Quoting n3td3v,
Because we all know Yahoo! has no account security, so kids aged 15
can hack an account. Yahoo! is like hacking for beginners. Its easy to
do, and therefore a great network to learn skills.. bravo Yahoo!, you
have a use after all.
Hm, hm. Yahoo's rudimentary security 'features' such as account
lockout policy (12 hours after several failed login attempts) is most
often used as a DoS against that account owner.
Plus numerous "booters" exploiting holes (read: buffer overflows) in
ypager.exe, and you have a perfect way to kick someone out from chat
and not let him/her/it return.
They (at Yahoo) try to make it harder to write your own chat
client/bot/messanger by slightly changing their CRAM (and still, it
was reversed, nevermind that it nowadays consist of several MD5-like
routines and is heavily obfuscated against casual reverse-engineers
:P)

Couldn't hold myself, this is FD after all :)

Thats the least of it. Yahoo! Messenger has no privacy. You can detect
people who are invisible easily. A friend has developed a good open
source project at buddy-spy.com You might want to check that out.
Yahoo! Messenger team are scrambling to build a brand new robust and
secure protocol for 2005, to particularly stop kids and vulnerable
females from getting unwanted attention through the fundamental
privacy flaws in the protocol my friend has been able to use to
develop buddy-spy.

If you're worried about your kids saftey on Yahoo! messenger, don't
use it. At least until privacy flaws have been fixed.

I could continue the list of Yahoo! glitches and flaws, but i'll leave
it at the lack of privacy on Yahoo! Messenger for now.

n3td3v, the greatest!
Yahoo sec admins are no use.
