GSM A5 Cracking topic is started to be public material since The Hacker Choice disclosed their research. Many open source materials related to GSM are released to the public on Osmocomm. Now, tool called Kraken is freely distributed on internet to crack GSM A5.

I am pleased to announce the first release of a A5/1 cracker capable
using the full Berlin set of rainbow tables for lookups. I have named
this beast Kraken, after a Norse mythological creature capable of eating
many things for breakfast. Kraken feeds of an exclusive diet of A5/1
encrypted data.

Currently only a bare bone functionality is present, but the UI will be
improved, with the specific goal of providing an easy to use tool for
cracking GSM intercepts. But setting up this Leviathan can a bit
cumbersome, so I will give a short howto here:

Prerequisites:

* Linux machine, multicore min 3GB RAM
* 1.7 - 2TB of HD partitions without filsystem ( ex Samsung spinpoint F3s,
  with 4k aligned start of partition )
* The Berlin A5/1 Rainbow table set
* GPU support will be added for ATI Radeon HD

Setup:

Find out how many tables you want on each partition, (usually roughly
equal on each) and make the initial configuration file. An example
configuration folder can be found in tinkering/A5Util/indexes. This
folder should contain a tables.conf file. The example files shows a
setup of 4 disk having 10 tables each. The index files for the various
tables will be added to the index folder as they are written to disk.
The first section of the config file needs to be set up with the list of
available partitions, and the number of tables that each partition
should hold. A single table needs 42GB of space. (Do NOT change the
order of this section)

For safety reasons it is best not to build the tables running as root.
The you will then have to make your table partitions user accessible.
Add a file such as 10-disk.rules in /etc/udev/rules.d with one line for
each partition:

KERNEL=="sda1", OWNER="frank"

Then manually change the ownership of the device nodes with chown. Take
care when doing this, as you do not want to nuke any of your system
partitions.

Add tables to your disk array:

First build and make a symlink from your index folder to the
TableConvert tool. It is assumed that the Berlin tables are available in
either SSD or index free delta format. The python script Behemoth.py
will recursively search for tables, and add them to the disk array and
configuration file as needed. (Duplicates will not be added) - This
operation(s) will take some hours to complete, but when done you should
end up with a tables.conf file listing ~40 tables, their advance
parameter (id), which device they reside on, and a block offset into the
device.

Build and fire up Kraken:

./kraken path_to_index_folder

Currently it will only load up all tables, and crack TDMA burst 998 for
the challenge data. This takes 1.5 minutes on a 4 core Phenom II using
only CPU power, and the output should look like:

Cracking
001101110011000000001000001100011000100110110110011011010011110001101010100100101111111010111100000110101001101011
Found de6bb5e60617f95c @ 12
Found 6fb7905579e28bfc @ 23

A more interactive UI with appropriate data formats (representations)
will be added for easy interfacing with airprobe. Optional GPU support
will also be added for faster cracking time.

cheers,
Frank

It’s easy to intercept data communication inside linux/unix environment since there are so many tools to help us. We have tcpdump, wireshark, ettercap, dsniff, and still many others. But, can you imagine how to sniff data flows trough router? If our router are Juniper family, then we are lucky enough because Juniper has internal command which works like tcpdump on unix/linux system. For example, we can use this following command to sniff traffic on Juniper interface ge-0/0/0.0

monitor traffic interface ge-1/0/0.0 detail no-resolve
monitor traffic interface ge-1/0/0.0 detail no-resolve print-ascii print-hex

These two commands will work in Juniper like tcpdump in linux/unix below:

tcpdump -nev -i ge-1/0/0.0
tcpdump -nev -X -i ge-1/0/0.0

But remember, ge-1/0/0.0 interface is not known in linux/unix so that’s why you have to change this with Network Interface Card (NIC) in linux/unix. Then, how if our router is not Juniper family? Here, i’ll write my experience in sniffing inside Cisco router which’s known as the most popular router over the world.

GridSphere is web based portal framework to access grid computing resources. The GridSphere provides an open-source portlet based Web portal. GridSphere enables developers to quickly develop and package third-party portlet web applications that can be run and administered within the GridSphere portlet container.

GridSphere which is critically uses to access grid resource is found to be vulnerable that can be exploited to enumerate a user is valid or not in grid. This vulnerability exist due to the response of gridsphere in handling in-exist user with “User does not exist“. To exploit this issue, you can use this python script.

python gridsphere-brute.py https://example.com/acgt/portal?cid=login users.txt

IPSECS has developed some tools to assess grid computing security years ago which can be download here. The tools is encoded in ASCII and bundled with article which explains grid computing [in]security written in indonesian. The tools provided can be used to:

• Enumerate headnode by identifying GridFTP Service and Web Service Container
• Crack private key in Certificate Authority
• Exploit others headnode in grid when a headnode and its certificate compromised.

