Technical Analysis
This was discovered because of zero-day exploitation perpetrated by a skilled adversary — final payload was Nokoyawa ransomware in at least one case, as Kaspersky details here. We’ve seen a sustained burst of driver exploitation by a range of threat actors the past two years. The trend continues.
Patched in April 2023 Patch Tuesday, so grab those updates quickly as always!
