Atlassian revealed that unidentified hackers gained access to a vast quantity of data from its group chat service HipChat by breaking into a cloud server owned by the business.
Although Atlassian did not disclose the identity of the prominent third-party software library that was utilised by its HipChat.com service, the business claims that attackers took advantage of a weakness in the library.
The business issued instructions on how to reset passwords to all users whose accounts were connected to HipChat and, as a precaution, invalidated the passwords on those accounts.
The organisation claims that although hashed passwords, email addresses, and names were accessible to hackers, no financial information was revealed.
