A new botnet called 'RapperBot' is being used in attacks since mid-June 2022, focusing on brute-forcing its way into Linux SSH servers to establish a foothold on the device. Over the past 1.5 months since its discovery, the new botnet used over 3,500 unique IPs worldwide to scan and attempt brute-forcing Linux SSH servers.
A never-before-seen Linux malware has been dubbed a "Swiss Army Knife" for its modular architecture and its capability to install rootkits. This previously undetected Linux threat, called Lightning Framework by Intezer, is equipped with a plethora of features, making it one of the most intricate frameworks developed for targeting Linux systems.
A new and previously undetected malware dubbed 'Lightning Framework' targets Linux systems and can be used to backdoor infected devices using SSH and deploy multiple types of rootkits. Described as a "Swiss Army Knife" in a report published today by Intezer, Lightning Framework is a modular malware that also comes with support for plugins.
Kaspersky security researchers have disclosed details of a brand-new ransomware family written in Rust, making it the third strain after BlackCat and Hive to use the programming language. Luna, as it's called, is "Fairly simple" and can run on Windows, Linux, and ESXi systems, with the malware banking on a combination of Curve25519 and AES for encryption.

SSH is a tool I use every single day to log into remote Linux servers and take care of my admin tasks. Here are my five most straightforward tips for securing SSH on your Linux machines.
Linode + Kali Linux: Added security for cloud instancesKali Linux, the popular open source Linux distribution specialized for penetration testing, ethical hacking and security auditing, can now be used by Linode customers. The enemy of vulnerability management? Unrealistic expectationsOrganizations vary by size, industry, level of maturity, but one thing that they all have in common is needing to know how to quickly remediate security vulnerabilities.
Kali Linux, the popular open source Linux distribution specialized for penetration testing, ethical hacking and security auditing, can now be used by Linode customers. A bare-install verson in the form of an official Kali distribution that can be deployed on any Linode compute instance and used via a command line interface.
A sneaky malware for Linux is backdooring devices to steal data and can affect all the processes running on a particular machine, researchers have found. Orbit can either achieve persistence on a machine or be installed as volatile implant, Intezer's Nicole Fishbein explained in a blog post on Orbit published this week.
A newly discovered Linux malware is being used to stealthily steal information from backdoored Linux systems and infect all running processes on the machine. Dubbed OrBit by Intezer Labs security researchers who first spotted it, this malware hijacks shared libraries to intercept function calls by modifying the LD PRELOAD environment variable on compromised devices.
