Middleware provider Kaseya said Thursday it received a key to unlock the encrypted computers of more than 1,000 companies after a Russian-based hacking group locked the systems as part of a massive ransomware campaign earlier this month, according to AP.
Why it matters: The company would not disclose how it obtained the key or if it paid a ransom to REvil, the group behind the breach, but it said the key was working and its customers around the world were regaining access to their systems.

REvil conducted the campaign by exploiting a flaw in software that Kaseya supplied to its customers, who are themselves managed service providers that provide IT management and other core network functions for businesses.
The big picture: Kaseya's announcement comes a bit over a week after dark web sites that REvil used to facilitate its ransom negotiations mysteriously went offline.
It's still unknown whether the sites went down because of a technical problem, a law enforcement operation, or some other explanation.
REvil at one point demanded $70 million to restore data they claimed for ransom through the July 4 weekend operation that targeted Kaseya.
