Minecraft’s resource pack system is strictly client-side visual and audio content. It runs in a sandbox that does not allow actual scripts, executables, or memory manipulation. If a file claims to be an "aimbot" but ends in .zip or .mcpack , it is mathematically impossible for it to move your aim for you.
Legitimate texture pack platforms (CurseForge, Modrinth) do not host aimbot packs. Suspicious files are often hosted on mediafire, discord CDNs, or anonymous file dump sites.
