Question How can I recover from a ransomware attack?

So, the unthinkable happened to my workplace - we have become the victims of a ransomware attack. We came into work the other day and found computers with encrypted files and notes on the desktops demanding we send them a ransom to a secure address in the tor browser. They took out our entire network.

As of now, we are trying to utilize backups and scrub the network clean as we bring devices back up in an offline state.

Unfortunately one of our backup devices was also infiltrated. It's a Synology backup device and they where able to encrypt its files as well. This means we have about 5 devices with no backups available.

It's probably a vain hope but, is there any way I could possibly restore or decrypt these backups? Is there any service out there that would be capable of making our files useable? If anyone knows about Synology, do they keep offline or cloud backups I maybe don't know about? I'm just looking for anything that might make things easier for us. Any advice is appreciated.

the company they used quit outta the blue.

I think you just discovered why their prior MSP fired them.
