Hey everyone, John Strand here. I’m teaching Information Security Core Skills live starting May 11th at 12:00 PM EDT. This is a 16-hour, hands-on class for people who are new to security, or folks who want the fundamentals explained in a way that actually connects to real work. At Black Hills Information Security, we see a lot of the same issues show up across assessments. This class is built around those patterns: practical attacks, practical defenses, and the core controls that matter. We’ll also cover how to use AI in a practical way. Not as a replacement for learning the fundamentals, but as a tool to help you move faster, ask better questions, and understand what you’re working on. Live training is pay-what-you-can: $25 to $300. If you’re trying to build a real foundation in security, this is the class I’d point you to. Thanks! strandjs

We are Alex and Armaan, insider risk researchers on the DTEX i3 team. We spend most of our time analyzing how new technologies introduce risk inside corporate environments, especially when they operate with legitimate access and little visibility. Recently, our work has focused on agentic AI on endpoints. These are autonomous or semi-autonomous AI agents that run locally on user devices, execute commands, access files, and interact with external services, often without continuous human input. This research is covered in DTEX’s latest [i3 Threat Advisory: Detecting Agentic AI on Endpoints Before Data Exfiltration,](https://www.dtex.ai/resources/i%C2%B3-threat-advisory-detecting-agentic-ai-on-endpoints-before-data-exfiltration/?utm_medium=ama&utm_source=reddit&utm_campaign=AI&utm_content=reddit-ama&utm_keyword=) where we break down how these agents are deployed, how they behave, and how they can quietly introduce insider risk. We mapped real endpoint indicators tied to agent setup, persistence, and activity, including things like containerized AI agents, credential exposure in process parameters, message-driven execution via apps like Telegram, and patterns that signal potential data exfiltration. The key challenge is that this doesn’t look like traditional threats. There’s no malware, no exploit. Just legitimate access, automation, and a lack of visibility. We are here to answer questions about: * how agentic AI operates on endpoints in real environments * what makes AI agents an insider risk (even without malicious intent) * how these tools create new paths for data exfiltration and credential exposure * what behavioral and technical signals can reveal agent activity * where detection breaks down, even with modern security stacks * what organizations can realistically do today to reduce risk Ask us anything and [join our workshop](https://www.dtex.ai/events/ita-workshop-agentic-ai-moving-to-the-endpoint/?utm_medium=ama&utm_source=reddit&utm_campaign=AI&utm_content=reddit-ama&utm_keyword=) (hosted by the DTEX i3 team) on May 12 to dive deeper into the advisory.
A law firm instructed my first forensic analysis of an LLM system, I've written up some of my methodology
I have worked for about 10 years in cybersecurity, mostly in Incident Response, but I've done a fair bit of forensic work and expert witness cases within that. A year ago I left my old firm to go down the independent consultancy route, and still trying to figure out exactly what I'm doing. A couple months ago a law firm I used to work with reached out recently. Short story is that an LLM agent made a mistake for their client which became litigious. The client firm claimed they had addressed the original issue, but the law firm requested an expert opinion on: a) the root causes of the original issue b) an assessment on whether this could re-occur / validation of the fix This might not fall strictly within the confines of "computerforensics", so apologies if it's slightly off topic. But I figured there could be some practitioners here who might be interested in the methodology. I basically used three techniques to model the differences in generated output between the "bad" model and the fixed "good" model, then commented on the deviations. I don't think this is a huge market right now. But I do see that there are insurance companies starting to underwrite AI risk, so it's possible we could be seeing more of this work over the next few years. I've written up my full approach here: [https://www.analystengine.io/insights/how-to-forensically-analyse-llm-alignment-drift-and-hallucination](https://www.analystengine.io/insights/how-to-forensically-analyse-llm-alignment-drift-and-hallucination) Would be really interested to hear if anyone is doing any similar work lately.

VanGuard — open-source single-binary DFIR toolkit (Velociraptor, Hayabusa, Chainsaw, Loki, YARA) with TUI, air-gap support, and 28 pre-built use cases
We just open-sourced **VanGuard** — a self-contained IR toolkit that bundles Velociraptor, Hayabusa, Chainsaw, Loki, and YARA into a single binary with a terminal UI. Built it because we were tired of the 45-minute tooling setup at the start of every engagement. Download KAPE, remember the flags, set up Velociraptor, manually hash evidence, and track the chain of custody in a spreadsheet. What it does: * Quick triage (20+ Windows, 15+ Linux artifact categories using native commands) * Velociraptor server lifecycle + agent deployment from the TUI * Threat hunting with Hayabusa, Chainsaw, Loki, YARA + live anomaly detection * Memory capture + Volatility 3 analysis * 28 pre-built use cases (ransomware, BEC, credential theft, lateral movement, rootkits) with MITRE ATT&CK mapping * Evidence dual-hashed (MD5 + SHA256), HMAC chain of custody * Runs from USB, works fully offline Cross-platform (Windows + Linux), Apache 2.0, no dependencies.

