Google on Wednesday took the wraps off Gemini 4 Carbon , its latest frontier model with state-of-the-art cybersecurity and long-horizon capabilities. "It shows significant gains across coding and agentic tasks as well as across key capabilities critical for cybersecurity defense, landing a firm lead in SEC-bench Pro (88.2%) for finding vulnerabilities, ExploitGym (54.8%) for exploitation, and CWE-bench (71.0%) for patching," Koray Kavukcuoglu, senior vice president of Google DeepMind and chief AI architect at Google, said . On the Artificial Analysis Intelligence Index benchmark, Carbon leads with a score of 59, surpassing Anthropic's Claude Opus 5.5 (58), OpenAI GPT-6 Astra (57), GPT-6.1 Sol (55). One of the core focus areas is cybersecurity, where the latest iteration reportedly delivers significant performance improvements across the board, including vulnerability detection, validation, and remediation. Carbon is also twice as likely to generate secure code ver...

Security teams have spent years trying to detect threats faster. AI is changing the harder part: how much time defenders have left to act. Advanced AI models can now help attackers discover vulnerabilities, generate exploit code, and move through weaknesses faster than traditional security processes were built to handle. The challenge is no longer just finding another vulnerability or generating another alert. It is knowing which exposures matter, what an attacker can reach, and which issues need to be fixed first. That is the focus of next week's webinar, How to Build AI Threat Readiness Across Your Security Operations , featuring an expert from Wiz. The session will show how security teams can improve visibility, prioritize real risk, and shorten the path from detection to remediation. Most security teams already have plenty of data. They have vulnerability findings, cloud alerts, identity signals, application telemetry, and threat detections. The harder problem is conne...

A flaw in Telegram for Android allowed an attacker to run code on a victim's phone via a voice call once the victim answered, according to security startup NebuSec. The attacker needed only an ordinary Telegram account. Telegram fixed the flaw in version 12.10.4 of the app, released in late September, and NebuSec  disclosed it on October 29 . The flaw can be triggered in every version from 8.6.2 through 12.10.3, NebuSec's co-founder and chief executive said in an email to The Hacker News. Those versions came out between March 2022 and September 2026. The company confirmed it in private phone calls on ARM64-based phones and has no evidence so far that it directly affects Telegram's iOS and desktop apps or group calls. Anyone using Telegram for Android should make sure the app is on version 12.10.4 or later. The version number appears at the bottom of the app's Settings page. The flaw had no CVE identifier as of October 29. The Hacker News has asked NebuSec an...

Cisco has released patches to address a high-severity security flaw in Secure Firewall Adaptive Security Appliance (ASA) Software and Secure Firewall Threat Defense (FTD) Software that it said has been exploited in the wild. The vulnerability, tracked as CVE-2026-76418 , is rated 8.6 on the CVSS scoring system. Successful exploitation could allow an unauthenticated, remote attacker to cause the device to reload unexpectedly, resulting in a denial-of-service (DoS) condition. According to Cisco, the issue is rooted in the Remote Access SSL VPN service of ASA and FTD software. "This vulnerability is due to logic errors when secondary authentication is configured on a tunnel group," it said in a Wednesday advisory. "An attacker could exploit this vulnerability by sending a crafted request when connecting to the SSL remote access VPN. A successful exploit could allow the attacker to cause the affected device to reload, resulting in a DoS condition." The network ...

GitHub has announced that it's introducing a new package firewall as a preview to block installation of suspicious npm packages during installation time. "The firewall inspects both metadata requests and package downloads for signs of malicious activity, acting as an install-time policy gate," GitHub said . The feature, which currently supports only npm packages, is available in public preview for all GitHub Enterprise Cloud customers, including data-resident GitHub Enterprise Cloud. According to the Microsoft subsidiary, the firewall is placed between endpoints or internal registries and the upstream package repositories so as to deter malware attacks that compromise systems when packages are installed. This behavior can expose users to severe security risks, especially when artificial intelligence (AI) agents and CI runners automatically install dependencies to complete a task or build without their explicit permission. The idea is that endpoints like coding ...

