Skype Journal: Skype Passwords Compromised?

November 30, 2005 08:53 AM

skypecompromised.pngI just received the following scary notice from Skype (Full text below). It suggests that Skype passwords for some users --- at least those that had also logged in at share.skype.com the Skype Corporate blog have had their Skype passwords and thus their SkypeOut account access compromised.

Thanks to Kurt Sauer, head of Skype Security for clarifying:
  1. Fewer than 1% of Skype users were affected
  2. Only users who'd registered on the Share.Skype blog
  3. This was a routine upgrade, not a response to a data leak
You can read Mr. Sauer's full remarks in the comments to this post.
This is a very serious matter and a breach that many security experts have warned about. I remember when share.skype.com launched expressing my concerns (and also the benefits) for using Skype names in capturing comments with the community in the blog format. I was surprised they 1)could do it and 2)felt uneasy that I'd be using this password each time I logged in.

If your Skype name is compromised you will be notified by an email. I would like all readers who have a compromised account to leave a comment on this blog. I'd also like to hear from anyone that gets this email that has never logged into share.skype.com. I also wonder if this "process" is going on further behind the scenes. My guess is that many Skype ID's that have no current e-mail address are going to be lost by users. Having just replenished my SkypeOut account yesterday, my email was reverified and terms represented. I may have to test the other 20+ names I hold see if they tell me anything.

Remember. You must change the password that is sent to you. It is sent to you in an unencrypted e-mail. So to be safe you must go to Skype and change it again. Don't change it back to your old password. This means users must change their password twice. Potentially anyone scanning e-mail traffic for the phrase Skype password will get your user name and password and have a field day capturing perhaps millions of user accounts. How big is this? We don't know. How many names were compromised? How many emails were sent?

By the way... some question is this a hoax.... it is not. See the Skype Forum. Where it is written "Your email address has not in anyway been comprimised or hacked." Nope. share.skype.com didn't have access to your email address --- only your Skype password. Some have noted difficulty getting their new passwords. Apparently it may require some patience.

(Update: Tried to make a SkypeOut call. My Skype was closed and I am now without a password having followed their instructions. So much for business!)

Dear share.skype.com user,

We are upgrading share.skype.com so that the system used to sign in to the site is better integrated with the main Skype.com user sign-in system. You used your Skype Name and password to sign in to share.skype.com previously to participate in discussions and use personalized content, and you will continue to do so.

Because of changes in the secure password storage system, we would like all share.skype.com users to update their Skype password to ensure their continued privacy.

During the next 24 hours, we will be resetting the passwords of all affected Skype Names. In order to sign in to Skype the first time after this reset, you should simply follow the procedures for recovering a lost password. Just go here and follow the instructions: http://www.skype.com/go/forgotpassword

Remember that Skype will never contact you to ask for your password.

WHAT DO I NEED TO DO?

Just go here to get your new Skype password: http://www.skype.com/go/forgotpassword

If you have trouble getting it from there, please
submit a Customer Service ticket at this address: http://support.skype.com

Alternatively, you can e-mail to support 'at' skype.net, to reset your password.

HOW DO I KNOW THIS E-MAIL IS NOT FAKE?

We have recently seen a lot of Skype-related faked e-mail. You should always be careful about such e-mails. Remember, Skype will never contact you to ask for your password. To show you that this e-mail is valid and from Skype, a copy of this mail is posted at the following
address: http://share.skype.com/share.skype.com_upgrade_and_your_skype_password_change/


Skype. The whole world can talk for free.

DON'T WANT TO HEAR FROM US AGAIN?

We don't want to send emails you don't want to receive, so please remember that you can just send an empty e-mail to the following address and we will never bother you again: mailto:unsubscribe-XXXXXXXXXXX@news.skype.com

Hello. My friend has just lost his password. He can't log on skype anymore. Unfortunately he had some money on skypout. Don't wait. Also he can't remember if he ever loged on share.skype.com so risk is even bigger.

I got the same e-mail for my main Skype account! Ididn't receive other e-mails for other accounts i have (i only registered with my main account name on the "share Skype" blog. I agree this is a big nuisance and scary :-( , although they try to reassure!
I am indeed angry! And you are right: those who didn't register with an e-mail address, or who "lost" the e-mail address for any reason (e-mail account cancelled for instance) will also lose the username and credit! Unless Skype has a solution for this!

