I built 99 adversarial PE fixtures to stress‑test parsers — here’s what they reveal about malformed binaries
Consider a cached access key on a single Windows machine. It got there the way most cached credentials do - a user logged in, and the key stored itself automatically. Standard AWS behavior. No one misconfigured anything or violated a policy. Yet that single key, which was easily accessible to a minor-league attacker, could have opened a path to some 98% of entities in the company's cloud
I just wrapped a 99‑fixture adversarial PE corpus for IOCX — deterministic, spec‑aware, malformed‑but‑parseable binaries, each isolating a single structural anomaly. The whole thing is only 250 KB and it already helped tighten up an unreleased validator. IOCX now walks even the most pathological PEs with confidence. Honestly, this is the most fun I’ve had with PE internals in years. Happy to share details if anyone’s curious. Github: [https://github.com/iocx-dev/iocx](https://github.com/iocx-dev/iocx)

After my last post on the death of the 90-day window ([https://blog.himanshuanand.com/2026/05/the-90-day-disclosure-policy-is-dead/](https://blog.himanshuanand.com/2026/05/the-90-day-disclosure-policy-is-dead/)), the loudest critique I got was: 'Great complaint, what's the proposal?' This is the proposal. It is an informal RFC on how we actually have to change engineering architecture when LLM-assisted bug hunting means the exploit lands before the patch.

Cloudflare and Anthropic have collaborated to integrate Claude Managed Agents with Cloudflare Sandboxes. Our new integration gives you more control over your agent sandboxes, secures connections to private services, and improves observability. In the past year, Cloudflare’s Developer Platform has expanded to give more developers the tools they need to run agents at scale. This includes: Sandboxes for full stateful Linux microVMs at scale Agents SDK , providing simple and customizable agent framework Browser Run , which gives agents fully programmable and observable browsers Dynamic Workers , allowing for dynamic sandboxed code execution at massive scale Our goal is to make Cloudflare the simplest, most secure, and most programmable cloud for agents. Integrating with Claude Managed Agents is another step in this direction. You can run your agent loop on the Claude Platform, while using Cloudflare to execute code, secure connections, and run custom tool calls. To get going in just minutes, we’ve created a default deployment template that gives you the following: Enhanced security - Run all agent traffic through customizable proxies. This allows you to securely inject credentials, prevent data exfiltration, and better observe how your agents interact with the outside world. Sandbox control and observability - Get detailed sandbox metrics and logs. SSH into running machines. Customize sandbox images.

Until this past weekend, a contractor for the Cybersecurity & Infrastructure Security Agency (CISA) maintained a public GitHub repository that exposed credentials to several highly privileged AWS GovCloud accounts and a large number of internal CISA systems. Security experts said the public archive included files detailing how CISA builds, tests and deploys software internally, and that it represents one of the most egregious government data leaks in recent history. On May 15, KrebsOnSecurity heard from Guillaume Valadon , a researcher with the security firm GitGuardian . Valadon’s company constantly scans public code repositories at GitHub and elsewhere for exposed secrets, automatically alerting the offending accounts of any apparent sensitive data exposures. Valadon said he reached out because the owner in this case wasn’t responding and the information exposed was highly sensitive.

