Czech military intelligence joins international operation against Russian hackers

The Military Intelligence of the Czech Republic took part in a major international operation in March targeting hackers linked to Russia’s military intelligence, the GRU. The operation, led by the Federal Bureau of Investigation, focused on the cyber-espionage group APT28. Czech officers intervened by securing compromised devices and adjusting parts of the infrastructure exploited by hackers to collect sensitive military and state data. According to officials, such networks had been used against targets in Czechia and allied countries in NATO and the EU. The agency stressed that effective cyber defence requires disrupting entire networks at once, as advanced groups can quickly adapt. It also urged the public to improve basic cyber hygiene, warning that unsecured personal devices can serve as entry points for attacks on critical infrastructure.