Posted by: Jean Mercier at November 30, 2005 10:25 AM

I got the same email from Skype. And until I read this post, didn't really look at it. When I read this, I hurried over and changed my password but the the promised new password hasn't arrived. Am afraid to log off Skype as I will be stuck. Hope my SkypeIn and SkypeOut credit doesn't vanish. This is nuts. Skype is probably overwhelmed by the number of requests and hasn't been able to respond to all ... am hoping.

Why some users got a password change

Skype has a standard for storing all Skype user credentials and we've just completed an audit our platforms to make sure that all systems meet that standard. One of the elements of this standard is that all user password authentication must be done by a central system that employs a single uniform password encryption and storage methodology.

If any of our service platforms want to use Skype usernames as the basis for identity, they must use that central authentication system. By using the central system, we believe that we can best protect our users' privacy.

Our audit showed that the only one system in our services infrastructure stored encrypted user passwords outside of our core authentication system, and this was the "share" site. The "share" site stored encrypted user passwords, too, but should have used the central system to do all authentication.

However, because passwords for users of the "share" site were stored in a different encrypted format than that which we set as our standard, I directed our operations team to eliminate the parallel storing of encrypted passwords, to consolidate the authentication systems, and to require users to change their passwords to ensure that stored passwords are always stored securely.

As of this morning (30 November 2005), we had consolidated all authentication in one place and eliminated the parallel storing of encrypted passwords. With that task completed, we then began the process of notifying users and requiring password changes for users.

How we're dealing with the problems

The password changes affect less than 1% of Skype's registered users and its implementation enhances the security of Skype users and of Skype's service offerings. But we know that some users have had problems resetting their passwords as a result of this authentication migration. Our customer service team (http://support.skype.com) is aware of these issues and stands ready to assist people who have had these kinds of problems.

Because of this experience, as well as suggestions received by users, we are working on a number of longer-term solutions to make password management better and more robust.

Every service has to do this now and then. What bothers me is the way they did it. I was blindsided.

I received a SkypeIn voicemail last night (from the UK while I was sleeping in California). I clicked to return the call and Skype killed my 15 open chats, logged me out. I missed a scheduled press interview, and connecting with various team members because of this lockout. I was at the gate to Skypeland for an hour. Frustrating. And scary like you said.

Posted by: Phil Wolff at November 30, 2005 11:03 AM

I got locked out too, had to request a new password

Posted by: Paul Jardine at November 30, 2005 11:06 AM

Interesting analysis, but I'd be surprised if Skype/eBay would try and cover up a security breach as they'd be sure to be found out eventually and get a lot of bad press on it.

Have you contacted Skype for comment?

Is it safe to choose my old password again?

Damn being an alpha tech geeky user - I had to go through the saga this morning....annoyed

Posted by: Mike Hayes at November 30, 2005 11:54 AM

This is exactly the type of issue that makes Security Consultants like myself cringe and what make enterprise security people say "See Skype is clueless about security". This is the WORST mistake a company like Skype can make.

The general rule of thumb for this sort of need to update personal information of any kind or any information about a users account is to follow the following rules:

1. NEVER ever place a URL in an email - this practice of URL's in email whenever you are asked for anything personal is why issues like Phishing cause so many loses for companies. The practice should be to just say "Go to our website directly and update your information". "We do not put URL's in emails like these so that you know you are going to the correct site and to protect your privacy." "Any emails from Skype with URL's in them that ask you to update your information should be considered BOGUS!."

2. Any emails with URL's in them that ask you to update ANYTHING about yourself should be considered malicious and deleted.

3. NEVER ever send a username AND a password in the same email - EVER!!!!!!! send two emails and even better at different times or days. Make the hackers work at it - don't give it to them on a silver platter.

Bad Bad Skype and "Hey eBay... you know better than this... Verisign and Pay Pal need to hold a Security Workshop with you on this.

Kurt,
Thanks for your detailed answer. It seems to put things at rest. I hope next time the communication is a little more effective.

From my perspective, I just wanted to provide the user response. Gut feel reaction to the message and getting kicked off Skype. I was not alone.

