IDA 4.9 - LocalLock Fix V2
==========================

This patch requires UNPACKED ida*.exe and ida*.wll.
Use CASPR or syd's ASPR-Stripper 2.07 to do the job !
->[http://doom.scene-gods.de/unpacker.htm]                                                                                           http://antiwpa.ru.org

I advice to use CASPR - if you use ASPR-Stripper press
ctrl+end to scroll down to the notes on the end of this doc.

About the patch:
ZWT released a version that was lock to russian only.
(you needed to set your timeszone to GMT+3 (Russian)
DVT released an fix. But it was improper it only patched
away MessageBox+Quit, but later many functions & modules don't load.
This patch will set the 'correct' value for the timezone right after the API - instead of trying to patch every jz.

In case you get "The processor module is prohibited by the key" use the included ida.key file
It unlocks Module 1..50 (50..64 is zero and probably for future use) what is seem to be
enough since there are only 33 loaderModuls in current version.

The Patch removes the blacklist so you can you use your old IDA.Key
(Background for this was that IDA.Key is stored inside the database.
So when you opened an older database containing blacklisted keydata
you get "Database corrupted" and it won't open)

As bonus patch the stupid about box at startup is removed so
IDA will start 3 seconds faster.
If you don't like the bonus remove(rename) idau64.exe, apply and
click on 'no' to stop the patch sequence.

Additional bonuspatches are the "Sorry, this database format is unsupported" fix
You normally get this message if you open an IDA 4.5 database and newer ones.
(IDA 4.3 and older works)

A more comprehensive "Database corrupted" patch than only blacklisted patch.
Now keydata can be missing or be 'corrupted' it doesn't matter anymore.
(+Patch Database is not save on close if key is invalid)

Since this is a search'n'replace patch it might also work
for future versions of IDA!
However in the first place it was made & test with version 4.9

Here's a docu about UDP 23945 to clean up IDA undercover myths

This refers to post
http://www.datarescue.com/ubb/ultimatebb.php?/topic/1/490.html


Since some ppl were complaining about that this feature is not well documented here we go:
It's all depending on the data inside ida.key (-> Details added blow)
Idag.exe scan inside the registered-to text for the string "user" and gets the number above it.
If "user" is not found at all or found at position 0..3 or the number is above 1 the networkcheck is not started.
Note: Changing the "user" inside ida.key is a good idea but changing it inside idag.exe (-> CASPR 1.100 will do a good job in unpacking) will of course do the trick.  :D
But back to the docu...
The check is performed within an extra thread (CreateThreadA!) whichs runs all the time beside the mainthread.
From the entired registered-to text a 128 bit MD5-CheckSum is created and submitted together with some other ID values like CurrentProcessId
as a 40-byte UDP broadcast packet on port 23945. (See below for details).
But before submit it tries to adds itself to the windows Firewall to avoid to get blocked
by calling win_fw.windows_firewall_enable_app dll inside IDA Dir.
	win_fw.dll!#1 (0,"The Interactive Disassembler","C:\IDA\idag.exe")
	Note: the 0 stands for Enable and 1 for Block traffic
	->Btw nice small dll that can be easy be reused in other pojects ;)
Some quick look into it reveals that it uses the COM-Interface of [Windows]\SYSTEM32\HNETCFG.DLL
just as windows to open ports...
	CreateObject("HNetCfg.FwMgr")
	hnetcfg.FwMgr::get_LocalPolicy
	hnetcfg.FwPolicy::get_CurrentProfile
	hnetcfg.FwProfile::get_FirewallEnabled
	hnetcfg.FwAuthApps::Item ... 

But again back to the UDP broadcast request. That is how it is performed in real.
So that should be also some good skeleton in case you want to implement some
simular check in you app.

Socket= WSOCK32.socket(
	Family = AF_INET,
	Type = SOCK_DGRAM,
	Protocol = IPPROTO_IP)

WSOCK32.bind(Socket,
	pSockAddr=23945,
	AddrLen = 0x10 )

WSOCK32.setsockopt(Socket,
	Level = SOL_SOCKET,
	Option = SO_BROADCAST,
	Data,	DataSize = 4)

WSOCK32.send(Socket,
	 Data, DataSize = 0x28 (40 Bytes),
	 Flags = 0 )
(Note: WSOCK32 is just a wrapper dll nearly all calls are redirect directly to WS2_32)

