Can You Spoof IP Packets?
nweaver writes "Spoofed IP packets are still believed to be a significant problem for the Internet. But are they? The Spoofer Project is attempting to measure the problem. Apparently, 80% of the IP addresses measured no longer support spoofing! Their methodology is simple: have users download a client which attempts to spoof packets to the monitor. Using these packets, they can determine the filter rules. So everyone, download the client and help!"
Oh yes! Everyone download this executable from known IP Spoofers and run it. It won't root your system, we promise...
Even you can help the next generation of scammers find an ISP to call home!
Job? I don't have time to get a job! Who will sit around and bitch about being broke and unemployed then?
Oh wait. This isn't an "Ask Slashdot"?
Nevermind...

1. Write a piece of software claiming to help monitor spoofed IP packets but really it does something more sinister.
2. Post a story to Slashdot with a link to the software on an MIT server and ask people to run it on their internal networks and send the data back to the author.
3. ???
4. Profit and say to yourself, "suckers"
Maybe I'm too paranoid. But this is a good example of how social engineering can be used to get you into places you shouldn't be. I guess the source cod

"have users download a client which attempts to spoof packets to the monitor"
But my monitor does not have an ethernet port! Can I send packets into my DVI port?
...No.
Seriously, why would I want to participate in this?

My packets have spoof all over them ! Anyone have a tissue?
This took out my wireless network on XP Home SP2 using Microsoft's wireless zero configuration tool for the software side of it. During the spoof portion of the test, all network connectivity halted and immediately reported that the wireless connection had disconnected.

...you can use a network packet monitor, and there's two ways to get your hands on such a device - the cheap...and the expensive way, the expensive way being the safest one (A hardware network monitor = hardware device to look and monitor what's going in/out of your ethernet connection directly connected to your "whatever" device)
or
Do the same thing by rigging a second computer, also known as a network monitor. Set up a Linux box...and monitor & control all the ports & packets being delivered to your network, and if you do your homework - you will "know" if that application you just downloaded and executed...truly is honest...and "doesn't phone home...like E.T"... he he he..
Live and learn kids.
What this world is coming to - is for you and me to decide.
Nearly 5 years ago, the great and all knowing Steve Gibson predicted that the raw sockets in Windows XP would allow packet spoofing that would bring down the internet with unstoppable DOS attacks.
So it must be true.
...every self-respecting network operator has RPF (or some other antispoof-ingressfilter) enabled at the edge. Gone are the days of spoofing, just like respecting IP packet's loose/strict source routing options and other similar exploits :)

The questions is not can an IP be spoofed (yes, it can always be spoofed from somewhere), but rather from where can it be spoofed and to where can it be spoofed to. You can spoof any IP address to another box on your local ethernet segment -- there are no routers en route that can drop the packet. You probably cannot spoof an IP to someone on the other side of the world, but your ISP or your ISP's ISP can. In fact, you can spoof any IP to almost everywhere if you have a connection to one of the few core Internet routers.
The project basically is saying that home users cannot spoof IPs to their measurement server. That's well and good, but useless.
Home users no longer need to spoof IPs to hide the source of the attack (as in days past). Home users now are simply trojan/zombie boxes that are hiding the true source of the attack by using their own IP -- no spoofing required. Back when zombies were not a problem, attackers used spoofing to hide their true location; it is no longer required now that boxes can be 0wned with relative ease.
I don't see the point of this project.
...the other 20% of spoofable IP addresses are reported to be in the possession of Weird Al Yankovic, who, according to US Attorney General Alberto R. Gonzales, is capable of spoofing damn near anything.
A full-blown investigation is under way to put an end to Weird Al's wild spoofing. Rap legend Coolio has pledged his support in these investigations.
Weird Al was unavailable for comment, but his assistant did pass along his official response, which was, "Mecha lecha hi, Mecha hiny hiny ho."

Yes, but how many of those are unique IPs?
What?

On *nix systems, you must run the spoofer as root (in order to create
the raw socket) with no arguments, e.g.

Ahahahahahahah! You're kidding, right?
You are checking your backups, aren't you?
