President Joe Biden and key cabinet officials were to host the chief executives of Apple, Google, Amazon and Microsoft along with leaders from the finance and utilities sectors, a senior administration official said.

The gathering comes after hacks and data breaches which have targeted a major US oil pipeline, a meatpacking company, and the Microsoft Exchange email system as well as ransomware attacks hitting various sectors.

“You will definitely be seeing a set of concrete announcements,” the official told journalists in a background briefing.
