A new flaw in the Linux kernel's KVM virtualization code for ARM64 processors can leave a freed piece of host memory exposed to a guest virtual machine on hosts with nested virtualization enabled. The bug, tracked as CVE-2026-89775, allows a guest to read and write host kernel memory, and the researcher who found it says it can be used to escape the guest and run code on the host machine.

Malware already running on a Mac can quietly take over Meta's Muse assistant and use the broad access its owner granted the app, security researcher Patrick Wardle has shown in a proof-of-concept released on September 21. It works by changing a hidden setting so that when the user taps the microphone and dictates a prompt, the words go to the attacker instead of Meta. The flaw is in
Three researchers at the security firm Hacktron used Anthropic's Claude Opus 5 to chain two flaws and take over the ChatGPT and Codex accounts of several OpenAI employees, then reach an internal OpenAI code repository. The chain began with a bug in the software that runs OpenAI's public help forum and moved through a weakness in OpenAI's own login system. This was security research,

When the Digital Operational Resilience Act (DORA) became enforceable across the European Union in January 2025, it triggered an administrative sprint. Financial entities spent the first year establishing risk governance, assessing third-party service providers, updating contract clauses, and documenting incident escalation workflows. Now in its second year, the harder part of DORA is

Cisco Talos researchers created a new framework for identifying malware and hacking tools that rely on AI chatbots—and quickly discovered something unusual.
A malicious npm package named "indexed-btree" has been observed hiding its malicious behavior within application code rather than using lifecycle scripts, indicating that threat actors are likely shifting tactics in response to recent security controls. "Indexed-btree is a malicious npm package mimicking the legit sorted-btree package, an ordinary B-tree/indexing utility," Checkmarx said. "

AI Governance Engineer: an open body of knowledge mapping EU AI Act, ISO 42001 and NIST AI RMF to the artefacts that satisfy each obligation
What it is: a free, open, versioned body of knowledge on AI governance engineering: eleven chapters, a five-level maturity model, seventeen reusable patterns, and a crosswalk that maps each obligation to the concrete artefact that satisfies or supports it. CC BY 4.0, source on GitHub, versioned releases with a changelog and a DOI so it can be cited. Nothing to sign up for and nothing behind a paywall. Why I wrote it: frameworks tell you what must be true, and very little tells you what has to exist in the build for it to be true. Framework coverage proves you read the framework, not that any risk fell. So the crosswalk runs the other way — from the obligation to the artefact, and to the layer that owns it. The reference material is exported as data, not only as web pages: \- crosswalk (CSV and JSON): one governance topic per row, across the instruments that bind it \- obligations (CSV and JSON): obligation, artefact, owning layer \- glossary (JSON), cross-referenced to the chapter that defines each term [https://aigovernanceengineer.com/](https://aigovernanceengineer.com/) Two things I would like this sub to push back on: \- The mappings are my reading, and readings differ. If a row looks wrong, tell me which one and why, or send a pull request. \- I argue that continuous, machine-readable evidence beats a point-in-time attestation. If you have sat on either side of an audit or a certification, does that hold in practice, or do assessors still want the static pack? Wrong mappings are the thing I most want caught before anyone relies on them.
Your conversations with AI chatbots are both highly personal and deeply vulnerable to surveillance. Here’s how you can protect yourself.

