Understanding Landshark: A Linux Rootkit Used in Cyber Attacks

Landshark is a term used in the context of computer networking and security. It refers to a type of malware that targets Linux-based systems, specifically those running on the Linux kernel.

Landshark is a rootkit, which is a type of malware designed to gain unauthorized access to a computer system or network. Rootkits are typically used to gain control of a system or to hide other malicious software from detection by security software.

The Landshark rootkit was first discovered in 2014 and has been associated with various cyber attacks and campaigns since then. It is known to target Linux systems running on a variety of distributions, including Ubuntu, Debian, and CentOS.

Landshark works by injecting malicious code into the Linux kernel, which allows it to gain elevated privileges and hide its presence from security software. Once installed, Landshark can be used to steal sensitive information, such as login credentials and encryption keys, or to take control of the infected system.

To protect against Landshark and other types of malware, it is important to keep your operating system and software up to date with the latest security patches, use strong passwords and two-factor authentication, and use a reputable antivirus program to scan for and remove any suspicious files or activity.
