<p dir="ltr">Some of the kits used by the perpetrators have had their decryption keys recovered.</p>
<p dir="ltr">Some of the early ones (they still float around) also actually delivered the decryption key with the payload, if you know where to find it (Google is your friend).</p>
<p dir="ltr">Kaspersky has a tool for attempting decryption with known keys. Other anti-malware vendors may have similar tools.</p>
<p dir="ltr">If you do recover the files, keep only what you need and can confirm are clean, and nuke the system. It is entirely possible that along with encypting your files, a secondary payload has been delivered onto your system, and you just can't trust it any more.</p>
<p dir="ltr">Then invest in an appropriate backup and recovery solution, develop procedures to meet your organisation's RPO and RTO requirements, and stop worrying about ransomware.</p>