Hey everyone, I’m black-210, the main developer of VULTURE. I started VULTURE around RF and SDR analysis, but over time it became much bigger than that. I wanted to build a platform where RF/signal processing, scientific computing, machine learning, digital forensics, chemistry, physics, mathematics, visualization, and research workflows could exist together instead of having each part live as a completely separate project. So VULTURE is now a modular intelligence and research platform, with Python APIs, a CLI, an optional PyQt6 GUI, analysis frameworks, reproducible/offline workflows, reporting and provenance, and a separate native C layer. What VULTURE actually covers RF / SDR / IQ FFT and FFT-engine workflows PSD analysis spectrograms and waterfall visualization signal detection peak and burst detection occupancy analysis noise-floor analysis interference and anomaly analysis IQ loading and handling IQ recording and playback workflows metadata and calibration boundaries resampling and signal-processing utilities receive-oriented SDR integration boundaries RTL-SDR / PlutoSDR / UHD-USRP / SoapySDR compatibility boundaries where the required drivers are available RF-DNA and RF fingerprinting capture comparison and fingerprint reports Scientific computing RF wavelength calculations free-space path-loss calculations physics calculations mathematics utilities spectroscopy-related calculations NMR / Larmor-frequency calculations material and electromagnetic-property screening complex-permittivity calculations deterministic simulation profiles numerical and statistical analysis AI / ML / analytics VULTURE also has an AI/ML side rather than treating machine learning as an afterthought. It includes areas for: feature engineering preprocessing model evaluation classical machine-learning workflows optional deep-learning components optional ONNX-related workflows clustering anomaly detection statistical analysis time-series analytics model/feature pipelines explainable feature reports offline benchmarking human review of analytical results The goal is to make ML another analysis layer that can work with the scientific and signal-processing parts of the platform. Forensics / evidence / auditing There is also a forensic layer for working with supplied data and evidence metadata. It includes: physics audits chemistry audits mathematics audits protocol/frame audits structured JSON reports human-readable reports SHA-256 capture/file hashes provenance metadata case IDs and sample IDs authorization metadata bounded inputs fail-closed validation audit/review fields reproducible analysis information The forensic side is intended to make analytical results easier to review and reproduce rather than pretending that a software output automatically proves attribution or identity. Chemistry / physics / materials The Chemical-RF side is another part of the project. For example, VULTURE can work with: NMR/Larmor calculations spectroscopy-related workflows RF/material screening complex permittivity conductivity-related calculations electromagnetic material calculations resonance-related calculations combined physics/RF calculations These are primarily local scientific calculations and research tools, not replacements for physical laboratory measurements. Visualization and GUI VULTURE can run completely from the terminal, but it also has an optional PyQt6 interface. The GUI provides surfaces for things such as: RF intelligence SDR/IQ workflows machine-learning workflows RF-DNA/fingerprint review provenance review visualization analysis results The GUI is optional, so the core platform can still be used headlessly. Quantum / research experiments There is also an experimental research layer. Some of the work includes: QFT-style versus classical FFT comparisons quantum-inspired experiments small variational/research experiments simulated noise and robustness experiments reproducible seeds classical baselines for comparison scientific experimentation that does not require quantum hardware This is experimental research functionality, not a requirement for normal VULTURE usage. VULTURE C One part I don't want to leave out is the C extension layer. Inside the same repository there is a separate c/ directory containing VULTURE C, a native C11 layer designed to complement the Python platform. It is intentionally independent and can be compiled separately. The C layer currently includes things such as: signal statistics mean / variance / standard deviation RMS median range peak-to-peak measurements local peak detection statistical thresholds SHA-256 hashing of files and memory buffers RF wavelength calculations free-space path-loss calculations deterministic command-line analysis JSON-like/offline reporting a text-to-C tool translator reusable C APIs standalone C analysis engines strict C11 compilation explicit memory ownership fail-closed error handling dependency-light native utilities For example, the C layer contains separate native programs for general analysis, RF analysis, hashing, and the tool translator. It can be built independently with: make -C c I wanted this layer because some parts of the platform make sense as small deterministic native components rather than everything being implemented in Python. So the repository isn't just a Python RF script with a C file added somewhere. The C directory is intended to be a real native extension layer with its own API, tools, build system and documentation. Reproducibility and security model A major design goal of VULTURE is that analysis should be reviewable and reproducible. The platform includes things such as: deterministic offline fixtures reproducible seeds capture/file hashing provenance metadata structured reports explicit case/sample identifiers bounded inputs validation controlled hardware boundaries operator-review fields fail-closed behavior The receive-side hardware integrations are intentionally separated from the offline analysis workflows. VULTURE is receive/analyze-only by design. It does not provide jamming, spoofing, unauthorized interception, credential theft, exploitation, evasion, or automatic RF transmission. It is intended for systems, frequencies, receivers and datasets that the operator owns or is explicitly authorized to analyze. Linux distribution support Another thing I'm genuinely proud of is that VULTURE has moved beyond just being a repository on my GitHub. It is currently packaged in BlackArch as: vulture-black BlackArch's official repository: https://github.com/BlackArch/blackarch BlackArch is an Arch Linux-based distribution for penetration testers and security researchers, and its repository contains thousands of security tools. VULTURE has also been added to the Pentoo overlay as: net-wireless/vulture Pentoo's official overlay: https://github.com/pentoo/pentoo-overlay Pentoo describes this repository as its Gentoo security-tools overlay and the heart of the Pentoo LiveCD. Getting VULTURE packaged by security-focused Linux projects was honestly one of the coolest milestones for me. It means the project can exist in real security-oriented Linux ecosystems rather than only being something people clone directly from my repository. Where the project is GitHub: https://github.com/black-210/VULTURE Codeberg backup: https://codeberg.org/black-210/VULTURE I'm keeping the Codeberg repository as an independent backup as well. I'm still actively developing VULTURE, and there is a lot I want to improve. Some parts are mature, some are experimental, and some are still being expanded. I'm sharing it here because I'd genuinely like feedback from people working in defensive security, digital forensics, RF/SDR, signal processing, machine learning, scientific computing, or open-source research. If you were working on a platform like this, what would you add next? Are there analysis workflows, forensic capabilities, ML features, RF features, or research tooling that you think would be particularly useful? Thanks for taking a look. — black-210

