Skype IP Lookup
- zhovner 14y agoIt is work for you?
- tibbon 14y agoYep. Tested myself and a few remote coworkers.
- bryanlarsen 14y agoPlease don't downvote this. This is the actual developer asking for failure reports etc. English is not his first language, either, so please don't downvote because of brevity or poor grammar, either.
- artursapek 14y agoEnglish may not be his first language but he seems to know the basics. http://i.imgur.com/ADxK3.jpg http://i.imgur.com/ADxK3.jpg
- lis 14y agoI tried, but the server seems to be busy? I am not getting a result.
- daeken 14y agoI just tried it and it didn't work. After maybe 5 minutes of "Please Wait...", it said no results found. Is it just overloaded?
- orta 14y agoYes, worked great for me! crazy
- nextstep 14y agoYeah, I just entered a friend's skype name and it showed an IP in correct country and city
- gmcabrita 14y agoWorked fine here.
- 5vforest 14y agoYes, it worked perfectly.
- rorrr 14y agoYes, it worked
- pandog 14y agoWorked for me - and with a quick reverse lookup I was able to tell a friend the name of his halls of residence
- ohashi 14y agoNot working for me. Do I need something installed?
- OzzyB 14y agoCookies error MacOSX Lion, Safari [SP], Skype is installed and on, don't know what else I can tell you...
- tutre 14y agoit even show my local 192.168... weird BUT HOW?
- zhovner 14y agoSkype announce both your IP's into network.
- TazeTSchnitzel 14y agoPresumably for LAN efficiency? If you have two people on LAN using Skype it goes via LAN IP?
- zhovner 14y agoAlso if run several clients it shows them all.
- wib 14y agoSo if you keep several clients open in different places, it's at least harder to determine which IP reflects your current location, right?
- Juha 14y agoThat's scary if they really show the local IP. It becomes quite handy tool for hackers. If they have breached any computer in a company network and want to target the CEO's computer next they can just use Skype to get his IP.
- alexchamberlain 14y agoReasonably impressive and scary.
- mcs 14y agoYeah, now you can obtain an IP by name by searching for their name in the contact search of skype to get the username, then using this tool.
- zhovner 14y agoSearch by email also work.
- mcs 14y agoThis isn't exactly patchable by skype, is it? Obviously skype could turn off some printfs from the log, but the fact the client needs the IPs and Ports to attempt connecting locally, and then over WAN, makes me think that a tool like this can exist forever.
- zhovner 14y agoOk, so I'm develop this. It based on deobfuscated Skypekit runtime that write clear debug log. Wrapper just make vcard refresh from p2p skype network and then parse debug log. Here is the sources of python wrapper https://github.com/zhovner/Skype-iplookup/ https://github.com/zhovner/Skype-iplookup/
- lobovkin 14y agoI have decided to post this link so not only Russians know about it :)
- zhovner 14y agoLol, skype banned my account.
- dennisgorelik 14y agoWhy banned?
- ashconnor 14y agoWhy do you think? This probably violates a few terms of use.
- bberrry 14y agoFrom just looking up the IP to that account?
- demonfly 14y agoI'm trying to start server.py on Ubuntu 12.04 (Python 2.6.7) but I receive this error starting server.py: Exception AttributeError: "SkypeKit instance has no attribute 'socket'" in <bound method SkypeKit.__del__ of <skypekit.SkypeKit instance at 0x117d7a0>> ignored Unable to create Skype instance Any idea to fix this problem?
- zhovner 14y agoYou must put server.py in ./skypekit-sdk_runtime-3.7.0/examples/python/tutorial/ and run out there. Also you need edit keypair.py Please create all issues on github.
- bemmu 14y agoCould you somehow scrape all users and get an IP address -> skype name mapping? You could then know the Skype usernames of all visitors to your website.
- zhovner 14y agoNo this not possible. Only skypename -> IP, and only email -> skypename. You can parse whole skype network and store all IP's if you can handle so many data.
- corin_ 14y agoThe geek part of me wants to do this / see this done, the part of me that oversees a few popular content sites thinks there isn't a huge amount of benefit to it. Even for malicious purposes, Skype is a very poor option for spamming. To creator: very impressive stuff, congrats.
