Tools of Kali Linux Do you want to learn more about cybersecurity tools? Have you ever opened Kali Linux and not know where to begin? Here we have created a small list of tools that are part Kali Linux. Some of our career field experts have given us their short list of tools that they would recommend for individual interested in learning more about cybersecurity. Looking at the menus in Kali Linux can be overwhelming. Hopefully this short list can help you navigate the introduction to Kali Linux Operating System (OS). You don’t need to have Kali Linux to try any of these tools, but it does make it much easier. John the Ripper John the Ripper is the name of the password cracker tool that is developed by Openwall. As the name, it is used to crack password hashes by using its most popular inbuilt program, rules and codes that are also an individual password cracker itself in a single package. It automatically detects types of password hashes; you can also customize this tool according to your wish. It can be used to crack password-protected compressed files like Zip, Rar, Doc, pdf etc. Nmap Nmap is short for Network Mapper. It is an open-source Linux command-line tool that is used to scan IP addresses and ports in a network and to detect installed applications. Nmap allows network admins to find which devices are running on their network, discover open ports and services, and detect vulnerabilities. Gordon Lyon (pseudonym Fyodor) wrote Nmap as a tool to help map an entire network easily and to find its open ports and services. Nmap Scripting Engine (NSE) The Nmap Scripting Engine (NSE) is one of Nmap's most powerful and flexible features. It allows users to write (and share) simple scripts (using the Lua programming language) to automate a wide variety of networking tasks. Those scripts are executed in parallel with the speed and efficiency you expect from Nmap. Users can rely on the growing and diverse set of scripts distributed with Nmap, or write their own to meet custom needs. Wireshark Wireshark is the world’s foremost and widely-used network protocol analyzer. It lets you see what’s happening on your network at a microscopic level and is the de facto (and often de jure) standard across many commercial and non-profit enterprises, government agencies, and educational institutions. Wireshark development thrives thanks to the volunteer contributions of networking experts around the globe and is the continuation of a project started by Gerald Combs in 1998. Metasploit Metasploit is one of the best penetration testing frameworks that help a business find out and shore up vulnerabilities in their systems before exploitation by hackers. To put it simply, Metasploit allows hacking with permission. Metasploit was conceived and developed by H D Moore in October 2003 as a Perl-based portable network tool for the creation and development of exploits. By 2007, the framework was entirely rewritten in Ruby. In 2009, Rapid7 acquired the Metasploit project, and the framework gained popularity as an emerging information security tool to test the vulnerability of computer systems. Metasploit 4.0 was released in August 2011 and includes tools that discover software vulnerabilities besides exploits for known bugs. Armitage Armitage is a fantastic Java-based GUI front-end for the Metasploit Framework developed by Raphael Mudge. Its goal is to help security professionals better understand hacking and help them realize the power and potential of Metasploit. OpenVAS – Open Vulnerability Assessment Scanner OpenVAS is a full-featured vulnerability scanner. Its capabilities include unauthenticated and authenticated testing, various high-level and low-level internet and industrial protocols, performance tuning for large-scale scans and a powerful internal programming language to implement any type of vulnerability test. The scanner obtains the tests for detecting vulnerabilities from a feed that has a long history and daily updates. OpenVAS has been developed and driven forward by the company Greenbone Networks since 2006. As part of the commercial vulnerability management product family Greenbone Enterprise Appliance, the scanner forms the Greenbone Vulnerability Management together with other Open-Source modules. MASSCAN MASSCAN is aTCP port scanner which transmits SYN packets asynchronously and produces results similar to nmap, the most famous port scanner. Internally, it operates more like scanrand, unicornscan, and ZMap, using asynchronous transmission. It’s a flexible utility that allows arbitrary address and port ranges. Harvester Harvester is a modern Hyperconverged infrastructure (HCI) solution built for bare metal servers using enterprise-grade open-source technologies including Kubernetes, Kubevirt and Longhorn. Designed for users looking for a cloud-native HCI solution, Harvester is a flexible and affordable offering capable of putting VM workloads on the edge, close to your IoT, and integrated into your cloud infrastructure.

Safety tip of the day
How safe are you with your passwords with your internet browser?
Do you practice good password security?
Do you use your web browser to save passwords from websites?
To answers these questions, I’ll share with an experience I had. I won’t share the brand name of this web browser just to stay out of trouble. A friend of mine bought a new computer and asked me to help him with the initial setup. We went through all of the normal configuration of a new laptop and transferred his information from the old laptop to the new one. After the setup he went through the new laptop to see if anything was missing from the old laptop. Turns out that he didn’t document some login and password information from some websites he uses. I did a little digging and found out that the web browser he was using would ask to save this information from websites. I found this in the settings of the web browser and plain as day, an unsecure folder with an entire list of websites he visited with the user I.D. and password associated with it. I’m no Cyber security expert, If I can locate this, then the criminals won’t have any problem at all. In this folder I found 41 unique websites with all the credentials needed to log in to that website including the ones he was missing.
The fix.
Don’t save any login information in your web browser. I would recommend using a password manager as there are a number of good ones out there and a lot of them will offer a basic account for free. Adding a password manager is adding an extra layer of protection from getting your information stolen, putting your login information behind password protection.
We’ve written on a number of occasions already this month that Google was launching a test of new technology in Google Chrome called FLoC, which stands for Federated Learning of Cohorts. It’s ostensibly meant to let Chrome improve the anonymity of users — which is something Google vowed to do a few weeks ago, via a movie to stop allowing advertisers to track users online with third-party cookies. However, Chrome will do this via FLoC while also still collecting some users’ browsing data for advertising purposes. What struck many people as particularly frustrating is that even though Google said it would test this as part of a limited pilot run before rolling it out fully, the search giant didn’t offer a straightforward way to opt out of the testing.

If your employees don’t know how #cyberattacks occur, how will they be able to spot them? Here’s a great article that helps break down what happens during an attack, along with some of the most common threats to be aware of
A guide to the different methods cybercriminals use to harm computers and steal data
Cyberattacks are performed by malicious actors with various intentions, though the tools and methods they use are often the same.
- A cyberattack is an assault on any computer or network, almost always launched from another computer or network.
- There are a lot of ways malicious actors can launch a cyberattack, including malware, zero-day exploits, and denial-of-service attacks.
- Here’s a brief overview of cyberattacks and what you need to know about their risk.

Putting a PIN on your Charger or Challenger limits anyone else to idle speed.
Autoblog points out the Security Mode update that the carmaker will soon make available to owners of 2015 or newer Charger and Challenger models equipped with large HEMI V-8 engines. It’s adding two-factor authentication, only instead of sending a push notification to your phone or generating a code, it’s a simple four-digit PIN. Combining something you know with something you have (your car key) is required to make the car unlock its full potential. With the security feature turned on, unless you input the code the engine won’t rev beyond idle speed (675 RPM) where it only has about 2.8 HP and 22 pound-feet of torque.
