Last week I gave a talk during the Password '13 security conference on various password analysis and pattern detection attacks using the Password Analysis and Cracking Kit. You can download slides for the presentation here.
The conference itself was an absolute blast with great organization by Per Thorsheim and Jeremi Gosney. The conference gathered a fascinating crowd which spawned hours of great discussions on password security, cryptography, politics and everything in between. However, I especially enjoyed meeting in real life with many members of Team Hashcat.
Team Hashcat had another great run at the CMIYC during Defcon where we placed 2nd. As always I ended up spending most of the conference in the hotel room or the chill room at Defcon, but that's part of the fun doing contests. Russia-based team Inside-Pro placed first by scoring more points on harder hashes, молодцы ребята!
Today, I have finally finished writing documentation for the many changes and adding the final polish to the next release of PACK 0.0.4. There should be noticeable performance bumps for all of the tools in the toolkit especially Rulegen which is now finally using multiple CPU cores. You should also try out the completely rewritten 'maskgen' which is now capable of generating highly optimized mask collections for use with Hashcat suite of tools (see presentation slides above for more details). Enjoy and most importantly have fun with password cracking! Read more.

PACK (Password Analysis and Cracking Toolkit) is a collection of utilities developed to aid in analysis of password lists and enhancing cracking of passwords using password pattern detection. It can be used to reverse word mangling rules, generate source words, optimize password masks, craft policy attacks, etc. for the Hashcat family of tools. The toolkit itself is not able to crack passwords, but instead designed to make operation of password crackers more efficient. Read more.
The field of password cracking has evolved by leaps an bounds over the last decade with the introduction of new cracking techniques, more advanced software and significantly faster hardware. One area which I find most fascinating is rule-based cracking. An attacker can develop a set of word mangling rules (e.g. substitute all 'a's to '@'s, upper-case every third letter, etc.) in order to attack non-random passwords which use slightly modified dictionary words. The purpose of this research is to develop an automated method of analyzing a large body of leaked passwords in order to come up with a list of frequently used words and rules to make up passwords.

DNSChef is a highly configurable DNS Proxy for Penetration Testers and Malware Analysts. It is capable of fine configuration of which DNS replies to modify or to simply proxy with real responses.
Version 0.2 introduces IPv6 support, large number of new DNS record types, custom ports and other frequently requested features. Read more.
The Sprawl is a research and development environment with a focus on information security and hacking culture. The site is split into several categories each containing unique presentation of the above topics.
is the main source for project announcements and site news. It is intentionally kept low volume so as not to distract from the rest of the site.
is a collection of articles covering a wide range of topics related to security. This is the product of my blood, sweat and tears navigating the rough waters of security research; I hope you will enjoy the fruits of my labor.
is a repository of security tools and scripts that rely heavily on topics covered in the research section. Each tool has detailed usage description; however, you might want to reference respective research article for in-depth understanding of its operation.
is a collection of media artifacts covering hacking culture. Currently it includes a few dozen handpicked documentaries and television shows on the subject. In case you are interested the name Simstim comes from William Gibson's The Sprawl trilogy. Simstim is described as a device capable of replaying or live viewing of another person's sensory experience. In a way this project attempts to stimulate your mind with a carefully selected collection of audio and video recordings.
is a historical project to explore events related to the hacking culture and information security such as group formations, important releases, compromises, arrests, etc. Studying the history of the previously mentioned topics is essential when trying to understand where we stand today and possibly glimpse into the future.
The site was designed and developed by Peter Kacherginsky (iphelix).
