You're right. I was not aware of it, that's good to know (an extra of 
security mesaures does not hurt anyone):

What actually happened? If it was just that people got messages 
appearing to come from you, that's not unusual - once someone knows your 
email address it is quite easy to fake an email that looks like it came 
from you. This can happen without your account having been hacked - it 
could be that a friend of yours has a virus on their computer that sent 
their address book to a spammer, or as a result of your email address 
being publicly available on the web somewhere. One question is whether 
the emails sent in your name were to people you know, or just random 
addresses?


The reason people do this is usually so that someone else gets the 
hassle/blame for their spamming / phishing activities, or in the cases 
where they have someone's address book, because someone is more likely 
to open an attachment that looks like it comes from a friend. It is most 
likely nothing to do with you personally.


If you have definite evidence that someone other than yourself can read 
your inbox, or other information that is only available by logging in to 
your account, then that's when you need to change your password etc. In 
that case, you should probably also contact Yahoo to let them know.


Hope this helps,

andy baxter.

Most services I know (I just checked on Gmail) don't allow changing the 
password unless you also provide the old password, even if you are 
already logged in.

That will only prevent from cases of cookie session stealing, which are 
not very usual on wired networks but on wireless environments running on  
untrusted networks (like coffee shops, airports...).

If the user is logged in with that option set, keeps the session opened 
and leaves the computer unattended, anyone can start using his account 
for their own purposes (sending massively e-mails, changing the 
password...). Having a completely encrypted session in the above 
situation is useless because the user is already logged. 

Common sense is often the best defense.

For Gmail, turn on the secure connection option so that the entire session is 
encrypted rather than just the authentication.

Open a new account with another company (GMail, etc...)

Maybe by using a weak password or by leaving your session opened. Try to 
harden it for the next time and do not use the "remember me" option.

I once had a password changed.  As far as I could tell, my account had not yet 
been used when I noticed and reclaimed the account.

And how is an account compromised?


Looks like it's a growing trend to me. One of my friend was hit a while 
ago as well. Because she is not that tech savvy, I couldn't figure out 
how it actually happened either. Do you have any clue yourself? 



It's a seldomly used Yahoo! account. It happened once before also with a

Looks like it's a growing trend to me. One of my friend was hit a while 
ago as well. Because she is not that tech savvy, I couldn't figure out 
how it actually happened either. Do you have any clue yourself? 

Don't worry if you don't. you are not the first victim. While I was 
trying to find the reason for her, I found the following, 

Am I sending out spam?
http://boards.straightdope.com/sdmb/showthread.php?t=633043

in which the OP says,

"1)I'm ridiculously careful about that kind of stuff and I'm not sure 
I could be tricked into it.
2)This is a seldom used account. It's not used for any social 
networking sites, I never would have typed in the username/password 
anywhere other then on the webmail page and my phone (it's a POP3 
account).. . ."

In other words, it is happening to those who are careful about such 
things. So any hints might help.

Judging from her email header, I can tell that the spammer was really 
able to get into her account, send email from within the yahoo web mail 
interface, to all her contacts, using an Android cell phone through the 
YahooMail Mobile phone Web Service. 

BTW, the spammer IP address was 117.195.97.137, and the 117.195.96.0/20 
address block (117.192.0.0 - 117.207.255.255) belongs to BSNL Internet in 
India, according to a whois lookup.

Here is the full email header:
