27.01.2022

In this video learn a simple method for detecting possible SQL injection attacks. The consequences of misconfigured SQL can be extremely severe such as: 1. Complete access to private data such as customer data. 2. The possibility to completely destroy important database records that are not backed up. It can be as simply as checking forms with a single or double quote payload to see if any errors are provided. Watch the video to see an example of this in practice along with analysis of the resultant error. 00:00 Intro 00:17 What is SQL? 02:58 Sending an SQL injection payload 04:11 Interpreting the http response 05:32 Analyzing the SQL query 06:57 Are error disclosures ok in a web app? 08:03 Enumeration of vulnerabilities 10:04 Summary

In this video we run the BlackArch Linux update command. If there are any downsides to this distro it's that we potentially have a lot of packages to updade, so the process can take a while and involve a number of errors. We'll deliberately run into these errors and solve them as they crop up. This way we'll mirror a typical install process for a Black Arch user. 00:00 intro 00:30 Running sudo pacman -Syu 00:44 Adding our user to the sudoers file 03:07 Adding our user to the wheel user group 03:43 Re-running sudo pacman -Syu 03:58 Replacing existing and conflicting packages including tesseract wall of text 05:28 Information from Black Arch on the update process 06:07 Importing PGP keys 06:47 Packages corrupted error message 08:28 sudo pacman-key refreshkeys 10:20 pygrun conflicting files error 11:28 Black Arch update complete.

Install BlackArch on Virtualbox Using .OVA Image

00:06:53
27.09.2021

We are going to be installing BlachArch on Virtualbox. BlackArch is a very cool linux distro geared around penetration testing. It is based on Arch linux unlike the most popular penetration testing Kali linux which is based on Debian. BlackArch is (depending on your opinion) has a slightly steeper learning curve than Kali, but it's great for those who prefer Arch linux and/or want a wider selection of pre-installed penetration testing tools. (We'll be using this BlachArch in later videos to solve some of the OWASP juice shop challenges). Perhaps we are already familiar with the process of installing a virtual machine via an ISO. An OVA image is even faster since it's essentially an image of an operating system that has already been installed. We'll use the OVA image in this tutorial. 1. Head to BlackArch official site and grab the OVA image (torrents recommended). 2. Run the OVA image through SHA1 hashing algorithm and compare to the checksum (SHA1sum). Although the image will still work without this step - if you plan on becoming a cyber security professional you should ABSOLUTELY NOT SKIP THIS STEP. 3. In Virtualbox go to file / import appliance. Choose 'Local File System', then open the file browser to select our OVA image. 4. Tweak appliance settings (if desired). The default settings will usually be fine however. 5. Choose Machine Base Folder (where we want our virtual machine drive to be located). 6. Choose Import, accept the joke software license agreement. Give it a few minutes, job done.
