chntpw (v. 0.99.2 040105 ) [7] chntpw is a Linux utility to (re)set the password of any user that has a valid (local) account on your WinNT or Win2000 system, by modifying the crypted password in the registry's SAM file. You do not need to know the old password to set a new one. It works offline (i.e., you have to shutdown your computer and boot off a linux floppy disk). The bootdisk includes stuff to access NTFS partitions and scripts to glue the whole thing together. This utility works with SYSKEY and includes the option to turn it off. A bootdisk image is provided.

Clamav (v. 0.88.4 ) [8] Anti-Virus program.

foremost (v. 1.3 ) [17] Foremost is a console program to recover files based on their headers, footers, and internal data structures. This process is commonly referred to as data carving. Foremost can work on image files, such as those generated by dd, Safeback, Encase, etc, or directly on a drive. The headers and footers can be specified by a configuration file or you can use command line switches to specify built-in file types. These built-in types look at the data structures of a given file format allowing for a more reliable and faster recovery.

ftimes (v. 3.4.0 ) [18] FTimes is a system baselining and evidence collection tool. The primary purpose of FTimes is to gather and/or develop topographical information and attributes about specified directories and files in a manner conducive to intrusion and forensic analysis.

Galleta is built to work on multiple platforms and will execute on Windows (through Cygwin), Mac OS X, Linux, and *BSD platforms.

Gcombust - Graphical CD Burner (v. 0.1.55-2 ) [20] gcombust is a GTK+ frontend for mkisofs, mkhybrid, cdrecord, and cdlabelgen. It has primitive support for controlling the directory (root) structure and size of an image without copying files/symlinking or writing 10 lines of arguments. It can also maximize disk usage by hinting at which directories/files to use.

GHex (v. 2.8.1 ) [21] GHex is a simple binary editor. It lets users view and edit a binary file in both hex and ascii with a multiple level undo/redo mechanism. Features include find and replace functions, conversion between binary, octal, decimal and hexadecimal values, and use of an alternative, user-configurable MDI concept that lets users edit multiple documents with multiple views of each.

GQView (v. 2.0.1 ) [22] An image browser that features single click access to view images and move around the directory tree.

Graveman - Graphical CD Burner (v. 0.3.12-4-2.1 ) [23] GRAVEMAN is a GUI frontend for CD-R tools (cdrecord, readcd, and mkisofs), cdrdao, DVD+RW tools (growisofs and dvd+rw-format), and sox. It allows you to burn audio CDs (from WAV, Ogg, MP3, or FLAC files) and data CDs or DVDs, and allows you to duplicate CDs.

grepmail (v. 5.3032 ) [24] grepmail searches a normal or compressed mailbox (gzip, bzip2, or tzip) for a given regular expression and returns those emails that match the query. It also supports searches constrained by date and size.

LinEn (v. 5.05f ) [25] EnCase also has developed a method of acquisition with Linux machines or "Linen" (EnCase for Linux), and the interface is similar to that of EnCase for DOS but of course the process is completely different from EnCase for DOS.

md5deep Suite (v. 1.12) [26] md5deep is a cross-platform set of programs to compute MD5, SHA-1, SHA-256, Tiger, or Whirlpool message digests on an arbitrary number of files. The programs run on Windows, Linux, Cygwin, *BSD, OS X, Solaris, and should run on most other platforms. md5deep is similar to the md5sum program found in the GNU Coreutils package.

mac_grab (v. 1.0 ) [27] e-fense created program to grab all of the MAC times from a system.

Magicrescue (v. 1.1.4 ) [28] Magic Rescue scans a block device for file types it knows how to recover and calls an external program to extract them. It looks at "magic bytes" in file contents, so it can be used both as an undelete utility and for recovering a corrupted drive or partition. As long as the file data is there, it will find it. It works on any file system, but on very fragmented file systems it can only recover the first chunk of each file. Practical experience (this program was not written for fun) shows, however, that chunks of 30-50MB are not uncommon.

