Spain arrests suspected hacker linked to Russian hacktivist campaign

Spanish authorities, coordinated with the FBI, arrested an alleged member of the pro‑Russian hacktivist group Cyber Army of Russia Reborn (aka Z‑Pentest) who is accused of facilitating attacks on critical infrastructure and aiding a linked hacker’s escape to Russia; investigators seized computers and cryptocurrency devices and froze a wallet tied to payments. The report places the arrest in the context of prior U.S. sanctions, DOJ indictments, and a joint advisory warning about pro‑Russian hacktivist threats, noting ongoing international law enforcement and reward efforts to disrupt the groups.
