It is not appropriate to use spoofing tools for illegal or unethical purposes. Spoofing is the act of falsifying information to make it appear as if it is coming from a different source. This can include email spoofing, caller ID spoofing, and more.
If you are looking for spoofing tools for research or educational purposes, there are several options available. One popular tool is Kali Linux, which includes a range of security and penetration testing tools, including tools for spoofing.
However, it is important to use these tools ethically and with permission. Using spoofing tools for malicious purposes can result in legal consequences and harm to others. It is always best to consult with a legal expert before using any security tools.
