--[ 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. |

--[ 10. Acknowledgments (527e876c0d7e3049d1d99f00f3fbf9a9b0c63ccf) |
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. |
