During the last few weeks, according to a Washington Post report, the US military has carried out an operation to temporarily disrupt what has been described as the largest bot network in the world, which is used for delivering ransomware that official sources claim is the one of the main threats to the presidential election in November.
The campaign of the US Cyber Command is against the Trickbot network, an "army" of at least a million hijacked computers run by Russian-speaking criminals. It is not expected to break up the network permanently, said US officials who spoke on condition of anonymity because of the matter. But this is one way to distract them for at least some time before they restore their capabilities.
The effort is part of what General Paul Nakasone, head of the Cyber Command, calls "persistent engagement", or imposing cumulative costs on the adversary. Official sources said that this is a main characteristic of the activity of the Cyber Command to help defend the election against foreign threats.
“Right now, my top priority is for a safe, secure, and legitimate 2020 election,” said Nakasone in August in a set of written responses to questions by the Washington Post. “The Department of Defense, and Cyber Command specifically, are supporting a broader ‘whole-of-government’ approach to secure our elections.”
