Linux-Fu: Applications on the Web

Posted on by

Did you know you can run remote Linux GUI programs in a browser with HTML5 support? It’s even secure because you can use SSH tunneling and little trick that means you don’t even need to open additional ports. If this sounds like gibberish, read on, it’s actually pretty easy to get up and running.

I recently was a guest on a Houston-based podcast, and the hosts asked me if the best thing about writing for Hackaday was getting to work with the other Hackaday staff. I told them that was really good, but what I like best was interacting with …read more

A Red Teamer’s Guide to Pivoting

Posted on by

What is hacking and what is network engineering? We’re not sure where exactly to draw the lines, but [Artem]’s writeup of pivoting is distinctly written from the (paid) hacker’s perspective.

Once you’re inside a network, the question is what to do next. “Pivoting” is how you get from where you are currently to where you want to be, or even just find out what’s available. And that means using all of the networking tricks available. These aren’t just useful for breaking into other people’s networks, though. We’ve used half of these tools at one time or another just running things …read more

DNS Tunneling: Getting The Data Out Over Other Peoples’ WiFi

Posted on by

[KC Budd] wanted to make a car-tracking GPS unit, and he wanted it to be able to phone home. Adding in a GSM phone with a data plan would be too easy (and more expensive), so he opted for the hacker’s way: tunneling the data over DNS queries every time the device found an open WiFi hotspot. The result is a device that sends very little data, and sends it sporadically, but gets the messages out.

This system isn’t going to be reliable — you’re at the mercy of the open WiFi spots that are in the area. This certainly …read more

It’s Not a Bridge, and Not a Tunnel. Or, Maybe it’s Both?

Posted on by

The gist of the idea is to suspend an underwater tunnel from floating pontoons. By the time you finished reading that sentence, you probably already had a list of things in your head that seem to make this a terrible idea. After all, it does seem to combine the worst aspects of both underwater tunnels and bridges. But, the idea may actually be a good one, and it’s already being seriously considered in Norway.

You see, Norwegians have a fairly serious obstacle to long distance travel: fjords. The tradition way to cross a fjord is by ferry. One simply can’t …read more
