The White House is bringing together three dozen nations, the European Union and a slew of private-sector companies for a two-day summit starting Monday that looks at how best to combat ransomware attacks.

The second International Counter Ransomware Summit will focus on priorities such as ensuring systems are more resilient to better withstand attacks and disrupt bad actors planning such assaults.

A senior Biden administration official cited recent attacks such as one that targeted the Los Angeles school district last month to underscore the urgency of the issue and the summit. The official previewed the event on the condition of anonymity.
