In order to use SSL in your reverse shell, first you need to generate a SSL certificate for the tunnel.
We get a reverse shell using the webshell and add our public key to SSH as webadmin; We use Luvit, a repl for lua to get shell as sysadmin using sudo and gtfobins; We finally edit the writable file /etc/update-motd.d/00-header to add root SSH keys and login as root; Recon Nmap Lit is a toolkit designed to make working in the new luvit 2.0 ecosystem easy and even fun. In most cases, you just want to install lit as quickly as possible, possibly in a Makefile or make.bat in your own library or app. We maintain several binary releases of luvi to ease bootstrapping of lit and While in a Linux terminal on a virtual machine, I came across a need to get a bash shell on a particular user, running Luvit repl. I had never previously heard of the program and found very little documentation on it, none of which looked anything like what was shown in the terminal. The image above shows that I can run something called luvit. That prompted more googling and trying to understand whats going on.

Lua offers a higher-level function to load and run libraries, called require.Roughly, require does the same job as dofile, but with two important differences.First, require searches for the file in a path; second, require controls whether a file has already been run to avoid duplicating the work. Because of these features, require is the preferred function in Lua Reverse shell is a way that attackers gain access to a victim’s system. In this article, you’ll learn how this attack works and how you can detect it using Falco, a CNCF project, as well as Sysdig Secure.. Sometimes, an application vulnerability can be exploited in a way that allows an attacker to establish a reverse shell connection, which grants them interactive access to the system.
If you’re on Linux, FreeBSD, or OSX, run the following script to download luvi and build lit and luvit for your platform: curl -L https://github.com/luvit/lit/raw/master/get-lit.sh | sh If you’re on windows, run the sister command in your cmd.exe command prompt (requires Powershell >= 3.0).

Now execute the command and then connect again in another tab with ssh and we get a reverse connection there. The gained shell is called the reverse shell which could be used by an attacker as a root user and the attacker could do anything out of it. During the whole process, the attacker’s machine acts as a server that waits for an incoming connection, and that connection comes along with a shell. Creating Reverse Shells.
