Sandworm: Web Shell Emulation Lab
In this lab, you’ll practice exploiting vulnerabilities in a web application to deploy web shells. First you'll create a simple PAS web shell and execute commands on a remote target system. Next, you'll use your custom PAS web shell to get full shell access on the target system. Finally, you’ll deploy a web shell used by Sandworm, which was used to cause widespread power outages across Ukraine in 2022.