An attacker tried to exploit a critical GitLab vulnerability on the Alpine Linux project's own GitLab server a week after GitLab  released a fix , Alpine Linux  said  on 28 October. The flaw, CVE-2026-97229 (CVSS score: 10.0), can let an attacker run code on a GitLab server through a crafted regular expression in a CI configuration. Alpine found no evidence that the attack worked but cannot rule it out, so it rebuilt the server from scratch and reset every account's password. GitLab's fix  is a set of patches to the Ruby that GitLab ships in its own packages and container images. Alpine's GitLab image used standard Ruby, so upgrading the server to GitLab 19.3.6 on 22 October did not fix the flaw. For anyone running GitLab on their own Ruby, built from source or in their own container image, "upgrading GitLab is not enough," Alpine said. Those servers also need  Ruby 3.3.13, 3.4.12, 4.0.9 or later , and users of Alpine's alpinelinux/gitlab image...

Hackers exploited a critical Cisco Catalyst SD-WAN flaw, fixed in February, to plant custom malware inside the systems that control an organization's SD-WAN network. The malware, called KeyDrift , is designed to copy the keys that encrypt traffic between sites and store them for later use,  Cisco Talos said  on October 28. Talos calls the attacks historical but does not specify when they occurred or whether any keys were sent. The flaw is tracked as  CVE-2026-20127  and has a CVSS score of 10.0. It allows an unauthenticated remote attacker to bypass authentication and gain administrative privileges on these control systems. On a Controller, the attacker can log in as a high-privileged internal account that is not root. When Cisco  disclosed the flaw in February , Talos tracked its exploitation as UAT-8616, a cluster of activity it said went back to at least 2023. In  Cisco's traditional key exchange , each SD-WAN router periodically generates an AE...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Wednesday added a security flaw impacting Broadcom VMware ESX to its Known Exploited Vulnerabilities ( KEV ) catalog, after CrowdStrike revealed that it had been weaponized by a China-nexus threat actor known as Warp Panda in attacks targeting the U.S. legal sector. The vulnerability in question is CVE-2026-41709 (CVSS score: 2.7), an a case of insufficient logging that could permit permit a malicious actor with admin access to perform certain operations without being logged. In an advisory released in July 2026, Broadcom revealed that the issue was addressed in the following versions - VMware Cloud Foundation SXi-9.1.0.0-25370933 and ESXi-9.0.2.0100-25595025 VMware vSphere Foundation SXi-9.1.0.0-25370933 and ESXi-9.0.2.0100-25595025 VMware ESX ESXi80U3j-25429389 VMware Cloud Foundation 5.2.4 VMware Telco Cloud Platform ESXi80U3j-25429389 The development comes in response to CrowdStrike...

Palo Alto Networks on Wednesday warned that threat actors are exploiting the recently patched PHP2Shell vulnerabilities against publicly-accessible management interfaces. "Active exploitation has been observed targeting the Palo Alto Networks management interface exposed to the internet," the network security company said in an update to its advisory. The vulnerabilities, tracked as CVE-2026-109618 and CVE-2026-109619 (CVSS scores: 9.2), allow attackers to achieve unauthenticated remote code execution on systems running affected versions of PHP. The issues were patched upstream by the PHP Foundation on October 21, 2026, in versions 8.5.12, 8.4.27, 8.3.36, and 8.2.35. The development comes days after Israeli cybersecurity company Dream said it observed a suspected China-nexus threat actor weaponizing the flaws in conjunction with a local privilege escalation bug in the Linux kernel, tracked as Fragnesia (CVE-2026-46300, CVSS score: 7.8), to root 25 servers across t...

The China-nexus cyber espionage group known as Volt Typhoon has been attributed to a now-disrupted covert access network dubbed Silent Train that has been put to use for zero-day exploitation and strategic access. "First identified in late 2023, Silent Train uses rotating chains of compromised SOHO, IoT, and enterprise infrastructure," Lumen Technologies Black Lotus Labs said in a report shared with The Hacker News. "It employs anti-forensic techniques, compartmentalized operations, and post-operation cleanup to minimize detection and attribution." Its main purpose is to facilitate critical attack phases like vulnerability exploitation, credential access, data exfiltration, and to maintain continued access to victim environments. The activity stands out for two main reasons - It singled out entities that could provide scalable access to downstream customers, sensitive networks, or strategic programs. It targeted endpoint management platforms, network...

