Backtrack Hackers OS

BackTrack
 is
 the
 world’s
 leading
 penetration
 testing
 and
 information
 security

auditing
distribution.

With
hundreds
of
tools
preinstalled
and
configured
to
run
out

of
 the
box,
BackTrack
4
provides
a
solid
Penetration
 testing
platform
 
 ‐
 from
Web

application
Hacking
to
RFID
auditing
–
its
all
working
in
once
place.

Behind
the
curtains





BackTrack
Base



There
 have
 been
many
 changes
 introduced
 into
 BackTrack
 4
 ‐
most
 notably,
 our

move
to
an
Ubuntu
 Intrepid
base.
We
now
maintain
our
own
 full
repositories
with

modified
Ubuntu
packages
in
addition
to
our
own
penetration
testing
tools.


Another
significant
change
is
the
updated
kernel
version,
currently
at
2.6.29.4.
This

new
kernel
brought
 an
onset
of
 internal
 changes,
which
have
 greatly
 changed
 the

structure
of
BackTrack.


BackTrack
Kernel


We
no
 longer
use
 lzma
enabled
squashfs
as
our
 live
 filesystem,
which
on
one
hand

results
 in
 larger
 ISO
 size,
but
on
 the
other
hand,
 frees
us
 from
having
 to
maintain

our
own
kernel
patches.
This
 is
especially
painful
 these
days,
as
squashfs
 is
slowly

moving
into
the
mainstream
kernel
(at
the
time
of
this
writing).

BackTrack
 4
 uses
 squashfs‐tools
 version
 4.0
 (which
 is
 not
 backward
 compatible

with
previous
versions),
and
the
inbuilt
squashfs
kernel
module,
which
is
present
in

2.6.29.4.
AUFS
is
used
as
the
unification
filesystem
(aufs2.x).

Several
 wireless
 driver
 injection/optimization
 patches
 have
 been
 applied
 to
 the

kernel,
 as
 well
 as
 a
 bootsplash
 patch.
 These
 patches
 can
 be
 found
 in
 the
 kernel

sources
package
(/usr/src/linux/patches).



Packages
and
Repositories



One
of
 the
most
significant
changes
 introduced
 in
BackTrack
4
are
 the
Debian
 like

repositories
 available,
which
 are
 frequently
 updated
with
 security
 fixes
 and
 new

tools.
This
means
that
if
you
choose
to
install
BackTrack
to
disk,
you
will
be
able
to

get
package
maintenance
and
updates
by
using
apt­get
commands.

Our
 BackTrack
 tools
 are
 arranged
 by
 parent
 categories.
 These
 are
 the
 categories

that
currently
exist:

•  BackTrack
‐
Enumeration

•  BackTrack
‐
Tunneling

•  BackTrack
‐
Bruteforce

•  BackTrack
‐
Spoofing

•  BackTrack
‐
Passwords

•  BackTrack
‐
Wireless

•  BackTrack
‐
Discovery

•  BackTrack
‐
Cisco

•  BackTrack
–
Web
Applications

•  BackTrack
‐
Forensics

•  BackTrack
‐
Fuzzers

•  BackTrack
‐
Bluetooth

•  BackTrack
‐
Misc

•  BackTrack
‐
Sniffers

•  BackTrack
•  BackTrack
‐
Debuggers

•  BackTrack
‐
Penetration

•  BackTrack
‐
Database

•  BackTrack
‐
RFID

•  BackTrack
–
Python
‐
VOIP



Meta
packages


A 
nice
 feature
 that
arises
 from
 the
 tool
categorization,
 is
 that
we
can
now
support

“BackTrack
meta
 packages”.
 A
meta
 package
 is
 a
 dummy
 package
which
 includes

several
 other
 packages.
 For
 example,
 the
 meta
 package
“backtrack­web”
 would

include
all
the
Web
Application
penetration
testing
tools
BackTrack
has
to
offer.


Meta
Meta
Packages

We
have
two
“meta
meta
packages”
–
backtrack­world
and
backtrack­desktop.


backtrack­world
 contains
 all
 the
 BackTrack
 meta
 packages,
 while
 backtrack­
desktop
 contains
 backtrack­world,
 backtrack­networking
 and
 backtrack­
multimedia.
 The
 latter
 two
meta
 packages
 are
 select
 applications
 imported
 from

Ubuntu
repositories.



Up
and
running
  with
  BackTrack



We’ve
made
a
short
movie
called
“up
and
running
with
BackTrack”
–
showing
some

common
 and
not
 so
 common
 features.
A
good
place
 to
 start
 in
order
 to
grasp
 the

new
changes
in
BackTrack
4.


Installing
BackTrack
to
Disk


BackTrack
 4
 (both
 barebones
 and
 full
 version)
 now
 contains
 a
modified
Ubiquity

installer.

The
install
should
be
straight
and
simple.

a
video
tutorial,

backtrack‐hard‐disk.html

Updating
Backtrack

Keeping
BackTrack
up
to
date
is
relatively
simple
by
using
the
apt‐get
commands.

apt­get
update
synchronizes

your
package
list
with
our
repository.

apt­get
upgrade
downloads
and
installs
all
the
updates
available.

apt­get
dist­upgrade
downloads
and
installs
all
new
upgrades.




Installing
BackTrack
to
USB




The
 easiest
method
 of
 getting
 BackTrack4
 installed
 to
 a
 USB
 key
 is
 by
 using
 the

unetbootin
utility
(resent
in
BackTrack
in
/opt/).
