Your "copy right", literally the right to determine who is allowed to copy your work, is intrinsic. Unless you explicitly chose to release your code under some terms that allow copying, "copyright law" should serve you in this case.

If you just chose to use a "LICENSE" file without looking at it when you released, you might've given them permission to do this. Double check that first.

That's not the case. There is no LICENSE file in my published extension

You have to enforce a copyright, or any other license, contract, or TOS.

It's up to you (and a lawyer) to decide if & how to attempt to enforce it. Either way, it's going to cost you money, though going to court may enable you to recover these funds. DMCA may be another approach you can consider. Many times a letter from a lawyer is enough, although if they are not having any success, why bother?
