‘Copy Fail’ Logic Flaw in Linux Kernel Enables System Takeover securityweek.com/copy-fail-logi…

By AI engineers. For AI teams.

Threat actors seeking unauthorized access to operational technology (OT) systems have exploited trusted connections through IT systems, third-party partnerships, and the internet. Zero Trust offers a modern, adaptive approach to #cybersecurity by eliminating implicit trust and continuously validating access based on identity, context, and risk. This guidance document, authored by @FBI, @CISAgov, and other partners, provides recommendations for OT owners and operators to implement Zero Trust principles while considering the unique constraints and challenges of OT environments. 🔗 ic3.gov/CSA/2026/26042…

New internet assets are scanned within an hour, with attackers actively probing vulnerabilities and launching credential attacks within 6–12 hours. Continuous ASM paired with human validation uncovers hidden risks fast. #AttackSurface #APIExposure ift.tt/sGDXEfl

‼️Copy Fail (CVE-2026-31431) is a Linux privilege escalation bug that lets any local user get root using a 732-byte Python script, and itworks on basically every major Linux distro shipped since 2017. Website: copy.fail Write-up: xint.io/blog/copy-fail… GitHub: github.com/theori-io/copy… It's a logic flaw in the kernel's crypto code (authencesn via AF_ALG and splice()) that allows a small write into the page cache, which can be used to tamper with a setuid binary like /usr/bin/su. Think how bad this is going to be for shared environments like Kubernetes, CI runners, and cloud sandboxes, where it enables container escape and tenant-to-host compromise. Found by Theori's Xint Code scanner, patched in the mainline kernel, and publicly disclosed on April 29, 2026; if you can't patch right away, the recommended workaround is to disable the algif_aead module.

Implementing zero trust in OT environments requires a holistic approach, tailored adaptation, & collaboration between IT, OT, & cyber teams. Our joint guide provides actionable steps to help enhance the security & resilience of your OT. Learn more 👉 go.dhs.gov/iaE

we're starting rollout of GPT-5.5-Cyber, a frontier cybersecurity model, to critical cyber defenders in the next few days. we will work with the entire ecosystem and the government to figure out trusted access for cyber; we want to rapidly help secure companies/infrastructure.

🛡️ OpenAI Releases 5-Point Action Plan to Strengthen AI-Powered Cyber Defense Source: cybersecuritynews.com/openai-5-point… OpenAI has published a comprehensive cybersecurity action plan outlining a five-pillar strategy to equip trusted defenders with advanced AI capabilities while preventing adversarial misuse. Artificial intelligence is fundamentally reshaping the cybersecurity landscape and not just for defenders. Malicious actors are already leveraging AI to improve phishing campaigns, automate reconnaissance, accelerate malware development, evade detection, and scale cyber operations at unprecedented speed. #cybersecuritynews #OpenAI

🔄 Threat actors regularly re-emerge under different identities. New agentic capabilities in Google Threat Intelligence and the dark web monitoring module streamline investigations, linking multi-alias actors and mapping operations. 🔗 Learn more: goo.gle/48ufZj8

We've released a new 5-point action plan for strengthening cyber defense. AI is reshaping cybersecurity. The same capabilities that help defenders may be used by malicious actors. One approach is to treat these systems as too dangerous for broad defensive use and limit them to a very small number of approved partners. We think that misses the central challenge. Attackers won’t wait. Existing models are already useful for many cyber workflows and capabilities will keep advancing. Criminal groups will adopt whatever tools are available. The best way to reduce national risk is to responsibly equip and accelerate trusted defenders faster than adversaries can adapt. Check out our plan ⬇️ openai.com/index/cybersec…
