Pro-Russian hackers were behind a “large-scale” cyberattack on Bulgarian government websites on Saturday, according to Bulgaria’s Prosecutor-General Ivan Geshev.
Pro-Russian hacker collective Killnet disrupted the websites of several US airports via DDoS attacks, and critical infrastructure will likely continue to face escalating cyber threats.
Killnet calls on other groups to launch similar attacks against US civilian infrastructure, including marine terminals and logistics facilities, weather monitoring centers, and healthcare systems.
