Spanish police said on July 20 that they had arrested three people accused of taking part in cyberattacks by a pro-Russian group targeting public institutions and strategic sectors in Spain and other NATO countries. The attacks targeted countries that have supported Ukraine in its struggle against the Russian invasion. The three were arrested for "computer-related offenses with terrorist intent" over a string of distributed denial-of-service (DDoS) attacks, which make websites or network resources unavailable by flooding them with malicious traffic. The attacks were "organized by the Russian-linked hacker group called NoName057(16)," it said, without giving further details.
