I believe some of my zoom meetings have been hacked

Hi, I recently recorded an instance of possible third party hacking of a Zoom meeting of mine due to recorded voices of third parties making rude comments during a conference call. I have an audio snippets of one the incidents. The third party voice heard in the recording is shouting an expletive (his voice is slightly muffled but he can be heard shouting "WTF?!").  I'm not sure how my meeting was hacked as there were only 2 participants shown in the entire duration of the meeting. I can send the file to an admin via email. Please help me and thank you.
