Problem statement: Least Recently Used (LRU) is a common caching strategy. It defines the policy to evict elements from the cache to make room for new elements when the cache is full, meaning it discards the least recently used items first.

Hashcat is a popular password cracker and designed to break even the most complex passwords representation. To do this, it enables the cracking of a specific password in multiple ways, combined with versatility and speed.


Additionally, there are some GUI that makes hashcat easy to use. Hashview is one of the projects. This is a tool for security professionals to help organize and automate the repetitious tasks related to password cracking. In detail, it is a web application that manages Hashcat commands.


Password cracking is one of my favorite parts of information security. Many of us have built computer systems designed specifically for this task. We use tools like John the Ripper for quickie password cracking efforts and Hashcat for larger tasks but we usually sick these tools on cryptographic password hashes we obtain from hashdumps, database tables and tools such as Responder. One of the lessons we've learned from high profile breaches such as Sony is that it's extremely common for users and organizations to also store passwords in document formats such as Microsoft Word and Excel.


After you start cracking passwords, you'll probably get a strong, strong desire to start cracking them faster. The most common solution to this is to use a system with one or more graphics cards (GPUs) and use the GPUs to crack passwords instead of the computer's CPU. While the jumbo version of John does support GPUs, the most popular tool for GPU password cracking is Haschat. It's very well supported, constantly updated, free and can be downloaded from . As long as your video card drivers are up to date, Hashcat should automatically detect your GPU and use it for cracking.


Underneath the surface, password cracking requires a lot of math. Graphics cards are able to perform math functions like these at extremely high rates of speed. Because of this, a tool which utilizes GPUs can crack passwords MUCH faster than a CPU can. How much faster? I made a password protected .RAR file for a quick comparison.


These are all great options but we're burying the lead here. If we point Hashcat at a RAR file to crack, it will look at us confused and politely let us know that it doesn't see any hashes in the RAR file. There are isolated tools out there that will try to crack specific file types but we didn't build a GPU password cracking rig to not use its power to crack so how do we get a hash from the RAR file? The answer is John the Ripper. Well, not John himself, but his friends.


So while a lot of us have gone away from using John the Ripper in an effort to take advantage of the power of GPU password cracking, we can still use him when we're trying to get into password protected files that we commonly encounter on engagements.

The best way to learn anything is to simply follow in the footsteps of those who have done it successfully. And not just a few people, but thousands of interviewers, associates, engagement managers and consulting veterans who have successfully navigated this process and have gone on to lucrative careers across the top consulting firms.


"This guide is an accelerator for anyone preparing for management consulting case interviews. It is packed full of unique insights because it harvested contributions from recent MBA grads who succeeded through the case interview process and are now working at the best firms in the world! It's like getting coached by a ton of professional insiders - READ IT! I have a copy on my desk." 041b061a72
