Malware/adware/spyware/hacker Need help. MacBook Pro latest software and iPhone 12 Pro Max (iCloud) maybe

ssh-keygen-wrapper?

That's not the secure shell service (ssh). You can disable Full Disk Access for it. It is likely in everybody's Full Disk Access list.

If you have been a victim of identity theft, you should contact your local authorities that deal with that sort of thing. You should also consult a digital forensics expert to evaluate your Mac. Nobody can do that online.

Any use of the computer compromises any evidence of infiltration.

And, it's not likely your Mac or you iPhone where any information was exfiltrated. It is from any of the various online accounts you have established.

Someone found out, or guessed what your Apple ID and password is. Once they know that, they can log in to your account as you. From there, they can see and manipulate all of the same data you do. Emails, photos, messages, etc.

Change the password on your account. Change all of the two factor ID questions. Make sure to use nonsensical answers. Such as if the question is, "Where were you born?", and you use the factual answer, a person you know who could possibly be the person in your account could answer it. Instead, use a nonsense answer such as "Jupiter".

Uninstall Norton/Symantec. Third party apps that claim to protect, manage, boost performance, etc. are not needed and may cause problems.

There's nothing in your report to show any unwanted service is running.

That said, Norton is a complete waste of your time and money. The only thing this type of software is good for is putting money into the pockets of the people who make it. You should remove it.

Suggest the following and all from Apple.