NTFS-3G (v. 2006-08-22-BETA ) [29] Finally Linux has got full read-write open source NTFS support! Preliminary benchmarks show that the still unoptimized driver already sometimes twice as fast as ext3 and 20-50 faster than the commercial Paragon NTFS. Interestingly Captive NTFS, which uses the native Windows NTFS driver, fails all benchmarks with file loss.

You can reduce the capture size. Auto-generate filename option will add the time stamp (date/time) to your filename in order to be able to take several captures without having to change the filename. Optional sound when capture is done.

IECookiesView (v. 1.70 ) [56] IECookiesView is a small and handy utility that displays the details of all cookies that IE stores on your computer. In addition, it allows you to sort the cookies, delete selected ones, and view detailed information about each one and even save the cookies to a readable text file. If you are connected to a network, you can watch the cookies of other computers, as long as you have a read permission on the cookies folder and under Windows 2000, you can view the cookies of other users (admin rights). IECookiesView also allows you to view references to deleted cookies that are still stored in the index.dat file.

IEHistoryView (v. 1.32 ) [57] IEHistoryView allows you to view and modify the history of visited websites in Internet Explorer. In addition, you can also export all or selected items to HTML reports, view detailed properties for selected entries, sort them and more. The program allows you to access the history of other user accounts or network computers as well, provided that you have the proper access rights.

IRCR (v. 2.3 ) [58] The Incident Response Collection Report is a script to call a collection of tools that gathers and/or analyzes data on a Microsoft Windows system. You can think of this as a snapshot of the system in the past. Most of the tools are oriented towards data collection rather than analysis.

Process Explorer (v. 10.2 ) [67] The Process Explorer display consists of two sub-windows. The top window always shows a list of the currently active processes, including the names of their owning accounts, whereas the information displayed in the bottom window depends on the mode that Process Explorer is in: if it is in handle mode you'll see the handles that the process selected in the top window has opened; if Process Explorer is in DLL mode you'll see the DLLs and memory-mapped files that the process has loaded. Process Explorer also has a powerful search capability that will quickly show you which processes have particular handles opened or DLLs loaded.

Protected Storage PassView (v. 1.63 ) [68] Protected Storage PassView is a small utility that reveals the passwords stored on your computer by Internet Explorer and Outlook Express. The passwords are revealed by reading the information from the Protected Storage.

This utility can only show the passwords of the current logged-on user, it cannot reveal the passwords of other users.

PsTools Suite (v. 2.34 ) [69] What sets these tools apart is that they all allow you to manage remote systems as well as the local one. The first tool in the suite was PsList, a tool that lets you view detailed information about processes, and the suite is continually growing. The "Ps" prefix in PsList relates to the fact that the standard UNIX process listing command-line tool is named "ps", so I've adopted this prefix for all the tools in order to tie them together into a suite of tools named PsTools. The tools included in the PsTools suite, which are downloadable individually or as a package, are: PsExec - execute processes remotely PsFile - shows files opened remotely PsGetSid - display the SID of a computer or a user PsKill - kill processes by name or process ID PsInfo - list information about a system PsList - list detailed information about processes PsLoggedOn - see who's logged on locally and via resource sharing PsLogList - dump event log records PsPasswd - changes account passwords PsService - view and control services PsShutdown - shuts down and optionally reboots a computer PsSuspend - suspends processes All of the utilities in the PsTools suite work on Windows NT, Windows 2000 and Windows XP.

Pst Password Viewer (v. 1.00 ) [70] The password encryption in the PST file is very weak, and for each password-protected PST file, there are many passwords that can open it. PstPassword provides 3 different passwords for each password-protected PST file. It's possible that one of them will be the original password that you typed, and it's also possible that none of these passwords will be identical to the original one. However, all 3 passwords provided by PstPassword will open the PST file without problems.

ptfinder (v. 2.0 ) [71] PTFinder searches a memory dump of a system running Microsoft Windows for traces of processes and threads. Some functional checks are also applied. PuTTY SSH Client (v. 0.58 ) [72] PuTTY is a free implementation of Telnet and SSH for Win32 and Unix platforms, along with an xterm terminal emulator.

reg (v. ) [73] Adds, changes, and displays registry subkey information and values in registry entries, for the Local User.

