Man this blows. It seems it happened quite a while ago, I only just found out about it recently though when I was checking to see if L0phtcrack had been updated past version 5. Symantec has quietly pulled the plug on sales of L0phtCrack, the venerable password auditing and recovery application. The decision to discontinue […]

1. Nmap I think everyone has heard of this one, recently evolved into the 4.x series. 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 […]
Ophcrack is a Windows password cracker based on a time-memory trade-off using rainbow tables. This is a new variant of Hellman’s original trade-off, with better performance. It recovers 99.9% of alphanumeric passwords in seconds. We mentioned it in our RainbowCrack and Rainbow Tables article. Changes: (feature) support of the new table set (alphanum + 33 […]
Version 1.2 (Beta) of the pwdump6 software has been released. There are three major changes from the previous version: Uses “random” named pipes (GUIDs) to allow concurrent copies of the client to run. This is predominately for the next version of fgdump, which will be multithreaded. Will turn off password histories if the requisite APIs […]
The new “features” this time are primarily performance improvements possible due to the use of better algorithms (bringing more inherent parallelism of trying multiple candidate passwords down to processor instruction level), better optimized code, and new hardware capabilities (such as AltiVec available on PowerPC G4 and G5 processors). In particular, John the Ripper 1.7 is […]
What is RainbowCrack & Rainbow Tables? RainbowCrack is a general propose implementation of Philippe Oechslin’s faster time-memory trade-off technique. In 1980 Martin Hellman described a cryptanalytic time-memory trade-off which reduces the time of cryptanalysis by using precalculated data stored in memory. This technique was improved by Rivest before 1982 with the introduction of distinguished points […]
