Top 5 Most Useful Linux Tools For Programmers

Linux is a free and open-source software operating systems built around the Linux kernel. It typically packaged in a form known as a Linux distribution for both desktop and server use. It is a great development environment for programmers and developers. However, without the development tools, that would be impossible. Fortunately, plenty of Linux tools are available. Here are the top 5 most useful Linux tools for programmers.

5 Most Useful Linux tools for Programmers

1. VIM

VIM is a free and open source software written by Bram Moolenaar in 1991. It is designed for use both from a command-line interface and as a standalone application in a graphical user interface. It comes standard with almost every Linux distribution and is also known as "the programmer's editor". VIM is great for coding and can also be used for editing things like configuration files and XML documents.

Vim has been developed to be a cross-platform that supports many other platforms. In 2006, it was voted as the most popular editor amongst Linux Journal readers. In 2015, Stack Overflow developer survey found it to be the third most popular text editor while in 2016, the Stack Overflow developer survey found it to be the fourth most popular development environment.

2. Zsh

Zsh is written in C and initially released in 1990. It is a Unix shell that can be used as an interactive login shell and as a powerful command interpreter for shell scripting. Zsh is an extended version of Bourne shell (BASH) with a large number of improvements, including some features of Bash, ksh, and tcsh. Zsh gives a user-friendly experience on the command line. It also gives better auto-completion, Vim key bindings, and smart guesses when you write a command wrong.

Its features include (but not limited to):

Programmable command-line completion,
Sharing of command history among all running shells
Extended file globbing
Improved variable/array handling
Editing of multi-line commands in a single buffer
Spelling correction
Various compatibility modes,
Themeable prompts, and
Loadable modules.

3. Byobu

It was initially released in 2009 written in Sh and Python. Byobu can be used to provide on-screen notification or status and tabbed multi-window management. Thus, it is intended to improve terminal sessions when users connect to remote servers with an operating system Linux and Unix-like. It is is an enhancement for the GNU Screen terminal multiplexer or tmux used with the GNU/Linux computer operating system.

4. GIT

Git was initially released on April 7, 2005. It is a version control system to track changes in computer files and to coordinate work on those files among multiple people. It is primarily used for source code management in software development and can be used to keep track of changes in any set of files available in the English language. It is aimed at speed, data integrity, and support for distributed, non-linear workflows. It is free and open source software distributed under the terms of the GNU General Public License version 2.

Moreover, Linus Torvalds was the creator of GIT for the development of the Linux kernel. On the other hand, its current maintainer since then is Junio Hamano. Thus, every Git directory on every computer is a full-fledged repository with complete history and full version tracking abilities, independent of network access or a central server.

5. Docker

Written by Solomon Hykes in 2013, it is a computer program that performs operating-system-level virtualization, the containerization, which is developed by Docker, Inc. Primarily, Docker was developed for Linux to use as the resource isolation features of the Linux kernel. It is a tool that can package an application and its dependencies in a virtual container that can run on any Linux server. This helps enable the flexibility and portability on where the application can run, whether on premises, public cloud, private cloud, bare metal, etc. Moreover, it accesses the Linux kernel's virtualization features either directly using the libcontainer library.

How it works?
* Kali Linux with XFCE Desktop Environment in Windows Subsystem for Linux (WSL)
* VcXsrv X Server for Windows is doing the hard GUI lifting
* XFCE is started natively in WSL and displayed by VcXsrv

Install Voodoo-Kali:
1, Enable WSL and install Kali Linux from the Microsoft Store. Read Install Kali Linux desktop on Windows 10 from Microsoft Store

2, To start Kali Linux in Windows 10, open Command Prompt and enter the command: kali

3, Enter this commands:
  apt install wget -y
  wget https://raw.githubusercontent.com/Re4son/WSL-Kali-X/master/install-WSL-Kali-X
  bash ./install-WSL-Kali-X

