Then, using the 8e6 Enterprise Reporter, we took a look at the logs to see if we actually had users trying to contact the Triangle Boy network. We found that in the first 48 hours, users had gone to the primary Triangle Boy Website over 30 separate times."

    I can understand the concern that people have over Triangle Boy, but one must consider something important (in terms of the school in the article, anyway): Filters in schools are put in place primarily to prevent students from accidentally accessing some content that the parents may sue over. That, and to prevent kids from wasting their schooltime sending emails. However, to make use of the Triangle Boy, one must a) know how to use it, and b) have a specific reason for accessing blocked material. I don't see the liability issue there - its a piece of "stealth" software that the student, of his own free will, has used - despite acceptable measures to prevent he or she from doing so.

      Accidentally? Bull. If that were the case, then the filtering software would allow the student the option of immediately overriding it. If, say, a student were surfing Slashdot and accidentally clicked on a hidden porn link, they'd get a window explaining that the site is blocked for sexual content. Then they'd click a confirmation button (or even have to type out "allow site" to prevent accidental clicks), and they'd be able to surf the site. But that's not how it works.

    Clever users will also note that you can tunnel this over just about any port you want. Make this an encrypted tunnel and no filter in the world will detect it. If your school/network allows even a single TCP port out to the Internet you can do this. (Some places allow arbitrary TCP ports to be forwarded via the HTTP proxy. Other places may have a SOCKS or similar proxy available. Those would both work for this in the event all direct connections are blocked.)

    According to this article it works by spoofing the the source address. I know at least my firewall would block that.

Now, unless they rely on word-of-mouth to tell people where those servers are, they would have to have one or more (easily blockable) servers to hand out IP-addresses and port numbers to connect to.

That windows let users install programs like triangle-boy without administrator privileges (or that administrators regularly give users administrator privileges).

      Unless I'm reading this wrong, or the author of the article doesn't know what they're talking about, the spoofing occurs outside of your network. Apparently, Triangle Boy knows that Safeweb IP addresses will be blocked by some firewalls or filtering software, so the return traffic from Safeweb (e.g. viewing web pages) is spoofed to the IP address of the Triangle Boy host. It's not like clients inside your network are spoofing their source addresses. If that were the case, you would be right and any decent firewall ruleset would block such activity.

      Your firewall would block address spoofing from the inside, but not from the outside like in this case.

    I personally have been in a University which performed heavy filtering, and even worked in the IT department of the school. I do not have a problem with blocking or lowering priority for certain p2p apps such as Napster (back in the day), kazaa, etc. I do however have a major problem with filtering web access. While p2p is a major problem in terms of bandwidth and is clearly not for academic purposes (the vast majority of the time), many blocked websites are quite useful for academic purposes. As an example, my school blocked the Google cache and pretty much all translation sites, because they could be "used to access pornographic content" (not neccessarily images). It seems that the possible benefits of said cache (which include pdf -> html and .doc -> html converters) and benefits of all the translation software massively outweigh the possible use for reading pornographic content. I must say, I welcome all such apps as triangle boy and hope to see them spread more widely, as it appears that is the only way we will keep the internet a place where information flows freely, without restrictions from those who would love to brainwash the masses. May Triangle Boy, Peekabooty, and any other similar projects flourish.

    This ought to be so simple - do not allow users to have sufficient priviledges to install software!

    Problem solved.

    Okay, before I get flamed, this won't work for developer teams or your admins - for whom I merely suggest you can implement a draconian contract - i.e. fire anyone using any software not explicitly authorised (a minimum policy imo) and have a regular *external* audit.

    Neither will this work for networks of Win9x clients, because you can't set appropriate secuirity policies. However you could always get SMS from M$$$$ or write your own scripts to call registry entries and check them against a permitted template so as to flag suspicious installations. At the end of the day it may even be worth upgrading your clients. Or just installing Linux and StarOffice, if you can, he he :). But with respect to upgrading even say from Win9x to Win2k, which ain't cheap, it's still probably less expensive than all the FUD claims - even the reality - of lost security and lost productivity from unauthorised use of your network resources and manpower.