After that IDA switches into receivemode and listen for any incoming UDP-data on port 23945 which is
 40 byte long and starts with "IDA" and is not the paket it has sent (CurrentProcessId).
 which don't match with it's own. (Have a look 'Format of IDA Data Package' below now)

WSOCK32.recvfrom(Socket,
	 Data, DataSize = 0x28 (40 Bytes),
	 Flags = 0 )

If it receive a packet whose type is 0 (=Reply) it will compare the MD5-CheckSum with its own one and
if it matches will display a Message that someone else is also running IDA on the Network and quit.
Else (received a packet is a Request (type=1)) it will send it's will set Type=0(Reply) and the own packet again
after that it will enter the receiveloop again.


Format of IDA Data Package:

Offset  ExampleData  description
$+0	  00414449		Const Signature "IDA."
$+4     00000001		Type (0=Reply, 1=Request)

:SessionID
$+8     FDE74450		Result of Kernel32!GetCurrentProcess
$+C     010C481B		Result of Kernel32!GetCurrentProcessId
$+10    FF79D115		Result of Kernel32!GetCurrentThread
$+14    00433A7D		Result of Kernel32!GetCurrentThreadId xor 'more'
Note: 'more' = (((((GetTickCount XOR GetCurrentProcess) <<1) XOR GetCurrentProcessId) <<1) XOR GetCurrentThread) <<1)

:Serial
$+18    FFFFFFFF  	128-bit MD5-Checksum(=0x10 Byte value)
		  FFFFFFFF			of registered-to text
		  FFFFFFFF
		  FFFFFFFF
$+28

Ok thatz it so far!

{Note: encrypted data slightly modified}

As you see it consists of three parts
	Unencrypted Header
	Part1 	Encrypted SerialData
	Part2 	Encrypted SerialData Backup

Unencypted Part1 and Part2 are nearly identical expect that in part 2
'Bitarray for licensed Processore modules' must be fill with 00
The file is accessed from the End of File. One Part is 0xA0 Byte big
with is 0x7f userdata and a gap of 0x21 Bytes.
So for ex part 2 of ida.Key  would be:
part2 =(filelength - (7f+21))

Discussion:
Timestamp:	Is a 32Bit Timestamp in Unix C-Time (Seconds since 1.1.1970)
				not used in the program so far - maybe good for future timelimited keys
				Note: The timestamp is simular to the filecreation time

Bitarray for licensed Processor modules:
				Well this 64-bits Array has room for 64 processor moduls
				so if the bit is set(1) the use is allowed if clear it is not.
				implentation details ins ida.wll above reference to String
				"The processor module is prohibited by the key"

Marker		The lowbyte of the Dword should be 3D to dectect if decryption succeed
				The rest of 3 bytes is not used and the meaning is unclear

Regname		The name that apprears in the about box
				It is checked if Regname in the header in Part1 and Part2 matches
				until ida.wll!#xx returns it to idag.exe

So far to the documentation.
If you've enough time IDA is not only good to find out how other programs work (or why they don't) ,
it's also good for to explorer it itself.
It's the best and only all in one solution for all kinds of executable code.
PE32, and PE64 For AMD54 or IA64 Windows, Java, CLR(.NET), old 16-Bit Windows 3.11 NE-Exe, Handy & Playstationroms and even with that Z80 Rom for my TI83 Calculator.
On unknow Assemblers the auto comments you can enable in options helps a lot.



BTW what happend to the Freewareversion of IDA, which was discontinued and disappeared years ago.
The installationpacked was really small and it were very good
So for remote on-the-fly of analyse of computer problems I use Ollydebug

(DaylightBias==0) or (DaylightDate.month==0) -> flag1=0
DaylightBias :
Bias value to be used during local time translations that occur during daylight saving time.
This member is ignored if a value for the DaylightDate member is not supplied.
This value is added to the value of the Bias member to form the bias used during daylight saving time.
In most time zones, the value of this member is -60.


GMT=(Bias+StandardBias)*60

Bias:
Current bias for local time translation on this computer, in minutes.
The bias is the difference, in minutes, between Coordinated Universal Time (UTC)
and local time. All translations between UTC and local time are based on
the following formula: 	UTC = local time + bias

StandardBias
Bias value to be used during local time translations that occur during
standard time. This member is ignored if a value for the StandardDate
member is not supplied. This value is added to the value of the Bias
member to form the bias used during standard time. In most time zones,
the value of this member is zero.
