Progress Tells ShareFile Customers to Shut Down Storage Zone Controllers Over Security Threat

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 or who is behind it.

The order became public when a customer posted the company’s email to Reddit’s r/sysadmin on July 10. 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.

Only the Storage Zone Controller is affected, not standard cloud-only ShareFile accounts. The controller is a server that a company runs itself, so files can stay on its own storage while it still uses ShareFile’s cloud to share and manage them.

The controller usually sits at the network’s edge, reachable from the internet. That exposure makes it both useful and a target. Ordering customers to take it fully offline, rather than just patch it, is a notable step.

That choice is itself a tell. If a fix for this threat existed, Progress would be telling customers to apply it; the shutdown order suggests there is none yet. That usually means a newly found flaw the company is racing to close, though the same step would also fit a threat a patch cannot address, such as stolen keys or a problem on Progress’s own side.

Its statement that no accounts or data were accessed is careful wording, too, and does not rule out trouble on the controllers themselves.
