TDL Rootkit Detector Vista download - Detects the presence of TDL
We recently published an analysis of the TDSS rootkit, and just as we expected, TDSS continues to evolve. A new variant of the rootkit, TDL-4, which can infect both 32-bit and 64-bit operating systems, appeared sometime between July and August, 2010. In this article, we describe a new loading method used by the rootkit and examine how the rootkit bypasses PatchGuard and the Windows code integrity mechanism, the protection system built into 64-bit Windows operating systems.ComponentsImportantly, TDL-4 has a different set of components to TDL-3. Here is a list of the components included in TDL-4:bckfg.tmpcfg.inicmd.dllcmd64.dlldrv32drv64ldr16ldr32ldr64mbrLike the previous variant, the rootkit uses its own file system that is encrypted using the RC4 algorithm. It stores all of its files in the last sectors of the physical drive. Structures of the rootkit’s file system after decryption As with previous versions, the rootkit makes use of a configuration file. Sample data in a TDL-4 configuration fileThe TDL-4 configuration file is slightly different from that of TDL-3, the main difference being the rootkit version number (version=0.02). It can be seen from the list of components above that file names include the numbers 32 and 64. This demonstrates that the rootkit should work both on 32-bit and 64-bit operating systems. Infection and loadingMBRThis time, a different and already proven method of infection has been chosen for TDSS. Like another notorious rootkit, the bootkit, TDL-4 infects the Master Boot Record (MBR). This enables it to load before the operating system, right at the beginning of the computer’s boot-up sequence.The code in the MBR uses an unsophisticated encryption algorithm, but even small modifications to the algorithm are sufficient to evade signature-based detection by most antivirus products. Infected and encrypted MBR code Decrypted MBR code with the ldr16 string shownThe main function of the MBR loader, which is small in size, is to search the rootkit’s encrypted partition for the ldr16 component, load it into RAM and pass control to it. Searching for ldr16, loading it into RAM and passing control to it LDR16Once loaded, ldr16 hooks BIOS interrupt 13h, which is used for disk input/output.

Just download the program, click "Start Scan", and it should take care of everything else.What you will notice, if you're not infected by anything, is that scan times can be extremely fast - perhaps just a second or two. And that's because Rootkit Remover works with known threats only, so there's no need to examine every file on your system - it already knows exactly where to look.Of course this also means that Rootkit Remover is no substitute for a full antivirus engine, something which might be able to prevent your system from being infected in the first place. But if you think you may have a rootkit and your current security package can't help, then it may be a good idea to give Bitdefender Rootkit Remover a try. Verdict: It has its limitations, but if you think your system is infected by malware and your current antivirus tool can't help then Bitdefender Rootkit Remover may be worth a tryComments