Posted by: Stuart [TypeKey Profile Page] at November 30, 2005 12:37 PM

Have been using Skype all day, restarting. Got a new password in minutes, everything went seamlessly.

Posted by: jyden at November 30, 2005 2:16 PM

I got the same message in e-mail, but have never logged onto share.skype.com, just www.skype.com. Ub fact, I've never heard of share.skype.com. I've used forum.skype.com, but use a username totally different from my Skype username.

My Two Cents Worth

Posted by: Goblin at November 30, 2005 2:33 PM

I got the email, too. And I have just checked, and sure enough, it refused to log me in. But who cares. I have switched to Gizmo, so I can use my regular phone with it even when my computer is turned off.

Posted by: Adam at November 30, 2005 2:58 PM

I too was unaware of ever having heard of share.skype.com, much less ever logging in or participating in a discussion. That the email posed and answered the question of how I would know this email was not a fake was in no way reassuring - we all know how dementedly devious these spammers and phishers are. Earth to Skype - most of us out here are not engineers and often don't understand what engineers are talking about. Whatever the security issues, Skype really need to hire a communications expert or two who understand how to communicate technical issues in a way that is both secure and gives confidence that the procedure explained is appropriate and not phishy. 0 out of 10 and I'm a big Skype fan.

Posted by: coachdes at November 30, 2005 4:23 PM

I don't recall ever using the share.skype.com but I too received the email and I'm locked out of skype now. Unfortunately, I use hotmail (big mistake) and have been waiting for 10 minutes to get the skype email with my password reset. Lessons learned are that skype is not quite prime time and hotmail sucks!

Posted by: Chuck at November 30, 2005 4:25 PM

I bit the bullet, went to the change password site, got the new pw in the email, logged back in without incident, then changed the password again and logged out and back in successfully. Now I'm breathing again.

Posted by: coachdes at November 30, 2005 4:32 PM

Appearently, I must have registered with Skype without an email. So my password has been changed, I didn't get any mail, and I can't reset it. Great... And I had SkypeOut credit that seems to have been stolen by Skype now. Not much fortunately. It was good that I only bought the minimum amount.
And yes, I have heard good things about Gizmo. I will definitely try to swtich if this doesn't work out.

Posted by: Tor at November 30, 2005 5:30 PM

Its been over 8 hours since I reset my password and I have not yet received the new password by email. I've also written to support separately. Am now locked out of Skype. What should I do?

Posted by: Dina Mehta at November 30, 2005 6:12 PM

hi, when will emails be sent to affected subscribers? i haven't receive one.

thanks a lot.

Posted by: eric_ at November 30, 2005 6:50 PM

No email received but when I tried to use SkypeOut it informed me my password had been reset. Apparently I did not have an email address in my profile so all is lost(?). I emailed support for advice.

Posted by: geomark at November 30, 2005 7:19 PM

What a bunch of idiots these Skype people. I am a Skype and SkypeOut user and I am so mad they would do this the way they went by it.

That email I received, looked so fake, I dismissed it.
Of course, I can not use my SkypeOut credit/ place calls.

Should heads should roll for this.

Posted by: Richard Franco at November 30, 2005 7:58 PM

Thanks for the heads up. Hope I am not a victim yet. I'm foolish enough to use the same password for everything. D'oh!

Posted by: Jonathan at November 30, 2005 8:13 PM

I have changed my new password to a revised one but I notice that the forum still requires the original one.

I thought the reason for renewing passwords was that Skype and share.skype forum would have an integrated server (presumably with the same password).

Posted by: wickham43 at December 1, 2005 12:44 AM

Yep like every body I was freaked by the email. Thought that it was a scam but checked the link, filled in my details and got the email with new PW within 2 mins, entered it and all ok. BUT as a PR stunt, what a huge stuff up - they should have warned people (if possible) unless a security breach was imminent. Ebay are going to be ropeable especially as other contenders to the Soft VOIP crown are lurking.

Update: I got a pretty quick response to my email to support, got my password reset, and I'm back in business again. I was surprised and annoyed at first. But I'm satisfied with the quick response.

Posted by: geomark at December 1, 2005 3:05 AM

Update - Skype support got in touch with me and asked for an alternative email id. Once I sent that, I got back in !

