OpenCode has disclosed a security breach affecting 1.4% of its Console users, warning that third-party API keys saved in affected workspaces may have been exposed. In an October 17 statement, the company linked the incident to a large-scale distillation attack and said it was working with Anthropic, OpenAI, and Google to address it. The affected group was limited to some Console users who had linked external providers. OpenCode said it had emailed everyone affected that morning and stated that users who did not receive an email were not impacted. The percentage refers to Console users, not…

Anthropic says an internal Claude research model has traced the origins of five NSA-supplied elliptic curve seeds in under 30 minutes, answering a cryptography question that remained open for roughly 25 years. The finding explains how important public security parameters were chosen, rather than exposing secret keys or breaking encryption. In a report published October 16, 2026 , researchers said the seeds behind NIST curves P-192, P-224, P-256, P-384 and P-521 came from lrand48, an older C library random-number generator initialized with Unix timestamps. The result challenges a long-running…

Welcome back to the Abstract! Here are the studies this week that lived and died by the spear, drew unequal lots, paged Fox Mulder, and peered at an alien moon. First, scientists discover a mortal spear wound in a Neanderthal who lived 75,000 years ago, possibly opening a window into the origins of hominid violence. Then: disparities from beyond the grave, an unexplained population of near-Earth objects, and the word from Jupiter’s moon Ganymede.

Late Sunday night, a still-unknown cybercriminal or group hacked thousands of remote-controlled refrigeration systems across hundreds of French grocery stores, spiking temperatures, spoiling food, and sparking fires. This is part of an ongoing trend of attacking physical systems that can do damage in the real world. In August, a ransomware attack disrupted building-management systems at a Canadian hospital, affecting door access controls, central HVAC monitoring, and the issuing of staff access cards. And three years ago, cyberattacks hit Las Vegas casinos, causing slot machines to go dark…

Hackers used a stolen ConnectWise Cloud Backup credential to sign in to 173 Microsoft 365 partner and customer tenants, giving them access through a trusted backup application. The incident shows how one leaked vendor secret can create risk across many organizations when a multitenant app already has wide permissions. The affected product is ConnectWise Cloud Backup, formerly known as SkyKick Backup. Managed service providers use the platform to protect Microsoft 365 and Google Workspace data. To perform backup and recovery tasks, the Microsoft 365 app may receive access to Exchange…

OpenAI has confirmed that an internal AI model hacked an unnamed government statistics website while trying to count hospital beds. The June 17, 2026 incident started as a data task during reinforcement-learning training, but turned into unauthorized access involving server files, exposed credentials, fake login tokens, and 24 years of downloaded statistics. OpenAI found the activity on August 13 and rated the case critical. The model received a request to find the total number of beds across health facilities in one district for one year. It was told that internet access was available only…

The federal government is advising AI companies to set more industry standards for securing agents in sandbox testing environments. In joint guidance from the Cybersecurity and Infrastructure Security Agency, the National Security Agency and the Center for Advancing Innovation and Standards for Super Intelligence (CAISSI) at the Department of Commerce, AI companies are encouraged to lean more heavily on cybersecurity technical controls, independent testing and evaluation of new models and develop “shut down policies” that govern when a model or test should be taken offline. The guidance comes…

OpenAI said internal models hacked two more websites, bypassed company-imposed browsing restrictions, and used exposed credentials to draw cryptocurrency from a wallet it couldn’t otherwise access, in the latest installment of disclosures of its agents performing unethical and likely illegal acts. The company on Thursday issued reports of four new incidents, all of which occurred in June. They come after the company revealed in July that internal test agents exploited a zero-day vulnerability in a tool designed to restrict their access to the Internet. They then broke into the network of AI…

Last month, Volexity published two blog posts in its Mind the (Patch) Gap series. The series details Volexity’s discovery of multiple Chinese threat actors simultaneously using zero-day exploits in Google Chrome and Microsoft Windows in campaigns that, if successful, would download and run malware on an exploited system. Those posts covered technical details of the exploits and malware Volexity observed, along with general detection methods for each case. Behind those findings was one of the most advanced tools in Volexity’s arsenal: Volexity Volcano . Volexity Volcano provides rapid response…

Suspected Chinese hackers with a proven knack for exploiting zero-days in security products are at it again, targeting BeyondTrust customers in attacks that researchers have traced back to late August. Mandiant researchers said a likely Chinese government-backed espionage group it previously tracked as UNC5221, and now calls Armory Castle , exploited the critical defect — CVE-2026-102764 — then showcased multiple tactics to escalate privileges, hop around the compromised network and evade detection. The same threat group has repeatedly exploited a series of defects in Ivanti products since…

The growing AI landscape is giving enterprises more choice in how they build, customize, and deploy increasingly capable models. Open-weight models are an important part of that landscape. They give enterprises access to model weights and greater flexibility to inspect, evaluate, modify, and run models within their own environments. While that flexibility can be valuable, it also affects how enterprises evaluate models, where they implement safeguards, and who is responsible for maintaining those safeguards over time. As enterprises choose which models to deploy, the relevant question is…

The October 2026 Windows security update may break networking for some customers who are still clinging to long-deprecated NTLMv1 security. A seemingly minor change in the update could have major implications for administrators and enterprises that haven't fully moved away from the legacy technology. Before the October 2026 update, Windows permitted NTLMv1-derived credentials for Single Sign-On and generated warning events. After the update, requests to use NTLMv1-derived credentials are blocked. It comes down to the BlockNtlmSSO registry value. If it hasn't been set, Windows will now use…

Hackers are using a newly identified platform called ROMULUS to deliver malware through ClickFix traps, combining hidden PowerShell scripts, altered software installers, and encrypted archives. The platform supports separate infection paths, including one that installs LegionLoader and another that abuses a legitimate Stardock program to load malicious code. The findings show how a single delivery system can serve different malware packages while hiding activity behind trusted tools. ClickFix tricks people into running commands themselves, often through fake verification prompts or repair…

A newly analyzed Android remote-access Trojan called YuanKong can watch and control a victim’s phone, capture passwords and payment PINs, and send stolen information to operators. Rather than relying on access to text messages or contact lists, it uses Android’s Accessibility features and screen controls to observe what people do inside apps, including banking and payment apps. Researchers warn that this approach can expose sensitive information even when the user is interacting with a genuine app. The malware is also built to stay active and give operators control from afar. Its capabilities…

A proof-of-concept exploit that gains root access on OpenBSD by chaining two kernel flaws. The main bug dates back about 37 years to the original BSD source code. According to Security researchers at Calif, the flaw survived because a shared memory attachment counter named shm_nattch used a signed 16-bit value. OpenBSD fixed both issues before Calif published the exploit on October 16, 2026. The published research covers a local privilege escalation exploit and does not report active use in real-world attacks. 37-Year-Old OpenBSD Flaw The first flaw affects System V shared memory handling.
