Hello Friends, Today I’m going to explain the Hashcat password Cracking Tool, As I learn from my cybersecurity classes and reading some blogs doing practices and the help of infosec boy’s able to explain it, so obviously the credits goes to Armour Infosec<\/a><\/strong>. Password cracking and user account exploitation is one of the most issues in cybersecurity field. Password Cracking tools, like Hashcat and John the Ripper, Provide the potential attackers to check billions of passwords per second against Victim’s password hashes. these tools have proved to be effective in cracking passwords, recent research shows that combining deep learning techniques with these tools can produce significantly better results. Specifically, using Generative Adversarial Networks (GANs), which comprises of two neural networks, to generate high-quality password guesses can improve the existing tools to match 51%-73% more passwords than just the tools alone. This significant improvement demonstrates that this new approach using deep learning can generate numerous new pass-words that were once beyond the reach of other tools.On one hand, this is an impressive result driven by researchers of deep learning and cybersecurity, and on the other, a strong warning to the community of the increasing dangers of weak password authentication.<\/p>\n This blog is a reference guide for cracking, tool usage and supportive.tools that assist pentesters in password recovery (cracking). this will not be covering the installation of these tools but will include references to their proper installation, and if all else fails, Google. Updates and additions to this blog are planned yearly as advancements in cracking evolve.<\/p>\n \u201cPassword recovery is a battle against math, time, cost, and human behavior, and much like any battle, the tactics are constantly\u00a0 evolving.\u201d<\/p>\n In order to follow many of the techniques in this manual, you will need to install the following software on your UNIX host.
