Need a bit of advice please.

I sold a watch to a US buyer through ebay for £2500 last Saturday. He paid promptly and sale amount has already been transferred into my bank account by Ebay.

I shipped the watch on Tuesday by UPS and used Secursus insurance for full amount.

Today I received an email from Ebay basically saying that the buyers account had been hacked, attached screenshot of the email.

Where do stand in this situation? I already have the funds in my account, can Ebay take it back? Will ebay bill me for the sale amount? None of this is my fault and I've gone through all the correct procedures?
