So... NO... most NJ residents cannot buy suppressors.
There are however many of you that I know own vacation homes and properties out of state, like in PA. You may actually be able to own suppressors.
Was having this discussion with my local purveyor of fine arms and evil items, @FreedomSportsLLC.
If you own a place outside of NJ, where suppressors are legal, you are likely able to purchase one with proper documentation.
The big caveat is though, you can only keep them and shoot them in PA. Obviously illegal in NJ.

"An ongoing Chinese hacking campaign known as Volt Typhoon has successfully gained access to numerous American companies in telecommunications, energy, water and other critical sectors, with 23 pipeline operators targeted, FBI Director Christopher Wray said"
"China is developing the "ability to physically wreak havoc on our critical infrastructure at a time of its choosing. Its plan is to land low blows against civilian infrastructure to try to induce panic."
I think this is actually just an elaborate Chinese marketing campaign to sell more radios and cheap survival gear.