AudioHijack: adversarial audio attacks on generative voice models transfer from open weights to Microsoft and Mistral production systems
Interesting new research you may have heard of on attacking large audio language models. The attack is called AudioHijack and the part worth paying attention to is that adversarial clips built against open models transferred to commercial Microsoft and Mistral systems sharing the same architecture. OpenAI and Anthropic are harder targets but the team thinks shared open-source audio encoders are a viable path in, and they're working on it. The manipulations are shaped to sound like natural reverberation instead of added noise, so you can't really hear them. Threat model only requires controlling the audio the model processes, not the user's prompt. So: poisoned YouTube clips, music, voice notes, Zoom audio fed to transcription, and the team also says they've gotten this working against live voice chats in real time (unpublished). Six attack categories demonstrated. Refusing user requests, returning false info, inserting malicious links, swapping persona, claiming it can't process audio, and triggering unauthorized tool use. On the technical side, two things stood out to me. First, generative audio models tokenize the input, which kills the fine-grained gradient signal older adversarial audio work relied on, so they approximated it. Second, they explicitly hijack the attention mechanism by scoring how much attention the model pays to the adversarial audio vs. the user instruction and feeding that back into the optimization. Defenses are where it gets bleak. Few-shot prompting with examples of malicious instructions cut attack success by 7%. Self-reflection caught 28%. Monitoring internal attention patterns was the only thing that actually worked, and an attacker who knows about it can dial back the attention manipulation and take a small hit to success rate to evade it. Microsoft acknowledged the work and pointed at developer-side mitigations. Mistral didn't respond. Text prompt injection at least leaves visible artifacts. Audio doesn't, and we don't really have a good story for this yet. Thoughts?
I am working on a pre-MVP evidence readiness artifact and would value practitioner feedback on the output model.
Hello. I've shared feedback and blog posts before —some of you may remember-. For some time now, I've been developing a project related to the industry (CS & DFIR/IR), and thanks to the valuable feedback I've gathered from you, I've made significant progress. I'm now in the phase of pre-MVP validation and gathering expert opinions. Thank you in advance, and I apologize if I've caused any inconvenience. Question: The artifact is generated from existing security records and public fixture data. It includes source summaries, reliability reasons, limitation statements, manifests, hash lists, and package verification output. Scope boundaries: - it does not claim legal admissibility; - it does not prove original source truth; - it is not a SIEM, DFIR lab tool, threat detector, or forensic acquisition tool; - it focuses on ingestion-onward integrity and handoff clarity. The question is not "would you buy this product?" The question is whether this kind of package would help during IR, audit, insurance, legal, or internal investigation handoff. Specific feedback I am looking for: 1. Are source reliability and limitations clear enough? 2. Does the artifact separate package integrity from upstream source trust? 3. What uncertainty is still hidden? 4. What would make this misleading or unusable in practice? Artifact repo: https://github.com/tracehound/tracehound-pre-mvp-feedback-artifact Virustotal: https://www.virustotal.com/gui/url/dbdbf56e71c39fcfd158babdbb11b57037fa53b333efa27de619ce919278e66e?nocache=1
Overview Three vulnerabilities have been discovered in the SGLang project, two enabling remote code execution (RCE), and one regarding a path traversal vulnerability. In order for an attacker to exploit these vulnerabilities, the multimodal generation mode must be enabled, and an attacker must have network access to the SGLang service. No patch is available at this time, and no response was obtained from the project maintainers during coordination. Description SGLang is an open-source framework for serving large language models (LLMs) and multimodal AI models, supporting models such as Qwen, DeepSeek, Mistral, and Skywork, and is compatible with OpenAI APIs. Three vulnerabilities have been discovered within the tool and are tracked as follows: CVE-2026-7301 The multimodal generation runtime scheduler's ROUTER socket contains a sink that calls pickle.loads() on incoming messages, enabling RCE when exposed to the internet. This vulnerability is distinct from CVE-2026-3060 and CVE-2026-3059, which would be open to the Internet via the ZMQ broker, which automatically binded to all network interfaces without user awareness. CVE-2026-7301 is exposed to the internet by default through the scheduler host, which binds to 0.0.0.0 by default. CVE-2026-7302 The multimodal generation runtime is vulnerable to an unauthenticated path traversal vulnerability, allowing an attacker to write arbitrary files anywhere the server process has write access, by including ../ sequences in the upload filename when sent to specific endpoints. CVE-2026-7304 The multimodal generation runtime is vulnerable to unauthenticated remote code execution when the

Came across this really interesting analysis of a pirated Android movie streaming APK called NetMirror and honestly didn’t expect it to go this deep. At first glance the app looked completely normal: clean UI, React Native based, movies streamed properly. But the analysis found: * emulator/sandbox detection for Genymotion, Nox, BlueStacks, VirtualBox, etc. * Base64-encoded infrastructure domains hidden inside the Hermes JS bundle * staged permission handling for SMS and call log access * WebView credential interception hooks * native libraries containing the same tracking infrastructure references The most interesting part was how it bypassed automated analysis. Hybrid Analysis apparently marked it as “safe” because most of the suspicious logic wasn’t in the Java layer scanners usually inspect — it was hidden inside the React Native Hermes bundle and native libraries. Pretty solid example of how modern Android malware is starting to exploit analysis blind spots in cross-platform frameworks.

