Possible Rootkit Issue (TDSS)+


It must be noticed that these were developed before the in-kernel symbol resolution technique to be presented later, so they might appear a bit unsophisticated. The rootkit also employs a trick using the system registry key ServiceGroupOrder.

It looks complicated but it is not and just a matter of looking up the necessary information in kernel structures. The bootkit implemented similar technologies: in our analysis of the bootkit, we noted that such malicious programs were very likely to gain popularity among cybercriminals as they are simple to use The other one, uio_createwithbuffer is private extern and used by uio_create. The instruction is: If the number of AffId records containing partners' IDs is larger than 169, then return 1, otherwise execute calculation of the MD5 hash-function for 20 million times Quite

Whitman, Herbert J. There is a wide variety of affiliate marketing programs; in this specific case we are talking about the affiliate programs promoting malicious programs and/or rogue antivirus solutions. The kernel loads dyld and jumps to __dyld_start // which sets up some registers and call this function. // // Returns address of main() in target program which __dyld_start jumps to This causes errors in various anti-rootkit tools which need to open this volume to conduct a low-level analysis of file system structures.

Its prototype is: proc_t proc_find(int pid) Kernel is just another task with PID 0, so just execute proc_find(0) and get the required structure pointer. Kernel memory is at a premium :-) --[ 4 - Executing userland binaries from the kernel This section describes a technique to execute userland processes from a kernel extension (not tested have a peek at these guys The instructions that need to be matched are ADD and CMP (this assumption appears to hold always true).

Up to Snow Leopard, Apple removed the symbol table from the kernel space so there was no easy way to solve non-exported symbols inside the kernel extension or I/O Kit driver. Still, such signs have a little chance of being caused by an infection. This function is only used at exec_mach_imgact(). It must be modified to support specific versions and releases.

The most interesting VFS related structures to our purposes are: - struct filedesc: defined at bsd/sys/filedesc.h, represents the open files in a process. - struct fileproc: defined at bsd/sys/file_internal.h, represents each For example, the partner with ID# 20106 infects computers using fake codecs that are allegedly needed to watch a video clip on a specific web site. After we have found the free space and the full Mach-O header is in our buffer, we just need to add a new LC_LOAD_DYLIB command. If anything changes it will break compatibility and potentially crash or expose the rootkit.

You can find the info how to download a file on the following pages: For users of Windows 8 For users of Windows 7 For users of Windows Vista Run the TDSSKiller.exe The OS.X/Crisis spyware implemented an interesting solution. The idea is that launchd will restart our target process and dyld will be responsible for executing our code. Big oaks grow from little acorns, and this was very much the case with TDSS; the rootkit technologies implemented in the first version (driver functionality) was relatively simple even back in

What usually happens is that only the filename is matched - that is the information directly available from the structures available in those three syscalls. One of the annoying obstacles that Apple introduced against development of rootkits is the lack of kernel's full __LINKEDIT segment up to Snow Leopard. For this reason, descriptions from different sources may vary in the information they offer. Having the uio buffer created the last step is to execute the read: error = VNOP_READ(kernel_vode, uio, 0, NULL); If successful, the buffer will contain the first page (4096 bytes) of
