The extraction tools or the ISOs themselves often contain keyloggers, ransomware, or remote access trojans (RATs). Your main computer could be compromised before you even boot the operating system. 2. Backdoored Operating Systems
: Third-party sites offering compressed versions often inject keyloggers, backdoors, or ransomware into the image. Since Kali is used for sensitive security work, using a compromised OS is self-defeating.
While the official Kali Linux ISO images are typically 4 GB+, a highly compressed image can sometimes be reduced to under 1-2 GB, while still expanding into a full, functional operating system. Key Characteristics
The official Kali Linux ISO is already highly compressed using the XZ algorithm. When a user downloads the official ISO, they are downloading a compressed image. When the system is booted, it decompresses data on-the-fly into RAM (Random Access Memory). This is an efficient method for running a full penetration testing suite on hardware with limited storage, as the system does not need to be installed on the hard drive. kali linux highly compressed