We introduced Python Workers two years ago, providing a way to run Python applications in the Cloudflare Workers runtime. Our goal was to make it as simple to write Workers in Python as it is in TypeScript, and to make the ecosystem of Python packages and frameworks “just work”. Today, Python Workers are now generally available (GA). What does GA mean? It means Python is now a first-class, fully supported language on the Cloudflare Developer Platform. You can bring the Python code, libraries, and design patterns you already know and connect them seamlessly to Workers AI, R2, D1, Hyperdrive, Durable Objects, Queues, Workflows, and the rest of the Cloudflare platform. You can also run popular Python frameworks like FastAPI, Django, and Flask inside Python Workers. You can even create a Python Worker inside another Worker using Dynamic Workers . The journey behind Python Workers Bringing Python to Cloudflare Workers was a natural choice. Because Workers has supported WebAssembly since 2018 , it gave us the perfect environment to run a Wasm-compiled Python interpreter. By using Pyodide , we were able to quickly support a wide range of Python applications in Cloudflare Workers. Our goal was to create the first platform for infinitely scalable Python apps, while making it as easy and performant as developing Python apps anywhere else. The features we are highlighting today are the result of this multi-year effort. Many developers are already building applications within Python Workers
Born out of academia and raised in corporate IT departments, the Security Assertion Markup Language (SAML) authentication protocol continues to be a staple in these organizations. However, it’s time for it to retire. With the rise of software-as-a-service (SaaS) companies in the late aughts, IT departments needed a way for users to authenticate to many new web services. SAML and the burgeoning single sign-on (SSO) industry fulfilled this need. However, SAML is being crushed under the weight of its own complexity. It’s time to deprecate it and move on to modern alternatives like OpenID Connect (OIDC). In this post, I will explore the design-by-committee origin of SAML, its progression through the ranks in academic and corporate environments, its slow disintegration at the hands of the security research community, and its (hopeful) deprecation in favor of newer protocols. SAML 101 What’s insidious about SAML is that it really is mostly straightforward to understand, but it’s built on a foundation of sand, bone dust, and ash; it works … if you assume XML signature validation is reliable. But XML signature validation is deeply cursed, and is so complicated that most fielded SAML implementations are wrapping libxmlsec, a gnarly C codebase nobody reads. — Thomas Ptacek, 2023 SAML and the birth of the SSO industry Wikipedia tells me that “SAML is an

Author here. The post describes three memory-safety bugs which have been in Godot since v1.0 and v3.0. All three are still present in current releases. The bugs can affect exported games that load community-authored data files. Godot allows attackers using maliciously crafted files to trigger reads or writes past the end of a buffer, inside the process running the game. The post includes the response from Godot maintainers who deny this is a security issue, and my reply to them. Happy to give more information about the bugs or the audit if there are questions.

This short blog post is about abusing a privilege escalation bug that Microsoft recently fixed in Windows, CVE-2026-66804, that I and 14 others reported. This issue is an incomplete fix for CVE-2026-50343, a bug dubbed “Dark Elevator” by Calif. The root cause of the bug was a dangling COM object registration for the CrossDevice COM object with the CLSID {E9F83CF2-E0C0-4CA7-AF01-E90C70BEF496}. A COM registration typically needs two parts: a server executable, which for in-process components is a DLL and a CLSID entry under the HKEY_CLASSES_ROOT registry key which points to that DLL.

