Another Chinese Internet Fraudulent (yhoo-it.com)

While I was watching 'The Pacific' movie suddenly I just get a Yahoo Messenger popup message from my old friend (which is he's already Rest-In-Peace on Aug 2009 ago). This is interesting and kind of surprise for me while seeing my very close friend suddenly 'wake-up' from his long rest. I was monitoring this scammer about few months ago after surprising his online status. Check this out from the chatting using web browser YM:

From the given shortened URL it will redirect user to the following URL:

http://yhoo-it.com/?id=4ccda25f27843014&s=1&user=matkamil2000

The URL seem to be already expired. But soon it will appeared again. The actual website will appear some kind of offering  money that needs user to input their user name and email.

Let's take a look closer on the URL. The URL seem to be trying to fool the user that pretend it was coming from Yahoo. Based on whois information the URL was registered from China. Obviously.

Since I don't trust any source from China even their web hosting provider, I make some Nmap scanning to seem what its got. The web server seem to be running on Unix machine with several web services port opened.

The Yahoo Messenger online status is coming from the expired phone number which probably has been taken by China scammer that live in Malaysia. Malaysia has multicultural country and it's not impossible that a Chinese from China can disguise as Chinese from Malaysia. Another thing is that probably the YM account has been stolen from his machine via malware infection.

More updates coming up soon.