For your information, currently IPSECS is developing grid-toolkit to make grid computing penetration much more easier.

Have you ever thought to put your ads in compromised website? Have you ever done to modify someone ads with your own? Putting your ads in someone website will not help increasing your revenue in low-traffic website.

Have you ever thought to insert malware in compromised website and exploit their clients? yeah browser vulnerability is the answer! Inserting in low-traffic website will not really help spreading your malware and compromise their clients!

Now, even this is old for us (IPSECS), we release tool to identify trafffic rank based on Alexa. This tool will help you to identify Alexa Rank on massive collected domains. By knowing the traffic rank of domains, this tool helps you to decide if website is worth or not if you put your ads on them. By knowing the traffic rank of domains, you can know if website is potential or not in boosting your revenue. Our simple tool need some perl module to be installed:

• strict
• warnings
• Switch
• POSIX
• LWP::UserAgent
• HTTP::Message

Lastly, you can download our tool to help indentifying traffic here. Cheat the ads for your profit, Boost your revenue now!

IPv6 is future protocol internet with rich of security features but hackers always do research and try to exploit it. Times by times, days by days, papers and presentations which explains who to defeat this protocol are widely published. Van Hauser of The Hacker Choice (THC) releases his IPv6 attack toolkit to exploit IPv6 protocol weakness. His tools can be freely downloaded on THC website. HD Moore, author Metasploit project wrote paper about Exploiting Tomorrow’s Internet Today: Penetration testing with IPv6 which can be read on http://uninformed.org. His paper tells us about exploiting  IPv6 applications by proxying/relaying via IPv4.

IPSECS, unofficially releases his IPv6 Hackit on sourceforge and papers which nearly complete explains IPv6 exploitation. His papers content of :

• Introduction to IPv6
• Connecting to IPv6 Backbone (IPv6-in-IPv4 Tunneling using TSP)
• An Introduction to IPv6 Socket Programming
• IPv6 Discovery & Scanning (via ICMP, TCP, DNS)
• Writing IPv6 Remote Exploit & Shellcoding (Stack Based Buffer Overflow, Format String)
• IPv6 Protocol Vulnerability (Man In The Middle, Denial of Service)

You can freely download this paper on core.ipsecs.com written in Indonesian. IPSECS wrote IPv6-Hackit using Perl Scripting Language which means that the tools don’t need to be compiled. Somehow, this tool needs some perl module to be installed:

• strict
• warnings
• Switch
• English
• Net::DNS
• POSIX
• Getopt::Long
• LWP::UserAgent
• HTTP::Message
• IO::Socket::INET6

This tool supports to do:

• Hosts Enumeration finding which host is up/down.
• TCP Port scanning to find which port is open/close.
• Googling via unix shell to find possible IPv6 domains.
• Finding AAAA IPv6 host record from single or massive collected domains.
• Getting shell from IPv6 binding shellcode/payload.
• Getting shell from IPv6 reverse shellcode/payload.
• Exploiting simple IPv6 application weakness (currently this module is still developed)
• IPv6 Binding backdoor with authentication (currently this module is still developed)

You can easily download this IPv6 Hackit on ipv6hackit.sourceforge.net. Meanwhile you play this tools and read the paper, now we develope grid-toolkit to be released soon. So just follow and watch this website, IPSECS just gives best stuff to play with! Finally enjoy guys!

One year after his Black Hat talk on Automated Teller Machine security vulnerabilities was yanked by his employer, security researcher Barnaby Jack plans to deliver the talk and disclose a new ATM rootkit at the computer security conference.

He plans to give the talk, entitled “Jackpotting Automated Teller Machines,” at the Black Hat Las Vegas conference, held July 28 and 29.

Jack will demonstrate several ways of attacking ATM machines, including remote, network-based attacks. He will also reveal a “multi-platform ATM rootkit,” and will discuss things that the ATM industry can do to protect itself from such attacks, he writes in his description of the talk, posted this week to the Black Hat Web site.

Jack was set to discuss ATM security problems at last year’s conference, but his employer, Juniper Networks, made him pull the presentation after getting complaints from an ATM maker that was worried that the information he had discovered could be misused.

The security researcher found a straightforward way of getting around Juniper’s objections, however. Last month, he took a new job as director of security research with IOActive.

ATM machines do get compromised, but in a roundabout way. Thieves often hit them by installing card skimmers on them to extract magnetic stripe data from the cards. Then, using a hidden video camera, they steal login numbers. Using all of this information, the crooks can build their own duplicate cards and empty bank accounts.

