MADRID Spanish National Police arrested a man suspected of being an active member of the pro-Russian hacktivist groups CyberArmy of Russia Reborn, also known as CARR, and Z-Pentest. According to the Spanish police announcement, the arrested individual, who lived in Palencia, provided logistical and operational support to a Ukrainian hacker who operated for CARR. Investigators later determined he had also worked with Z-Pentest, an offshoot of Cyber Army of Russia Reborn, and may have carried out attacks by NoName057(16). Acting on a tip from the U.S. Federal Bureau of Investigation, Spanish National Police took the suspect into custody from his home in the city of Palencia for allegedly partnering with Cyber Army of Russia Reborn. The suspect was arrested on suspicion of membership in and collaboration with a terrorist organization, glorification of terrorism and computer-related offenses, Spain's Interior Ministry said. In March 2026, the authorities raided the suspect's home in Palencia and seized computers and cryptocurrency storage devices, which will be used in the ongoing investigations. According to investigators, the suspect participated in actions attributed to the pro-Russian hacktivist group NoName057(16).
