While Shannon’s on vacation our friend Jenn Cutter from Open Alpha joins us to talk about the recent developments in PSP hacking and homebrew.

The PSP homebrew scene has grown more interesting over the past little while since the user base has been sectioned off into different camps based on the particular unit they purchased and whatever firmware they are using. Thanks to the efforts of Team Typhoon, ChickHEN (homebrew enabler) permits owners of all models to run the unofficial apps and games they’ve grown to love without touching the flash of the PSP, so there’s no worrying about turning it into a brick. No one likes expensive bricks. Keep in mind that ChickHEN is not a piracy tool so don’t expect to run any type of backups though it. Davee has the lowdown on the latest release which can be downloaded here. If you are curious or sceptical, feel free to check out video proof that it works on PSP 3000s.

Matt answers your questions about storage area networks and recommends QNAP. If you’re feeling hands on rolling your own is a great option too. Matt points out his favorite hardware like 3Ware RAID cards, Transcend IDE Flash Modules, and the Intel Storage Server SSR212MC2. Software wise it’s worth investigating Freenas, and SAN Melody.

Continuing on with Eighty’s segment on extracting windows executables from packet captures and Mubix’s segment on network tap analizers, Darren’s taking a look at the open source tool ngrep. If you’re familiar with grep you’ll be at home with this tool. Darren demonstrates using the tool to filter packets from a live capture using a Network Monkey. Alternatively it can be used with pcap files.

Taking a trip around your network with Nmap

This week I talk about network scanning with the difinitive open source security scanner Nmap.

Scanning ones own network is ideal whether simply to know your neighbors or keep inventory of your assets. As a black hat it can be the first step in enumerating a target environment and looking for weaknesses.

In order to perform our scan we’ll simply need a copy of Nmap. It’s available for Windows, Mac, and just about every flavor of Linux, BSD and more. If you’re on a debian based system like Ubuntu a simple apt-get install nmap should do you good. If you’re looking for a security distribution with nmap (and a ton of other great tools) built in can’t speak highly enough of BackTrack. Version 4 beta was just recently released.

The underlying workings of Nmap are better explained in this guide but suffice it to say it takes advantage of TCP’s 3-way-handshake and other fancy raw packet tricks to find hosts and open ports. In this segment I set out to introduce the concept and get you started with a few basic examples. If you’re interested I recommend Nmap Network Scanning and the official man pages as further reading.

The segment details some commands and their usage in a searching for open MS terminal servers scenario. I highly encourage you to provide feedback either by way of email (darren AT hak5 d0t org) or on our forums. I enjoy doing segments like these but if you have any corrections (more than one way to skin a cat), suggestions for future topics or hacks of your own please let me know.

Obscure your OS Fingerprint

OSfuscate 0.3 by Irongeek is used to camaflouge or obscure your Windows OS. With this tool, it’ll show up like another OS of your choice, nothing at all, or even a printer. OSFuscate could be used if you are on a hostile network and need some sort of cloak while going along in your daily routine. It is important to note that this is not a fool proof method for hiding yourself on a network and should not be relied upon for security. however, as a layer of obscurity in addition to your regular security practices you may want to consider it.

It’s a simple process to set up OSFuscate on your machine. Go to Start->Run->Regedit. Back up your Parameters folder, found under System->CurrentControlSet->Services->Tcpip->Parameters. You can do this by simply right clicking on the folder, and choosing export. This is basically just to keep yourself form messing up your OS in the process and having no way to return it to normal. You’ll notice on Irongeek’s website that certain Parameter Registry keys will be subtly changed. You could do this by hand, but OSFuscate makes this task super simple. Open OSFuscate, and choose an OS that you want to pretend to be. Restart your computer and the differences should be in place! Now if someone running NMap snoops your computer, they’ll see some other OS other than what you actually have.

You can find more information at Irongeek’s Website. And as always, you can email me with any comments or suggestions.

as it really helps us out.
