With 10 million registered users and over 50 million unique visitors every month, Stack Overflow is very popular among professional and enthusiast programmers.

In a short note published by Mary Ferguson, VP of Engineering at Stack Overflow, the company confirmed the breach but said it did not find any evidence that hackers accessed customers’ accounts or any user data.

“Over the weekend, there was an attack on Stack Overflow,” Ferguson said. “We have confirmed that some level of production access was gained on May 11.”

Though the company did not share details on how attackers were able to breach Stack Overflow and the actual extent of the breach, Stack Overflow said the company is patching all known vulnerabilities.

“We discovered and investigated the extent of the access and are addressing all known vulnerabilities,” Ferguson said.

“We have not identified any breach of customer or user data. Our customers’ and users’ security is of the utmost importance to us.”

However, Stack Overflow has promised to share more information about the incident after its investigation is completed.

“Our customers’ and users’ security is of the utmost importance to us. After we conclude our investigation cycle, we will provide more information,” Ferguson added.
