US companies should be on the lookout for security nasties from Ukrainian partners following the digital graffiti and malware attack launched against Ukraine by Belarus, the CISA has warned.
"If working with Ukrainian organizations, take extra care to monitor, inspect, and isolate traffic from those organizations; closely review access controls for that traffic," added CISA, which also advised reviewing backups and disaster recovery drills.
On Monday Ukraine attributed a headline-grabbing mass defacement of government websites to Belarus, the attacks having taken place late last week.
The CISA warning came after Microsoft published details of wiper ransomware deployed by a hitherto unknown criminal crew, later named as UNC1151.
The CISA warning is a reminder that bears repeating; NotPetya began in Ukraine and swept around the world, causing headaches for IT departments that lasted for weeks afterwards.
In years gone by smaller countries were said to cough when America caught a cold; today it's your networks getting infected if Ukraine catches a virus.
