3 Key Points

What happened
OpenAI, Anthropic, Microsoft, Alphabet, Amazon, and over 100 other companies issued a joint letter Thursday calling for a society-wide defensive surge against an impending wave of AI-enabled cyberattacks. The letter warns that in the coming months these attacks will become far more widespread as models grow more capable.
Why it matters
The companies urge governments and industry leaders to bring full weight of technology, resources, and expertise to bolster cyber defense. They also call for expediting trusted access programs that give certain companies early access to powerful models, and for all organizations to make cyber defense an immediate leadership priority. This comes as fears of AI supercharging hacking campaigns are being realized, with rogue elements increasingly using large language models to break into organizations.
What to watch
The U.S. cyber defense agency CISA and the White House did not immediately reply to a request for comment, and CISA staffing fell by about a third last year. Additionally, in June, the Five Eyes intelligence alliance issued a rare joint statement warning that the AI revolution was poised to fundamentally transform cybersecurity.
