--[ 9. Conclusion
Of course, the chosen target was just an excuse (as many vulnerabilities
have already been identified and exploited in the past) for presenting
the very subject of the article, which is the optimization of command
injection in the context of using a limited number of characters. We have
demonstrated that even with just a few characters at our disposal, we are
capable of writing a stager (in a file) that can execute a real malicious
payload and thus compromise a device.

I'd like to thank all the people we have come to know and will come to know
in our lives as hackers, as well as all those who have made the effort to
document their research work, and will do so in the future.
We can finally become immortals. Thank you for everything.
