The forum supporting the community for OpenWrt suffered a security breach over the weekend. Hackers were able to download a copy of the user list that contains email addresses, handles, and other statistical information about the users of the forum. The breach of an open-source forum may not seem on the surface like such a big deal, but the forum is often visited by those developing commercial routers, devices and software based on the Linux-based software. Administrators advised users to reset all passwords, flush API keys from the forum, and refresh any Github login or OAuth key.