Posted by: Dina Mehta at December 1, 2005 3:53 AM

You say "Don't change the password back to the old one", is this really an issue if Skype are just saying they are integrating two separate servers. I'm no techie and was fairly confused by the email and the experience of renewing passwords etc.

Not very clear from Skype at all.

Posted by: mspoke at December 1, 2005 6:58 AM

I just found I had to "renew" my password; got the email very quickly and the correct SkypeOut balance was there when I logged in. A very mild hassle in the end.

Posted by: Jim Courtney at December 1, 2005 11:38 AM

Got the mail - clicked the link - entered e-mail address - clicked submit - NOTHING.
Waiting since hours.
This is unaccepteable business and I will terminate using this service.

Posted by: Ferdinand at December 1, 2005 1:47 PM

I'm not able to get into Skype, and since I was a VERY early adopter who didn't want to give my e-mail address to a then-unknown company, I cannot reset my passord. Looks like that username is now dead, along with the 9 Euros of SkypeOut credit I had.

Really, really bad move, Skype.

Posted by: Jellicle at December 1, 2005 3:58 PM

Mine was compromised also. But retrieved it successfully.

Posted by: ivan at December 2, 2005 2:49 AM

I also thought this message was a hoax, deleted it and told my friends to also do it.

Well, i was wrong about it, but thankfully we all could recover our passwords.

Posted by: Ralph Inselsbacher at December 2, 2005 3:27 AM

I got this message too, in the middle of a phone call and was promptly cut off. I tried to follow the route to the email address I had used for lost password as directed but that was rejected as not being valid. I am hoping that support will be able to send me a password, though the matter is not yet resolved.
I wonder whether it would be a good idea to look at VOIPcheap or some other supplier as at the moment skype does not feel secure or for that matter reliable. I confess that I am very reluctant to start over again and lose my credit through no fault of mine.

Posted by: J Taylor at December 2, 2005 10:51 AM

I'm really sure mine was used. But I moved house and broadband connection so the email can not be retrived. What the heck am I meant to do now?

Posted by: Ian Forrester at December 2, 2005 11:29 AM

Can't login too. Never registered an email so let's see what the ticket will give..

Posted by: s3ven at December 3, 2005 6:21 AM

I'd also like to hear from anyone that gets this email that has never logged into share.skype.com

I use SkypeOut and have never logged into share.skype.com. I don't believe Skype when they say everything is cool because a trace on the IP from that mail results in Doubleclick.

The other mails from Skype all have another IP which resolves to Skype.


Explain that, Skypemasters.

Posted by: brenda at December 3, 2005 8:28 AM

I got my password lost too. As long as I can recall I have never ever logged in the share site. I haven't received any mail from Skype nor I can reset my password through mail, as I didn't register any with them. I contacted support by mail 3 days ago, no answer yet. This an inexcusable mistake from Skype.

Posted by: Jose Miguel at December 4, 2005 1:30 AM

Mine was compromised also. But retrieved it successfully.

Posted by: ivan at December 4, 2005 5:56 PM

Compromised passwords is the inevitable consequence of how most service providers manage this information:

One of my accounts is locked out too. I can no longer get a new password as no mail address is registered for the account.

Posted by: Kaz at December 14, 2005 7:35 AM

Thank you for the blog. It's been a releaf to me)

Posted by: Alex at December 16, 2005 12:47 PM

I never used any Skype forums before today. I never got *any* email from Skype regarding the matter of compromised passwords. And yet, I was locked out of my account. That was in early December. I just got access to my account restored yesterday (Dec. 27) -- after nearly a month.

There's something fishy about what happened, and definitely something wrong with *how* Skype handled it. Completely unacceptable. They've obviously done a good job covering this whole mess up, however. I've heard virtually nothing about this outside of a few blog complaints (and if it affected "only about 1%" of Skype users, were talking about perhaps 100,000 or more screwed customers).

Posted by: Scott_H [TypeKey Profile Page] at December 28, 2005 6:32 AM


I lost my skype password since last two weeks
I woulkd like to use the same skype name because i have a lots of contacts in the same ID

Posted by: sonil26 at January 1, 2006 8:17 PM

When setting up name and password both got rolled into one long user name. They require seperating and re insertion.
Please tell me me how to do this !!! Ihave never sent any previous requests for assistance

Thanks John Brookie.
