Ukraine's government emergency response team CERT-UA has warned that malefactors are sending emails to Ukrainians and Ukrainian government organizations with the subject line "Urgent! Azovstal Unblocking Urgent! Unblocking Azovstal." Sheets have an attachment in the form of an XLS document "Military on Azovstal.xls", which contains a macro. When you open the document and activate the macro, the computer will be affected by the Cobalt Strike Beacon malware.