For vulnerability research, smaller models run repeatedly can outperform larger frontier models on cost-to-recall.
TL;DR: If a large model finds a 0-day with 90% probability, and a small model with 50% probability, but the small model costs 10x less, it is better to use the small model. We compared the cost and recall of various models in finding real, recent zero-days and found that for most applications, smaller models run repeatedly can significantly outperform larger frontier models on cost-to-recall. Disclaimer: I'm involved with Hacktron, the company that produced this research. This is a factual presentation of our benchmarks, which we hope the community can use to make informed decisions about models like Mythos.
Over the past two and a bit quarters, we've undertaken an intensive engineering effort, internally code-named " Code Orange: Fail Small ", focused on making Cloudflare's infrastructure more resilient, secure, and reliable for every customer. Earlier this month, the Cloudflare team finished this work. While improving resiliency will never be a “job done” and will always be a top priority across our development lifecycle, we have now completed the work that would have avoided the November 18, 2025 and December 5, 2025 global outages. This work focused on several key areas: safer configuration changes, reducing the impact of failure, and revising our “break glass” procedures and incident management. We also introduced measures to prevent drift and regressions over time, and strengthened the way we communicate to our customers during an outage. Here we explain in depth what we shipped, and what it means for you. Safer configuration changes What it means for you : In most cases, Cloudflare internal configuration changes no longer reach our network instantly and are instead rolled out progressively with real-time health monitoring. This allows our observability tools to catch problems and revert issues before they affect your traffic. In order to catch potentially dangerous deployments before they reach production, we've identified high-risk configuration pipelines, and built new tools to manage configuration changes better. For products that run on our network processing customer traffic and receive configuration changes, we no longer deploy these changes instantly across the

When we first launched Workers eight years ago, it was a direct-to-developers platform. Over the years, we have expanded and scaled the ecosystem so that platforms could not only build on Workers directly, but they could also enable their customers to ship code to us through many multi-tenant applications. We now see on Workers: Applications where users describe what they want, and the AI writes the implementation. Multi-tenant SaaS where every customer's business logic is, at runtime, some TypeScript the platform has never seen before. Agents that write and run their own tools. CI/CD products where every repo defines its own pipeline. Last month, when we shipped the Dynamic Workers open beta , we gave those platforms a clean primitive for the compute side: hand the Workers runtime some code at runtime, get back an isolated, sandboxed Worker, on the same machine, in single-digit milliseconds. Durable Object Facets extended the same idea to storage — each dynamically-loaded app can have its own SQLite database, spun up on demand, with the platform sitting in front, as a supervisor. Artifacts did the same for source control : a Git-native, versioned filesystem you can create by the tens of millions, one per agent, one per session, one per tenant. So, we have dynamic deployment for storage and source control. What’s next? Today, we are bridging durable execution and dynamic deployment with Dynamic Workflows . The gap between durable and dynamic execution

A Brazilian tech firm that specializes in protecting networks from distributed denial-of-service (DDoS) attacks has been enabling a botnet responsible for an extended campaign of massive DDoS attacks against other network operators in Brazil, KrebsOnSecurity has learned. The firm’s chief executive says the malicious activity resulted from a security breach and was likely the work of a competitor trying to tarnish his company’s public image. An Archer AX21 router from TP-Link. Image: tp-link.com. For the past several years, security experts have tracked a series of massive DDoS attacks originating from Brazil and solely targeting Brazilian ISPs. Until recently, it was less than clear who or what was behind these digital sieges. That changed earlier this month when a trusted source who asked to remain anonymous shared a curious file archive that was exposed in an open directory online. The exposed archive contained several Portuguese-language malicious programs written in Python. It also included the private SSH authentication keys belonging to the CEO of Huge Networks , a Brazilian ISP that primarily offers DDoS protection to other Brazilian network operators. Founded in Miami, Fla. in 2014, Huge Networks’s operations are centered in Brazil. The company originated from protecting game servers against DDoS attacks and evolved into an ISP-focused DDoS mitigation provider. It does not appear in any public abuse complaints and is not associated with any known

Coding agents are great at building software. But to deploy to production they need three things from the cloud they want to host their app — an account, a way to pay, and an API token. Until now these have been tasks that humans handle directly. Increasingly, agents handle them on the user’s behalf. The agent needs to perform all the tasks a human customer can. They’re given higher-order problems to solve and choose to use Cloudflare and call Cloudflare APIs. Starting today, agents can provision Cloudflare on behalf of their users. They can create a Cloudflare account, start a paid subscription, register a domain, and get back an API token to deploy code right away. Humans can be in the loop to grant permission and must accept Cloudflare's terms of service, but no human steps are otherwise required from start to finish. There’s no need to go to the dashboard, copy and paste API tokens, or enter credit card details. Without any extra setup, agents have everything they need to deploy a new production application in one shot. And with Cloudflare’s Code Mode MCP server and Agent Skills , they’re even better at it. This all works via a new protocol that we’ve co-designed with Stripe as part of the launch of Stripe Projects . We’re excited to launch this new partnership with Stripe, and also to offer $100,000 in Cloudflare credits to all new startups who incorporate using Stripe Atlas . But this new protocol also makes it possible for any platform with signed-in users to integrate with Cloudflare in the same way Stripe does, with zero friction for the end user. How it works: zero to production without any setup or manual steps

