The brothers’ actions date again to early 2023. The 2 used a distributed cloud assault software (DCAT) known as “Skynet Botnet” so as to “conduct damaging DDoS assaults and publicly declare credit score for them,” in accordance with a DoJ assertion. Ahmed posted a message on Nameless Sudan’s Telegram channel, “The USA have to be ready, will probably be a really massive assault, like what we did in Israel, we’ll do in america ‘quickly.’”

One of many indictments listed 145 “overt acts” on organizations and entities within the US, the European Union, Israel, Sudan and the United Arab Emirates (UAE).
