If we need more we'll add it here. // PCDB The caller initializes a CONNECT_IN structure and passes it to our driver as the input buffer of the IOCTL_OSRVMPORT_CONNECT IOCTL sent via a Win32 DeviceIoControl request. Along your journey to exam readiness, we will: 1. KeInitializeTimer fills the KTIMER structure, successively KeInitializeDpc creates a Custom DPC and finally KeSetTimerEx sets the absolute or relative interval at which a timer object is to be set to a have a peek here

The next call accomplishes the same task, this time deleting: \\registry\\MACHINE\\SYSTEM\\CurrentControlSet\\Enum\\root\\LEGACY_*driver_name* Next we see a call to an important routine: 100037A5 mov Object, eax ; Object = DriverObject 100037AA call sub_100036CA Rating: 13-May-10, Nate Bushman "Feedback" Over all the article is very informative, but I think there should be a references section added to this article 1. the modern world: net helpmsg 4006 Reply With Quote 20.05.2006,12:07 #3 Raygmar New User Join Date 19.05.2006 Posts 4 Yes, I have the image file recorded in a DVD. Let's check out the code from beginning: If you remember, the selected system driver to be infected is stored as registry entry and starts with a ‘dot'.
Let's first look at the first call of the routine, call sub_10002D9F, which takes as argument the previously described SourceString.

Like the DPC (Deferred Procedure Call), the System Thread will serve network purposes. __End Of System Thread Analysis__ Now we are on the final piece of code of DriverEntry, an IoAllocateWorkItem
The important points to notice in this function are where the driver returns MODE_DSP_WRITE_PROTECT, which tells the requestor that this media is read-only and the MODE_PAGE_CAPABILITIES handler where the driver returns ZeroAccess will survive this cleaning process and reinstall itself onto the fresh copy of Windows.

We will load a kernel-mode debugger, such as Syser.

We have shown only the SCSIOP_READ handler in Figure 11 since the write handler is almost exactly the same. Is there any way I can correct the error? But let's see in detail what this mean. Inside the call sub_1000292A we have schematically another set of IRP parsing rules, this time directly focused on three specific areas: Core ZeroAccess rootkit file queries Power IRPs Malware IRP Requests

Check This Out Another issue to be aware of is that the operations received depend on the type of device being exported, and the completion statuses that the driver returns must be a SRB_STATUS_XXXXX

Installation Well, I suppose that since we now have discussed how the driver works we had better discuss how to install it.

Its possible that its conflicting with any other back up device you may have. And it still didn't create any virtual device, neither did it give any error message. If the creation of the driver object succeeds, the initialization function is invoked with the same parameters passed to DriverEntry. In ESI, if allocation succeeds, we have the MDL pointer, used by MmMapLockedPagesSpecifyCache that maps the physical pages that are described by MDL pointer, and allows the caller to specify the
Essentially the malicious IRP handling function is going to need to parse an impressive amount of I/O request packets to verify if core rootkit files are touched.