4, Download and install VcXsrv Windows X Server from SourceForge

5, Start VcXsrv, accept change in firewall rules, exit VcXsrv

Run Voodoo-Kali:
Start kali in Windows as normal user (that's default), and launch Voodoo-Kali:
* as normal user: ./start-xfce
* as root: sudo /root/xtart-xfce

Run Kali Desktop in an RDP session:
In Kali Linux WSL, type: sudo /etc/init.d/xrdp start
In Windows 10, open Run and enter mstsc.exe and connect to "127.0.0.1:3390"

Status: Voodoo-Kali is in its infancy and it is far from being elegant. I'm working on it though and step by step I'll push out improvements. Below a snippet of the To-Do list:
* Clean up and comment the scripts
* Make for a cleaner exit
* Better error handling and dependency checking (get rid of sleep, etc.)
* Improve stability of Java programs
* Improve the looks??
* …

Any help is truly appreciated, in any shape or form – from tips to pull requests.

New Malware Used By SolarWinds Attackers Went Undetected For Years

The threat actor behind the supply chain compromise of SolarWinds has continued to expand its malware arsenal with new tools and techniques that were deployed in attacks as early as 2019, once indicative of the elusive nature of the campaigns and the adversary's ability to maintain persistent access for years.

According to cybersecurity firm CrowdStrike, which detailed the novel tactics adopted by the Nobelium hacking group last week, two sophisticated malware families were placed on victim systems — a Linux variant of GoldMax and a new implant dubbed TrailBlazer — long before the scale of the attacks came to light.

Nobelium, the Microsoft-assigned moniker for the SolarWinds intrusion in December 2020, is also tracked by the wider cybersecurity community under the names UNC2452 (FireEye), SolarStorm (Unit 42), StellarParticle (CrowdStrike), Dark Halo (Volexity), and Iron Ritual (Secureworks).

The malicious activities have since been attributed to a Russian state-sponsored actor called APT29 (also known as The Dukes and Cozy Bear), a cyber espionage operation associated with the country's Foreign Intelligence Service that's known to be active since at least 2008.

GoldMax (aka SUNSHUTTLE), which was discovered by Microsoft and FireEye (now Mandiant) in March 2021, is a Golang-based malware that acts as a command-and-control backdoor, establishing a secure connection with a remote server to execute arbitrary commands on the compromised machine.

Mandiant also pointed out that Dark Halo actors had used the malware in attacks going back to at least August 2020, or four months before SolarWinds discovered its Orion updates had been tampered with malware designed to drop post-compromise implants against thousands of its customers.

In September 2021, Kaspersky revealed details of a second variant of the GoldMax backdoor called Tomiris that was deployed against several government organizations in an unnamed CIS member state in December 2020 and January 2021.

The latest iteration is a previously undocumented but functionally identical Linux implementation of the second-stage malware that was installed in victim environments in mid-2019, predating all other identified samples built for the Windows platform to date.

Also delivered around the same timeframe was TrailBlazer, a modular backdoor that offers attackers a path to cyber espionage, while sharing commonalities with GoldMax in the way it masquerades its command-and-control (C2) traffic as legitimate Google Notifications HTTP requests.

Other uncommon channels used by the actor to facilitate the attacks include —

Credential hopping for obscuring lateral movement
Office 365 (O365) Service Principal and Application hijacking, impersonation, and manipulation, and
Theft of browser cookies for bypassing multi-factor authentication

Additionally, the operators carried out multiple instances of domain credential theft months apart, each time leveraging a different technique, one among them being the use of Mimikatz password stealer in-memory, from an already compromised host to ensure access for extended periods of time.

"The StellarParticle campaign, associated with the Cozy Bear adversary group, demonstrates this threat actor's extensive knowledge of Windows and Linux operating systems, Microsoft Azure, O365, and Active Directory, and their patience and covert skill set to stay undetected for months — and in some cases, years," the researchers said.