Cloudflare operates at a scale so big that even after working here for years, it doesn’t seem real. We have thousands of servers all over the world with petabytes of RAM and millions of CPU cores, and all of it is pushed to the max. As vast as those resources feel, they are still finite, and when you need every service to run on every node, it doesn’t leave room for wasted space. At this scale, small improvements are greatly magnified, so even 1%-at-a-time improvements are worth celebrating. And some tweaks add up to a lot more: in this post, we’ll look at how small changes to a single algorithm reduced the memory footprint of one of our Pingora-based services significantly. That allowed us to reclaim more than 100TB of RAM globally, on top of the 100TB of memory the DNS team was able to shed last month . Waste not Maintaining equitable resource sharing between teams is not easy, especially in large organizations. One of the ways Cloudflare ensures the balance is kept is through the tireless efforts of the wonderful Performance team. This story starts with a ticket filed by Ivan who found: Excessive memory usage from pingora-ketama in Pingora Backend Router . The finding was that our internal load-balancing service, Pingora Backend Router (yes, PBR), was using significantly more memory than expected — specifically in structures associated with pingora-ketama, which is our open-source library for handling consistent hashing. In order to talk about ho

Security firms have published numerous blog posts describing how they pointed their agent harness at a codebase and found dozens of bugs ( we’re one of them ). However, these posts tend to focus on agentic code review, which is just one aspect of how we use AI in our security reviews. We want to give a different perspective: before code review even starts, agents now allow us to build custom tooling and formal models that improve the quality and depth of our reviews. We recently reviewed the Miden VM, a new zero-knowledge VM with its own custom assembly language and almost no developer tooling. To prepare, we spent six months having our agents build an LSP server , a decompiler , a static analysis engine , and a Lean model of the VM executor from scratch. These tools found real security issues, like an unvalidated prover-supplied input that would let a malicious prover forge Falcon signatures and steal funds from Miden account holders. Additionally, the Lean work produced 95 machine-checked correctness proofs, covering a large component of the Miden core library. Auditing the Miden zkVM In late 2025, the Miden team came to us to have parts of their zero-knowledge VM reviewed before launch. Part of the review was scoped to cover the Miden core library, which contains a small set of cryptographic primitives written in a custom assembly language called Miden as

Overview Dokploy versions 0.29.8 and 0.29.11, as well as commit 24b02f5 on the canary branch, are vulnerable to OS command injection during the backup creation and restoration processes. The vulnerability stems from unsanitized shell command construction that can allow an attacker to escalate privileges and lead to full compromise of the target device. Description Dokploy is an open-source Platform as a Service solution for deploying applications and databases on self-hosted servers. Dokploy allows authenticated users to create and schedule database backups and restore previously created backups. These backup operations are executed by the Dokploy process, which runs with root privileges by default. Dokploy is vulnerable to OS command injection in its database backup creation and restoration functionality due to insufficient sanitization of user-controlled input before it is incorporated into shell commands. The vulnerable backup functionality constructs database-specific shell commands that directly interpolate a user-supplied database name, while the restore functionality incorporates a user-supplied backupFile value into a shell command. Both operations ultimately pass the resulting command to a shell execution helper that invokes /bin/bash as a child of the Dokploy process, without shell escaping or restrictions on shell metacharacters. The affected parameters are exposed through tRPC procedures that only validate that the supplied values are non-empty strings. Consequently, authenticated users with permission to perform database backups can supply shell metacharacters that are interpreted by /bin/bash , resulting in arbitrary command execution on the Dokploy host with the root privileges of the Dokploy se

