On this episode of SecuraBit:
Multiboot Security DVD
Mubix posted an awesome link on his blog to a Multiboot Security DVD that allows you to choose which common security distros, all on one medium!
OS Choices:
Backtrack 3
Damn Small Linux 4.2.5
GeeXBoX 1.1 (not geekbox )
Damn Vulnerable Linux (Strychnine) 1.4
Knoppix 5.1.1
MPentoo 2006.1
Ophcrack 1.2.2 (with 720 mb tables)
Puppy Linux 3.01
Byzantine OS i586-20040404
Make a bootable FAT32 USB stick using Unetbootin
Some distros the Securabit guys would like to see added:
Helix
Intelguardians Samurai
RedHat/Fedora OpenSSH Compromises
As noted on the Securabit website, a Fedora and Red Hat Enterprise Linux servers were compromised.
The ComputerWorld Blog - Linux Security Idiots article explains how the servers were compromised
-Stolen SSH keys are used to gain access to the system
-After that, rootkit "phalanx2" is installed and steals more SSH keys
-Obviously this could be used to install any malware at all
The RHEL offshoot CentOS was not affected by the compromise.
Joomla Vulnerability
US CERT Joomla! Password Reset Vulnerability
Joomla Core Exploit Announcement - Password Remind Functionality
Joomla user password reset vulnerability being actively exploited

Vulnerbilty of BGP
This exploit of Border Gateway Protocol allows the attacker to
monitor internet traffic and forward it to anywhere in the world. Five
hours of traffic was forwarded to New York during Defcon 16. This
vulnerability is going to be bigger than the Kaminsky DNS Vuln.
Speaking of Dan, he loves Securabit!

Audio Steganography
Hiding information by slightly altering the binary sequence of a sound file
From simple algorithms that insert info in the form of signal
noise, to more powerful methods that exploit sophisticated signal
processing techniques to hide information.
LSB coding (least significant bit):  substitute with a binary msg
Parity coding
Phase coding:  #  The original sound signal is broken up into
smaller segments whose lengths equal the size of the message to be
encoded.
A Discrete Fourier Transform (DFT) is applied to each segment to create a matrix of the phases and Fourier transform magnitudes.
Phase differences between adjacent segments are calculated.
Phase shifts between consecutive segments are easily detected.
In other words, the absolute phases of the segments can be changed but
the relative phase differences between adjacent segments must be
preserved. Therefore the secret message is only inserted in the phase
vector of the first signal segment as follows:
Spread spectrum
Two versions of SS can be used in audio steganography: the
direct-sequence and frequency-hopping schemes. In direct-sequence SS,
the secret message is spread out by a constant called the chip rate and
then modulated with a pseudorandom signal. It is then interleaved with
the cover-signal. In frequency-hopping SS, the audio file's frequency
spectrum is altered so that it hops rapidly between frequencies.

Forensic recovery on SSD
SSD Forensics:
- no physical security hooks that prevent them from being removed from enclosures
- ultraviolet laser to wipe out lock bits (encryption) from fuses on chips that secure SSDs
- overall easier to erase data on SSD (with encryption)
vs HDD Forensics:
- Harder to fully erase data 9have to overwrite or physically damage)
- easier to fully encrypt
Jim handy: hacker could easily unsolder NAND chips from an SSD
and read the data using a flash chip programmer, then reassembled using
data recovery software.
SSDs are hot, but not without security risks
