Inspired by a pretty good write up by Cynofield as to his setup for getting a Raspberry Pi to “phone home”, I thought I’d set out how I do it. I have a machine that lives behind a ‘security’ infrastructure that makes my life a living hell. As a result, I set up automatic persistent reverse shells going back to other machines I use, so if I connect to those machines, I can get into the secure environment, without anything nasty being able to get in with me. ...

Idiot proof setup for persistent reverse shells / port forwards (same thing) under a Ubuntu VM remote and my Dreamhost server, but should apply to nearly* all *nix’s First off, some terms to keep this easy. I want to be able to access my in-office VM, xavier from my server magneto (not my names, but they conveniently complement). xavier is not publicly accessible, but magneto is. I’ll be replacing all of the FQN’s with these terms so expand on your own. In generic terms, xavier is the remote machine (i.e the one behind some NAT firewall or such that you want to get access to) and magneto is the local machine. Its a bit confusing since all of the work is done on xavier, but it makes sense in the long run. Just trust me and get on with it. ...

As was noted in my LENOVO ROCKS post, I recieved a virgin hard drive for a laptop with no disk drives. This is a problem that has been long solved in Linux Distros but is not so good for Windows, but i did find this brilliant guide by Sandip from earlier this year, i just wanted to point out a few difference that i made to the process that i think make it slightly more transparent whats going on. ...

Last week or there abouts, there was a big buzz around the interwebs revisiting Dan Kaminski’s OzymanDNS tool, a perl based toolkit for tunnelling TCP traffic over DNS requests (technically its TCP over SSL over DNS but whos counting) That was originally released mid-2004. I never really found the true source of the new hype surrounding a “old” project (it may have been HAK5’s episode 504 that demonstrated the tool, mubix has put the write up in at room362) ...

Thru my work I’m thrown into alot of technologies that i dont nearly know enough about and as with alot of tech related things, the education scene is basic basic basic..GURU with little or no gradiation, so what I’m going to do is post what i learn when i learn it and where i learn it from and hopefully it’ll be useful for someone else, and I’ll also take the opportunity to rehash stuff I’ve already done. ...
