User2sid and Sid2user are two small utilities for Windows NT, created by Evgenii Rudny, that allow the administrator to query the SAM to find out a SID value for a given account name and vice versa. User2sid.exe can retrieve a SID from the SAM (Security Accounts Manager) from the local or a remote machine and Sid2user.exe can then be used to retrieve the names of all the user accounts and more. These utilities do not exploit a bug but call the functions; LookupAccountName and LookupAccountSid respectively. These tools can be called against a remote machine without providing logon credentials except those needed for a null session connection. These tools rely on the ability to create a null session in order to work.

Creating your own driver loader in C | Driver Loader | Source Code | Rootkit

Technically, there’s 2 way of loading a rootkit according to Greg Hoglund when he wrote Rootkits: Subverting the Windows Kernel book.  One is called The Quick-And-Dirty Way to Load a Driver.  This method allows you to “load a driver into the kernel without having to create any registry keys.  “Pageable” refers to memory that can be swapped to disk. If a driver is pageable, any part of the driver could be paged out (that is, swapped from memory to disk). Sometimes when memory is paged out, it cannot be accessed; an attempt to do so will result in the infamous Blue Screen of Death (a system crash)” by using an undocumented API call.  Read the rest of this entry »
