Pro-Russia hacktivists are targeting and compromising small-scale operational technology (OT) systems in North American and European critical infrastructure sectors – including water and wastewater systems (WWS), dams, energy, and food and agriculture – according to a joint fact sheet released today by leading Federal cyber agencies.

The Cybersecurity and Infrastructure Security Agency (CISA) and FBI issued a joint cybersecurity advisory on Oct. 22 to warn operators of state, local, territorial, and tribal (SLTT) government networks that they may be targeted by Russian state-sponsored advanced persistent threat (APT) actors.
