Volunteer Hackers in Ukraine Take Down Sites for Stock Exchange, Bank

Websites for the Russian Foreign Ministry as well as the country’s largest stock exchange and a key state-owned bank were offline, as loosely organized groups of volunteer hackers pledged to retaliate against the Kremlin for its invasion of Ukraine. An “IT army” created by the Ukrainian government urged more than 200,000 followers on its Telegram channel to attempt to take down the website of the Moscow Exchange.