- gitarr 14y agoWell this is scary for Skype users and very embarrassing for Skype developers/owners aka. Microsoft. I sure hope they fix this before they get sued into oblivion for this blatant privacy breach.
- alexchamberlain 14y agoFair point, but equally Skype was an independent company when it developed its protocol, and although Microsoft hasn't fixed it, its not really their fault.
- gitarr 14y agoIt might not be their fault, but it sure is their responsibility now.
- sohn 14y agoThis is the most stupid way I have ever seen to blame Microsoft for something. Bet you're a Mac user?
- viraptor 14y agoWhy is that? You get the same thing with emails / IRC / some IM protocols / VoIP. What's so "scary" about someone knowing your current IP? I mean - it's one thing if Skype was advertising itself as a privacy protecting, identity hiding service... but they don't. They provide convenient A/V connections.
- BystanderX 14y agoIt's scary when you think about the context - someone you haven't added to your contact list, meaning anyone at any time, can find your current IP. It's not exactly shocking, but it certainly shouldn't be able to happen until you've approved a person as a contact.
- rhplus 14y agoLet's say A wants to find B's IP address. In the case of email, A would need to trick B into replying to an email (and also use an email service that adds the client IP header). In the case of most IM servces, B would need to accept a friend request federated from a server. If I'm understanding this correctly, with Skype, A merely has to query B's status to get B's IP address.
- tdr 14y agoCan it be used like the invisible scanner for Yahoo Messenger? (see who's invisible)
- zhovner 14y agoNo, after disconnect it still show IP few hours
- antirez 14y agoUsing the IP is for instance possible to locate, roughly, where the user is, that is already a big privacy concern...
- revelation 14y agoSkype is P2P. No way to fix it, you can only hope to mitigate it.
- aw3c2 14y agohttp://skype-open-source.blogspot.de/2012/04/skype-user-ip-address-disclosure.html http://skype-open-source.blogspot.de/2012/04/skype-user-ip-a...
- hanbam 14y agoHere [1] is an interesting paper regarding P2P networks and privacy --- "Exploiting P2P Communications to Invade Users’ Privacy" [1] http://cis.poly.edu/~ross/papers/skypeIMC2011.pdf http://cis.poly.edu/~ross/papers/skypeIMC2011.pdf
- JohnnyFlash 14y agoReally scary. I wanted to see if i could find someone. Went onto twitch.tv. Picked a random stream. Got email. Looked up Skype id from email. Searched for skype id which gave me the IP and the small town where they currently reside. Its worrying how easy this makes it to find someone.
- TomGullen 14y agoHonest question, why is it scary? My IP resolves to a location ~20 miles away. I don't see why having a Skype contact and knowing a 20 mile radius where they live is anything to worry about?
- jeff18 14y agoMost residential internet connections don't have any sort of DDOS protection, so privacy issues aside, at the very least you are open to a simple denial-of-service attack. This was a huge problem for the popular progamer "Destiny" in the Starcraft 2 community.
- TomGullen 14y agoSo is it also really scary that the mods/admins on the Starcraft 2 forum could also see his IP address? The risk of being DDOSed when you share a contact on Skype and they find out your IP address is hyperbole.
- jeff18 14y agoThere is a pretty substantial difference between a few Blizzard employees knowing your IP address and the entire public knowing your IP address.
- junglhilt 14y agoYou obviously don't live in China...
- jQueryIsAwesome 14y ago
- option_greek 14y agoSomething worth 8.5 billion got to be a little more secure.
- sek 14y agoThat's why Google didn't bought Skype, their P2P is not state of the art. Your client is also a server for someone else, they obviously need your IP address and a proxy would not reduce traffic for Skype. Why the heck did MS pay so much for it?
- bdonlan 14y ago> Why the heck did MS pay so much for it? Skype has a huge userbase. They can always migrate that userbase to a different technology later if they think it's worth it.
- ajross 14y agoAny insights into the exploit? Obviously the bug here is that they got the IP without any confirmation from me; ideally Skype should be popping up the "new buddy request" dialog, but it's not. So is this a fixable leak, or something core to the protocol (i.e. do you request a buddy P2P too?)
