A nulled script refers to a pirated or cracked version of a software or script, often distributed through unofficial channels. These scripts are usually modified to bypass licensing restrictions, allowing users to access premium features without paying for them. However, this comes with significant risks, as nulled scripts can contain malware, backdoors, or other security vulnerabilities.

Malware & Backdoors:

Most nulled scripts contain hidden malicious code (backdoors) that can give hackers access to your server or steal user data.
