Analysis Summary
It has been almost six months since an eye opening vulnerability in Microsoft Windows RDP CVE 2019-0708, dubbed BlueKeep, was patched. Today, Security Researcher Kevin Beaumont posted a Twitter thread reporting BSODs (Blue Screen of Death) across his network of BlueKeep Honeypots.
Kevin kindly shared the crash dump with us and following this lead, we discovered the sample was being used in a mass exploitation attempt. Due to only smaller size kernel dumps being enabled, it is difficult to arrive at a definite root cause.
