Hi, I haven't done much hacking lately, so I want to show what other interesting ways there are to exploit programs. One possibility is the format string attack.

Hi, I've been doing some research on recording terminal sessions and found something interesting. A platform called Asciinema. Yup it is as cool as it sounds.

Linux is a multi-user system. Here, several users can work on the system simultaneously. Where are the users stored?

Hi, I had thought about a little troll for a colleague in front of me. Short story he gambles a lot on Steam, I thought how can I torch him a bit, but so that he does not realize that it is me 😄

I took the liberty to play around with Bash a bit. What came out of it, a small reverse TCP shell, which runs as init.d script. The idea was the following: "What if you already have root rights on a system? You don't want to create a new user, which also has root rights, because it might be noticed. So what do you do? Of course you create a backdoor, which runs with root rights. And that's exactly what it is.

Hi, since I have for some time Usbsticks etc to share files have not liked very much I was looking for other ways to provide files conveniently to friends or colleagues at work without the later someone arrives: "can you times, hasste already...".

NetCat as I mentioned in the previous post Post, that it is a Swiss army knife is not yet completely clear. Here I want to show that you can also make portscanns with NetCat no matter if TCP or UDP.

Hi, I decided to write a bit about NetCat, specifically simple bind/reverse shell.

Netcat or nc is a real swiss army knife among network tools. With Netcat you can connect to many services like Telnet, RSH, HTTP etc... To that NetCat can do TCP/UDP. Netcat is very powerful, it is just because it is so powerful also used by hackers to create a backdoor or for bind and reverse shells.
