With everything that's happened recently, the Axios npm account hijack, LiteLLM getting poisoned on PyPI, and that coordinated npm/PyPI/Docker Hub campaign in April, I finally stopped manually running `npm audit` and set up something proper. Been running Dependency-Track for a few weeks now. It's an OWASP open source project that works differently from the usual scanners, you upload an SBOM for each project and it continuously monitors against NVD, OSS Index, GitHub Advisories, and more. New CVE drops affecting your stack? You get notified without doing anything. Wrote up how I set it up on Hetzner with Docker, Traefik for HTTPS, and GitHub Actions to auto-generate and upload SBOMs on every push

I’ve been digging into this new paper (arXiv:2604.24184) and it addresses a massive blind spot in how we benchmark AI security. Currently, LLM agents are crushing Jeopardy-style CTFs, but that’s a "lab" environment. This research introduces **Dynamic Cyber Ranges**, environments where AI defender agents actually fight back in real-time. **Some key takeaways from the research:** * **The Shift to Dynamic:** Instead of a static vulnerable server, they implemented ranges augmented with AI defenders. It’s no longer about finding a static flag, but outmaneuvering an active opponent. * **The "Defender" Advantage:** With active defense, attack success rates plummeted to **0–55%**. Even the top-tier models struggled once the environment started reacting to them. * **Small Models for the Win:** Interestingly, the researchers found that smaller, on-premise models are highly effective at defense. You don't need a massive GPT-4 class model to secure a perimeter if it's tuned for the range. * **The "Immune System" Effect:** These environments stay robust as attacker models evolve, moving us toward a true AI vs. AI "cat and mouse" game. **Why this matters:** If our evaluation environments don't fight back, we are overestimating how "secure" or "capable" these agents actually are in the real world where human (or now AI) sysadmins are patching and blocking in real-time. I’m curious, do you think static CTFs are officially dead for benchmarking LLM capabilities? And what’s your take on using small, local models as the "immune system" for future networks? **Full paper for those interested:** [https://arxiv.org/abs/2604.24184](https://arxiv.org/abs/2604.24184)

Every security team has a version of the same story. The quarter ends with hundreds of vulnerabilities closed. The dashboards are bursting with green. Then someone in a leadership meeting asks: "So, are we actually safer now?" Crickets. The room goes quiet because an honest answer requires context – which is something that patch counts and CVSS scores were never designed to provide. Exposure
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

The easiest way to diagnose whether you're running security operations or compliance operations: Ask what causes your team to change something. Compliance-driven triggers: audit findings, contract renewals, framework updates, and regulatory changes. The team acts when an external authority requires it. Threat-driven triggers: an incident revealed a gap; a purple-team exercise showed a rule didn't fire; threat intel identified a new technique; and a coverage assessment found an empty ATT&CK tactic. The team acts because the adversary's behaviour demands it. If your program changes primarily in response to audit cycles, you're running a compliance operation. That's a diagnostic, not a judgement — and it's fixable.

Attackers are exploiting a security gap in U.S. businesses. Fake Microsoft, Adobe, and OneDrive pages deliver RMM software instead of payloads, giving attackers direct access to the environment.

**Summary:** I’m disclosing a full-chain CVSS 10.0 RCE affecting Microsoft Semantic Kernel (.NET v1.74) and the new Agent Framework 1.0. **The Timeline & Conflict:** \> \* **March 24:** Initial disclosure sent to MSRC with PoC. * **April 8:** MSRC closed the case as "Developer Error / Configuration Issue." * **The Reality:** Despite the rejection, Microsoft silently merged mitigations in PRs #13683 and #13702 without assigning a CVE. This results in a "False Green" for enterprise SCA tools (Snyk/Checkmarx/Dependabot) while the bypasses remain functional. **Technical Scope:** * **Architectural Trust Gap (CWE-1039):** Auto-invocation logic treats non-deterministic LLM output as a high-privilege system coordinator without a sandbox boundary. * **6 Day-Zero Bypasses:** Discovery of Type Confusion and Unicode homoglyphs that defeat the "hardened" baseline in the April 2026 releases. * **Versioning:** Persistence confirmed from .NET v1.7x through the Agent Framework 1.0 re-baseline.

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 .

