OpenAI has announced plans to conduct frontier model training with no live internet access, as it resumes reinforcement learning (RL) training and internal inference of its most advanced AI models. "Based on the current state of alignment research, monitoring systems, and the security of internet infrastructure, we believe the responsible approach is to conduct frontier model training with no internet access," the artificial intelligence (AI) company said . "We've implemented this policy and will maintain it until advances in these safeguards justify broader internet access." OpenAI said models' growing capabilities can have the side effect of them getting much better at devising ways around environmental restrictions to escape containment and perform unintended actions. This can involve the model exploiting a software flaw or misconfiguration to reach the live internet, or finding unauthorized ways to communicate with agents in other sandboxes. Late ...

A memory-corruption flaw in Google's Brotli decoder sits in many programs that unpack Brotli-compressed data, among them Bun, Microsoft's .NET, the Python Brotli and brotlicffi packages, and Envoy proxies set up to decompress Brotli. Tracked as  CVE-2026-111497 , the flaw allows crafted compressed data to overwrite past the end of a buffer and corrupt a program's memory, potentially causing a crash, a memory leak, or the execution of attacker-controlled code. Imperva researchers have shown that code can run on one unpatched Node.js build . The same has not been demonstrated on the other software, and no real-world attacks have been reported. The flaw was  first disclosed on October 21 , when Node.js and Google shipped fixes, and more have followed product by product since. Because the bug is in Google's decoder and each program ships its own copy of it, every one has to update that copy on its own. Brotli is a compression format from Google, used ...

LiteLLM on Friday revealed that an Agent Platform master key accidentally published to a public GitHub repository in late May 2026 ultimately allowed the threat actor to push a malicious version of the popular Python package. "On May 27, 2026, a configuration file was committed to the public LiteLLM-Labs/lite-harness repository which inadvertently contained the master key to a deployment of the LiteLLM Agent Platform, an open source tool we use for orchestrating agents," LiteLLM's Oliver Jensen and Mateo Wang said . "The error was quickly identified, the commit force-pushed over, and we identified the exposed keys as requiring revocation. However, key revocation did not occur for the master key." LiteLLM said the unknown attacker (operating from "69.48.229[.]143") used this unrevoked key on October 10, 2026, to gain access to the Agent Platform and extracted a GitHub CLI OAuth token the service was configured with to allow self-hosted cloud a...

Google has updated its privacy policy to spell out that using personalized artificial intelligence (AI) features in Search or Gemini could allow the company to serve targeted ads to users based on their activity on other connected Google services. "You may choose to allow certain Google services, including services like Search or Gemini Apps, to access data from other Google services you use, such as Google Photos and Workspace apps like Gmail and Drive, in order to provide you with a more personalized experience, subject to the policies and settings of the accessing service," reads a policy update effective October 16, 2026. "For example, Search may process some of the data that you allow Search to access to personalize content, including ads." Google also notes in its revised policy that "We don't show you personalized ads based on your content from Drive, Gmail, or Google Photos, unless you choose to make data from these services available to ...

Between November 2025 and March 2026, the Dutch security firm Eye Security pushed more than 2 million updates to computers it did not own to switch off a background updater that it said could have allowed an outsider to take over the machine. The updater belongs to Time4Popcorn , an abandoned copy of Popcorn Time, a free app that streamed pirated films and TV over BitTorrent. Popcorn Time was popular about a decade ago, and the original shut down in 2014, but several copies kept running under the same name. A separate, legal project that took the Popcorn Time name in early 2025 is unrelated to it. Eye Security, which monitors client networks for threats, found the updater during a routine threat hunt: a program called Updater.exe on one client's laptop kept trying to reach a web address that was no longer registered. The firm registered the address itself to see what would connect, and about 50 requests a second poured in. It later laid out the operation, which it named O...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Friday added two vulnerabilities impacting Collabora Online Built-in CODE Server and Arista VeloCloud Orchestrator (VCO) to its Known Exploited Vulnerabilities ( KEV ), citing reports of active exploitation in the wild. The critical-severity vulnerabilities are listed below - CVE-2026-110447 (CVSS score: 9.2) - An operating system command injection vulnerability in Collabora Online – Built-in CODE Server (aka richdocumentscode) when used within the NextCloud platform that could allow remote code execution via "proxy.php" when the CODE local document server isn't running. (Fixed in September 2026 in version 26.4.303) CVE-2026-114625 (CVSS score: 9.9) - An SQL injection vulnerability in on-premise versions of Arista VeloCloud Orchestrator that could allow a remote attacker to access privileged internal functionality. (Fixed in October 2026  in versions 5.2.3.18, 6.1.3.10, and 6.4.2.12) As r...
