Why I think FrSIRT officialy sucks.

So, you may remember that I posted a week or so ago about FrSIRT going to a paid subscription model, and that I promised to take an unbiased look at the new FrSIRT VNS (pay) service, through the 14 free trial. I signed up right away, and I've got one day left with the trial. 13 days was about 12 days more than I needed to see that it was not worth my money.

I signed in with my trial ID and password, and proceeded to step through the "wizard" on setting up my notifications, how I'd like to recieve them, etc. I set up that I want to recieve all notifications (not just systems that affect my environment), because that's how I keep abreast of all of the vulnerabilities and exploits - a good pen tester has a cache of exploits for just about everything, or at least knows where to find them. So, in my opinion the flitering of alerts is way cool, and I can see the value (although not for me). So far, so good.

Next, I selected the delivery method. Plaintext e-mail for me thanks! PDFs and a few other options were available, but I'm a simple guy. Again, I can see the value here as well, and plaintext works just fine for me (just as it always has). Again, so far so good.

FrSIRT also assigned my own personal RSS feed for the items I selected. Cool. I like.

Now to the REALY value for me. Exploits. Would I like to recieve notifications on new exploits! I sure would! As fate would have it, guess what is not available to trial members. Yup, you guessed it; exploits. This is where it turns bad, real fast.

Now, the FrSIRT folks, via their e-mails, promised that the trial account would let me see the value of the VNS service. Sure, I can see it, I'm just not allowed to use it. It is clear that it does have something to do with the new French laws, that apparently state that I have to pay to see. Clearly I haven't paid , so by law I can't seel. I'm all for being law abiding, even theough I realy do want to see.

Now here is the kicker: All of those features that they promised, you know the free ones with the trial account? Vulernerability reporting, right. Guess what doesn't work? Yup. RSS feed empty. E-mails? None. yes, I checked my junk mail. And my spam filter. And my Anti-virus gateway too. Nothing.

I don't care who you are, that's suckage right there (with all dure respect to Larry the Cable Guy).

Maybe I did something wrong.

However, I have noticed that milw0rm and SecurityFocus have increased thier coverage of exploits, and for that I thank them. Sounds like great alternative to me.

Vuln: FreeRADIUS Multiple Remote Vulnerabilities

Now I wouldn't normally post something like this, but I thougth it was valuable due to some research that Paul and I have been doing - specifically regarding tinyPEAP (a third party firmware for the Linksys WRT54G).

The tinyPEAP progect uses FreeRADIUS for the radius server in the firmware, which is a great way to implement WPA-Enterprise on the WRT54G, in one standalone box. The problem is, I can't find anywhere on the tinyPEAP webpage, or in the forums, what version of FreeRADIUS thier implementation is based on. Given that the last release of tinyPEAP was on 4/9/05, I can't imagine that it is terribly new, and is more than likeley vulnerable to all of the remote attacks described in the advisory.

At this point, I'd have to advise against the use of tinyPEAP, until It can be confirmed that thier implementation of FreeRADIUS is not vulnerable. I'd suggest looking at OpenWRT instead, as I believe that they have an implementation of radius as well - and if they use a vulnerable version, you can put money on it that they will update it ASAP - the OpenWRT project is activley maintained, and under active development.

Ophcrack 2.2 Password Cracker Released

I think that this may be a little bit older news, but I think that it was relatively timely.

Since I just learned last week that L0phtcrack has been discontinued, it is time to look for alternatives. Ophcrack is certainly one of the alternatives. I haven't used it yet, but I am going to look at it over the next few days.

Configuring a free VPN solution in your home

EGAD! XP as a VPN server? Using PPTP? I don't think so.

Go for hamachi instead. Hamachi uses proven, secure technologoes (not that PPTP isn't proven, but it certainly isn't secure especialy when using MSCHAP for authentication, such as windows XP).

1. Inform the readers. They need to be safe.

2. Stop picking on Mr. Schneier. Go find bugs in Steve Gibson's work instead.

Bugtraq: Cisco Aironet 1300 DoS condition

I had this filed away earlier this week, but lost it in the mass of news feeds.

Cisco AP 1300's running ISO 12.3.(8)JA in default configurations are easy targets for DoS attacks, effectively rendering the devices unreachable. Apparently Ciso advises against running IGMP Snooping and WiFi Multimedia on the device at the same time, as they claim it will cause degradation of service. Apparently what Cisco failed to note the severity of the degradation of service (total), and that these two oprions are turned on by default!

Oops.

Now, it is not apparent to me from the advisory how the DoS is set off, but maybe that is just me being stupid...

Brief: Web site takes exploits private

Ok, some more explanation from FrSIRT on why they went to a subscription based model.

Apparently the French government has been putting pressure on them regarding some new laws on computer exploits, so in order to comply with the law they had to move to a subscription based model, which they claim they do not intend to profit from.

