China-linked hackers hit Taiwan in unprecedented ‘autonomous’ AI cyber attack

Summary

China-linked hackers used AI agents to conduct simultaneous reconnaissance and break-ins against targets in Taiwan. The operation marks a new phase in which software can manage more of the attack process with limited human direction.

The decisive shift is operational scale: AI agents can run multiple intrusion attempts at once,

Terabytes of credentials leaked in massive supply-chain attack

Summary

A compromised AI package was used to scrape and exfiltrate terabytes of credentials from roughly 2,500 users.

The breach turned a single software dependency into a collection point for credentials across thousands

Architecting Multi-Cloud Networks to Survive Cryptographic Migrations under DORA Rules

Summary

Post-quantum readiness must be managed as an operational-resilience program spanning multi-cloud networks, data, and cryptographic dependencies. The approach links cryptographic migration planning to the resilience and governance requirements established by DORA.

The decisive shift is from treating post-quantum cryptography as a future technology upgrade to treating

Coalition for Health AI Mounts Effort Against Cyberattacks

Summary

The Coalition for Health AI has created a Health AI Cybersecurity Work Group to develop practical, peer-developed guidance on cyber risks and readiness for frontier AI models in healthcare. The group aims to give healthcare organizations a common framework for managing attacks against increasingly capable AI systems.

Healthcare AI governance is expanding from responsible use and model quality to operational cybersecurity. The

Prompt Injections for Defense

Summary

Researchers found that embedding malicious-looking instructions alongside passwords, cryptographic keys, and other AWS secrets can disrupt AI hacking agents. The instructions push the agents toward actions their safety guardrails prohibit, causing them to stop rather than extract or use the secrets.

The defensive shift is to turn an attack technique into a trap for autonomous hacking

Why it matters

As AI agents begin probing cloud environments, defenders can target the agents' safety controls as well as the infrastructure they attack.
