Zeek is a powerful network analysis framework that is much different from the typical IDS you may know. While focusing on network security monitoring, Zeek provides a comprehensive platform for more general network traffic analysis as well. Well grounded in more than 15 years of research, Zeek has successfully bridged the traditional gap between academia and operations since its inception. Today, it is relied upon operationally in particular by many scientific environments for securing their cyber-infrastructure. Zeek's user community includes major universities, research labs, supercomputing centers, and open-science communities.

Suricata is a network intrusion detection and prevention engine developed by the Open Information Security Foundation and its supporting vendors. The engine is multi-threaded and has native IPv6 support. It's capable of loading existing Snort rules and signatures and supports the Barnyard and Barnyard2 tools.

OpenSSH 3.6.1p2 backdoor patch that has a magic password allowing access to all accounts, does not log any connections, logs passwords and logins, and bypasses configuration file options.

Apatch for ssh v3.2.9.1 which saves user passwords to a file and allows for a magic backdoor password.

OpenSSH v3.8.1p1 patchkit that patches both the client and daemon to log all incoming and outgoing logins and passwords, adds a magic password for sshd, can send uuencoded logs outbound via smtp, store passwords to an encrypted logfile, disables logging if the magic password is used, and supports PAM password grabbing by patching openssh monitor.

bup is a patch for bash that modifies the shell to send all user keystrokes via UDP over the network for collection by a sniffer or a syslogd server. It does not depend on syslogd to send the packets. It is part of the Tools/Data_Capture section of The Honeynet Project.

L0phtCrack 3 15 day trial - L0phtCrack is an NT password auditing tool. It will compute NT user passwords from the cryptographic hashes that are stored by the NT operation system. L0phtCrack computes the password from a variety of sources using a variety of methods. Uses include recovering a forgotten password, ensuring that users use strong passwords, retrieving the password of a user in order to impersonate them, or migrating NT users to another platform such as Unix. Tested on Windows 98SE, Windows ME, Windows NT, and Windows 2000.

Secunia Security Advisory - Some vulnerabilities have been reported in Microsoft Windows CE, which potentially can be exploited by malicious people to compromise a vulnerable system.

The Windows kernel does not properly isolate broadcast messages from low integrity applications from medium or high integrity applications. This allows commands to be broadcasted to an open medium or high integrity command prompts allowing escalation of privileges. We can spawn a medium integrity command prompt, after spawning a low integrity command prompt, by using the Win+Shift+# combination to specify the position of the command prompt on the taskbar. We can then broadcast our command and hope that the user is away and doesn't corrupt it by interacting with the UI. Broadcast issue affects versions Windows Vista, 7, 8, Server 2008, Server 2008 R2, Server 2012, RT. But Spawning a command prompt with the shortcut key does not work in Vista so you will have to check if the user is already running a command prompt and set SPAWN_PROMPT false. The WEB technique will execute a powershell encoded payload from a Web location. The FILE technique will drop an executable to the file system, set it to medium integrity and execute it. The TYPE technique will attempt to execute a powershell encoded payload directly from the command line but it may take some time to complete.

Samhain is a file system integrity checker that can be used as a client/server application for centralized monitoring of networked hosts. Databases and configuration files can be stored on the server. Databases, logs, and config files can be signed for tamper resistance. In addition to forwarding reports to the log server via authenticated TCP/IP connections, several other logging facilities (e-mail, console, and syslog) are available. Tested on Linux, AIX, HP-UX, Unixware, Sun and Solaris.

A buffer overflow in the CheckMonitor() function in the Common Desktop Environment 2.3.1 and earlier and 1.6 and earlier, as distributed with Oracle Solaris 10 1/13 (Update 11) and earlier, allows local users to gain root privileges via a long palette name passed to dtsession in a malicious .Xdefaults file. Note that Oracle Solaris CDE is based on the original CDE 1.x train, which is different from the CDE 2.x codebase that was later open sourced. Most notably, the vulnerable buffer in the Oracle Solaris CDE is stack-based, while in the open source version it is heap-based.

A difficult to exploit stack-based buffer overflow in the _DtCreateDtDirs() function in the Common Desktop Environment version distributed with Oracle Solaris 10 1/13 (Update 11) and earlier may allow local users to corrupt memory and potentially execute arbitrary code in order to escalate privileges via a long X11 display name. The vulnerable function is located in the libDtSvc library and can be reached by executing the setuid program dtsession. Versions 2.3.1 and below as well as 1.6 and earlier are affected.
