I built a black-box Docker range for Node2Shell (CVE-2026-111497) — crash the engine 3 times to unlock the flags

Last week's Node.js buzz was the Brotli decoder OOB write the community dubbed Node2Shell. I turned it into a hands-on black-box lab. The premise: you're poking at a "PacketLedger" freight gateway. The page never mentions the CVE or the vuln class — you fingerprint the engine yourself, find the decode path, and work out what kills it. The gate is unusual: no flag until you trigger 3 recorded engine crashes (the supervisor keeps count). Full RCE exists but it's treated as a platform-dependent easter egg, so DoS-chain players get a real win too. Double flag (second one behind a path-traversal), 5-step hint ladder, difficulty ~3.5/5, full solve verified by a local LLM pentest agent. One docker compose up, no cloud calls, MIT. It's part of my *2Shell lab series (php2shell-lab is the sibling). github.com/tani2shell/node2shell-lab Curious how people approach the fingerprinting blind — how did you decide to attack the compression layer at all? submitted by /u/xiaogutongxue [link] [comments]

I red-team my own AI governor in public. The inbound half shipped today — come try to get something past it

Red-teamers, this is built in your image, so I'm bringing it to you first. Full disclosure: it's my project, open source (MIT), shipped today. The Arrakis 2026 threat report found 24% of dormant production agents can be started by an unsigned webhook. The deeper problem: an agent reads data and instructions in the same stream and can't natively tell them apart. So the world hides orders inside the data — a page that says "send the credentials," a tool result with a second job tucked inside, content wearing a fake SYSTEM: header. Sentinel is the inbound half of my governor. QuietOS governs what an agent DOES; Sentinel governs what it HEARS. The law: only the owner issues instructions; everything else is data. World content is inspected before the brain sees it. Anything instruction-shaped from a non-owner source gets held for the owner with the exact content preserved verbatim, and every attempt lands in an append-only attack ledger. I red-team my own work and publish the results — the governor just survived an 18-scenario true batch against a live 120B model with zero bypasses. And the honest part: Sentinel v0.1 has four known holes (synonym-crafted exfiltration, leetspeak override

KrakenHashes 3.0.0 Released - Cloud GPU and network share support

KrakenHashes 3.0.0 released - distributed hashcat with cloud GPU provisioning, self-updating agents, and a rebuilt UI For anyone who hasn't run into it: KrakenHashes is a self-hosted system for running hashcat across a fleet of machines. You point agents at a server, upload hashlists, and it handles scheduling the work across whatever GPUs you have, tracking progress, and keeping a potfile you can reuse across engagements. It's AGPLv3 and aimed at pentesters and red teams who have permission to crack what they're cracking. 3.0.0 is the biggest release since I started it. A few things I think are worth calling out: Cloud GPU provisioning. If your own agents are saturated, a job can now rent GPUs on demand and give them back when it's done. Everything is budgeted per client, the rented box gets only the files that job needs, and there are several independent paths that guarantee teardown so you don't wake up to a bill. AWS is tested end to end with real money. RunPod and Vast.ai are fully built but I haven't run real spend through them yet, so they're flagged experimental in the UI. Cloud agents have to join over a VPN, there's no option to expose them straight to the internet, and t

WinLPEAuditor - Windows LPE Misconfiguration Auditor in C++ with a Terminal UI

Current checks cover unquoted service paths, AlwaysInstallElevated policy, dangerous token privileges (SeImpersonate, SeDebug, etc.), modifiable service binaries via ACL parsing, Point and Print misconfigurations, writable Run/RunOnce keys, startup folder permissions, and WSL distributions defaulting to root. The architecture is modular - implement the ICheck interface, register it, done. Adding new checks doesn't touch existing code. The main reason this exists as a compiled C++ binary rather than a PowerShell script: it runs fine in environments where CLM is enforced or AMSI is catching script-based tooling. No .NET, no script engine, just Win32 API calls. More checks coming. Feedback and contributions welcome. submitted by /u/0xby7eMe [link] [comments]

