More than 600 websites belonging to the defence ministry in Kyiv and other institutions suffered attacks with the launch of thousands of exploits with attempts pointed to at least 20 distinct vulnerabilities. The campaign started mid-February and peaked on 23 February. The attacks sought to infiltrate targets ranging from border defence forces to the national bank and railway authority. They were designed to steal data and explore ways to shut down or disrupt vital defence and civilian infrastructure. The Times, allegedly quoting a source at the SBU, claimed the campaign was co-ordinated by the Chinese government. The SBU went on to deny The Times report.
