Skype outage last 24 hours

If you are a Skype user, you may have noticed trouble logging in. At first I assumed this was a problem at my end as my colleagues seemed to be still using Skype all ok.

Then I see the outage page on Skype - here - saying its a software problem. Fair enough.

Then we see a Proof of Concept for a DoS on Skype - here - do we have to assume the 2 are related?

DoS's are quite funny, in that they generally achieve very little other than pain for the users. Sure there is a security problem with Skype's servers... but is there really any need to take the servers out for all users? I fail to see how the russians could make any money from this, as I doubt Skype will respond to any ransom demands.

Time will tell.

Just realised people are linking to this post - and I've not put any reference to where I got the PoC from - thanks to Valery Marchuk for posting information on Full Disclosure (not writing the PoC just informing)

Is it good etiquette to edit posts, I don't know, I'm new at this :)

Someone called ASCII has just rubbished the PoC mentioned above on the Full Disclosure mailing list here.

Also someone mentioned on another blog somewhere (sorry I forgot where) that there are rumours that MS broke Skype with their patches. Interesting theory if you like to bash MS all the time.

If we trust Acsii then Skype must indeed be having software problems, just an interesting co-incidence? As I said earlier, time will tell :)