A chain of logic flaws, with no memory corruption, can turn a malicious web page into code running on a Windows computer outside Microsoft Edge's sandbox, a security researcher has shown. Orange Tsai of DEVCORE published the full method on October 28, five months after the chain won $175,000 at the  Pwn2Own Berlin contest  in May. Microsoft fixed the Edge bugs the day after the contest, so an up-to-date browser is not at risk. A browser sandbox is the wall that keeps a web page's code inside the browser and off the rest of the computer. Breaking out of it, and then running a program, is what turns a web bug into full control of the machine. Browser escapes like this almost always rely on memory corruption. This one used none. In his  write-up , Tsai describes a chain built solely from logic errors in how Edge and Windows handle ordinary features, and he says the whole exploit is under 100 lines of code. The result is a universal cross-site scripting (UXSS) primit...

Cybersecurity researchers have disclosed details of what appears to be an artificial intelligence (AI)-assisted attack orchestrated by a suspected China-nexus threat actor that has leveraged the PHP2Shell vulnerabilities to breach exposed systems. The activity, which was observed on October 25, 2026, involved an attacker combining PHP2Shell with a kernel privilege escalation exploit to root 25 servers, including three systems in a U.S. government-affiliated environment. "The affected devices run specific versions of a large vendor's firewall software," cybersecurity firm Dream said . "The attacker then launched attacks against Active Directory. The recovered artifacts confirm credential extraction and directory enumeration." The name of the affected vendor was not disclosed, but the Israeli company said it notified the entity. The attack chain essentially brings together two sets of vulnerabilities impacting PHP and the Linux kernel - PHP2Shell , ...

Threat actors are beginning to probe for a newly patched critical vulnerability in Oracle E-Business Suite (EBS), according to threat intelligence firm Defused Cyber. The vulnerability in question is CVE-2026-101767 (CVSS score: 9.8) , a case of improper authentication in the Oracle Application Object Library of Oracle E-Business Suite. It was patched by Oracle last week as part of its Critical Patch Update . Security researchers Brandon Peterson, Jimi Sebree, and Noah King of Horizon3.ai have been credited with discovering and reporting the flaw to Oracle on July 24, 2026. "Our Oracle E-Business Suite decoys recorded exploratory exploits against CVE-2026-101767, an unauthenticated SQL injection in EBS's Thin Client Framework servlet that chains to remote code execution, this morning, October 27," Defused Cyber said in an X post. In an advisory for the vulnerability, Horizon3.ai described it as an unauthenticated SQL injection vulnerability that could be chaine...

A critical 16-year-old flaw in EDK II , the open-source code that most hardware makers use to build UEFI firmware, can allow an attacker to run code on a machine before its operating system loads, but only while the machine is booting over the network. UEFI firmware is the software that runs first when a computer is switched on, before the operating system. An attacker who can reach the machine with a crafted network message during such a network boot can hang the boot, or, with work tailored to the exact firmware build, run their own code before Secure Boot and other startup defenses load. An attacker needs no password and no existing access to the machine, but does need to reach it over the network during the short window when it is booting this way. Red Hat and SUSE, which both ship the affected code, rated the flaw as one an attacker exploits from an adjacent network position rather than across the open internet. TianoCore, the project behind EDK II,  published an advi...

Adobe has released patches to address multiple critical security flaws in Campaign Classic that, if successfully exploited, could result in arbitrary code execution, security feature bypass, and privilege escalation. The list of eight vulnerabilities is as follows - CVE-2026-104351 (CVSS score: 9.9) - A code injection vulnerability that could lead to arbitrary code execution. CVE-2026-104353 (CVSS score: 9.9) - An operating system code injection vulnerability that could lead to arbitrary code execution. CVE-2026-105780 (CVSS score: 9.9) - An incorrect authorization vulnerability that could lead to arbitrary code execution. CVE-2026-105489 (CVSS score: 9.9) - An SQL injection vulnerability that could lead to security feature bypass. CVE-2026-105781 (CVSS score: 9.8) - An SQL injection vulnerability that could lead to security feature bypass. CVE-2026-104350 (CVSS score: 9.3) - A reflected cross-site scripting vulnerability that could lead to privilege escalation....