For the last few months, we've been testing a range of security-focused LLMs on our own infrastructure. These LLMs help identify potential vulnerabilities in our own systems, so we can fix them – and they also show us what attackers are going to be able to do with the latest models. None of these LLMs has captured more attention than Mythos Preview, from Anthropic. A few weeks ago, we were invited to use Mythos Preview as part of Project Glasswing . We soon pointed it at more than fifty of our own repositories – to see what it would find, and to see how it works. This post shares what we observed, what the models did well and what they didn't, and how the architecture and process around them needs to change, so they can be used at scale. What changed with Mythos Preview Mythos Preview is a real step forward, and it's worth saying that plainly before getting into anything else. We've been running models against our code for a while now, and the jump from what was possible with previous general-purpose frontier models to what Mythos Preview does today is not just a refinement of what came before. It's a different kind of tool doing a different kind of work, and that makes a clean apples-to-apples comparison to earlier models difficult. So rather than trying to benchmark Mythos Preview against general-purpose frontier models, it's more useful to describe what it can actually do, and two features that stood out across the work we did with Mythos Preview: Exploit chain construction - A real attack rarely uses one bug. It chains several small attack primitives together into a working exploit. For instance, it might turn a use-after-free bug into an arbitrary read and write primitive, hijack the control flow, and use return-oriented programming (ROP)
Presently sponsored by: Report URI: Guarding you from rogue JavaScript! Don’t get pwned; get real-time alerts & prevent breaches #SecureYourSite It's a hot topic, the old "pay or don't pay" for hackers not to leak your data. Since recording this a few days ago, we've had Grafana go with the "no pay" approach , and I've seen a raft of commentary around other companies reaching "agreements", which is a much politer way of saying "we paid extortionists a ransom". I'm concerned about the normalisation of ransom payments, and using language that deflects from the criminal nature of it is a big part of that. Instructure's exact words were that they "reached an agreement with the unauthorised actor involved", which really waters down the severity of the whole thing. It looks like, for the time being, "pay or leak" is the new norm... along with nonsensical statements like "the data was returned to us" 路♂️

After months of work, I’m excited to finally share [Brovan](https://github.com/AdvDebug/Brovan), my user-mode binary emulator. Brovan can emulate: \* PE binaries \* ELF binaries \* Memory dumps \* Even partially unknown or unrecognized binaries The goal is to make binary analysis, malware analysis and general binary research more flexible by giving full control over execution, memory, and runtime behavior in a contained environment.

Hey everyone - I built a DFIR tool called **RDPuzzle** and would really appreciate feedback from people who have worked with RDP bitmap cache artifacts. It is a local, browser-based workspace for reconstructing 64x64 RDP cache tiles into larger readable images. The main thing it adds is **neural-assisted reconstruction**: instead of only manually placing tiles, RDPuzzle ranks likely neighboring tiles and can auto-stitch regions using edge-similarity scoring plus a local ONNX edge-matching model. Main features: * Loads RDP cache fragments, including BMC/BIN-style inputs * Manual and semi-automatic tile reconstruction * Neural-assisted neighbor suggestions * Auto-stitching of likely adjacent tiles * Fully local/browser-based processing * OCR for recovered text * Session save/load, undo/redo, and image export * Demo dataset included GitHub: [https://github.com/BZDaniel/RDPuzzle](https://github.com/BZDaniel/RDPuzzle) Live version: [https://bzdaniel.github.io/RDPuzzle/RDPuzzle.html](https://bzdaniel.github.io/RDPuzzle/RDPuzzle.html) Remember to enable AI at the top right corner, and also i currently only recommend running the smaller AI model as the large one needs quantization to run realistically in a browser. I’d especially appreciate feedback on workflow, validation concerns, parser edge cases, false-positive matches, and anything that would make it more useful in real forensic work.
At Cloudflare, we are heavy users of ClickHouse, an open source online analytical processing (OLAP) database. Every day, we make millions of calls to ClickHouse to determine how much users should be billed for their usage of Cloudflare products. If we don't finish those jobs in a timely fashion, the invoices become very difficult to reconcile. This pipeline powers hundreds of millions of dollars in usage revenue, fraud systems, and more, so being delayed has major downstream implications. Which is why it was a big problem when the daily aggregation jobs in ClickHouse – responsible for ensuring Cloudflare’s bills go out – had slowed way down, following a migration. All the usual suspects looked clean: I/O, memory, rows scanned, parts read. Everything we would normally check when a ClickHouse query is slow appeared to be normal. This is the story of how we discovered a hidden bottleneck buried deep within ClickHouse’s internals, and the three patches we wrote to fix it. The setup: a petabyte-scale analytics platform We use ClickHouse to store over a hundred petabytes of data across a few dozen clusters. To simplify onboarding for our many internal teams, we built a system called "Ready-Analytics" in early 2022. The premise is simple: instead of designing new tables, teams can stream data into a single, massive table. Datasets are disambiguated by a namespace , and each record uses a standard schema (e.g., 20 float fields, 20 string fields, a timestamp, and an indexID ). In ClickHouse, the way data is sorted is crucial to query performance. This is where the indexID comes into play. It’s a string field, which forms part of the primary key, meaning that every individual namespace can have its data sorted in a way that is optimal for the queries the owners of that namesp