RegScanner (v. 1.30 ) [74] RegScanner is a small utility that allows you to scan the Registry, find the desired Registry values that match to the specified search criteria, and display them in one list. After finding the Registry values, you can easily jump to the right value in RegEdit, simply by double-clicking the desired Registry item. You can also export the found Registry values into a .reg file that can be used in RegEdit.

ReSysInfo (v. 2.1 ) [75] ReSysInfo is a system information viewer for Windows. The tool has 25 total information modules: BIOS information, CMOS, desktop, DirectX, drives, environment, fonts, keyboard, locale, machine & APM, mainboard, MCI, memory, mouse, multimedia, network, OpenGL, passwords, ports, printers & fax, processes, processor, video system, general information about Windows and a summary. ReSysInfo has a Report Wizard which can export the information to 3 different formats: plain text, HTML and XML.

rifiuti (v. 1.0 ) [76] Rifiuti will parse the information in an INFO2 file and output the results in a field delimited manner so that it may be imported into your favorite spreadsheet program. Rifiuti is built to work on multiple platforms and will execute on Windows (through Cygwin), Mac OS X, Linux, and *BSD platforms.

Rootkit Revealer (v. 1.7 ) [77] Rootkit Revealer is an advanced rootkit detection utility. It runs on Windows NT 4 and higher and its output lists Registry and file system API discrepancies that may indicate the presence of a user-mode or kernel-mode rootkit. Rootkit Revealer successfully detects all persistent rootkits published at www.rootkit.com, including AFX, Vanquish and HackerDefender (note: Rootkit Revealer is not intended to detect rootkits like Fu that don't attempt to hide their files or registry keys). If you use it to identify the presence of a rootkit please let us know!

Secreport (v. 3.27.07 ) [78] It is a small suite of two command-line tools for collecting security-related information from Windows-based system (SecReport) and comparing any two reports either from any two systems or from same system after some time (Delta). I use these tools to quickly assess level of securing of Windows system and to compare results to baseline. The tools are useful both in daily security administration and during incident responce - for fast collection of information. Tools do not need to be installed on system and can be run directly from hard or CD-R disk or network drive (mapped or UNC). Format of reports - XML. Reports can be viewed with IE 6.0 browser. MD5 hash file for report automatically created.

WFT (v. 2.0 ) [79] The Windows Forensic Toolchest (WFT) was written to provide an automated incident response [or even an audit] on a Windows system and collect security-relevant information from the system. It is essentially a forensically enhanced batch processing shell capable of running other security tools and producing HTML based reports in a forensically sound manner. A knowledgeable security person can use it to help look for signs of an incident (when used in conjunction with the appropriate tools). WFT is designed to produce output that is useful to the user, but is also appropriate for use in court proceedings. It provides extensive logging of all its actions along with computing the MD5 checksums along the way to ensure that its output is verifiable. The primary benefit of using WFT to perform incident responses is that it provides a simplified way of scripting such responses using a sound methodology for data collection.

Winaudit (v. 2.15 ) [80] WinAudit is easy to use; no special knowledge is required to use the program. It is a self-contained single file that needs no installation or configuration. It can be run from a floppy disk or USB stick. Simply download the program and double click on it. User interface translations have been kindly contributed by several people; if possible WinAudit will automatically start in your language. The program reports on virtually every aspect of computer inventory and configuration. Results are displayed in web-page format, categorized for ease of viewing and text searching. Whether your interest is in software compliance, hardware inventory, technical support, security or just plain curiosity, WinAudit has it all. The program has advanced features such as service tag detection, hard-drive failure diagnosis, network port to process mapping, network connection speed, system availability statistics as well as Windows® update and firewall settings.