I call shenannigans

First, if that was the case, why was it such a big secret? FrSIRT could have said that they were doing this because they needed to be law abiding. That's cool, and I would respect that, bit to not put any reasoning out there until they were called on it is a load of crap. I don't respect that.

Second, If they are not intending to make a profit from it, why does it cost $4500 USD a year per person? It seems that they were giving it up for free for a long time as K-otik and as FrSIRT. So why not comply with the laws as a subscription for a token amount (say$10 USD per year)? Seems like it was the first rock of crack for free to me - now that I'm hooked, I gots to pay. Sure, you could argue that the new service is offering more, and is customizeable and so on, but to me it is not worth it.

Now that being said, I just got my 14 day trial to check out the new features (after far more than the 72 hours as indicated), so I will really be able to make up my mind if the new features can justify the cost. I'm going to give it an open mind, and be sure to post here when I have a full impression.

March Microsoft Security Bulletins Released, (Wed, Mar 15th) id1190

Time get patching, windows guys and gals.

MS06-012: Critical exploit that could allow arbitrary code to be run on a windows system as the user when opening malformed documents with any MS Office product. The important thing with this one is that Proof of Concept code is already public.

MS06-013: Important Windows privilege escalation. This one could be used in conjunction as the PoC's for MS06-012 to gain full control of the system. Sure it is possible that other privilege escalation techniques could be used, but this one is new, and attackers would most likely find this one unpatched if they were to move quickly.

Break out those fingerprint sniffers!

Microsoft's fingerprint reader sends fingerprints from the device to the PC unencrypted, which sould be sniffed in transit. The vendor says that encryption is available on the device, but it appears to have been disabled by Microsoft.

'Keylogger text' spooks Symantec

I had to get a chuckle out of this one.

Norton Firewall and Norton Internet Security users, get bumped from IRC when someone in a channel they are participating in types "startkeylogger" or "stopkeylogger", which the Norton software interprets as a botnet client. It is good to know that the product does work, but it will be great fin to try out the next time you are on IRC to see who is using those Norton products. Can you say "information disclosure"?

Symantec promises a fix soon.

Fedex Kinko's smart cards hacked

This is an awesome video of the guys from Secure Sciences Corporation doing a demo of the Fedex Kinkos smartcard hack.

Apparently, Fedex Kinkos tried to deny that this was possible, and now states that it is no harm to the users. Wile I agree that it probably poses no harm to the users, it could certainly harm Fedex Kinkos. Clearly it is possible, contrary to what Fedex Kinkos claims.

Now, smartcard hacking is not a new thing. The satellite folks have been doing this type of thing for years. However the challenge becomes finding the correct code, and applying patches in an extremely small memory space. Apparently the Fedex Kinkos deal is a total no brainer.

Remember, stealing satellite TV, and forging Fedex Kinkos smart cards and claiming a refund could be construed as fraud. That being said, there is a Fedex Kinkos right down the street. I might go pick up a few cards to check out and see how they work.

Fedex Kinko's smart cards hacked

fedex kinkos express card

Researchers at Secure Science Corporation have managed tobreak the ExpressPay system used atFedEx Kinko’s stores which is provided by enTrac. The cards are write protected using a 3 byte security code. You cansniff this data using a logic analyzer and then use the code to write any data you want to the card since it isunencrypted. The security code is the same across all cards. FedEx Kinko’s stated that the article is inaccurate, soLance James and Strom Carlson made a video ofthemselves doing the hack in the store: They purchase a card for $1.00 from the kiosk and then use it to log into acomputer and show the balance of $1.00. They logout and use a separate laptop and card reader/writer to change thebalance to $50.00 and modify the serial number. Next they use the card to log back into a computer and show the balanceof $50.00. They let one minute pass so that $0.20 is charge to the card. Finally they logout and use the self-servicekiosk to print out a receipt showing their balance of $49.80 with the fake serial number. At this point the attackercan take the card to the service counter and ask for the balance in cash.

An Assignment From Professor Packetslinger of the School of Loose Screws, (Wed, Mar 1st)

I agree with everything that the fine handlers over at the ISC has said.

It appears that "Professor Packetslinger" has asked "his" students as part of an assignment to perform a pen-test against a machine across the internet. No mention of previous permission is mentioned, which is bad.

So, if the students complete the assignment as directed, they are breaking the law. It would also seem that the professor, by coercing the students to break the law, is an accessory. The yet un-named university will not intervene with the professor, but will refer students who scan university systems to the appropriate university authorities. Now, that my friends, is screwed up.

The moral of the story:

Always get permission.

Paranoid? I think not. Safe? I'm sure.

Thier setup is fairly unique with the level of security that they have implmented. To me, this offers some precious insight on things thay you may want to consider for your own data centers, and disaster recover sites. Now depending on your risk, the security measures may be signifiganly less, and require less security, but the same basic concepts are the same:

  • Physical security
  • Power availablilty
  • Protection from electromagnetic attacks
  • Redundant paths for data and utilities
