Based in Melbourne, Australia, and established more than two decades ago, SitePoint provides users with access to tutorials and books that can help them learn the basics of web development.

Last week, the company started informing users that some data was accessed by a third-party during a cyber-attack that was “recently confirmed.”

The culprit, SitePoint said, is a third-party tool that it uses to monitor its GitHub account, “which was compromised by malicious parties.”
