Progress Software has told ShareFile customers to shut down the Windows servers running their Storage Zone Controllers, confirming to The Hacker News that it is responding to a "credible external security threat."

The company has temporarily disabled access to the affected accounts, a step it says it took "out of an abundance of caution" while it works with internal and external security experts. It says it has no indication of unauthorized access to any ShareFile accounts or data, and that it notified customers after learning of the threat.

What Progress has not said is what the threat is, who is behind it, or whether any controller has been broken into.

The order became public when a customer posted the company's email to Reddit's r/sysadmin a few hours ago. Progress confirmed the disruption on its status page, listing Storage Zone Controller customers as "not operational" and the incident as under investigation as of a 12:12 p.m. EDT update.
