Team OneFist is a pro-Ukrainian hacktivist group involved in cyber operations against Russian targets during the Russia-Ukraine war. The group has been publicly associated with attacks on Russian infrastructure and surveillance systems, and has been linked to intelligence-support activity for Ukrainian military efforts. Reported operations include compromising Russian surveillance cameras to obtain information on troop and equipment movements, as well as destructive activity against exposed OT-adjacent and industrial networking devices. Team OneFist has also claimed disruption of fuel-related monitoring equipment in Russia, including an automatic tank gauge, and has been tied to the wiping of an exposed industrial router in Moscow. The group’s observed tradecraft indicates a focus on opportunistic targeting of Internet-exposed infrastructure, especially embedded and industrial devices, with destructive or disruptive outcomes rather than covert persistence. Based on the available reporting, Team OneFist is best characterized as a hacktivist actor aligned with Ukrainian wartime objectives, targeting Russian infrastructure for disruption and intelligence value.
