Spain arrests alleged pro-Russia hacktivist linked to CARR, Z-Pentest, and NoName057(16) after FBI tip

Spanish police arrested a man in Palencia who they say supported pro-Russia hacktivist groups tied to attacks on critical infrastructure in Western countries. Police said the suspect had close ties to CyberArmy of Russia Reborn (CARR) and Z-Pentest, may have carried out actions for NoName057(16), helped a Ukrainian CARR member flee toward Russia via Poland and Belarus, and held seized computer equipment and cryptocurrency allegedly linked to cybercrime proceeds.
Why it matters: This signals continued international disruption of Russian-aligned hacktivist networks that have targeted public and private critical services, often with denial-of-service attacks that can still knock essential systems offline. Organizations in sectors such as energy, water, agriculture, and government should keep DDoS defenses and monitoring tuned for these actors.
