Executives at major artificial intelligence companies, including OpenAI and Anthropic, are reportedly preparing “day after” scenarios in the event of a serious AI-related cyberattack, according to reporting cited by CBS News and Decrypt. The outlets describe internal planning that focuses on how companies would respond to potential fallout and what actions might follow.

Decrypt says the rehearsals include “war-gaming” political impacts and preparation for quickly briefing members of Congress if needed. CBS News similarly characterizes the effort as contingency planning for catastrophic outcomes. While both sources agree on the existence of behind-the-scenes preparation, they differ in emphasis: Decrypt highlights legislative and political consequences more directly, while CBS frames the work more broadly as planning for catastrophic cyberattack fallout.

The reporting does not specify the nature of any particular threat or the timing of the alleged planning. It also does not provide details about whether any attack has occurred, only that executives are creating contingency plans for potential worst-case scenarios.
