keimpx – Open Source SMB Credential Scanner

keimpx is an open source tool, released under a modified version of Apache License 1.1. It can be used to quickly check for the usefulness of credentials across a network over SMB. Credentials can be:

• Combination of user / plain-text password.
• Combination of user / NTLM hash.
• Combination of user / NTLM logon session token.

If any valid credentials has been discovered across the network after its attack phase, the user is asked to choose which host to connect to and which valid credentials to use, then he will be prompted with an interactive SMB shell where the user can:

• Spawn an interactive command prompt.
• Navigate through the remote SMB shares: list, upload, download files, create, remove files, etc.
• Deploy and undeploy his own service, for instance, a backdoor listening on a TCP port for incoming connections.
• List users details, domains and password policy.

Medusa 2.0 – Parallel Network Login Brute Forcing Tool

What is Medusa? Medusa is a speedy, massively parallel, modular, login brute-forcer for network services created by the geeks at Foofus.net.

It currently has modules for the following services: AFP, CVS, FTP, HTTP, IMAP, MS-SQL, MySQL, NCP (NetWare), NNTP, PcAnywhere, POP3, PostgreSQL, rexec, rlogin, rsh, SMB, SMTP (AUTH/VRFY), SNMP, SSHv2, SVN, Telnet, VmAuthd, VNC. It also includes a basic web form module and a generic wrapper module for external scripts.

Features

• Thread-based parallel testing. Brute-force testing can be performed against multiple hosts, users or passwords concurrently.
• Flexible user input. Target information (host/user/password) can be specified in a variety of ways. For example, each item can be either a single entry or a file containing multiple entries. Additionally, a combination file format allows the user to refine their target listing.
• Modular design. Each service module exists as an independent .mod file. This means that no modifications are necessary to the core application in order to extend the supported list of services for brute-forcing.

This release contains the most significant changes to the core of Medusa since its original release in 2005. We’ve moved to a “real” thread pool and modified how credential sets are selected. For a more detailed list of changes check the ChangeLog here.

While Medusa was designed to serve the same purpose as THC-Hydra, there are several significant differences. For a brief comparison see Medusa Compare.

GreenSQL – Open Source Database Firewall Software

GreenSQL is an Open Source database firewall used to protect databases from SQL injection attacks. GreenSQL works as a proxy for SQL commands and has built in support for MySQL & PostgreSQL . The logic is based on evaluation of SQL commands using a risk scoring matrix as well as blocking known db administrative commands (DROP, CREATE, etc). GreenSQL is distributed under the GPL license.

GreenSQL Architecture

GreenSQL works as a reverse proxy for MySQL connections. This means, that instead of connecting TO THE MySQL server, your applications will connect to THE GreenSQL server. GreenSQL will analyze SQL queries and then, if they’re safe, will forward them to the back-end MySQL server.

New Changes

In this version, GreenSQL provides native support for PostgreSQL (http://www.postgresql.org) databases for the very first time. In fact, GreenSQL is the only database firewall (Open or Closed Source) available for the protection of the many PostgreSQL databases currently in use.

GreenSQL 1.2 merges the GreenSQL-Console package into the GreenSQL-FW. The GreenSQL-Console will no longer be released as a separated package. During the installation process, you will be able to choose whether or not to install the console.

You can download GreenSQL v1.2 here:

SecuBat – Modular Web Vulnerability Scanner

As the popularity of the web increases and web applications become tools of everyday use, the role of web security has been gaining importance as well. The last years have shown a significant increase in the number of web-based attacks. For example, there has been extensive press coverage of recent security incidences involving the loss of sensitive credit card information belonging to millions of customers.

Typical web application security vulnerabilities result from generic input validation problems. Examples of such vulnerabilities are SQL injection and Cross-Site Scripting (XSS). Although the majority of web vulnerabilities are easy to understand and to avoid, many web developers are, unfortunately, not security-aware. As a result, there exist many web sites on the web that are vulnerable.

SecuBat is a generic and modular web vulnerability scanner that, similar to a port scanner, automatically analyzes web sites with the aim of finding exploitable SQL injection and XSS vulnerabilities.

Software Requirements

• Windows 2000, XP, 2003 or higher
• .NET Framework 2.0 or higher
• MS SQL Server 2000, 2005, Express, MSDE or higher

Known Issues

• If you schedule a crawling run, you have to restart SecuBat for manually selecting this crawling run for
  an attacking run afterwards if you not choose to do a combined run.
• The XSS variants report a not existing vulnerability if the response page contains the injected string within the title tag.
• The “Attack Report” window shows only attacks with an analysis value greater than 0 (indicating a vulnerability).

Nmap v5.20 – Open Source Network Exploration & Auditing Tool

For those that may not know, Nmap (“Network Mapper”) is a free open source utility for network exploration or security auditing. It was designed to rapidly scan large networks, although it works fine against single hosts. Nmap uses raw IP packets in novel ways to determine what hosts are available on the network, what services (application name and version) those hosts are offering, what operating systems (and OS versions) they are running, what type of packet filters/firewalls are in use, and dozens of other characteristics.

Nmap 5.20 offers more than 150 significant improvements, including:

• 30+ new Nmap Scripting Engine scripts
• Enhanced performance and reduced memory consumption
• Protocol-specific payloads for more effectie UDP scanning
• A completely rewritten traceroute engine
• Massive OS and version detection DB updates (10,000+ signatures)

You can download Nmap 5.21 here (more options):

Linux – nmap-5.21.tgz
Windows – nmap-5.21-win32.zip
