With more and more workloads migrating to "the Cloud", we see post-breach forensic investigations also increasingly moving from on-premises to remote instances. If we are lucky and the installation is well engineered, we will encounter a "managed" virtual machine setup, where a forensic agent or EDR (endpoint detection & response) product is pre-installed on our affected VM. Alas, in my experience, this so far seems to be the exception rather than the norm. It almost feels like some lessons learned in the past two decades about EDR have been thrown out again, just because ... "Cloud".
