Idiots Proof End
Hi,
Today moring I’ve received a link from an MSN Contact of mine, she was offline.
Code:
hxxp://checkdiz.info
at first analysis with Malzilla it reveals three other links
Code:
hxxp://checkdiz.info/indexx.php
hxxp://www.cpashield.com/abuse.html
hxxp://checkdiz.info/counter.php
indexx.php has a level of indirection to
Code:
hxxp://fileho5t.info/indexxx.php
counter.php leads to
Code:
hxxp://www.ipcounter.de/stats.php?u=50076309
and finally the most intersting cpashield.com/abuse.html contains obfuscated javascript code
Code:

Pay attention, this kind of accessing system could lead to severe Privacy Compromisal, it acts as Spam and could work as Data Miner.
See you to the next post..

How do i remove this?
May 25, 2008 at 12:48 pm |
Change MSN Password
May 25, 2008 at 12:52 pm |
hm… what does it actually try to do?
May 25, 2008 at 1:07 pm |
I’ve not inspected deeply, but two hardened javascripts are not a good sign, I suspect that’s a Spam/DataMiner, but could have also other functionalities.

Once msn password has been changed is there anything else that needs to be removed from the computer?

I think the page was encrypted using CryptHtml XP. The first script decoded by evilcry is only used to disable some page features (i.e. mouse gestures).
Second decoded script is:

Nice post btw, it’s a nice finding evil

Thank you for the Investigation Zai!, great to know what is doing the second JS
@Soho: Yes, you only need to change Pwd
