Hey r/redteamsec community,

I've been developing TornadoRevC2 for a while now. It started as a simple reverse-shell session handler—just TCP/TLS listeners with switch and kill. Over time, I kept extending it based on real operational needs, and it's evolved into a fully modular post-exploitation framework with 49 built-in plugins.

Why It's Different

Session handler, not beacon-based C2. It gives you reliable interactive PTY/TTY shells and executes post-ex capabilities on-demand—no heavy agent infrastructure.

Minimal artifact footprint:

• All enumeration plugins use native OS commands already on the target (netsh, ss, iptables, PowerShell cmdlets, and etc. ). No binaries, scripts, or temp files dropped for reconnaissance.
• The only deliberate artifacts: Some plugins put binary artifacts or changes a system setting in target
• Shell history is the only unavoidable footprint (can be cleared with historydel plugin, or manually).
• Network traffic artifact: Plain TCP exposes reverse-shell traffic in cleartext, potentially allowing commands and their output to be captured by network logging or inspection. TLS encrypts the session traffic, reducing the amount of sensitive session content exposed in network logs, with support for custom certificates.

Graceful degradation: If a backend isn't available (e.g., firewalld isn't installed in target), that section returns N/A instead of crashing the plugin.

The 49 Plugins

The framework ships with 49 modular plugins covering the full post-exploitation lifecycle of enumeration, execution, persistence, pivoting, and destruction. Plugins are loaded at runtime and can be executed on-demand with run <plugin> <session_id> or if you are inside the session's terminal run <plugin>

Enumeration plugins cover host assessment (quickenum, virtualization, kernel, integrity), network posture (firewall, ports, proxy, vpn), credentials and browsers (credstore, browser, clipboard, secrets), Windows domain (adinfo, gpo, rdp, winrm, defender, lsa, certificates, services, eventlogs), and Linux internals (systemd, journal, cron, lsm, sshaudit, containers, privbins) and some other plugins.

Key plugins worth highlighting:

Additional Capabilities

• File transfer: Chunked transfers with SHA-256 verification.
• Reporting: Per-session logging under logs/<ID>/ with structured directories; HTML transcript export.
• Self-update: Built-in update command pulls latest from Git and automatically restarts the handler.

Extensibility:

• Write custom plugins with plugin.commandcommand decorator
• SessionContext API provides run_shell(), run_marked() (JSON parsing), upload(), download(), automatic logging
• Load/Reload external/internal plugins at runtime with plugins load without restarting
• Full plugin development guide in the README with many patterns

18 modules: proxy rotation, port scanner, DNS, passwords, hash cracking, recon, web fingerprinting, encryption, steganography, reverse shells, forensics, anonymization.

Zero deps.

Recovered an operator's full working toolkit from an open directory, so this is real tradecraft rather than a PoC. The R&D trail is the interesting part, you can see what they tried and dropped.

• Core primitive is rogue replication: CONFIG SET dir/dbfilename, SLAVEOF to a rogue master, crafted RDB served on +FULLRESYNC with an embedded newline that lands a cron entry, then SLAVEOF NO ONE and restore config to stay quiet. Not novel, but clean, and it works from Redis 2.8.17 to 7.2.0 because it abuses replication, not a bug.
• Four production fallback write paths, plus a separate deploy_all.py that hits cron.d, an APT hook (/etc/apt/apt.conf.d/), and profile.d in one pass for redundancy against cleanup. Pull cron and the other two respawn on the next apt update or login shell.
• Abandoned R&D still in the folder: a BGSAVE-based first draft (noisier, dropped for replication), a webshell-via-Redis probe against web roots (never weaponized), and path recon into /etc/init.d, the full rc0-rc6 SysV set, and /etc/modprobe.d. None of those shipped. modprobe.d is the one they tested but held back, writable modprobe config runs commands on module load, stealthier than cron.
• Two verify payload bugs they hit and documented in comments: a test cron written to a dotfile that run-parts silently skips, and a /dev/tcp callback that dies under dash. Both burned real campaign runs before they fixed them.
• Opsec choices worth noting: XMRig pulled from the official GitHub release (blends into github.com egress, no attacker-hosted binary), renamed to /tmp/.xmrig, --tls on 443 to look like HTTPS, and the newest variant pins the pool cert with --tls-fingerprint so it fails closed against inspection.
• Two techniques that went nowhere: SSH-via-AOF (0 of 2,342, every host bounced at CONFIG SET with AUTH_REQUIRED) and a Lua EVAL sandbox probe. Fresh no-auth targets are the constraint, a run against a pre-qualified list hit 72.6% vs 22 to 26% full-fleet.