LibAFL is all the rage in the fuzzing community these days, especially with LLVM’s libFuzzer being placed in maintenance mode . Written in Rust, LibAFL claims improved performance, modularity, state-of-the-art fuzzing techniques, and libFuzzer compatibility . For these reasons, I set out to add LibAFL support to Ruzzy , our coverage-guided fuzzer for pure Ruby code and Ruby C extensions. This gives Ruby developers and security researchers access to a more advanced and actively maintained fuzzing engine without changing how they write their fuzzing harnesses. Ruzzy was originally built on top of LLVM’s libFuzzer, so using LibAFL’s compatibility layer should be easy enough. However, digging around in the internals of complex systems is never quite as simple as it seems. In this post, I will investigate some of the deep plumbing inside these fuzzing engines, take a detour into executable and linkable format (ELF) files, and ultimately add LibAFL support to Ruzzy. Building with libafl_libfuzzer Ruzzy currently supports Linux, so I use a Dockerfile for development and for production fuzzing campaigns. To that end, using a similar Dockerfile for LibAFL support is the simplest integration point. LibAFL provides excellent documentation a

That works, right up until the pentest […] The post What CREST Means for Your Next Synack Engagement appeared first on Synack .
The war in Iran has drawn attention to arrests in the United Arab Emirates over online content, but the legal framework behind that enforcement has existed for years.

AI agents may soon be buying your stuff for you. The FIDO Alliance has teamed up with Google and Mastercard to try to ensure that shopping in the near future isn't a complete disaster.
In the first quarter of 2026, government-directed shutdowns figured prominently, with prolonged Internet blackouts in both Uganda and Iran, a stark contrast to the lack of observed government-directed shutdowns in the same quarter a year prior. This quarter, we also observed a number of Internet disruptions caused by power outages , including three separate collapses of Cuba's national electrical grid. Military action continued to disrupt connectivity in Ukraine and also impacted hyperscaler cloud infrastructure in the Middle East. Severe weather knocked out Internet connectivity in Portugal, while cable damage disrupted connectivity in the Republic of Congo. A technical problem hit Verizon Wireless in the United States, and unknown issues briefly disrupted connectivity for customers of providers in Guinea and the United Kingdom. This post is intended as a summary overview of observed and confirmed disruptions and is not an exhaustive or complete list of issues that have occurred during the quarter. A larger list of detected traffic anomalies is available in the Cloudflare Radar Outage Center . Note that both bytes-based and request-based traffic graphs are used within this post to illustrate the impact of the observed disruptions, with the choice of metric generally made based on which better illustrates the impact of the disruption.

SIEM is not enough. Classical DFIR is not the full answer either. And “better logging” is too weak a frame. The real gap is evidentiary continuity in modern, cloud-heavy, application-driven environments.
After i updated it i closed it and a white screen with a logo like this https://preview.redd.it/uu1nklpdjwxg1.png?width=270&format=png&auto=webp&s=00db4e765f7348eb8dd29c42df79ae988d11cabf thats next to the file name popped up, it was instant so im not sure if its malware and i have super bad anxiety and not sure if this is something to do with the download setup modrinth uses or what, ik this is pretty specific so if no one can help its completly fine. Not sure if this is off topic and im freaking out and dont know what community to post this in.
On paper, the vast majority of crisis plans look reasonable, actionable and complete. Once the rubber hits the road, however, chaos emerges quickly. This is where tabletop simulations come into play. Tabletops Exercises (TTX) simulate real-world crises in a controlled environment. They introduce time pressure, incomplete information, and uncertainty, forcing teams to adapt and revealing whether plans hold up under stress. Over the years we have facilitated many tabletop exercises, ranging from small teams of IT teams to full executive crisis staff. The scenarios vary, but the findings are remarkably consistent. Here are some of the most important learnings from the tabletop exercises and real incidents

Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite This is so "peak 2026" - writing an equality policy to ensure people treat our AI bot with the same respect as they do their human counterparts. It's intentionally a bit tongue-in-cheek, but it's there for a purpose: we simply don't have the capacity to deal with every request we get, and we need Bruce to be the coalface of support. I did wonder, when having ChatGPT create this, whether there's some deeper psychology behind the importance of interacting politely with bots, or indeed whether there will ever be an actual (like, serious) standard or law around treating bots with respect. Has this been in a movie somewhere? Let me know, but for now, I'll drop the (slightly revised) policy below, just for the laughs 藍
