I have been intrigued by nmap’s feature to scan a target using an idle zombie pc which has an incremental ip id. I have also been intrigued by scapy. Finally I have also been intrigued by metasploit. At first I combined nmap and metasploit and the end result was, that I was not able to get the IPIDSEQ module to work. So I turned to scapy and tried porting the metasploit module to python. It was fun and I finally employed python for something besides playing with it to learn.

I’ve also finally learned why it’s nice to prepend your output with “[*]”, since I’ve been lazy with the verbose output I have just used the one from scapy to know if my script should output or shouldn’t output verbose messages. This means that the output gets cluttered. So by prepending “[*]” you can just grep the results to have a clear view of what the script is doing without the scapy stuff in between it.

Finally scapy is a real nice toy. I had to implement 0.0 code to support cidr notation. So when you for example want to scan a /24 range you can just go like: “”. isn’t that neat? Hope you enjoy it and find a way to use it. For me it was more fun to write it and learn a lot along the way, then the actual goal I wrote it for. oh btw the non-verbose output looks like:

[*] = Randomized

oh a second btw I recommend putting the timeout/waittime on 5 or something like that.

Well I’ve been developing this for a while now and still haven’t finished, mainly because I’ve got little time to spare for coding. Previously I wrote about using somekind of ping to see if your computer is still connected to the net. The solution is fun but it will not prevent forensic analysis of your computer. I have expanded upon that previous post and started to write a toolkit which could be used if we assume the following:

You want to prevent live-forensic analyses of your computer at all costs. You don’t care about normal forensic analysis because your harddisk is encrypted and you have used a real long password and a keyfile.

So with that in mind I started to construct something which frustrates live forensics and at the same time is easy to expand. If you are concerned about normal forensic analysis you can always turn to some of the current anti-forensics projects like the one at metasploit.
