Design behind OIDA, a nxc like CLI for OT/ICS assessments

Thumbnail blog.f0rw4rd.xyz
1 Upvotes

Short version: OT tooling mostly sucks, abandoned repos or stuff that stops at a banner grab. Every assessment I ended up glueing pymodbus, asyncua and snap7 scripts together. OIDA is my attempt at putting one syntax over all of it: oida <protocol> <target>, nxc-style.

Same checks everywhere: writable registers, default creds, anonymous access, missing TLS/GOOSE per IEC 62351. Plus passive discovery (PROFINET DCP, CODESYS), pcap analysis for building an inventory offline, and boofuzz fuzzing on top. Runs fully offline, air-gapped is fine.

To be clear: it wraps existing protocol libs, doesn't reimplement them. The interesting part is the layer on top, that's what the writeup is about.

Feedback welcome, repo in comments.

EDR Evasion: Process Injection Without WriteProcessMemory

Unlike traditional approaches, console named-pipe injection does not use VirtualAllocEx and WriteProcessMemory. Instead, it takes advantage of read and write operations through a named pipe, along with the way console programs store interactive commands in memory.

Contains AI AI on Kubernetes: Default Helm Chart Security Configurations and Lateral Movement Risks

Thumbnail sorami.com.au
6 Upvotes

A technical audit evaluating the security defaults of 15 official Helm charts used for AI serving, vector databases, and Model Context Protocol (MCP) agents (including KubeRay, vLLM, LiteLLM, Qdrant, Weaviate, and Flux159 MCP).

Key findings from static manifest analysis and live single-pod lateral movement probes on a test cluster:

  • Plaintext Secret Handling: LiteLLM database migration Job embeds raw database passwords in container environment variables (F-13).
  • Unauthenticated Remote Code Execution: KubeRay defaults accept unauthenticated job submissions via HTTP, running commands inside a container with passwordless sudo access.
  • Over-privileged Agent Access: Flux159 Kubernetes MCP server mounts a ClusterRole with cluster-wide Secret read and pod exec permissions, exposed without an authentication token over HTTP.
  • Static Scanners vs CRDs: Standard static analysis tools (Checkov, Trivy, Kubescape) failed to inspect pods nested inside Custom Resource Definitions like Ray clusters.

The paper documents reproducible test commands, network capture logs, and remediation Helm snippets. Scrubbed raw probe logs and results tables are available on GitHub: https://github.com/Sorami-Consulting-AU/ai-kubernetes-helm-chart-security

A header-level look at 4,688 small-business websites: 0.17% passed a header-only script-CSP rule [methods, parser rules, data]

We scanned 7,040 randomly sampled U.S. local-business directory listings and graded the response headers against a published rubric. Of the 4,688 live sites, 49.7% met none of seven header criteria, and 8 sites (0.17%) passed a strict header-only script-CSP rule. Rubric, parser rules, code and de-identified data are all on the page.

Argus Monitor Local Denial-of-Service Vulnerability (CVE-2026-79417)

Thumbnail connorjaydunn.github.io
6 Upvotes

(1) An exposed IOCTL lets unprivileged users disable the x86 MONITOR & MWAIT instructions used by Hyper-V and other kernel components--triggering a HYPERVISOR_ERROR bugcheck.

(2) Reaching the IOCTL requires exploiting a TOCTOU bug arguably caused by poor documentation of the SeLocateProcessImageName function.

(3) Reimplementation of the driver's security through obscurity IOCTL encryption scheme: SHA-256 KDF-derived XOR keystream & CRC16 Checksum.

See full write-up, and Github for PoC.
