If the usa does I don't understand why you expect we'd know about it. Also the us totally does and we do know about it - the nsa buys zero days - it's not exactly a secret lol
Right- and they probably do, and they don't know it was us just like cloudflare doesn't know what country it was. For all we know that cloudflare attack was the US. I don't know why China/Russia/Iran/nk would be able to carry out the cloudflare attack without cloudflare being able to pin who exactly did it while the US is supposed to be so incompetent that we would be immediately identified and called out?
