OpenAI Pledges $1bn to Bring its AI Cybersecurity Tools to Essential Services

OpenAI pledged $1bn to subsidize Daybreak cybersecurity model access for water, power, banking, government and nonprofit defenders, starting in the US with an MS-ISAC pilot.

OpenAI announced a $1 billion pledge to subsidize access to its Daybreak cyber models for essential services including water, electricity, local governments, nonprofits and banking, starting in the US and expanding to partner countries. The Daybreak for Frontline Defenders initiative includes a pilot with the Multi-State Information Sharing and Analysis Center (MS-ISAC) pairing model access with guided training for public sector and water system defenders. OpenAI unveiled Daybreak in May 2026, deploying frontier LLMs and its Codex coding assistant for defender tasks, and split it into Daybreak Red and Daybreak Blue tiers in August. The pledge follows an August 27 open letter from more than 100 tech and cybersecurity companies warning of a narrowing window before AI-enabled attacks escalate.

Hackers Actively Exploiting Gitea n-day RCE Vulnerability in the Wild to Hijack Instances

Chinese-speaking Red Heron actors mass-exploit Gitea n-day RCE CVE-2026-60004 to steal source code, credentials, and pivot into victim networks.

Acronis Threat Research Unit reports active in-the-wild exploitation of Gitea RCE CVE-2026-60004 (CVSS 9.8, versions 1.17-1.27.0, fixed in 1.27.1) by a Chinese-speaking actor dubbed Red Heron. The actor scanned 1,386 Gitea servers across seven countries, held a separate list of 477 Taiwan-based targets, and confirmed victims in Canada, Argentina, Taiwan, the US, and Sri Lanka. Intrusions deployed the JITTERLY Linux implant with the SIXZUT LD_PRELOAD rootkit, stole password hashes and SSH keys, and in one case gained root admin access to a three-node Proxmox cluster.
