ular analysis of the Process List can be useful For example, you could schedule regular AT jobs to look for remoteexe or ncexe in the Process List and kill them There should be

Beginning with Windows XP, Microsoft provided the netstat o switch that associates a listening port with its owning process

Attackers now have a perpetual back door into this system until the administrator gets wise and manually removes the Registry value Don t forget to check the %systemroot%\profiles\%username%\Start Menu\ programs\startup\ directories files here are also automatically launched at every boot!

Windows provides many security tools and features that can be used to deflect the attacks we ve discussed in this chapter These utilities are excellent for hardening a system or just for general configuration management to keep entire environments tuned to avoid holes Most of the items discussed in this section are available with Windows 2000 and above See Hacking Exposed Windows, Third Edition (McGraw-Hill Professional, 2007; http://www winhackingexposedcom) for deeper coverage of many of these tools and features

no reason for a self-respecting NT administrator to be running remote, since it doesn t perform any internal authentication The NTRK killexe utility can be used to kill any rogue remote servers periodically The following example illustrates the AT command used to launch a remote-killer every day at 6 AM This is a bit crude, but effective; adjust the interval to your tastes

the system name located to the right In addition, each host has an HINFO record that identifies the platform or type of operating system running (see RFC 952) HINFO records are not needed, but they provide a wealth of information to attackers Because we saved the results of the zone transfer to an output file, we can easily manipulate the results with UNIX programs such as grep, sed, awk, or perl Suppose we are experts in SunOS/Solaris We could programmatically find out the IP addresses that have an HINFO record associated with Sparc, SunOS, or Solaris:

C:\> at 6A /e:1 ""kill remoteexe" Added a new job with job ID = 12 C:\> at Status ID Day Time Command Line ----------------------------------------------------------------------12 Each 1 6:00 AM kill remoteexe C:\> kill remoteexe process #236 [remoteexe] killed

tablished sessions Periodically checking netstat for such rogue connections is sometimes the best way to find them In the next example, we run netstat an on our target server while an attacker is connected via remote and nc to 8080 (type netstat / at a command line for understanding of the an switches) Note that the established remote connection operates over TCP 139, and that netcat is listening and has one established connection on TCP 8080 (additional output from netstat has been removed for clarity)

We can see that we have 388 potential records that reference the word Solaris Obviously, we have plenty of targets Suppose we wanted to find test systems, which happen to be a favorite choice for attackers Why Simple: they normally don t have many security features enabled, often have easily guessed passwords, and administrators tend not to notice or care who logs in to them They re a perfect home for any interloper Thus, we can search for test systems as follows:
