Pentoo is also available as an overlay [7] for an existing Gentoo installation. It features packet injection patched Wi-Fi drivers, GPGPU cracking software, and many tools for penetration testing and security assessment.
Breaking a symmetric 256-bit key by brute-force requires 2 128 times more computational power than a 128-bit key. One of the fastest supercomputers in 2019 has a speed of 100 petaFLOPS which could theoretically check 100 trillion (10 14 ) AES keys per second (assuming 1000 operations per check), but would still require 3.67×10 55 years to ...
Kali Linux has a dedicated project set aside for compatibility and porting to specific Android devices, called Kali NetHunter. [14]It is the first open source Android penetration testing platform for Nexus devices, created as a joint effort between the Kali community member "BinkyBear" and Offensive Security.
In February 2024, a malicious backdoor was introduced to the Linux build of the xz utility within the liblzma library in versions 5.6.0 and 5.6.1 by an account using the name "Jia Tan". [ b ] [ 4 ] The backdoor gives an attacker who possesses a specific Ed448 private key remote code execution through OpenSSH on the affected Linux system.
BackBox is a penetration test and security assessment oriented Ubuntu-based Linux distribution providing a network and informatic systems analysis toolkit. [3] It includes a complete set of tools required for ethical hacking and security testing.
The rise of 64-bit x86 processors brought with it a change to the subroutine calling convention that required the first few arguments to a function to be passed in registers instead of on the stack. This meant that an attacker could no longer set up a library function call with desired arguments just by manipulating the call stack via a buffer ...
Like Unix systems, Linux implements a multi-user environment where users are granted specific privileges and there is some form of access control implemented. To gain control over a Linux system or to cause any serious consequences to the system itself, the malware would have to gain root access to the system.
Linux kernel (<4.8.3) Dirty COW ( Dirty copy-on-write ) is a computer security vulnerability of the Linux kernel that affected all Linux-based operating systems, including Android devices, that used older versions of the Linux kernel created before 2018.