How Brutus grew into an engine that finds your identities, tests them everywhere they’re accepted, and remembers what it confirms. An attacker rarely needs a novel exploit when a valid username and password pair is sitting in a breach dump, reused across a dozen internal services, or left at a vendor default nobody changed. Brutus started as a focused credential testing tool. It has since grown into something broader: an engine that finds the identities attached to an organization, tests them everywhere they might be accepted, and carries what it confirms forward into future runs. All of it runs automatically as part of the pipeline. There’s no manual setup and no analyst kicking off individual checks. Here’s what changed. Knowing who works there Testing a credential assumes you already know the account exists. Brutus now builds that picture from more places. A new people enumeration subsystem maps organizational exposure using professional identity data, drawing on an Apollo.io connector built with a split discover and enrich flow so the full org roster isn’t revealed automatically. A LinkedIn Sales Navigator connector adds another path for personnel discovery. Microsoft 365 enumeration is now a first class command in its own right rather than something reachable only from inside another mode, and it supports rotating proxies. GitHub email enumeration through rotating proxies is also fixed: the CSRF session handshake no longer stalls or fails quietly, and progress is visible while the session is being established. Two smaller changes make the output easier to work with. Generated usernames now carry the first and last name that produced each candidate, so nothing downstream has to reverse engineer a person’s name from the loca

A modern storefront can look perfectly healthy while malicious JavaScript works underneath: siphoning affiliate revenue, hijacking searches and clicks, tampering with analytics, or asking a remote server what to execute next. Pages load, products appear, and checkout works — yet the browser may be quietly doing something the site owner never authorized. That is the blind spot our Client-Side Security machine learning (ML) model is built to expose. This post follows four operations, spanning eight payloads, that our Page Shield ML uncovered in the wild. The detection of these malicious payloads was automated; humans verified each finding only after the system had flagged it. When we afterward reviewed the campaigns using security scanning tools, seven of the eight payloads were entirely absent from VirusTotal, and URLScan returned no malicious verdict for any of them. Page Shield ML , meanwhile, caught all eight in live traffic. For instance, while security research documented the broader Lnkr family years earlier, one specific payload version sat indexed by URLScan for nearly two and a half years with “No classification,” including during a direct scan in January 2024. Only in this case had VirusTotal ingested the payload earlier: while it currently flags the script as malicious, public history does not reveal when that verdict was first assigned. Meanwhile, Page Shield ML independently surfaced those exact bytes live on an online retailer's storefront. More broadly, a hash can be known long before the code behind it is classified as malicious. If your defense
The consumer data broker Radaris.com has long had a reputation for ignoring requests to remove personal information from its vast empire of people-search services online. That reputation caught up with the company recently in a lawsuit alleging Radaris violated a New Jersey privacy law that provides for hefty fines against data brokers that publish personal information on state law enforcement officials. In the face of repeated stonewalling and prevarication by attorneys for Radaris, the judge in the case ordered that radaris.com and more than a dozen other data broker domains be transferred to the plaintiffs.

Overview A vulnerability in MLflow’s dspy and statsmodels model flavors allows unauthorized pickle deserialization executions despite a safety control. Specifically, the dspy flavor conditionally applies the control based on the model path’s file extension, and the statsmodels flavor does not apply the control. Description MLflow is an open-source platform for managing machine learning lifecycles, including model packaging, versioning, and deployment. "Flavors" refer to the specialized frameworks through which supported models are stored and loaded. In response to previous vulnerability concerns, MLflow implemented the MLFLOW_ALLOW_PICKLE_DESERIALIZATION safety control to block and disable executing any pickle deserialization and subsequent loads per the user’s choice. When loading models through mlflow.pyfunc.load_model(model) , users must specify a model flavor and path in an MLmodel file. With the dspy flavor, MLflow checks the value of MLFLOW_ALLOW_PICKLE_DESERIALIZATION , and whether the specified model path ends in .pkl . A model path that does not end in .pkl (even if the file is actually a pickle file), will route to a separate branch for pickle deserialization, bypassing the safety control. However, when loading through the statsmodels flavor, there is no check for MLFLOW_ALLOW_PICKLE_DESERIALIZATION at all. Impact Exploitation of this vulnerability allows for arbitrary remote code execution through a malicious pickle-loaded payload, regardless of a user explicitly disallowing pickle serialization, through vulnerable flavor specifications in the MLmodel configuration file. The attack path requires write access to any location from which a use
VU#212479: Sentry Seer vulnerability allows attacker-controlled input to be executed in a privileged environment
Overview A vulnerability exists in Sentry Seer when the system is configured to automatically hand issues to a coding agent for remediation. Successful exploitation results in arbitrary code execution within the coding‑agent environment and access to connected source repositories. This vulnerability is tracked as CVE-2026-90999 . Description Sentry is a software error‑monitoring and performance‑tracking platform used by developers to detect, diagnose, and understand issues in their applications. It collects telemetry such as exceptions, stack traces, logs, and performance data from applications. Built into Sentry, Seer acts as an automated debugging assistant that converts telemetry into actionable remediation steps and can hand off issues to an integrated coding agent to propose code fixes. Because Sentry front-end projects commonly expose a public DSN (Data Source Name) to allow browsers to submit this telemetry, an attacker can craft and submit malicious events through this public endpoint. When Seer is enabled to automatically pass issues to a coding agent, these attacker-supplied events can traverse multiple trust boundaries. Ultimately, malicious event fields propagate through Seer’s analysis pipeline, transforming into untrusted instructions that the privileged coding agent may execute. The vulnerable workflow is as follows: * Sentry ingests attacker‑generated exception events submitted through the public DSN. * Seer evaluates whether the event represents an issue eligible for automated remediation. * Seer generates a root‑cause analysis that uses attacker-controlled event fields, including exception messages, stack traces, source context, and breadcrumbs. * The generated analysis is embedded directly into the initial prompt provided to the coding agent.

