DCG 201 Online CTF — PlaidCTF 2021 — April 15th-18th

Welcome to the PlaidCTF 2021!

For over two years we have been planing running our own Wargames and CTF to help people develop their hacking skills. While progress is still being made (we plan to launch our own in Summer 2021), DCG 201 will also occasionally enter into various online CTF Tournaments to test our skills and to get a sample on how one is set up so we have a blueprint in creating our own.

On Friday, April 16h, 5:00 PM EST to April 18st, 5:00 PM EST, we invite all DCG 201 Members, Attendees and Fans to help us hack the PlaidCTF 2021!

Recommended OS Platforms:

Kali Linux is a Debian-derived Linux distribution designed for digital forensics and penetration testing that incorporates more than 300 penetration testing and security auditing pre-installed. Kali Linux is distributed in 32-bit and 64-bit images for use on hosts based on the x86 instruction set and as an image for the ARM architecture for use on the Asus Chromebook Flip C100P, BeagleBone Black, HP Chromebook, CubieBoard 2, CuBox, CuBox-i, Raspberry Pi, EfikaMX, Odroid U2, Odroid XU, Odroid XU3, Samsung Chromebook, Utilite Pro, Galaxy Note 10.1, and SS808.

Kali Linux is also available on Windows 10, on top of Windows Subsystem for Linux (WSL). The official Kali distribution for Windows can be downloaded from the Microsoft Store:

Parrot OS is a GNU/Linux distribution based on Debian’s testing branch (Bullseye) and a Linux 5.4 kernel with a focus on security, privacy, and development. It provides a suite of penetration testing tools to be used for attack mitigation, security research, forensics, and vulnerability assessment. The OS is certified to run on devices which have a minimum of 256MB of RAM and it is suitable for both 32-bit (i386) and 64-bit (amd64) processor architectures. In addition, the project is available for ARMv7 (armhf) architectures available for Raspberry Pi devices. The desktop environments are MATE and KDE.

You have two options for Fedora. First is Fedora Security Lab which provides a safe test environment to work on security auditing, forensics, system rescue and teaching security testing methodologies in universities and other organizations. It comes with the clean and fast Xfce Desktop Environment and a customized menu that provides all the instruments needed to follow a proper test path for security testing or to rescue a broken system.

Network Security Toolkit (NST) is a bootable live CD based on the Fedora distribution. The toolkit was designed to provide easy access to best-of-breed open source network security applications and should run on most x86 platforms. The main intent of developing this toolkit was to provide the network security administrator with a comprehensive set of open source network security tools.

Pentoo, based on Gentoo Linux, is a Live CD and Live USB designed for penetration testing and security assessment. Pentoo is provided both as 32 and 64 bit installable live CD. Pentoo is also available as an overlay for an existing Gentoo installation. It features packet injection patched wifi drivers, GPGPU cracking software, and lots of tools for penetration testing and security assessment. The Pentoo kernel includes grsecurity and PAX hardening and extra patches — with binaries compiled from a hardened toolchain with the latest nightly versions of some tools available. Tools are installed with versioned ebuilds and open-ended ebuilds, making it possible to pull in the latest subversions and still have installs tracked by package management.

BlackArch is an open-source distro and penetration testing distribution based on Arch Linux that provides a large amount of cyber security tools, created specially for penetration testers and security researchers. The repository contains more than 2400 tools that can be installed individually or in groups. BlackArch Linux is compatible with existing Arch Linux installs.

PentestBox is an Open Source, Pre-Configured Portable Penetration Testing Environment for the Windows Operating System. It provides all the security tools as a software package and lets you run them natively on Windows. This effectively eliminates the requirement of virtual machines or dualboot environments on windows. All the dependencies required by tools are inside PentestBox, so you can even run PentestBox on freshly installed windows without any hassle. PentestBox is entirely portable, so now you can carry your own Penetration Testing Environment on a USB stick. It supports both 32-bit and 64-bit systems.

Apple iMac machines run a POSIX compliant UNIX variant, and the hardware is essentially the same as what you would find in a high-end PC. This means that most hacking tools run on the Mac operating system. A properly set up Apple machine can do quite a bit of heavy lifting.

SecBSD is a security pen-testing system for BSD users. SecBSD is an UNIX-like operating system focused on computer security OpenBSD-based. A BSD environment for security researchers, pen-testers, bug hunters & cybersecurity experts.
