Sean was one of many to pass along
the bad news
from the debian-announce mailing list: "Some Debian Project machines have been compromised. This is a very unfortunate incident to report about. Some Debian servers were found to have been compromised in the last 24 hours. The archive is not affected by this compromise! In particular the following machines have been affected: 'master' (Bug Tracking System), 'murphy' (mailing lists), 'gluck' (web, cvs), 'klecker' (security, non-us, web search, www-master). Some of these services are currently not available as the machines undergo close inspection. Some services have been moved to other machines (www.debian.org for example). The security archive will be verified from trusted sources before it
will become available again." They were going to announce 3.0r2 this morning; they've checked it and it's unaffected but obviously they're still postponing that release.

Then, have your password stolen, and oh shit, you're compromised. It's not about the OS being insecure, it's about a lost password. NOTHING can protect against this, short of one instance I heard where updates required 3 user passwords (from 3 users), but what a pain that would be.

As far as I understand, no machines apart from the several Debian computers have been compromised. Compromising a machine that hosts the central Debian APT repositories is a perfect opportunity for backdooring thousands of machines In this case, that didn't happen. "Thousands of machines across the globe" have not been compromised. I guess it's only good luck but Debian users were not affected by this security breach.

So there's no way this is a hoax ...unless the murphy.debian.org machine that emailed it to me is compromised, in which case it's not an inaccurate hoax :/

Nobody's asking you to trust the keyserver (Score:5, Informative)
(http://slashdot.org/)
PGP keyservers (unlike, say, Kerberos KDCs) are completely untrusted. Anyone can upload any key to a keyserver. And downloading a key from a keyserver implies nothing about that key.
To verify that you have a valid key, you have to rely on the web of trust. Basically, if a key is signed by someone whose key is signed by someone [recurse through however many levels you are comfortable with] whose key you have personally inspected, then the key can be assigned a trust metric based on how reliable you consider that chain of signatures to be. (Basically, how much you trust the integrity and acuity of the people controlling the chain of signatures.)
PGP and GnuPG have supported this infrastructure from Day 1. Asking people to trust an arbitrary third-party public keyserver was never in the plans.

Why should you? They were cracked. The bad thing has already happen, so there is no easy way out. However, there *is* a *right* way out. And that includes telling people what they know as quickly and effectively as they can. Too much information too early can be a bad thing.

At this point I would like to see the debian team develop some written policies and procedures for how they intend to prevent this sort of thing in the future. I checked the site and while there's security info for how to secure your box, there's no policies on 'how does the debian project secure itself'.
Lastly, one concept you have to keep in mind, we have no idea how often other OS's key servers are cracked because they'd never tell us.
A sign of things to come (Score:3, Insightful)
Open-source projects are not immune to attack and they are going to start feeling some of the pain experienced by other big targets like Microsoft. In the beginning it could be really bad because unless you're being attacked seriously all the time then you may not even realize where your vulnerabilities are.
This is a wake-up call to all "open" projects. Systems that are in use by a large number of people need to be protected better. Sure, this may have been a password compromise but the system should have been secure enough that some low-level user account compromise can't cause serious damage. And the high level accounts should never, ever have a password compromise. This needs to be treated in the same way big business does. Protect the customers, otherwise you may lose them.
This made me start thinking... Has Redhat ever been compromised? That'd be a reason for going with a commercial distro if the free distros can't get their act together. (I've been a Debian user for many years by the way)

People *already* know that OSS is not perfect, and they have known for years. People already know OSS is not immune.
But, more importantly, those same people know *nothing* is immune. Not MS, not Linux, not BSD, not (even!) MacOS, not DOS. *All* systems can be hacked.
What *really* matters is the attitude to security.
- A lot of the larger OSS projects care deeply about security. If a security bug is found, it's usually fixed very fast, and the fix will be peer reviewed.
- They openly admit all flaws and bugs. Because of this, OSS *appears* to have more bugs.
Do you see Microsoft admit all their bugs? I don't think so. MS hides a lot of bugs, pretending that they don't exist and that Windows is perfect.
Too bad all the MS zealots and anti-OSS/anti-Linux zealots use that to "proof" Windows is more secure than Linux/OSS/whatever. The number of bugs is *not* an accurate indication of security.
Linux zealots are only a small minority of the community. If you think they represent the entire community then you're wrong, just like so many people out there.

