Part 2 - History The need for humans to communicate faster and more efficiently has been one of the
driving forces behind the Internet. Not since the invention of the telephone has communications
between humans been more readily available. The communication power of the Internet began to take
shape in its infancy with one of the first Internet applications, email. While the Internet was
still ARPANET and with only four links, the first email message was sent by Ray Tomlinson in 1971.
The first message consisted of the text “Testing 1-2-3” and did not contain any of th...

While Yahoo! was off fighting Microsoft, they made some deals with Google to put a slightly
tainted taste into the merger deal. The most notable one was an ad revenue “trial” where Google
would serve the ads on Yahoo! pages in return for a very favorable share of the profit. Over
the past week it appears that the trials were very successful and Yahoo! has agreed to a more
permanent deal with Google that would continue the deal, pending any anti-trust issues. Mixed up in
this agreement is a paragraph that indicates future interoperability between the two IM...

Over the past week the talks of Microsoft buying Yahoo! has not diminished. Recently Slahsdot
(http://tech.slashdot.org/article.pl?no_d2=1&sid=08/04/07/236215) published a note that points to
both a Microsoft press release
(http://www.microsoft.com/Presspass/press/2008/apr08/04-05LetterPR.mspx) and the Yahoo! reply
(http://yhoo.client.shareholder.com/press/releasedetail.cfm?ReleaseID=303369). The bottom line is
that Yahoo! hasn’t said no, they just want more money. In my mind the simple fact that
Microsoft has not backed down after the initial offer means ...

I have been using the latest version of Yahoo! Messenger for over two weeks now and I would like
to give a quick review of it. Overall this is not a major change from what I know as Messenger. As
it has been said before, this is evolutionary not revolutionary. From what I can see there are no
new features (at least none that I would use), the user interface (UI) is prettier, and it looks
like there have been some bug fixes; that’s it. Under the hood there are some things to note.
The current version of the YSMG protocol with version 8 is 15 and Messenger 9 has...

lately i've been reading some way of hacking yahoo messenger. youtube, hacking forums, and etc,
i've been there to ask and to learn how to hacking it. but i've been wondering every now and

is there any way to hack yahoo messenger?...

I have been aware of the latest Yahoo! Jukebox and until recently Messenger exploits for about a
week. Starting on the 3rd of February, three critical vulnerabilities were posted for datagrid.dll
and mediagrid.dll which are part of the Yahoo! Jukebox offering
(http://www.securityfocus.com/bid/27578, http://www.securityfocus.com/bid/27579 ,
http://www.securityfocus.com/bid/27590) . The reason that I waited so long to post this is because
the details were inconsistent and it didn’t add up to me. The versions of Messenger that were
listed as vulnerable are abso...

The latest post on the official Yahoo! Messenger blog appears to be out of place to me
(http://www.ymessengerblog.com/blog/2008/01/04/recording-yahoo-messenger-calls/). It is not part of
the usual suspects of promising unneeded features or unabashed promotion of Messenger. Instead it
is a fairly useful commentary on how to record a Messenger phone session using third party
applications. The Yahoo! Messenger blog references a New York Times article
(http://www.nytimes.com/2008/01/03/technology/personaltech/03ASKK-002.html?_r=1&oref=slogin) where a
user asked if...

The latest blog post from the Yahoo! Messenger development teams is about Discovr, a proposed
new way of sharing Messenger contacts. As is stands Messenger is a closed social community. It is
very hard to discover new buddies unless you start trolling around the chat rooms or have a buddy in
real life. Discovr is a method to make Messenger more like Facebook or Myspace where everyone knows
who your friends are. Discovr came from Hack Days, a common occurrence at Yahoo! that
encourages different departments to throw out new ideas. (To think Yahoo! actuall...

There’s not much meat or new content in this post but I did find it rather humorous. Richard Sinn
is apparently the software security engineer for Yahoo! Messenger and he now has a new book out

The Yahoo! Messenger development team announced that there have been a few minor upgrades to the
web version of Yahoo! Messenger
(http://blog.messenger.yahoo.com/blog/2007/09/24/yahoo-messenger-for-the-web-new-release/). From
what I can see nothing major has been added except for SMS to mobile users and a few new languages
for India. Apparently the web version of Messenger has taken off in India as nine new languages are
added for that region. You add the support for the biggest demand....

Over the past few days (It is September 23, 2007 now) I have noticed what appears to be a bug in
Yahoo! Messenger concerning unread mail. No matter if there are unread messages or not,
Messenger always reports new mail. I have even gone through the trouble of deleting EVERYTHING from
my mail account and it still pops up. The same behavior happens on Yahelite and Pidgen so it is a
server side bug. Yahoo! has been upgrading their server so I would expect that this is a side
effect of some of the upgrades. Of course this could be confined to me so let me know i...

