Third, and most critically, the security risks are severe. No reputable source vouches for the integrity of these releases. The anonymous group or individual who assembles the ISO has full control over its contents. Beyond the activation crack, they can embed persistent backdoors, keyloggers, cryptominers, or rootkits into the bootloader, recovery environment, or default user profile.
