3 ITA
Per chiunque fosse in possesso di un Nokia E63, e avesse sottoscritto un piano tariffario 3 con l'opzione X-series, non è possibile usufruire di skype, in quanto il client non risulta disponibile tra le applicazioni compatibili. Poco male. Il file skype.sis è un'applicazione per Symbian S60 disponibile sul sito 3 X-series se si usa un E71, o uno di quei device compatibili per 3. Scaricatelo ed installatelo sul vostro E63. Funziona benissimo, il traffico generato viene decurtato dalle soglie Xseries di 3 senza alcun problema. Per la ricezione delle chiamate usando Skype di 3 è necessario avere un piano flat, mentre per le chiamate in uscita si passa da un centralino SIP.

3 UK
Anyone have a Nokia E63 and use the mobile operator 3 (It, Uk, Ireland?) can use the option x-series (free web using wwww3, skype and msn). The device Nokia E63 for 3 is not compatible with Skype .. this is not true. You can get the file skype.sis to use with your Nokia E63 and your x-series option on 3 (it work only if you have subscribed the x-series pack).

I'm reversing win32dd, the tool of Matthieu Suiche, used to dump the entire content of RAM.

The software, in the latest release, can use:

• \\Device\PhysicalMemory
  
• MmMapIoSpace
  
• PFN database
  

The article of Anton Bassov describe step by step what do to use \\Device\PhysicalMemory ..

I have a new netbook ... an Aspire One 751h

Processor1.33GHz Intel Atom Z520
Memory 1GB, 533MHz DDR2
Hard drive160GB 5,400rpm
ChipsetIntel SCH US15W
GraphicsMobile Intel GMA 500 (integrated)
Operating SystemWindows XP
Dimensions (WD)11.8 x 8.5 inches (8.8 inches with battery)
Height1.0 inches
Screen size (diagonal)11.6 inches
System weight / Weight with AC adapter3.0/3.6 pounds

Today I tried Visual Studio 2008 on Aspire and it's work without problem.. but the project is small actually .. but I'm hope to expand it on weekend..

Tomorrow I will install DDK, Debuggers and other utilities for a mad guy

The only problem is linux.. I tried Ubuntu Netbook Remix 9.10 .. but the chipset is not supported.. without support X don't work properly ... the supported resolution of monitor is 1366x768, without driver ubuntu use only a 1024x768 pixel .. and it's too bad

I need the support for chipset!!

So, I will be brief..

do You think to use a dongle to protect your software from piracy? Ok.. it be a beginning but..

Please don't write code like this

bool check_dongle()
{
   SKEY_LINK struc1;
   CHAR login_passphrase[] = { /* array of value */ };
   CHAR response_passprase[] = { /* array of value */ };

   struc1.command = 'A';

   int x = rand() % 0x14;

   memcpy(&struc1.data1, &login_passphrase[x*8], 8);

   if (smartlink(&struc1) == 0)
      return false;

   if (memcpy(&struc1.data1, &response_passphrase[x*8], 8) != 0)
      return false;

   return true;
}

I know it's possible to bypass this dongle check putting nop after two if to bypass check..
but, whereas login_passphrase and response_passphrase are respectively the input buffer before ?AES? encryption and response buffer after ?AES? encryption.. and they are into program binary .. why choose this dongle??

I suppose that the encryption function is AES, it's supported by dongle.. and actually this allow me to write an emulator, replacing smartkey dll with custom dll

Skype have .text section encrypted ...

Run skype .. stop the main thread using a debugger or process explorer..
attach it with a debugger and dump to file the .text section (from offset .00401000 to end of section)..

Perform a full copy of skype.exe, open the copy with an hex editor, and replace the text data on file with the dump (don't replace all bytes with dump.. only .text physical size).

Now, you can open your copy with ida and using a Delphi plugin you can rebuild all classes, all vcl events, enumeration, strings, float data without problem..

now, if I have time today, I begin the coding of plugin to improve the performance of my script .. because I have a bit of problem with inner classes ..

it's time to go in office
