How to Install Kali Linux on VirtualBox
Virtual machines are super useful! They allow users to create isolated environments for testing, running software that the host machine can’t, privacy reasons, and many more. At UGASCS we mainly use VMs to host all of the tools we need for CTFs and other cyber events.
This machine was challenging, but I learned a lot. I learned how to make “smarter” shells and how to upload the pspy script to a remote server. I wonder if I could have completed this machine without adding my public ssh key, because at the moment it is very identifiable.
This was one of the first boxes I completed and it was difficult. It took me the longest time to enumerate the directories and finally find what I was looking for. Overall, I learned more about using my resources and double checking where I had thought I already looked.
This Try Hack Me room guided users through the basics of web application pentesting. I learned about SMB enumeration and bruteforcing domains. This walkthrough also introduces bruteforcing logins with hydra and once the machine is compromised, elevating user privileges.
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.
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.
Vulnversity walks through how to preform recon on targets and look for possible points of entry for payloads such as reverse shells. On this box port 3333 is running a webserver. After dirbusting the webserver we find a path called internal where we are able to upload php files.
