AI security CTF from a CNCF project - useful for understanding LLM/agent attack patterns from the defense side (June 17-22)
Hi r/blueteamsec, I'm a DevRel at KubeArmor (open source CNCF runtime security project). We're hosting an AI security CTF from June 17-22, and while it's an offensive exercise, I think blue teamers get a lot of value from understanding these attack paths firsthand. Free, browser-based, no setup. $1,000+ prizes. **The three tracks map to real defensive concerns:** 1. **Prompt Injection Lab** \- If your org is deploying LLM-powered features, these are the exact attacks your guardrails need to handle: system prompt override, persona drift, multi-turn memory manipulation, indirect injection via context documents, keyword filter bypass 2. **Agent Workflow Hijack** \- For anyone building or securing agentic AI systems: tool misuse through prompt manipulation, search result poisoning, approval gate bypass, agent memory as an injection surface, multi-tool chain exploitation 3. **Hidden API & Guardrail Bypass** \- The classic "your safety layer isn't as airtight as you think": debug endpoint exposure, safety mode parameter tampering, export feature abuse, pre-redaction response interception, weak token replay Playing through these gives you a concrete mental model of what to test for and defend against when your team ships AI features.

Lawmakers in both houses of Congress are demanding answers from the U.S. Cybersecurity & Infrastructure Security Agency (CISA) after KrebsOnSecurity reported this week that a CISA contractor intentionally published AWS GovCloud keys and a vast trove of other agency secrets on a public GitHub account. The inquiry comes as CISA is still struggling to contain the breach and invalidate the leaked credentials. On May 18, KrebsOnSecurity reported that a CISA contractor with administrative access to the agency’s code development platform had created a public GitHub profile called “ Private-CISA ” that included plaintext credentials to dozens of internal CISA systems. Experts who reviewed the exposed secrets said the commit logs for the code repository showed the CISA contractor disabled GitHub’s built-in protection against publishing sensitive credentials in public repos. CISA acknowledged the leak but has not responded to questions about the duration of the data exposure. However, experts who reviewed the now-defunct Private-CISA archive said it was originally created in November 2025, and that it exhibits a pattern consistent with an individual operator using the repository as a working scratchpad or synchronizati

"When performing security assessments on HTTP-based applications, whether web, mobile, APIs, or thick clients, the standard workflow is straightforward: put Burp Suite in the middle, and you’re good to go. Most of the time, that’s all you need. Every now and then, though, you run into a small but significant class of applications where that workflow breaks down. Custom protocols, payload encryption, request signatures, replay protection, non-standard encoding, these are the scenarios where you can no longer work manually the way you’re used to, and where Burp’s automated tools (Intruder, Scanner) stop being useful because they’re operating on data they can’t meaningfully read or modify. In this talk I took one of these complexities as example, additional payload encryption**,** and used it as a vehicle to explore advanced approaches based on **custom Burp extensions** to restore full testability: working manually in Proxy and Repeater, running automated tools like Intruder and Scanner, and even driving external tools like SQLMap through Burp, all as if the complexity simply weren’t there."

1 Introduction This article provides a technical analysis of how many Windows kernel mode drivers can be interacted with from user mode without the hardware they were developed for. This work was motivated by driver-oriented vulnerability research and the need to evaluate the exploitability of individual findings, which frequently affect code whose reachability is hardware-gated. The
In March 2026, attackers exploited a pull_request_target misconfiguration in the aquasecurity/trivy-action GitHub Action to exfiltrate organization and repository secrets, then used those credentials to backdoor LiteLLM on PyPI (see Trivy’s post-mortem for the full timeline). zizmor is a static analyzer that GitHub Actions users run to catch exactly these misconfigurations before they ship. When GitHub Actions added support for YAML anchors in September 2025, a small but high-value slice of the ecosystem started writing workflows that zizmor could only analyze on a best-effort basis. Over the past three months, Trail of Bits collaborated with the zizmor maintainers to bring zizmor ’s anchor support up to full coverage. First, we fixed parsing bugs that caused crashes, produced wrong-location findings, and silently mishandled aliased values. Second, we surfaced deserialization edge cases that broke zizmor on otherwise valid workflows. Finally, we helped align zizmor ’s expression evaluator with GitHub’s own Known Answer Tests . We validated all of this against a new corpus of 41,253 workflows from 6,612 high-value open-source repositories. The result: 20 filed issues, 15 merged pull requests. Building the test corpus To u

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.

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.

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♂️

Businesses are advised against paying – but many are prepared to deal to protect users’ privacy After a week of outages, hundreds of millions of students’ data stolen, delayed assignment due dates and school login pages being defaced by hackers, the US tech firm Instructure – which operates the education platform Canvas, used by education providers worldwide – announced it had “reached an agreement with the unauthorised actor” behind the ransomware attack. Experts read the careful language as a sign that a ransom has been paid. The company has not confirmed this. Continue reading...

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. Building this involved a lot of work around emulation, syscall handling, memory management, binary loading and parsing, and there’s still much more to improve, but it’s finally at a stage where I’m happy to share it.
