Blue explores the dated, but widespread EternalBlue exploit. This exploit was used in the WannaCry ransomware attack which crippled healthcare systems and spread to millions of computers in a matter of days. In this room we are prompted to exploit this vulnerability using Metasploit.
Ice is the extension to the Blue room. In this room we learn more about windows recon, exploitation and escalation. This box uses a vulnerable service called Icecast which allows us to access the machine using metasploit, then elevate those privileges by abusing a spool process.
