Atlassian’s group chat platform HipChat is notifying its users of a data breach after some unknown hacker or group of hackers broke into one of its servers over the weekend. Hackers stole a significant amount of data, including group chat logs, email addresses and hashed password information. HipChat did not say how many users may have been affected by the incident, but the company is taking several proactive steps to secure its users. There is no evidence that the attackers have accessed anyone’s credit card or financial information.