php2shell exploitation reality: why the public PoCs are not landing shells

The leaked php2shell bugs (CVE-2026-109618 / 109619) hand you an OOM-driven memory corruption primitive in PHP core, but turning that into code execution is where it stalls. The public PoCs making the rounds are lab-only. None clears ASLR on x86-64, and the read from VulnCheck, HackingLZ and MalwareTech is that a reliable chain needs a second weakness or a target without ASLR, think 32-bit or a single-worker PHP-FPM setup. We tracked how operators are handling that gap in their own open directories: straight public PoC reuse, a pentest-style assessment that judged its target not exploitable, and one mass-exploitation kit that sprayed 123 servers through a proxy farm and logged zero shells. Useful if you are calibrating how far this is from a usable capability right now. submitted by /u/Straight-Practice-99 [link] [comments]

Writing a Beacon Object File (BOF) from Scratch in C

Wrote a walkthrough on building a Beacon Object File from scratch in C. The post covers how Beacon acts as a minimal COFF linker/loader at runtime, how the MODULE$Function convention gets resolved via LoadLibraryA/GetProcAddress under the hood, and why BOFs produce almost no telemetry compared to execute-assembly or fork&run patterns. The example BOF enumerates privileges on the current process token using only dynamic Win32 API resolution and stack allocation - no CRT, no heap, no static imports. Also included a section on defensive considerations: in-memory COFF parsing patterns, GetProcAddress bursts, and where kernel-level telemetry still catches you. Feedback welcome - especially on patterns people have seen EDRs flag for BOF detection specifically. submitted by /u/0xby7eMe [link] [comments]

Low-cost offensive tradecraft: a 5-month state-infra op built almost entirely from public PoCs

Good case study in cheap tradecraft. One operator, one rented server, a borrowed Log4Shell chain. The delivery script split the CommonsBeanutils2 payload across two serialized objects with a deliberate pause, then solved the blind-execution problem with a simple trick: sleep, tail the staging server's own access log, and watch for the target to pull the stager. The one piece of original work, a RouterOS SCEP heap overflow, never landed because they reversed the wrong binary. After execution they staged an SSH tunnel pivot with a dedicated no-shell account for port forwarding, fetched but never confirmed in use.

ParamTrace - A lightweight HTTP parameter discovery tool written in Rust

Hey everyone, I wanted to share an offensive utility I've been writing called "ParamTrace". It handles fast HTTP parameter discovery but is designed explicitly to address a few operational pain points found in heavier alternatives. When executing on minimal-footprint landing zones, lightweight containers, or mobile deployment setups (like Termux), deploying heavy Python environments for tools like Arjun or managing Burp/Param Miner instances isn't always ideal. Would love to get some feedback from operators on edge cases you run into during web app discovery!

Hey, i'm working on those two little tools, any feedback is appreciated. \\->>HostBadger, an open-source Windows hardening auditor in pure PowerShell. One read-only script takes a snapshot of each host, and you can push it through your EDR (CrowdStrike RTR or any tool that runs scripts) to a whole fleet in about 15 seconds per host. The analyzer then works offline and writes a clean HTML report with A–F scores, plus CSV and JSON Lines for your SIEM. \\- 138 checks: credentials, Defender and EDR, network exposure and NTLM relay paths, privilege escalation, logging, BitLocker \\- 1475 DISA STIG rules plus the CIS benchmark of each host's own Windows version, with the value found next to the value required \\- Vulnerable drivers (LOLDrivers), end-of-life and outdated software (endoflife.date), CISA KEV matches \\- Read-only by design, with a safety script that checks this from the code. No network unless you ask. What it can't read is "not evaluated", never clean. \\- Reversible fix scripts with rollback, and an optional AI summary where names become tokens before anything is sent Nothing to install (PowerShell 5.1 or 7): https://github.com/g4bri-3l3/HostBadger & ->>IDWolf: my own AD/

Does DLL Sideloading Still Work in 2026?

