Technical Analysis

Evidently this is being used for privilege escalation in ransomware attacks when threat actors have initial access to systems through existing Raspberry Robin, FAKEUPDATES, and/or Qakbot infections. Not necessarily surprising given the Windows print spooler’s popularity with attackers, but the existing intel on Raspberry Robin and Qbot ecosystems is a little light on specific CVE mentions. I was surprised to see the RiskIQ article, especially considering that it’s fairly buried in run-of-the-mill Patch Tuesday roundup drivel in Google search results.