- Wilya 14y agoSkype is at its core a p2p idea, so this is expectable. That's sort of the same thing that was done for bittorent users, except with a single centralized authority. The interesting thing is that they do this without making a call. They only request contact information. This could be avoided. Skype can mitigate this, but in the end, there is little more to be done. If you want a p2p network where anyone can be reached, at some point, you will need ips.
- corin_ 14y agoWhat they could do is have contact requests go through Skype master servers, not p2p, that way you could only look up the IPs of people you are connected to. But is it a big enough issue that they will make such a big change? I doubt it - and I'm not sure they ought to have to do it, either.
- Wilya 14y agoNote that you are not always forced to be in someone's contact list to contact him. It's a user configurable setting. I wonder if call-blocking for incoming calls from persons not in contact list is done at server level or client level.
- acqq 14y agoYes there would have to be master servers to close this hole, but I can't imagine how it can be done without everybody upgrading to the new client, so we can assume that every Skype user's ip is known or will soon be known. The current state will last for a while. You don't have to be even logged in for this to work(!) according to some already published research.
- tjoff 14y agoSkype sometimes routes calls through a third party. Even when calling you shouldn't be sure that the IP is that of the recipient or the third party. (The site doesn't work so I haven't read the article.)
- Mizza 14y agoNot sure why people are surprised by this.. what did you think P2P meant?
- aw3c2 14y agothat calls/communication would be p2p (direct connections) but not that looking up my nickname would disclose my current ip.
- vsviridov 14y agoCool, my router lacks decent DynDNS support, but I have skype signed in at home, so I can always check what my IP is and VNC myself in :D
- myared 14y agoIt's interesting that I can lookup people at my company who are behind the same connection that I am, but my account doesn't give away my IP. They also seem to get a lot more SPAM calls whereas I get fewer. I wonder if it's a privacy setting that I setup in the past or just the fact that my account is older. Either way, it's great to know that this is possible.
- AnonCIO 14y agoI am firing our security consultant for not telling us about this. Our entire organization is exposed. We have just learned that the man behind Skype is the same person who was behind Kazaa. And he knew this all along.
- dboat 14y agoI think you might be overreacting. The kazaa thing was kind of common knowledge. Unless your business is very unsavory, I don't think allowing skype to get in your office, like every other office in North America, is any great failing.
- steve918 14y agoOr maybe you could resign for being an uninformed CIO. P2P is 1990s technology.
- alan_cx 14y agoBack to pen and paper, copper wire and snail mail? Has its appeal I suppose.
- ilya2 14y agoOnce you have the IP, and an open UDP port, file sharing becomes a trivial extension. "P2P", "VOIP", "Skype", "File Sharing", whatever you want to call it. Bits are bits. A "file" is just an abstraction. All the same.
- ilya2 14y agothis is not an "exploit". as the man says, your IP is being sent out to the network. others on the network are using your machine's resources. that's how skype works. he's just showing you this fact.
- rjsamson 14y agoSo yeah, this has me more than a little perturbed. I generally don't have a problem sacrificing some privacy in return for functionality (the terms of service of several popular social networks come to mind), but this... is a bit of a different situation. Does anybody have a good short-list of Skype alternatives? I don't know that its possible for me to stop using it altogether, but I'd certainly consider cutting back...
- 18pfsmt 14y agoI would point you toward Jitsi: http://en.wikipedia.org/wiki/Jitsi http://en.wikipedia.org/wiki/Jitsi But, it doesn't support the Skype protocol, and it runs on Java, with which some people have an issue (but also allows for cross-platform compatibility).
- ilya2 14y agoshould be easy to do file sharing over skype when you have the receiver's ip and an open udp port through the firewall. maybe someone will release an app. can the mpaa sue microsoft?
- driverdan 14y agoIf you're not currently logged in it still discloses the last IP you used. I can't think of any good reason for it to do that.
- TazeTSchnitzel 14y agoIt doesn't work if you're not logged in.
- driverdan 14y agoI was logged out for over 5 hours when I tested it and it showed my IP.
