⚠️ Three Zhejiang University researchers describe "Bit2Watt," a technique showing that ordinary GPU workloads can be modulated to produce fast, controllable power oscillations. They demonstrate two methods: a synthetic kernel (SWMA) that toggles compute intensity and an LLM-training modulation (LTMA) that embeds oscillations into real training runs. Experiments measured kHz-range power components on GPUs and simulations showed that synchronized modulation across many devices could destabilize local grids and create denial-of-service or covert channels. The work highlights a visibility gap between compute and power operators and suggests combined hardware and monitoring defenses.

🔒 The U.S. Cybersecurity and Infrastructure Security Agency (CISA) has ordered federal agencies to patch systems by Saturday to mitigate active exploitation of a critical Oracle E-Business Suite vulnerability, tracked as CVE-2026-46817. The flaw in the Oracle Payments File Transmission component allows unauthenticated HTTP access leading to system takeover in low-complexity attacks. Oracle issued fixes in its May 2026 Critical Security Patch Update and urged immediate patching, while security firms and CISA have observed active exploitation. Shadowserver reports over 1,000 Internet-exposed Oracle EBS instances, many in the U.S., prompting CISA to add the flaw to its list of known exploited vulnerabilities and mandate remediation under BOD 26-04.

🛡️ The US government has launched Gold Eagle, a program led by CISA, the Treasury and the Department of Defense to speed detection and remediation of software vulnerabilities.

Google Cloud commits to constructive engagement with regulators and to help customers meet operational resilience and third‑party risk requirements.

🔐 Amazon Web Services EMEA Sarl (AWS) has been designated a critical third party (CTP) to the UK financial sector under the CTP regime that came into force on January 1, 2025. The regime gives the Bank of England, PRA, and FCA powers to set requirements and exercise direct oversight over designated providers. AWS will self-assess its designated Systemic Third-Party Services (STPS) against the criteria and engage with regulators while supporting customers’ operational resilience.

🔒 The UK’s NCSC and DSIT unveiled a blueprint called Cyber Shield to deploy autonomous AI agents that detect and neutralize cyberattacks at machine speed. The plan uses cooperating “red” and “blue” agents to identify weaknesses, detect threats and progressively automate remediation while operating under organizational control. The initiative emphasizes explainable and federated AI, industry partnerships, and a staged rollout beginning with government and critical sectors.

🔒 Ubiquiti released updates addressing seven critical UniFi OS vulnerabilities, including a maximum-severity command injection flaw (CVE-2026-50746) in the UniFi Connect Application. The flaw affects versions 3.4.16 and earlier and could allow a network-based attacker to execute commands on the host. Users are advised to upgrade UniFi Connect to version 3.4.20 or later. Six additional critical issues across UniFi Talk, Access, Protect, UniFi OS Server, and multiple devices were also patched.

🔒 The UK National Cyber Security Centre (NCSC) has launched the Cyber Shield initiative to build a national cyber-defence capability powered by agentic AI. The project will use coordinated red and blue agents to discover and mitigate vulnerabilities at scale, enable national automated scanning, and support real-time intelligence sharing. The NCSC says success requires partnerships with government, critical infrastructure and frontier AI providers.

🔒 Over 900 Oracle E-Business Suite (EBS) instances were found exposed online amid active attacks exploiting a critical File Transmission flaw in Oracle Payments (CVE-2026-46817). The vulnerability permits unauthenticated HTTP takeover, and Oracle released patches in its May 2026 Critical Security Patch Update, urging immediate remediation.