Third-party penetration testing means two different things: testing your own organization through an independent provider, and testing or reviewing testing on a supplier, partner, or acquisition target. This guide focuses on the second use case. It works best as a governed risk process, not a document request, built on clear authorization, risk-based scope, defensible evidence, and contractual follow-up. The post Third-Party Penetration Testing: What Security and Procurement Teams Need to Know appeared first on Synack .
Without proper controls, website owners have long faced a difficult tradeoff: allow your content to be used for AI training, or risk losing discoverability in search. That tradeoff exists because some of the largest organizations on the Internet use mixed-use crawlers: a single crawler serving both search and AI training. Refuse one, and you refuse the other. Today, Cloudflare is announcing a new Disallow AI Training setting that lets you easily stay indexed for search while refusing to let that same crawler train on your content. Apple, Google, and Microsoft honor or have committed (in a specified time frame) to honor this setting. Mixed-use crawlers were the hard part of the training question. AI Summaries are next. A site-wide yes or no is too blunt: how much of your content appears in a summary matters as much as whether it appears at all. An opt-out for AI summaries is already one of the requirements we've set for mixed-use crawler operators. By early next year, our goal is to let you control how much of your content is included — set once on Cloudflare, rather than with each operator separately. Why asking isn’t enough Most site owners want to be found: by humans, agents, and (good) bots. But a significant portion of the open Internet is funded by advertising, subscriptions, or direct relationships with visitors, and those models only pay when someone actually arrives. Almost every site owner considers Search beneficial: less than 1% of Cloudflare sites choose to block Search bots. Training, however, is a different story: 17% of sites choose to enable some mechanism to block training. This is exactly why we decided site owners needed more granular controls, rather than a one-size-fits-all “Block AI.” A robots.txt directive alone cannot solve this problem. Anyone can publish one, but it cannot identify who i
As more teams — and now agents — build applications on Cloudflare's Developer Platform, having the right access controls is crucial to allow you to ship safely. After all, the last thing you want is for an agent to make a change in production, just because it was granted more access than it needs. Now, you can give a teammate or agent access to a specific Worker, so that they can only make changes to that application and no other resources in your account. Moreover, we’re giving you four new roles, so you can limit exactly what they can do: The new roles are available today, for all customers. You can assign them to a specific user, so when they log into the dashboard, they will only see the Worker you have given them access to. Or, you can create an API token with the scoped access, which you can give to your agent to ensure they only have access to that one application. Here’s an example of how to create an API token with permissions per Worker: Roles designed for how teams build When defining these roles, we wanted to strike the right balance. Overly broad roles force you to grant more access than intended, undermining the principle of least privilege, while providing too many individual permissions makes it difficult to know which ones to grant. We landed on four roles that reflect the levels of access you may want to give a person or agent: enough to debug a resource without exposing its content, read the content without changing it, make changes without being able to delete the resource, or fully manage it. We plan to use these same roles as we bring resource-level access controls to other Developer Platform products, including D1, R2, and KV. Each role can be applied at one of three scopes. For example, if you set the “metadata read-only” control, here’s what that would look like at different levels: Developer Platform level: Access
