A fake MSN's address

Hi all,
today, while I'm chatting through MSN with my friends, I received a invite to add in my contact list one contact. The contact is: rosaliareeves38@hotmail.com

Being curious, I accepted the invitation to try to understand if it were a real contact or a classic fake account.

So I'm starting a conversation with it saying: " Hi ", and I received a very very fast reply which said: " I know a way we can chat and have a better time.. do you cam? ". Is simple to understand that the answer to the question is the second ;).

I also noticed that as a personal message has a web address; http://shortlinks.co.uk/wuz

Going to this address we are redirected to another; http://www.mywebcamcrush.com/JessiesHotCam10

We can see that the site is about web chat which it calls to register to see through cam one girl named Jessica. There is also a false interactive chat with girl to the right.
Well, there is not to say anything but only stay away from this contact and this site which is obviously a classic scam site. =)

Bye, see you in the next post.

A way to work with SoftIce on XP SP3 through VMware

Hi to all,
after a couple of month I return to write on my blog...

This time I want to provide you a very usefull pack with everything needed to work with SoftIce on XP SP3 through VMware.

Follow these steps:

1. Copy compuware.dat to your C:\windows\system32\drivers folder;

2. Start Autorun.exe and while you are installing, You use the serial: 7888-5842DD-DD ( you can also use the keygen provided with this pack ) ;

3. When you must choose for option 14-day trial or select the file license, choose the file license, don't choose 14-daytrial!
Make the path to : C:\windows\system32\drivers\compuware.dat
Finish the installation;

4. Restart;

5. Copy OSINFO.DAT to your C:\windows\system32\drivers folder and overwrite if it exists;

6. Disable DEP by modifying c:\boot.ini

/noexecute=alwaysoff


7. Modify *.vmx:

svga.maxFullscreenRefreshTick = 5
vmmouse.present = "FALSE"

8. Copy dbghelp.dll and symsrv.dll to C:\Programmi\Compuware\DriverStudio [or DriverSuite]\Softice\SymbolRetriever directory and overwrite if them exist;

Now run SIce and it'll work [ hopefully ;) ] fine on NT and XP on VMware.

Here the link to download the Pack: SIce Pack

Thx to all ExeTool's Member but a special thx for WhoCares!!!

Patch Diff 2: A useful plugin for IDA Pro

PatchDiff2 is a plugin for the Windows version of the IDA dissassembler that can analyze two IDB files and find the differences between both. PatchDiff2 is free and fully integrates with the latest version of IDA (5.2).
The plugin can perform the following tasks:

• Display the list of identical functions;


• Display the list of matched functions;


• Display the list of unmatched functions (with the CRC);


• Display a flow graph for identical and matched functions.

The main purpose of this plugin is to be fast and give accurate results when working on a security patch or a hotfix. Therefore this tool is not made to find similar functions between two different programs.
Patchdiff2 supports all processors that IDA can handle and is available in two versions: 32 bit and a 64 bit.
