Get Permission OpenWRT, an open-source project that develops operating systems, firmware and other software for connected and embedded devices, is investigating a data breach after a hacker gained access to an administrator account over the weekend, according to posts on the project's message boards. In a post, the OpenWRT administrators note the exact cause of the breach, which was discovered Saturday, is still being investigated. "It is not known how the account was accessed: The account had a good password but did not have two-factor authentication enabled," according to the message board post. The initial investigation showed that the hacker was able to download a community user list that contained email addresses, user handles and some statistical information about the community's users, according to the post.
