Rootkit TDL-4 (TDSS, Alureon.DX, Olmarik, TDL) 32-bit and 64-bit Sample + Analysis links -
Update July 7
Old version 3 -  See August 27, 2010  TDL3 dropper (x86 compatible with x64 systems).
General File Information - April 2011
 This is an updated version of TDL4, which made a lot of news recently thanks to being named the ‘indestructible’
botnet. This is the last / current version and it is dated April 2011 (the previous version is from January 2011)
All the credits and many thanks for the files and comments go to @EP_X0FF @InsaneKaos @markusg
@USForce from KernelMode.info. I am posting the files and their comments here because of the the large
number of inquiries for the updated version.
1) Bypassed Microsoft patch (STATUS_INVALID_IMAGE_HASH error overwritten) to be able again
to infect x64 OS
2) Bypasssed Microsoft patch to kdcom.dll (this version of TDL4 checks kdcom resource directory size
on the x64 version of it, whether it is == 0x110 || 0xFA)
2) Improved disk minport filtering hook
Version history:
1. 0.01 firstly detected ITW in the end of July 2010
2. 0.02 August 2010, version with x64 support
3. 0.03 September 2010, small changes, new C&C library
4. In April 2011 Microsoft released KB2506014 targeting 0.03 version, exactly boot loader and kd
dll - and it was able to successfully prevent TDL4 from working. However, the rootkit support
strike back within two weeks releasing their update, which could bypass the MS patch. The
rootkit version wasn't changed.

TDL4 common information
First kernel mode rootkit compatible with x64 Windows.
Uses bootkit technique to load itself and bypass drivers signing restriction on x64
Uses payload C&C dll injection (cmd.dll for x86 and cmd64.dll for x64).
To keep it's data uses own VFS where stored following files:
cfg.ini (configuration text file, replaced previously used config.ini)
cmd.dll (payload dll to be injected into x86 processes)
cmd64.dll (the same but for x64)
mbr (copy of original main boot record)
ldr16 (rootkit loader parts, gets control from infected mbr and provides further rootkit
loading)
ldr32 (rootkit driver, representing fake KD dll, responsible for loading main rootkit
driver)
ldr64 (ldr32 version for x64 systems)
drv32 (main rootkit driver, VFS support, modifications hiding)
drv64 (drv32 version for x64 systems)
may store additional files or payload downloaded by cmd library.
Rootkit renders Windows XP (x86/x64), Windows 2003(x86/x64) into unbootable state after
infection (infection method restriction).
Current versions
rootkit 0.03
C&C library version 0.163 (cmd.dll)
