OpenAI spends $1 billion to expand Daybreak to defend power, water, and banking

The New Stack 1 month ago 24 ● 2 sources

OpenAI announced Daybreak for Frontline Defenders, expanding its Daybreak governed cyber defense stack to help frontline defenders protect critical services worldwide. The initiative continues OpenAI’s $1 billion commitment to expand subsidized access, training, technical support, and partnerships, including a U.S. pilot with MS-ISAC. Access and support for defensive cyber AI tools expand for state and local cyber teams, including coverage focused on systems used for water, electricity, local government, and banking.

Abliteration.ai is making a business out of removing AI guardrails

TechCrunch 1 month ago 49

Abliteration.ai offers an online service that hosts open-weight AI models after removing their guardrails and refusals, letting users query them via web or API. A free test account let TechCrunch quickly query an abliterated version of Z.ai’s recently released GLM-5.3. The shift turns a widely available research practice into commercial, easy-to-access tooling for offensive cyber and biological harmful requests, raising safety and policy concerns while defenders argue it helps red teaming.

Virtual patching closes the gap as AI erases the patch window

SiliconANGLE 1 month ago 7

F5 partnered with CrowdStrike to embed a Falcon sensor on its BIG-IP network perimeter appliances and use virtual patching as exploitation time between disclosure and patching shrinks. The integration’s performance overhead was measured at 1% to 2%. Virtual patching shifts defenses to network-layer shielding while real fixes are tested and rolled out, and F5 is also applying similar guardrails to AI gateways.

Agentic AI is compressing attacker intrusion timelines to minutes

SiliconANGLE 1 month ago 10 ● 5 sources

Agentic AI has been adopted by attackers, with Crowdstirke reporting intrusions carried out by agentic adversaries in real-world extortion, espionage, and hacktivist activity. In the last 30 days, CrowdStrike tracked 26 agentic adversaries, up from fewer in the prior year, and one case involved 1,100 commands in 58 minutes. Defenders now have less response time as attackers complete operations faster, shifting security efforts toward increasing the cost of intrusion through actions like botnet disruption.