Yahoo! Messenger is once again in the news for all the wrong reasons. This time it is a heap
overflow in the webcam component. The news was apparently first exposed my McAfee in a blog post at

http://www.avertlabs.com/research/blog/ind...er-webcam-0day/ goes into more detail explaining that
you shouldn’t accept unknown webcam invites and to possibly firewall port 5100. Security Focus has
also issued an alert at http://www.securityfocus.com/bid/25330/info but they only classify is...

Today Yahoo! announced a whole new way to communicate using Messenger. It’s the “all-new
Web-based Yahoo! Instant Messenger.” Ohh wait a minute, wasn’t there already a web version of
Yahoo! Messenger? Despite the fact that the official press release
(http://yodel.yahoo.com/2007/05/02/yahoo-messenger-hold-the-download) makes this out to be something
completely new, a web version of Messenger has been around for years. I of course will be the first
to admit that the old version was so bad that I would like to forget about it too. With the bad
taste of my p...

I read this morning at theunofficialyahooweblog
(http://yahoo.weblogsinc.com/2006/06/19/yahoo-opens-up-messenger-to-3rd-party-plug-ins/) that
Yahoo! has just released a SDK for a plugin engine that will reside in the next version of
Messenger. I can’t wait to dig into this seemingly juicy morsel of Yahoo! fun. I’m not sure
what all one can do with the SDK yet but I will be sure to report what I find. The SDK can be found
at http://developer.yahoo.com/ . A list of already published plugins can be found at

I have been having problems with my stealth setting for about a week now. Apparently when I have
all users set to invisible it works fine. Also when I go available everything appears to work fine.
The problems is when I set a custom message all of a sudden the users that I have individually set
to offline can see me. I have not been able to reproduce the results myself but it is starting to
become a problem as people that I would rather not talk to IM me now. Anyone else run into this?
Is this another bug?...

Yahoo! Protocol: Part 7 - Yahoo! Packet Structure All Yahoo! communications use TCP
over IP communication and the Yahoo! data resides in the data field of the TCP packet as shown
in Figure 13. Figure 13 - Yahoo! Messenger Packet Yahoo! extends the common TCP/IP
convention of using headers by creating its own application level header format. A Yahoo!
header is 20 bytes long and is identified by the first 4 bytes being “YMSG.” The Yahoo! header
also includes the YMSG version, message length, service type, status, and session ID. F...

Yahoo! Protocol: Part 6 - Money and Closed Protocols Even with all the bells and whistles of
Yahoo! Messenger, Messenger still follows the same basic communications architecture as most
other instant messengers. Yahoo! is based on a central server structure. First a client,
Yahoo! Messenger logs onto a Yahoo! server using a username and password. The server
authenticates the request and either allows or denies access to services. From this point most
messages sent to other users are buffered through the server. After a successful login the clie...

Yahoo! Protocol: Part 5 - Disclaimer and Legal Upon becoming a member of the Yahoo!

by Yahoo! and update any information if it changes. Section 3a, b states the following:

As with any basic instant messaging service, Yahoo! Messenger offers several basic functions.
In general, an instant messenger offers conversations between two users in real time. As a rule,
both users will see the conversation line by line as it is typed. Although not required, instant
messengers usually offer the ability to show away messages, reside in the system tray until needed,
and offer a user buddy list . In addition to these basic services, the latest version of
Yahoo! Messenger also offers more advanced features. Although not unique, these servic...

Yahoo! started its life as “Jerry and David’s Guide to the World Wide Web” in January of 1994.
Its creators David Filo and Jerry Yang, started Yahoo! as a way to track their personal
interests. As word spread of this new effective search engine, resources were soon strained.
Moving from Stanford University to Netscape facilities, and finally to its own headquarters,
Yahoo! has become one of the largest Internet names in history. At the end of the day Yahoo!
is still a business and like all businesses, Yahoo! has to make a profit and adhere to a bus...

One of the security passions that I have maintained over the past few years is the one with
Yahoo! Messenger. In recent months Yahoo! Messenger has seen a decline in users due to some
new policies. Although not as strong as perhaps a year ago, it is still very important to keep a
watch on Yahoo! Messenger from a security point of view. Messenger, just like may of the
programs we use, open a door out to the Internet. With each new door comes a unique set of security
concerns. Perhaps the biggest reason to keep an eye on Yahoo! Messenger is because the...

Way back when I had Messenger 6.0 I came across a fairly unique add-on to Yahoo! Messenger that
added the "join user in chat" function that was taken away in the migration from 5.0 to 6.0. The
program simply consisted of a file that replaced a Yahoo! DLL and re-enabled the join user in
chat function. Once I upgraded to 7.0 the program of course did not work and I started my search for
a replacment. At long last I have found it and not only does it add the join user in chat, it also
adds view webcam and much more that has been missing since the days of 5.0. The ad...