In case you haven't noticed, Slashdot has, and always has had, an editorial bias towards OSS, and against Microsoft. So do the bulk of the Slashdot readership. This is nothing new. This is a geek website, and the plain truth is, most people who call themselves geeks don't just sit blindy clicking away in Windows all the time. We like to play with our toys, we like experiment, we like to open it up and see what makes this baby tick. With something like Linux, you can do this. With Windows, you can't. Those are simply the facts. So of course people here will look upon OSS in a more favorable light.
Yet today, we have comments such as "hysterical ranting of the Debian wackos" being modded up as Insightful and Interesting? Hello people, that's called flaming. If it was more subtle, as yours is, it's called trolling. Walking into a Britney Spears fan club meeting and shouting "Britney SUCKS!!!" is also an example of trolling/flaming. So when you come to a website with an obvious and open slant towards something, and constantly try to point out that slant...
Well, I guess I just don't see why you're bothering. I mean really. If you really think the OSS community is full of shit, why on Earth do you come to one of their main websites/blogs/message boards/whatever?
As far as a double standard goes, I honestly don't get your point. Slashdot has never had a policy of reporting every single hack of a Windows-based system. However, pretty much every major OSS hole/exploit/hack gets a story here. Considering how many Windows machines there are in the world, you'd think there would be a lot MORE exploiting going on (hey, I'll use the "Linux would get hacked too if it was on 90% of computers" line for a change). And yet, we hear more often about Linux machines being compromised.
Well, except for things like Code Red/Nimda/Slammer/Blaster/etc, which, I'm sorry, but you'd have a hard time convincing me that this DOESN'T prove the case of Microsoft being just slightly less secure than Linux. Or else we'd be seeing Apache worms flooding the Internet on a daily basis, because "Microsoft only gets hacked because it's on 90% of computers", right?
Oh, and for the record, password compromises are OS-independant, and have nothing (read: zero) to do with the OS, design paradigm of the OS, colour of the developer's underwear, or whether we use a penguin or a flying box to represent ourselves. Only trolls would be saying "Ha ha ha ! Serves 'em right for running Bill Gates' Satanic OS. Let the jokes begin. Moderators, get ready !" if Microsoft had a machine get hacked because of a password compromise.
So what do we do to prevent this in the future? (Score:3, Interesting)
(http://homestarrunner.com/)
Simple, the technology has existed for decades now.
A little something I like to call "Public Key Cryptography"
With this "Public Key Cryptography" you could conceivably sign software in such a way that it could not be altered without breaking the signature, AND ensure that nobody else could forge this digital signature (you are keeping your private key private right?)
MD5 Hashes are a step in the right direction, but by themselves are meaningless. Sort of like improving your home's security by drilling holes in your door to mount a deadbolt but not actually taking the final step and INSTALLING THE DEADBOLT.
So let's take these MD5 hashes and encrypt them with the package maintainer's private key (or distribution maintainer, whatever). Then dpkg (or rpm, emerge, whatever your favorite package tool is) could be written to decrypt this hash with the corresponding public key. Wait, there is more! Then it could generate it's own MD5 hash of the package in question and COMPARE it to the decrypted hash it just created. If they match, the package is unaltered AND came from a trusted source. This my friends is what we like to call a "digital signature"
I don't care how you do it, GPG, x.509, whatever. I'm actually leaning toward x.509 since it seems to me to make more sense to have the distro maintainer run his/her own CA and issue certs to package maintainers. This CA could then be included in whatever package tool is used and viola. No mucking about with the web 'o trust (Which rocks for ad hoc trust relationships like between people emailing each other, but sucks for this kind of hierarchal stuff)
So what do you think everyone? Good idea or should we wait for a few more server compromises before we think about securing software repositories?

However, I hope this type of incident tempers the often-strident elitism of the free software camp. My faith in Debian continues because they caught this problem and openly announced it; my concern is that the lack of consequences will make people assume that this was a false alarm or unimportant incident.
Free software suffers from "victory disease" -- an assumption that, based on past success, future success is guaranteed. Because free software has proven reliable and secure, the concensus seems to be that it will always be so.
Pride comes before the fall, as they say. Attempted infiltrations of the Linux source code control system and breaches of security at Debian suggest that we need to be cautiously optimistic, not naively myopic.
