security numbers, or financial information, with the stolen credentials, TechCrunch reports.
Currently, Thinkful has seen “no evidence” of any unauthorized access to users’ account data. However, it did not rule out any improper access to user data.
