In this video, you'll see a simple malformed packet attack which takes down an FTP server.
- [Voiceover] Websites are not the only targets…for denial of service attacks.…Other services, such as the file transfer protocol,…FPT are internet facing and so also at risk of being attack.…I use my Windows 7 machine as the target for this attack.…I've installed the small FTP server, version 0.99,…and we can see the shortcut on the screen.…This is a very simple FTP server…and I don't need to do any configuration so I'll start it.…The software is loaded but the server…isn't currently listening for connections.…
I'll press the start icon to activate the server.…Okay, it's now listening.…In Kali, I'll open the terminal window…and I'll start telnet.…I need to make sure that I get a correct character turn…and line feed when I'm sending data…so I'll set that now.…Okay, I'm ready to connect to the FTP server.…I'll do that using the open command…noting that I also need to specify port 21 for FTP.…
We can see that the FTP server displays…the connection on its panel.…I'll now enter a known user name.…The server displays this input on its own panel…
