Major tech companies call for defensive surge

OpenAI, Anthropic, Microsoft, Alphabet, Amazon and more issued a joint letter urging industry and government to bolster defenses against an impending wave of AI‑enabled cyberattacks.

Leading AI and cloud firms have banded together in a rare joint letter, warning that the next wave of cyber threats will be powered by artificial intelligence and urging both the private sector and governments to launch a “defensive surge.”

Why AI is reshaping cyber threats

The signatories — including OpenAI, Anthropic, Microsoft, Alphabet, Amazon and several other major tech companies — argue that AI tools can automate the discovery of vulnerabilities, craft convincing phishing messages and even generate malicious code at unprecedented speed.

According to the letter, attackers are already experimenting with large language models to bypass traditional security filters, making it harder for existing defenses to keep pace.

Key recommendations from the coalition

Increase funding for AI‑focused security research and threat‑intelligence sharing.
Mandate regular AI‑risk assessments for critical infrastructure and high‑value enterprises.
Develop standardized guidelines for the responsible deployment of generative AI in corporate environments.
Strengthen public‑private partnerships to accelerate the rollout of advanced detection tools.

The letter also calls for clearer regulatory frameworks that balance innovation with security, urging policymakers to act before AI‑enabled attacks become commonplace.

Industry response and next steps

Several of the signatories have already pledged to share threat data through existing platforms such as the Cybersecurity and Infrastructure Security Agency’s (CISA) Automated Indicator Sharing (AIS) program, and to invest in AI‑driven defense solutions.

Analysts note that coordinated action could reduce the time it takes to detect and mitigate AI‑generated threats, potentially saving billions in damage.