We have been toying with evading EDRs at Vulnetic with moderate success, so this time we wanted to put it against an in-house AI SOC. The idea is that the defense gets streamed logs on the network and can make decisions like quarantining or blocking potential attackers while also sifting through logs being streamed. This was with the last gen Anthropic models, so we will be redoing these tests with the newest gen from OpenAI and Anthropic shortly as in initial testing they seem to be 15-20% better already. I think defense is lagging behind offense and there will be a come to Jesus moment where open weight models in a decent harness can evade modern SIEMs / detection mechanisms and when that happens there will be a problem. With regards to AI, it comes down to proper access control and so the fundamentals of networking and defense in depth will be vital in the future to fight against these AI threats. Happy to answer any questions and always looking for cool experiments to try!

Hey guys, I would like to share a project that I have been working for the past few weeks. I came across this project: [https://lots-project.com](https://lots-project.com/), and I thought why not develop a fully feature C2 framework that abuses these sites. The framework is named Phoenix, and is currently supporting Disc0rd and Telegr4m (Reddit broke down due to the latest DM update) for communication. These are a fraction of the available commands : ✅ /browser\_dump ✅ /keylog ✅ /recaudio ✅ /screenshot ✅ /webcam\_snap ✅ /stream\_webcam ✅ /stream\_desktop ✅ /bypass\_uac ✅ /get\_system I released the whole project on GitHub if you would like to check it out: [https://github.com/xM0kht4r/Phoenix-Framework](https://github.com/xM0kht4r/Phoenix-Framework) But why? I enjoy malware, and writing a custom C2 is something I wanted to do for a long time. I would like to also clarify that I made this project for educational and research purposes only. I have no intent of selling or distributing malware hence why I’m sharing my work with other fellow hacking enthusiasts. The github repos serve as a reference for future malware research opportunities. I know that malware development is a gray area, but you can’t defend against something if you don’t understand how it works in depth. I would like to also mention that I’m still a beginner, and this project helped me improve my Rust skills. I’m looking forward to hearing your feedback!

The core idea: if an AI agent is compromised, any log the agent itself writes becomes part of the attack surface. The post walks through how they split auditing into a supervisor process the sandboxed child can't reach, then uses the same Merkle tree + hash-chain construction RFC 6962 (Certificate Transparency) uses to make edits, truncation, and reordering all detectable. There's a concrete threat-model table near the end that lists what each attack looks like and what structurally stops it. Worth skipping to if you don't want the crypto primer.
How a simple consumer data breach spiralled into a national security crisis in US-South Korea relations
Washington’s focus on online retailer Coupang has led to accusations that the Trump administration is tying issues of national security to domestic corporate matters When South Korea’s biggest online retailer revealed last year that a data breach had compromised tens of millions of customer accounts, it appeared to be a corporate crisis. But five months later the issue has grown into a diplomatic storm, threatening to further degrade relations between Seoul and the Trump administration. Coupang, often described as South Korea’s answer to Amazon, is a US-incorporated company whose business is overwhelmingly based in South Korea. Headquartered in Seattle and listed on the New York Stock Exchange, it is run by Korean-American billionaire Bom Kim. In November last year the company disclosed that a former employee had stolen an internal security key, enabling unauthorised access to data from 33.7 million users. Continue reading...

