Ukrainian hacktivist operation IT Army has taken credit for a significant cyberattack against Russian state-owned railway firm RZD, which resulted in the disruption of its website and mobile app for at least six hours, according to The Record, a news site by cybersecurity firm Recorded Future.
Operations have already been restored by RZD although certain online services remain unavailable amid ongoing attacks but IT Army said in a message on its Telegram channel that it did not intend to permanently dismantle the Russian railway's website.
"It requires significant effort to prepare an attack on such a target. Even if the website is down only for an hour, it would still have a significant impact on the economy of the aggressor country," said IT Army.
Such an attack comes after the RZD had its website and mobile app taken offline by distributed denial-of-service attacks in the early days of the war between Russia and Ukraine.
Russia-based threat actors have been blamed by Bermuda Premier David Burt for being behind significant internet outages across the British overseas territory and another government in the Caribbean, reports The Record, a news site by cybersecurity firm Recorded Future.
