One of the Killnet accounts on Twitter has published a tweet in which is stated that a lot of work still needs to be done. The tweet itself included the hashtag USA. Once the Killnet tweet is translated, it roughly translates to:
Lots of work to do.
But first we will end with the Italian mafia, which has been in power for many years and robs its people.

The tweet