But Jack’s talk looks at a new area: bugs in the software used to run the machines.

He’s taken advantage of the extra year provided by Juniper’s ban to do more research. “Last year, there was one ATM; this year, I’m doubling down and bringing two new model ATMs from two major vendors,” Jack says in his talk description. The security researcher couldn’t immediately be reached for comment.

Jack doesn’t say which ATMs he plans to discuss, but it could be any major vendor, according to Black Hat Director Jeff Moss. “He’s got a living room full of a lot of different brands of ATMs, and they all seem to suffer from one or the other problem,” he said.

ATMs haven’t received a lot of serious scrutiny by security researchers, so Jack’s talk will break new ground, Moss said. “Apparently you can make all the money come out,” he said.

Computer forensics is part of information security in finding legal evidence on computers and digital storage media. You can find more about forensics resource on internet which some of them are free, yeah it’s free!

We have Open Source Computer Forensics Manual at http://oscfmanual.sourceforge.net. We also have cool article (book) entitled with “Forensic Discovery” at http://www.porcupine.org/forensics/ which published freely and completed with some tools. You can follow  http://blogs.sans.org/computer-forensics/ or read First Responders Guide to Computer Forensics at CERT.

Finally, you can download some free book about forensics and information security here.

PHPNuke is old and mature Content Management System (CMS), but once again hacker proofes us that’s nothing 100% secure. Its maturity doesn’t guarantee its security, PHPNuke is vulnerable to remote code execution which can be exploited to compromise apache user.

Most fearsome statement from the author of the exploit is that about wormable remote code execution in PHPNuke. Since PHPNuke is one of the most popular CMS used by many webmasters, then how many sites will be compromised? Well then, just take the proof of concept here.

Network admins prepare for internet security upgrade.

Network administrators are being encouraged to run some last minute checks on their DNS servers, routers and firewalls before the final cluster of the internet’s root servers are loaded up with the DNSSEC security upgrade tomorrow night.

As reported late last week on iTnews.com.au, from May 5 the DNSSEC upgrade will attach a digital signature to every response from the root servers where the DNS resolver is configured to request signed answers (via setting the DO bit in the Extensions to DNS - EDNS settings) to requests for an internet page, in order to provide an additional layer of assurance for internet users that they are connecting to the correct page.

Concerns have been raised that the upgrade might cause some problems for network administrators working with older networking equipment that is preconfigured to either not accept DNS responses over 512 bytes or not accept DNS responses split into several packets using the TCP protocol.

ICANN’s latest update on the upgrade, released yesterday, confirmed that root server cluster ‘J-Root’ is the last of 13 root server clusters to transition to DNSSEC on May 5 at 1700 - 1900 UTC.

This is really old archive, it’s almost three years since January 2007. But, i guess this will really be useful to start learning. Check this out.

Can you imagine our indonesian internet core routing to be shutted down? None can browse their email, open facebook, or just search through google. Can you imagine indonesian internet banking stopped working for a while? Automatic Teller Machine (ATM) won’t work to response your request? That’s all just the lowest risk when core routing to be compromised.

Can you imagine when your confidential data to be sniffed without none notice it? Can you imagine when your username and password to be stealed? Oh that’s not big deal huh? But try to imagine your banking transaction to be intercepted and modified, yeah that’s the real fear on digital world. Hell yeah, this paper explains you how that problems are possible. This paper try to tell you how weak our indonesian core routing infrastructure, check it out!

The latest version of freebsd is found to be vulnerable. This vulnerability is found in run time link editor (rtld) which can be tricked to accept LD variables even on setugid binaries. You might see this flaw by analyzing this exploit.

With this leaked exploit, it’s more than 10 exploitable vulnerability leaked to public this year (2009)! So it’s that true if freebsd as secure as what people said?!

Thinking how to backdoor & keylog website in unusual way is something that fun to be implemented. Kiddies usually use public backdoor to come back to compromised server or website, dumping the database, and cracking hash of confidential information likes password and CC number. Public backdoor is somewhat easy to be detected by administrator while hash cracking sometimes gives no result.

Modifying source code of website to be a backdoor and keylogger is not kind of new technique, but just few kiddies know about this. By modifying the source code, we can make more invisible backdoor than using public ones. We also can record confidential information likes password and CC number in plaintext, so we don’t have to crack it. I have implemented this technique in phpbb3, modifying its source code become backdoor & keylogger. This concept can be used to modify ecommerce application so just try to imagine when your CC number being stolen.

Download my paper, presentation, and phpbb3 patch which has been presented in STIMIK Palcomtech Palembang.
