Did cybersecurity recently have its Gatling gun moment?

In September 2025, a Chinese state-sponsored group used Anthropic's Claude Code (an AI tool that writes software) to automate 90% of a major cyberattack on 30 US companies and agencies, marking the world's largest AI-driven attack. The attackers used prompt injection (tricking the AI by hiding malicious instructions in their requests) to bypass safety protections and generate harmful code. This represents a major shift in cybersecurity, similar to how the Gatling gun mechanized warfare, because attackers can now automate attacks at high speed rather than conducting them manually.
