Several Ukrainian critical infrastructure organizations—including Naftogaz, Ukrposhta, DSBT, and Ukrzaliznytsia—were targeted in cyberattacks this week, causing disruptions to data center operations, postal services, transport safety systems, and rail services; attribution is unclear, although the group calling itself the National Cyber Army claimed responsibility for the DSBT attack and national cybersecurity authorities are investigating.
