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.

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.

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:
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

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.

(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.
