The other accesses I've seen were from Brazil and America amongst
others, so I think all you can say confidently is bots exist in
Banglasdesh as well. I doubt they are using bots for some, and their own
IPs for others, the bad guys are more organized than that.

My guess is it is automated exploit using stolen or guessed credentials.
Looking at the Yahoo cookie handling, it doesn't look too sophisticated,
so if you browse another website with the cookie still in your cookie
jar and Yahoo have another XSS vulnerability somewhere in their domain
(likely)...

I kill cookies on exiting the browser - bit of a pain - and sometimes my
browser sessions last weeks at a time so probably doesn't buy me much.
