Simple NASM assembler code leaves me baffled

Ok, so you all know I’m new to assembler. I have started using NASM so that it is easier to look at the shell code. I’m trying my best to get this tiny piece of code to run. However it keeps segfaulting. Can anyone explain. It is the mov to [esi + 2] that causes [ READ MORE ]

Social networking – What do we actually use it for?

So, before I get a torrent of abuse from this one, I’d like to point out that I am a user of social networking. I use both twitter and facebook to some extent, mainly to promote my book and blog. Though recently I have been wondering about the real use of social networking. Granted we [ READ MORE ]

Converting a decimal number to ip address in python

So, I was messing around with something tonight where I needed to get the ip address of a machine from decimal format into the traditional string as we know it. Now, an ip address is literally just a 32 bit number really, and thus the ip address. 192.168.0.1 converts into 11000000101010000000000000000001 in binary, or 3232235521 [ READ MORE ]

Learning Assembler: The easy way!

Well, I’ve finally succumbed to the pressure from…..well…me. As many of you know, I’m interested in the world of security and I thought one way to take this to a new level would be to learn the language of the shellcode, Assembler. For those of you who think I’m being vague, I’m talking about x86 [ READ MORE ]

Encoding Video for Cell Phones

Recently as many of you will know, I managed to get rid of the ridiculously appalling Skype S2 Phone, and replace it with a cheap, but very functional Sony Ericsson T715. Now, I’m not going to get into the various merits of each, suffice to say the SE has a decent resolution screen, at 320×240 [ READ MORE ]

Bluetooth Remote Control – Awesome Technology

A few years ago I bought a Sony Ericsson w810i and absolutely loved it. A lesser known feature at the time was the bluetooth remote control functionality which allowed you to control your PC via your cell phone. Pointless? Well, not entirely. The people at Sony had built 3 profiles. They were Media Player, Presenter [ READ MORE ]
