Yahoo Id's logged in Thru IP Address

[vinu070in]

Anyone can tell me if it si possible to know which all Yahoo Id's are logged in from a particular IP Address (if it is known).

Is there a tool for this

See Yahoo FAQ #3 for information on how to reveal a users IP.

If a user ID is added to your friends list on Yahoo! Messenger, yes it is perfectly possible to log the IP address of the computer logged in to the Yahoo! Messenger service. It is as easy as any program based on peer 2 peer technology over the internet. Your best bet to avoid having an IP logged from a malicious user over Yahoo! Messenger is never to add user ID's to your friends list of people you don't *really* know, who may have evil intentions to log an IP address, and to ultimately compromise your computers security.

I think what you are asking is, if you know the IP address, can you find out all yahoo ID's that log on from that address, right?

There are ways to get an IP address if you know the users yahoo ID. But I am pretty sure there's no way to figure out a user's Yahoo ID or ID's when all you know is their IP address. Somebody correct me if I am wrong. Hope this answers your question.

also the original question was NOT how to obtain an IP address from a yahoo ID, vinu070in asked if you can find the yahoo ID's that are logged in from a particular IP address if it is known.

Obviously. A Yahoo! ID is just a mask of an IP address. Yahoo! employees can lookup any ID (or IP address) and get a list of IP addresses (or Yahoo! ID's) that user has used to cookie his or hers ID (or IP addresses). Yahoo! consumers have no legitimate use for having this information, and is not a supported feature for Yahoo! consumers on Yahoo! network. No hackers have ever discovered a vulnerability or exploit to obtain such information. Its purely information a Yahoo! employee would ever need.

If it was ever possible for a hacker, they would need to get an IP from a Yahoo! service, they would need to reverse engineer something, in some way. Everything is possible, I suppose. Although this IP to Yahoo! ID is very unlikely to ever be possible at the frontyard. A hacker would need to break into a backyard network, essentially.

some told me that there are bots, created by hackers, that can check to see if a buddy is online without being logged into yahoo, and if the buddy,has more than one name, it will show all of them except if the names the buddy uses are logged on seperatly. Could just be rumor though.

- You need to be logged onto your friends list on Yahoo! Messenger network to know the online status, if the user is masking online status from the public. If a user hasn't choosn to mask his or hers online status, then its just a case of checking the online status of any ID, by for example, viewing the users profile.

- Yeah, the second part of what you are saying is true. Methods are available, which I won't disclose here, which can allow a malicious user to know all ID's on a parented account, and therefore, you can also check online status of these, by checking online status, by for example, viewing a users profile.

I take it you know about unsakred's Buddyspy? That program has the obvious flaws in privacy and security for Yahoo! consumers, that means Yahoo! Messenger team will need to build a brand new protocol in 2005 to sort all the concerns out, the program highlights. The program "Buddyspy", though has also highlighted less apparent flaws in the messenger protocol ver 12, which can't be seen by the untrained eye, but if you have an eye for this stuff, like I do, you'll soon get see more than meets the eye, where a hacker would be able to further exploit unsakred's proof of concept for online status checking. Basically, unsakred's program has drawn the attention to other pitfalls, not fully featured on unsakred's program, but yeah.