An unreleased Anthropic AI model found security flaws in Chrome, Safari, Android, Windows, and Linux and chained them into working proof-of-concept exploits, the company said in its latest report. The exploits were built in the lab after the model was prompted, not seen in any real attack, and Anthropic reported every flaw to the vendor first, so all of them are already patched. One proof of concept opened the Calculator app on a stock Mac running Chrome within seconds of a page loading, with no further clicks. Anthropic's Frontier Red Team described five chains in a research post. The strongest claim is not any single bug, but that one model found several separate flaws and combined them into a working exploit, something the company says has until now been the work of a few specialist teams. That capability claim rests on Anthropic's own account. The patches and the fact that Apple and Google credit Anthropic and its Claude model for specific fixes can be verified with...

Tailscale has released  version 1.104.4  to fix flaws in its built-in SSH server that could let an attacker reach services and files on other servers that only the root user should be able to touch. The flaws are in how Tailscale SSH forwards network connections, a job the Tailscale background process carries out with root privileges. To use them, an attacker must already control a device that the network's access rules permit to open an SSH session to the target, with forwarding allowed in that rule. The flaws come from a report called  Tailworm , published days before the fix by Erica Windisch of Cyberdione Labs, who tested released versions of the Tailscale client and the self-hosted headscale control server in a lab. Tailscale SSH decides who can connect using a device's identity and the network's policy file, not a password or key, so an attacker does not need stolen credentials, only a foothold on a device the policy already trusts. The ...

The critical Oracle PeopleSoft bug that ShinyHunters has exploited since May is not one flaw but three chained together, the researchers who reported it said this week. Oracle patched all three under a single identifier,  CVE-2026-35273 , in June. Its root is a server-side request forgery (SSRF) that reaches an internal management interface because PeopleSoft trusts its own loopback address by default, opening the door to remote code execution without a login. The breakdown comes from Bobby Gould of the Zero Day Initiative (ZDI), whose team reported the flaw to Oracle. In  its analysis , ZDI said it reported three distinct vulnerabilities across two PeopleSoft components, and that it is working with Oracle to assign a separate CVE to each. As of this week, the one June identifier is still the only one on the record. CVE-2026-35273 affects PeopleSoft Enterprise PeopleTools versions 8.61 and 8.62, carries a CVSS score of 9.8, and lets an unauthenticated attacker take o...

The U.S. Cybersecurity and Infrastructure Security Agency (CISA) on Tuesday added two vulnerabilities impacting Adobe Commerce and Magento, and Google's Brotli decoder library to its Known Exploited Vulnerabilities ( KEV ) catalog, citing evidence of active exploitation. The vulnerabilities are listed below - CVE-2026-111497 (CVSS score: 9.2) - An unchecked return value vulnerability in Google Brotli that could allow a remote unauthenticated attacker to corrupt adjacent decoder state memory, disclose sensitive memory contents, cause a denial-of-service, or potentially execute arbitrary code using a crafted Brotli-compressed stream. CVE-2026-48356 (CVSS score: 9.3) - An unrestricted upload of a file with dangerous type vulnerability in Adobe Commerce and Magento that could result in arbitrary code execution in the context of the current user, potentially gaining elevated access or control over the victim's account or session. The development comes days after Sans...

Cybersecurity researchers have disclosed details of three cyber attacks targeting organizations in Japan in which artificial intelligence (AI) was a key element, either in the driving seat or to assist a human operator. TrendAI, which analyzed three exposed server environments used by threat actors to conduct the malicious cyber operations, described them as distinct from previously published attacks that have leveraged ARTEX , an autonomous AI penetration testing framework, to single out entities in South Korea and Japan. "These environments held reconnaissance and attack tools, scripts, target lists, results, logs, and command histories," security researchers Bakuei Matsukawa and Joseph C Chen said. "They ranged from workspaces used largely by hand by skilled operators to AI-agent platforms that automated the entire workflow, including command and control." The first of the three attacks has been found to abuse CyberStrikeAI , another open-source penetra...
