WASHINGTON (Reuters) - The FBI is investigating whether the hackers behind a series of intrusions at U.S. federal agencies and companies also broke into project-management software created by the Czech-based company JetBrains in order to breach its customers, two people familiar with the investigation told Reuters on Wednesday.

Privately held JetBrains produces software called TeamCity that is used by tens of thousands of customers to construct other software. Among its customers is SolarWinds, JetBrains Chief Executive Maxim Shafirov said from St. Petersburg, Russia, where JetBrains has offices.