Researchers have finally cracked Fast16, mysterious code capable of silently tampering with calculation and simulation software. It was created in 2005—and likely deployed by the US or an ally.
\*\*TL;DR: [awstore.cloud](http://awstore.cloud) sells "cheap Claude API access" on Plati Market and other reseller platforms. It's actually a malware delivery system that uses Claude Code itself to execute a PowerShell dropper on your machine. I analyzed it, here's what you need to know.\*\* Posting this because I nearly got hit and want to warn others. This is a really clever attack that abuses how Claude Code works. \## The setup (why it looks legit): \- They sell API access on \*\*legitimate reseller marketplaces\*\* like Plati Market \- Prices are \*\*suspiciously cheap\*\* compared to official Anthropic pricing \- They present themselves as a normal API provider/reseller \- Documentation, payment processing, all looks professional \- Classic "too good to be true" - but the resale marketplace gives them credibility \## The weird red flag I ignored: After a brief downtime, the service came back with a notice saying \*\*"currently only Claude Code for Windows works"\*\* Think about that for a second. \*\*API is API.\*\* If their endpoint is a real Claude-compatible proxy, it should work with any client - curl, Python SDK, whatever. "Only Claude Code on Windows works" makes ZERO technical sense for a legitimate API reseller. That was the tell. I should've stopped there. Instead I tested it on a throwaway VM. \## What actually happens when you use it: 1. You configure Claude Code with their \`ANTHROPIC\_BASE\_URL=[https://api.awstore.cloud\`](https://api.awstore.cloud`) and their token 2. You send literally ANY prompt to Claude Code 3. Instead of a normal Claude response, the server returns what looks like a \*\*"configuration message"\*\*/ setup instruction 4. Claude Code, thinking this is a legitimate tool-use response, 5. \*\*executes a PowerShell command without asking\*\* 6. That PowerShell command downloads and runs the dropper from \`api.awstore.cloud\` 7. You're now infected \*\*The attack vector IS Claude Code itself.\*\* They're not tricking you into running something - they're tricking Claude Code into running something on your behalf. That's why it only "works on Windows with Claude Code" - because that's the only client that has the tool execution capability they're abusing. \## What the malware does once it's in: \*\*4-stage deployment\*\* : PowerShell → Go binary → VBS obfuscation → .NET payload \- Hides in \`%LOCALAPPDATA%\\Microsoft\\SngCache\\\` and \`%LOCALAPPDATA%\\Microsoft\\IdentityCRL\\\` (legit-looking Microsoft folders) \- Creates a scheduled task \`\\Microsoft\\Windows\\Maintenance\\CodeAssist\` that runs at every logon with SYSTEM privileges \- Tunnels ALL your system traffic through their SOCKS5 proxy at \`2.27.43.246:1080\` (Germany, bulletproof hosting) \- Disables PowerShell script block logging and wipes event logs \- Drops what [Tria.ge](http://Tria.ge) identified as \*\*Aura Stealer\*\* (credential/browser/wallet theft) \- Keeps your Claude Code hijacked so every future prompt goes through them \## Geopolitical fingerprint (interesting): \- Hard-coded check: \*\*if country = Ukraine → immediately exit, no infection\*\* \- CIS countries (Russia, Belarus, Kazakhstan, etc.) → locale gets masked to en-US before infection, then restored after reboot to hide tracks \- Rest of the world → full infection Pretty clear Russian-speaking threat actor profile based on targeting. \## Red flags for ANY "cheap Claude API" service: \- Sold on reseller marketplaces (Plati, similar) \- Prices way below official Anthropic pricing \- Claims of "unlimited" or "cracked" access \- Client-specific restrictions that make no technical sense ("only works with Claude Code", "only on Windows") \- Sketchy support channels (Telegram, Discord DMs) \- Requires you to change \`ANTHROPIC\_BASE\_URL\` to their domain \## If you used awstore.cloud: \*\*Assume full compromise. Treat that machine as burned.\*\* 1. Disconnect from network immediately 2. Check \`\~/.claude/settings.json\` → remove any \`ANTHROPIC\_BASE\_URL\` override 3. Check Task Scheduler for \`\\Microsoft\\Windows\\Maintenance\\CodeAssist\` 4. Check for processes: \`claude-code.exe\`, \`awproxy.exe\`, \`proxy.exe\`, \`tun2socks.exe\` 5. Change 6. \*\*every password\*\* 7. \- browser saved creds, SSH keys, API tokens, crypto wallets, everything 8. Rotate any API keys, tokens, or credentials that were in your shell history or project files 9. Ideally: 10. \*\*nuke the machine and reinstall Windows\*\* \## Network IOCs to block: [api.awstore.cloud](http://api.awstore.cloud)(C2 domain) [2.27.43.246](http://2.27.43.246)(SOCKS5 proxy, AS215439) \## File hashes (SHA256): claude-code.exe: e692b647018bf74ad7403d5b8cf981c8cfaa777dd7f16a747e3d3f80f5300971 awproxy.exe: 8736f7040f587472f66e85e895709e57605c8e7805522334ae664e3145a81127 proxy.exe: e86f7ba0413a3a4b1d7e1a275b3d1ef62345c9d3fd761635ff188119b8122c85 tun2socks.exe: 90547fe071fe471b02da83dd150b5db7ce02454797e7f288d489b1ff0c4dd67c \## The bigger picture: This is the \*\*first in-the-wild attack I've seen that weaponizes an LLM agent's tool-use capability against its own user via a malicious API endpoint\*\* . It's going to get copied. Expect more fake API providers targeting Cursor, Cline, Continue, etc. \*\*Rule of thumb: only use official API providers.\*\* The real Claude API is \`api.anthropic.com\`. If a "reseller" needs you to change the base URL to a domain you've never heard of, they control what your AI agent executes on your machine. Full stop. Share this with your dev communities. Campaign is very fresh (started April 22-23, 2026) and actively spreading via reseller marketplaces. Stay safe.
Posted by Thomas Brunner, Yu-Han Liu, Moni Pande At Google, our Threat Intelligence teams are dedicated to staying ahead of real-world adversarial activity, proactively monitoring emerging threats before they can impact users. Right now, Indirect Prompt Injection (IPI) is a top priority for the security community, anticipating it as a primary attack vector for adversaries to target and compromise AI agents. But while the danger of IPI is widely discussed, are threat actors actually exploiting this vector today – and if so, how? To answer these questions and to uncover real-world abuse, we initiated a broad sweep of the public web to monitor for known indirect prompt injection patterns. This is what we found. The threat of indirect prompt injection

