CNET | Interview, Andrew 'Bunnie' Huang - DMCA, XBox Hacking, Silenced Researchers
Topic: Computer Security 4:33 am EDT, Apr 16, 2003

] Taking a break from working on his doctoral thesis,
] Massachusetts Institute of Technology (MIT) graduate
] student Andrew "Bunnie" Huang decided that it might
] be fun to poke around the security systems protecting
] Microsoft's Xbox game console.

] I want to put a stake in the ground and say, "Hey, I
] strongly believe what I'm doing is legal and it's
] beneficial for people to know about this stuff." If we
] don't know about it, then the bad guys are going to
] figure it out and they're going to take our lunch. Maybe
] I'm being a fool by saying this, but if someone wants to
] challenge me on this, I think it's something we need to
] talk about in a court of law. I don't know where I'd find
] the resources to defend myself. If I am taken to court,
] then I'll figure it out.

] There are things that they can try. But there's a dozen
] attacks that I've kept in my back pocket and that other
] hackers have kept in their back pockets that nobody's
] even talked about. Those will come out if Microsoft
] tries to secure the hardware again.

He also talks about his book on XBox technology, which he is having trouble publishing due to book publishers being scared to death about the DMCA. Many good quotes within..

On the Economics of Anonymity [PDF]
Topic: Computer Security 2:30 pm EST, Apr  3, 2003

Decentralized anonymity infrastructures are still not in wide use today.

While there are technical barriers to a secure robust design, our lack of understanding of the incentives to participate in such systems remains a major roadblock.

Here we present new insights about how to align incentives to create an economically workable system for both users and infrastructure operators.

We explore some reasons why anonymity systems are particularly hard to deploy, enumerate the incentives to participate either as senders or also as nodes, and build a general model to describe the effects of these incentives.

We then describe and justify some simplifying assumptions to make the model manageable, and compare optimal strategies for participants based on a variety of scenarios.

This paper was presented at Financial Cryptography 2003. Authors are from UCB, MIT, and NRL.

Admins take note.. Leaving your server-status open is lame. Leaving your server-status open when you have extended status on, is really lame. Want to see who is browsing www.nbc.com? No problem! Just a little information leakage..

I hit reload a bunch of times watching for the Restart Time and PSG to change, as that would indicate a different server in a SLB rotation. I only saw two machines. I also noticed that the Server Build time changed, which indicates that they do not compile their binaries on a seperate machine and use some package management scheme to manage the software on the boxes. Sloppy.. Sort of like leaving your server-status open for the world to see.

As a side note, you can go to Google and search for "Apache Server Status for" and find many of these.. Although at this one, you will actually see some serious traffic taking place.

Wonder how long before this gets closed..

FYI NBC, in httpd.conf:

&lt Location /server-status&gt
SetHandler server-status
Order deny,allow
Deny from all # Or you could just use
Allow from all # these to limit by network
AuthType Basic
AuthName "Some AuthName"
AuthUserFile /some/place/where/you/have/a/htpasswd
Require valid-user

Unleashing the dogs of cyber-war on Iraq!
Topic: Computer Security 5:41 pm EST, Mar  6, 2003

But there are few means around the government's blockades of "objectionable" Web content, which, besides porn, includes domain registration sites, according to Heider Sati, an Al-Mansour graduate now running his own London-based IT consulting firm. The restriction, perhaps designed to muzzle protest speech, means Iraqis are unable to register and create their own Web sites. (Sati says he registered and hosts alMansourCollege.net, on behalf of his alma mater, for free.)

Despite these limitations, some of Iraq's geeks say they would suffer if the country lost its Internet connection, whether due to conventional bombs or cyber-attacks.

"[It's] just like having drugs," said Al-Shalchi of his dependence on e-mail and Web access.

Despite not even getting access to the internet until 2000, their geeks are just as addicted to a "net fix" as we are. Interesting article on the current state of connectivity in Iraq and the seemingly ludicrous idea that they could wage a cyber-war against us.
