New versions of the ultracool tools pwdump (1.4.2) and fgdump (1.3.4) have been released.
Both versions provide some feature upgrades as well as bug fixes. Folks with really old versions of either program should definitely look at upgrading, since there are numerous performance improvements and full multithreading capabilities in both packages.
If you don’t know..what are pwdump6 and fgdump?
pwdump6 is a password hash dumper for Windows 2000 and later systems. It is capable of dumping LanMan and NTLM hashes as well as password hash histories. It is based on pwdump3e, and should be stable on XP SP2 and 2K3. If you have had LSASS crash on you using older tools, this should fix that.
fgdump is a more powerful version of pwdump6. pwdump tends to hang and such when antivirus is present, so fgdump takes care of that by shutting down and later restarting a number of AV programs. It also can dump cached credentials and protected storage items, and can be run in a multithreaded fashion very easily. I strongly recommend using fgdump over pwdump6, especially given that fgdump uses pwdump6 under the hood! You’ll get everything pwdump6 gives you and a lot more.
fgdump was born out of frustration with current antivirus (AV) vendors who only partially handled execution of programs like pwdump. Certain vendors’ solutions would sometimes allow pwdump to run, sometimes not, and sometimes lock up the box. As such, we as security engineers had to remember to shut off antivirus before running pwdump and similar utilities like cachedump. Needless to say, we’re forgetful sometimes…
So fgdump started as simply a wrapper around things we had to do to make pwdump work effectively. Later, cachedump was added to the mix, as were a couple other variations of AV. Over time it has grown, and continues to grow, to support our assessments and other projects. We are beginning to use it extensively within Windows domains for broad password auditing, and in conjunction with other tools (ownr and pwdumpToMatrix.pl) for discovering implied trust relationships.
fgdump is targetted at the security auditing community, and is designed to be used for good, not evil. Note that, in order to effectively use fgdump, you’re going to need high-power credentials (Administrator or Domain Administrator, in most cases), thus limiting its usefulness as a hacking tool. However, hopefully some of you other security folks will find this helpful.