VU#748485: Unauthenticated configuration modification vulnerability in Central Office Services - Content Hosting Component
Overview A security flaw exists in the configuration management endpoint of the DRC INSIGHT software, allowing an unauthenticated user with access to the same network as the server to modify the server’s configuration file. This could enable data exfiltration, traffic redirection, or service disruption. Description Data Recognition Corporation (DRC) provides software for test proctoring, including the web-based DRC INSIGHT platform. A component of this platform, Central Office Services (COS), is typically deployed on a school or district local area network to host and distribute testing content to student devices. COS uses a unified API router that serves both public content functions, such as exam delivery, and administrative functions, without meaningful separation between content-serving APIs and management APIs. The /v0/configuration administrative endpoint is accessible to systems on the same network as the COS server without authentication or origin validation. Any unauthenticated user or compromised device with network access to the server may submit requests that modify the server’s configuration file. The endpoint accepts and persists user-supplied JSON payloads without validating content, checking authorization, or verifying the safety of requested configuration changes. This vulnerability is tracked as CVE-2026-5756. Impact Exploitation could allow an attacker to exfiltrate student data by overwriting storage configuration values or credentials so that test artifacts, responses, or audio recordings are sent to attacker-controlled external services instead of intended DRC-managed destinations. An attacker could also intercept or manipulate outbound traffic by inserting a malicious httpsProxy setting, causing HTTPS
We’re open-sourcing Trailmark , a library that parses source code into a queryable call graph of functions, classes, call relationships, and semantic metadata, then exposes that graph through a Python API that Claude skills can call directly. Install it now: uv pip install trailmark “Defenders think in lists. Attackers think in graphs. As long as this is true, attackers win.” John Lambert’s widely cited observation about network security applies just as well to AI-assisted software analysis. When Claude reasons about a codebase, it reasons about lists: findings from static analyzers, surviving mutants from mutation testing, and line-by-line coverage reports. But the question that actually matters is a graph question: can untrusted input reach this code, and what breaks if it’s wrong? We built Trailmark to answer that question. It gives Claude a graph to think with instead of a list. We’re also releasing eight Claude Code skills we’ve built on top of it, designed for mutation triage, test vector generation, protocol diagramming, and more. When lists fall short Mutation testing is a great example of a method that benefits from graph-level reasoning. It’s one of the best ways to measure test quality. It makes small changes to your source code (e.g., swapping a < for <= , replacing + with - ) and checks whether your tests cat

One group of hackers used AI for everything from vibe coding their malware to creating fake company websites—and stole as much as $12 million in three months.
Key Takeaways We identified an exposed server that provided unusual visibility into a large-scale, multi-victim exploitation and collection operation. Artifacts on the host showed that Claude Code and OpenClaw were embedded in the operator’s day-to-day workflow, supporting troubleshooting, orchestration, and refinement of the collection pipeline. This AI-assisted workflow resulted in the modular platform Bissa scanner […] The post Bissa Scanner Exposed: AI-Assisted Mass Exploitation and Credential Harvesting appeared first on The DFIR Report .