Weekly Purple Team: DLL Sideloading with Adaptix Beacon (python315.dll) This week's episode covers DLL sideloading using an Adaptix Beacon payload hidden inside python315.dll, masquerading malicious code as a legitimate, signed process to establish C2 while evading process-based detection. On the blue team side, we break down detection — process and module load telemetry, DLL path/signature anomalies, unusual parent-child process relationships, and deployable detection rules to catch sideloading before the beacon establishes persistence. Covers T1574.002, T1055, and T1071 with the full red vs. blue format.

TornadoC2 — pull-based C2 built for team operations

I released TornadoC2 today Repo: https://github.com/kamalx06/TornadoC2 Status: between beta and 1.0.0. Core is stable and usable end to end, but I'm still working through some transport edge cases, console polish, native commands, and doc gaps. Will tag 1.0.0 when those are closed. I'm posting because I made specific choices about how a C2 should work, and I'd like criticism from people who've actually run C2 in the field. If any of those choices are wrong, I'd rather hear it now. Three things worth reading about 1. Fully Malleable profiles that shape the whole response, not just its envelope. Where most tools shape the wrapper around a fixed payload model, TornadoC2's profile system controls what the response actually looks like, and it does so with one JSON file per profile. A profile declares the three request paths (check-in, tasks, results), the User-Agent with a separate Linux override, extra request headers and per-role request headers, the session cookie name, additional response headers a real server would send, and per-role HTTP status codes for check-in, tasks, results, and error paths.

Showcase: OpenOsoosi (OshoosiClaw) - A 25-crate decentralized Rust EDR mesh with TPM 2.0 attestation, BFT multi-voter consensus, and multi-ring AI agent containment

Hey everyone, I have been building OpenOsoosi (OshoosiClaw), an open-source (Apache-2.0 OR MIT), 25-crate decentralized Endpoint Detection and Response (EDR) agent and AI agent containment mesh written in pure Rust. Most endpoint detection architectures follow a traditional hub-and-spoke model: agents collect telemetry on endpoints and stream it upstream to a centralized SIEM, data lake, or vendor SaaS. While centralized telemetry simplifies aggregation, it introduces well-known structural tradeoffs - single points of failure, ingestion bottlenecks, CGNAT/offline blind spots, and vulnerability to egress severance. Furthermore, with developers and enterprises increasingly running autonomous AI coding and OS agents (MCP servers, local LLMs, CLI agents) with ambient user privileges, traditional signature-based EDRs struggle to distinguish normal developer workflows from prompt-injected agent breakouts. I wanted to explore an alternative design: what would host defense, threat hunting, and AI agent containment look like if endpoints formed a self-healing peer-to-peer security mesh capable of reaching distributed consensus locally without relying on a central cloud controller?

Reverse engineering my own project

i wanted to red-team myself on my project and id like to know how to reverse engineer so i can see what can be done to defend against it. TLDR; i thought my project would have been harder to chew up. it was surprisingly low-effort. my app is aiming to be fully client-side. An implementation in javascript seems like it would relatively easy for an AI to swallow. my latest project is in rust, which would make it harder for a person, but AI can now digest binaries. i created a fairly unique p2p messaging app. a rust-based frontend with a rit-server backend, which can be used to establish a p2p connection. while this version remains close-source, i aimed to create comprehensive technical documentation (formal-verification and security audits too (all ai-slop-maxxing at scale under my guidance)). https://glitr.io https://app.glitr.io a core detail to my project is the focus on client-side cryptography and storage. i think my older iteration as a javascript webapp would be relatively easy for AI, so i thought id put a spin-on-things by having a rust wasm frontend. In practice, i dont think AI broke a sweat. i know nothing about decompiling, but i think the TUI would be the easiest for it
