The Department of Justice (DOJ) has charged a Ukrainian woman with helping to carry out dozens of cyberattacks on critical U.S. infrastructure, working with Russian-backed hackers, according to newly unsealed indictments.

The State Department’s Rewards for Justice program is also offering up to $10 million for information leading to others tied to one of the pro-Russia hacking groups she was allegedly affiliated with.

Victoria Eduardovna Dubranova, 33, was arraigned Tuesday on a second federal indictment after being extradited to the U.S. earlier this year.

Dubranova, also known as Vika, Tory and SovaSonya, pleaded not guilty to charges related to her alleged work with two Russian-backed operations, CyberArmyofRussia_Reborn (CARR) and NoName057(16).

Prosecutors say both groups receive backing from Russian government bodies to push Russian geopolitical interests.

According to the DOJ, CARR was founded and funded by Russia’s military intelligence agency, the GRU, and operated a popular Telegram channel with more than 75,000 followers.

Officials allege the group’s attacks caused real-world harm, including damage to public water systems that spilled hundreds of thousands of gallons of drinking water.

They also cited a November 2024 breach at a Los Angeles meat processing plant that spoiled thousands of pounds of product and released ammonia.

“Today’s actions demonstrate the Department’s commitment to disrupting malicious Russian cyber activity — whether conducted directly by state actors or their criminal proxies — aimed at furthering Russia’s geopolitical interests,” said Assistant Attorney General for National Security John A. Eisenberg. 

“We remain steadfast in defending essential services, including food and water systems Americans rely on each day, and holding accountable those who seek to undermine them.”

NoName057(16) is described as a Russia-linked hacktivist group responsible for more than 1,500 attacks between March 2022 and June 2025.

Its targets included government agencies, telecommunications firms, the military, financial institutions and transportation authorities across Ukraine, Estonia, Finland, Lithuania, Norway, Poland and Sweden.

The group also claimed responsibility for cyberattacks on Dutch infrastructure ahead of and during the 2025 NATO Summit in The Hague.

These groups “are actively engaging in opportunistic, low-sophistication malicious cyber activity to gain notoriety and create mayhem,” said Chris Butera, CISA’s acting deputy executive assistant director for cybersecurity.

Dubranova faces up to five years in the NoName case and as many as 27 years in the CARR matter. Trials are set for February and April 2026.

Rewards for Justice announced its $10 million reward with a pointed message aimed at other NoName participants: “They call themselves ‘NoName.’ But maybe YOU can name some names,” it said.
