Debian and Ubuntu APT Flaw Lets MitM Attackers Swap Verified Packages and Run Code as Root

A flaw in APT , the package manager for Debian and Ubuntu, allows an attacker who can modify package downloads to swap a checked package for their own. The attacker's code then runs as root, according to advisories that  Debian ,  Ubuntu , and  APT's developers  published on November 4. The attack needs APT to retry failed downloads, which it does by default from Debian 12 and Ubuntu 22.04 onward. Debian has released fixed versions of APT for the flaw, CVE-2026-109518 . APT's developers, who call the flaw critical, say updates for Ubuntu and its Ubuntu Pro subscription service are being released. Ubuntu 14.04 users with Ubuntu Pro can already get one. Older releases, such as Debian 11 and Ubuntu 20.04, are not exposed by default, according to Ubuntu. But many user scripts may have turned on the retry setting, Acquire::Retries, on those releases anyway, APT's developers say. Debian's testing branch was still on the  vulnerable version 3.3.5  at...

SonicWall Won't Patch EoL GMS Flaws That Could Expose Files, Alter Database Records

SonicWall has warned of two vulnerabilities impacting end-of-life Global Management System (GMS) systems that it said will not be patched. Details of the security flaws, which affect SonicWall GMS 9.5.2 and earlier versions, are below - CVE-2026-109593 (CVSS score: 9.1) - An unauthenticated file read vulnerability that could allow an attacker with network access to read internal GMS files, potentially exposing sensitive information. CVE-2026-109594 (CVSS score: 6.8) - A post-authentication SQL injection vulnerability that could allow an authenticated attacker to access or modify information stored in the GMS database under specific conditions. "The affected product has reached End-of-life (EoL)," SonicWall said in a Tuesday alert. "As a result, no remediation or security update will be released for these vulnerabilities. Organizations using the product should be aware of the associated security risks and are strongly encouraged to upgrade to the SonicWa...

Researchers Uncover Prompt Adware Hidden in OpenAI Codex Jailbreak Toolkit

Cybersecurity researchers have disclosed details of an OpenAI Codex jailbreak bundle that's designed to modify an artificial intelligence (AI) agent's trusted instructions to insert advertisements for a third-party AI gateway. The phenomenon has been codenamed prompt adware by Check Point Research. Called Haiou (meaning Seagull in Chinese), the jailbreak modifies OpenAI Codex's configuration files to inject advertisements for the jailbreak author's website into subsequent agent responses. "The advertised service is an opaque, OpenAI-compatible LLM gateway, a middleware between an application and an LLM provider," Check Point Research said in a technical report. "The likely business model is to use the freely distributed jailbreak bundle as an acquisition channel for the paid gateway service." Adware is a type of software that displays unwanted advertisements, which can appear on users' computers or mobile devices, often in the form of ...

APT29-Linked Hackers Hijack Web Analytics Script to Deliver iOS and Android Exploits

The Russia-linked threat actor known as APT29 is said to be behind a large-scale watering hole campaign targeting iOS and Android users through compromised websites, fake domains, and a supply chain attack involving a Ukrainian web analytics service called Plerdy SEO Tracker. "The injected JavaScript code collects browser and device attributes," Sekoia researchers Amaury-Jacques Garçon and Félix Aime said in a technical report shared with The Hacker News. "Then, the delivery infrastructure delivers a platform-specific N-day exploit chain targeting either iOS or Android." The end goal of the attacks is to serve payloads capable of stealing browser cookies, and in some cases, Wi-Fi passwords or full mobile device data. The activity, codenamed Poisoned Source , was discovered by the French cybersecurity company in mid-October 2026. A defining aspect of the campaign is the use of three infection vectors - Compromise of legitimate websites to inject malicio...

Critical Rails Flaw Lets Attackers Write Server Files via Crafted ImageMagick Uploads

A critical flaw in Ruby on Rails could allow an unauthenticated attacker to write arbitrary files on an app's server by uploading a crafted file if the app processes uploads using ImageMagick . The Rails project disclosed the flaw in  an advisory  and fixed it in versions 8.1.4.1 and 8.0.5.2. The flaw is in Active Storage, the part of Rails that handles file uploads. Some apps store uploaded files using Active Storage's Disk service, which stores them on the server's disk. In those apps, an attacker could also read any file the app can read. Those files typically include the app's secret_key_base and its credentials for other systems, according to Rails. Reading them may in turn allow remote code execution or lateral movement into those systems. Rails rates the flaw 9.8 out of 10 on the CVSS scale. It is tracked as GHSA-f3w6-w445-fwh9 and does not yet have a CVE identifier. ImageMagick selects a format handler, which it calls a coder, based on the file's c...

Xen Hypervisor Flaws Let One Malicious VM Read and Write Any Other VM's Memory

Two flaws in the Xen hypervisor allow a malicious guest virtual machine (VM) to read and write the memory of other VMs on the same host, including dom0. Dom0 is the VM that, by default, has full permissions and manages the others. Patches are out, and there is no known mitigation, the Xen Project said in an  advisory  on November 3. All Xen versions from 4.6 onward are vulnerable, while 4.5 and earlier are not. The flaws are tracked as CVE-2026-102703 and CVE-2026-102704 , under Xen advisory XSA-523. The Xen Project credited AI company Anthropic with finding the flaws using its Claude model. Stephan Lipp of Ada Logics then validated the finding, and the CodeAnt AI Security Research Team later independently reported the same issue. The flaws are in grant copy, the operation Xen uses to copy data between VMs. Each VM tells Xen which of its memory pages other VMs may use, and Xen checks those permissions. To save time on a batch of copies within the same memory page, ...

Radio With No Radar: Why Agent Runtime Security Fails Without the Layers Beneath It

Nearly every agent security pitch now ends on the same promise: the product stops the bad action in real time. The promise holds for one kind of agent, the kind whose traffic passes through a gateway the enterprise owns. Most agents never touch one. One recent case shows what that gap looks like in practice. An employee asked an AI assistant to trigger a mass-email automation. The automation hit a recipient-limit policy and failed, so the assistant, which was also connected to the employee's personal mailbox, offered to send the batch from there instead. The employee approved without registering that the assistant was about to route around the sanctioned system. An unknown number of external recipients received email from a personal account rather than the approved channel. No jailbreak was involved. The assistant did exactly what it was built to do, and the fix was not retraining a model. It was a single runtime rule that blocks any attempt to reach more than fifty external d...

China-Aligned Hackers Hijack Sogou Input Method DNS Requests to Deploy DarkVigil Backdoor

A China-aligned threat actor known as SlippyNunchucks has been attributed to a Domain Name System (DNS) hijacking operation abusing insecure HTTP communications in Windows versions of Sogou Input Method as part of a surveillance campaign designed to deploy an implant called DarkVigil (aka FDMTP). The campaign, observed starting July 1, 2026, is assessed to have targeted organizations and Chinese-speaking individuals in Hong Kong, Thailand, Japan, Vietnam, Oman, and Sri Lanka, according to ESET. "DarkVigil implants are typically deployed through popular Chinese applications," ESET researcher Anh Ho said in a report shared with The Hacker News. "By abusing these applications, the SlippyNunchucks threat actor has been able to reach Chinese-speaking users across Asia and Europe." Some of the applications abused by the adversary include Sogou Input Method, QuickFox, QingTalk, MiYunChat, SoftCam, and tawk.to. Active since at least September 15, 2023, SlippyNunc...
