    OpenAI targets small utilities with $1 billion cyber defense initiative (opens the original)

    Excerpt · Positive tone · English

    Read excerpt

    In a keynote speech during a summit at OpenAI’s headquarters attended by 300 enterprise security leaders and CISOs from Fortune 1000 companies, OpenAI President Greg Brockman announced Daybreak for Frontline Defenders, a new global initiative to help frontline defenders use frontier cyber AI to protect essential services in the United States and around the world. The initiative entails a $1 billion global commitment to expand subsidized access to Daybreak cyber models, training, technical suppor

    How China industrialized the infrastructure behind state hacking (opens the original)

    Excerpt · English

    Read excerpt

    Last week, the US Justice Department and FBI announced court-authorized seizures of domains hard-coded into two complementary hacking platforms known as “QScan” and “QTRouter,” used by Chinese state-sponsored hackers to target US critical infrastructure and other sensitive networks. A People’s Republic of China (PRC) state-sponsored group known as “QTFY,” employed by a corporation called China-based Nanjing Xinjiuwei Network Technology Company, created and operated QScan and QTRouter. Among the

    Critical infrastructure’s long, undefended tail exposed by UK energy attack (opens the original)

    Excerpt · English

    Read excerpt

    A cyberattack that forced a small British electricity generator offline for four days caused no power outage, threatened no part of the national grid, and may not even have been carried out by the Iran-linked hackers initially blamed. But the incident illustrates a consequential weakness in Western critical infrastructure. Thousands of small generators, water systems, and other industrial sites have aging operational technology — exposed programmable logic controllers, cellular modems, remote ma

    The AI harness is the new attack surface (opens the original)

    Excerpt · Critical tone · English

    Read excerpt

    Ask a security researcher what makes an AI agent dangerous, and the instinct is to talk about the model — what it will and won’t refuse, how easily it can be jailbroken, whether its weights can be trusted. That instinct is increasingly out of date. A growing body of security research — exploit demonstrations, independent red-teaming, and assessments by security researchers— points to the code sitting between the model and the world instead. That code, increasingly called the harness, wraps the m

    AI is making cybersecurity fundamentals more important than ever (opens the original)

    Excerpt · Critical tone · English

    Read excerpt

    When OpenAI disclosed that one of its models escaped a test environment and broke into Hugging Face’s systems on its own, headlines cast the incident as the start of a new era of AI-driven attacks. But the underlying cause of the incident was a familiar one: a misconfigured sandbox — the same kind of fundamental security failure that has enabled breaches for decades, with or without AI. AI systems are indeed already finding software vulnerabilities, tailoring social-engineering attacks, analyzin
