RELEASE UPDATE 08/2010:
----------------------
This exploit was created almost a year ago and wasnt modified from that time
whatsoever. The vulnerability itself is patched for a long time already so
i have decided to release this little exploit. You use it for your own
responsibility and im not responsible for any potential damage this thing
can cause. Finally i don't care whether it worked for you or not.

P.S the technique itself is described here:

For your information, two days later at 19th August 2010, Kingcope released root exploit for FreeBSD 8.x and 7.x by poisoning mbufs() function. You may download Kingcope’s exploit here. Now happy exploiting while waiting “SAHUR” guys!

Just like what we promised before, this time we want to release grid toolkit which usable to perform pentest against grid computing infrastructure. It’s almost two years after we release paper related to grid computing [in]security at 2008. The paper contains of:

• Introduction to grid computing
• Grid computing scanning and enumeration
• Exploiting network and transport layer related to grid security
• Exploiting DNS to stop grid infrastructure trusteeship
• Exploiting web based - grid computing portal
• Cracking certificate authority pass phrase
• Exploiting headnode trusteeship using XML file

Some points mentioned can be exploited using existing network security tool while others are already supported by Grid Toolkit. Grid Toolkit uses python with some additional module which must be installed. The additional python module are:

• Module goto to support grid toolkit core program
• Module ClientForm to support grid portal guessing
• Module Paramiko to support certificate authority cracking

Grid toolkit supports to:

• Scanning and enumeration grid infrastructure
• Guessing login gridsphere - web based grid portal
• Cracking pass phrase of certificate authority private key file
• Exploiting headnode trusteeship using XML file

More reference about how to install and use this tool will be available soon, so just keep in touch with IPSECS. Finally you can download grid toolkit on gridtoolkit.sourceforge.net or reading python source code on core.ipsecs.com!

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
0011011100110000000010000011000110001001101101100110110100111100011010
10100100101111111010111100000110101001101011
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.

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.

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!

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.

An independent security consultant publicized this week the details to a critical flaw in the server message block version 2 (SMB2) component of Microsoft’s Windows Vista, Windows Server 2008, and the release candidate for Windows 7.

The researcher, Laurent Gaffié, claimed in his advisory that the vulnerability causes a Blue Screen of Death, a pernicious crash on Windows system, but other researchers have subsequently concluded that the flaw is actually remotely exploitable, a more serious issue.

Microsoft acknowledged the flaw on Tuesday in an advisory. The flaw does not affect the latest version of Windows 7, Windows Server 2008 R2, nor Windows XP, the company stated. Microsoft took the researcher to task for disclosing the information before it fixed the security issue.

Yet, Gaffié argued that the disclosure was fair. The software company should have done more software quality assurance (SQA) on the networking components, he said in an e-mail interview with SecurityFocus. If they did, they would have easily found the issue — it took his fuzzer only 15 packets to crash the component, he said.

“So I personally think the one who has been irresponsible is Microsoft for shipping this driver on any Server 2008, Vista, and Windows 7 (system) without doing any SQA and security review,” he responded.

Gaffié said he notified the company, but had a typo in the e-mail address.

The flaw was disclosed on Monday, the day before Microsoft’s regularly scheduled patch day. The software giant issued five patches for eight vulnerabilities, including three flaws in the company’s TCP/IP networking stack. Other flaws affected Windows’ Javascript engine and its Windows Media components.

While Microsoft has not released a fix for the issue, the software giant recommended that administrators disable SMB version 2 or block the specific TCP ports (139 and 445) used by the file-sharing feature.

Yupe, that’s true when sock_sendpage() is discovered to be vulnerable by Tavis Ormandy and Julien Tinnes. The function is vulnerable to NULL pointer dereference that can be exploited to escalate priviledge to be root. Most of linux kernel are reported to be vulnerable. Exploit to take advantage of this flaw has been developed and spreaded freely on internet. The exploit can be used to bypass security restriction like SElinux.

http://milw0rm.com/exploits/9435 - the first written exploit by spender of gresecurity
http://milw0rm.com/exploits/9436 - another exploit taken from www.frasunek.com
http://milw0rm.com/exploits/9479 - another exploit from p0c73n1
http://milw0rm.com/exploits/9545 - another exploit written by Ramon de Carvalho Valle of risesecurity

Download the exploit, compile and execute! BOOMMM It’s root! Finally, this post is a little bit late :D.

It just fun to try exploiting pulseaudio to gain root priviledge, well my Ubuntu Intrepid is indeed exploitable.

Searching more about linux, i find an exploit to attack RHEL family with SELinux enabled here. So, is that true linux more secure than windows?? The fact which makes linux more secure is the people behind the machine. So many linux administrators is much more skilled than windows ones.

DEFINITION
Anti-forensics has only recently been recognized as a legitimate field of study. Within this field of study, numerous definitions of anti-forensics abound. One of the more widely known and accepted definitions comes from Dr. Marc Rogers of Purdue University. Dr. Rogers uses a more traditional “crime scene” approach when defining anti-forensics. “Attempts to negatively affect the existence, amount and/or quality of evidence from a crime scene, or make the analysis and examination of evidence difficult or impossible to conduct”.

A more abbreviated definition is given by Scott Berinato in his article entitled, The Rise of Anti-Forensics. “Anti-forensics is more than technology. It is an approach to criminal hacking that can be summed up like this: Make it hard for them to find you and impossible for them to prove they found you.” Interestingly, neither author takes into account using anti-forensics methods to ensure the privacy of one’s personal data.

Sub-Categories
Anti-forensics methods are often broken down into several sub-categories to make classification of the various tools and techniques simpler. One of the more widely accepted subcategory breakdowns was developed by Dr. Marcus Rogers. He has proposed the following sub-categories, data hiding, artifact wiping, trail obfuscation and attacks against the CF (computer forensics) process/tools.

This is my presentation in STIMIK Dipanegara Makasar. I try to describe Web and Wireless exploitation conceptually & technically. This presentation consist of:

• Web Hacking; I try to describe top 3 web exploitation, SQL Injection, File Inclussion, and Cross Site Scripting (XSS). My explanation are including SQL injection in login form, SQL injection in URI parameter, Local File Inclussion, Remote File Inclussion, DOM based XSS, Non-persistent XSS, and persistent XSS.
• Wireless hacking; I try to describe how to do war driving and how to exploit wireless network. Exploiting wireless network includes how to spoof MAC address, creating Rogue AP, Cracking WEP, Cracking WPA-PSK, and Denial of Service (DoS).

This presentation is not including how to defend that kind of attacking, but i’m sure this presentation is cool enough to start learning Web & Wireless Hacking. Download my presentation here.