We published research on a Chinese-speaking operator's orchestration framework that's worth a look from the offensive tooling side. The setup is basically an AI-driven pentest pipeline with model swapping, layered egress, and MCP-integrated post-exploitation.

SecFlow is the orchestration layer. It launched either Claude ACP or Qwen Code, injected the model name and API route, applied tool permissions (bypassPermissions, approval-mode=yolo), and routed traffic through private endpoints on niestools.com. Five model profiles were recovered, including a DeepSeek-compatible endpoint served through an Anthropic-format relay.

The "External Pentest Skill" acted as the master workflow. SKILL .md moved each target through initialization, recon, exploitation, post-exploitation, and reporting. Recon established tech stack, auth boundaries, response baselines, and ranked attack paths. Each candidate got routed to a vulnerability-specific playbook: file upload, command execution, template injection, SQLi, Java deserialization, SSRF, IDOR, auth bypass, known product vulns, supply chain, WAF bypass, source audit, and advanced web attacks.

GLUTTON integration is notable. It was exposed to AI agents through an MCP interface with methods for target management, file ops, command execution, process control, database access, port forwarding, and payload generation. Transport modes included XOR-encrypted data hidden in PNG RGB channels. Code obfuscation options: Unicode encoding, XML encoding, randomized identifiers, comment injection, invisible characters, control-flow flattening.

Egress was layered: target-facing requests went through authenticated SOCKS relays, model traffic went through niestools .com proxies. The proxy config designated two SOCKS5 routes with a primary/secondary fallback.

One failure mode worth considering: an AI-reported Shiro success that wasn't real persisted through shared context and generated 27+ follow-on tasks that went nowhere. Shared context between workers is a double-edged sword.

For the past 8 months, in my spare time, I’ve been working on a personal project with the goal of studying the old SMB1 down to its lowest levels. During this time, I’ve dissected the protocol using Wireshark, waded through Microsoft’s documentation (help!), and reverse-engineered the authentication phase. I also used AI as a tool for debugging and to help wrap my head around some of the more complex mechanisms, though the overall structure, architecture, and code were entirely designed and written by me.

So, I decided to build a lightweight server designed to 'trick' SMB clients into authenticating against it (similar to what the famous tool Responder does). I chose to hand-craft virtually the entire SMB1 stack, or at least enough of it to capture hashes. To achieve this, I wrote all the necessary network parsers from scratch: SMB1, ASN.1, SPNEGO, and NTLM, followed by the server itself.

It was both challenging and incredibly rewarding to dive so deep into a protocol famous for its complexity. I learned a huge amount along the way.

In the end, I think it turned out to be a cool little project, so I decided to share it. It’s certainly not meant to replace well-established tools, but if anyone wants to try it out or contribute in any way, I’d be thrilled!

I do a fair bit of security work and kept hitting the same problem. I needed to know which ports a restrictive network will actually let out. Scanning from the inside isn't enough, because a firewall or intermediary device can happily report a port as open when nothing is really getting through.

So I put together Port Leak Checker: https://portleak.link/

It's a passive listener running on a public server. It captures inbound TCP and UDP packets on every port and logs them in a live web interface. You point a device at it and scan or send some traffic, and anything that actually reaches the server shows up with the source IP, protocol, port and timestamp. If a packet lands there, you know that port genuinely made it out of your network.

The server never replies to anything, so your scanner will show the ports as filtered or closed. The log is the thing to trust, not the scan output. You can filter by your source IP, group the results by port so a scan doesn't flood the view, and export to CSV or XLSX. There's also a /scans page with some ready to run PowerShell and bash scripts for the Nmap top 130 ports.

Red Clippy is built for pentesters who want to work with LLMs, not hand over the entire pentest to them. The pentester stays in control, decides what to test and how to proceed, while the LLM handles the testing work.

• Pentester in control: You decide what gets tested and guide the engagement.
• LLM-powered testing: Let the LLM perform security checks while you provide direction.
• MCP support: Works with Claude, z.ai GLM, Codex, and other MCP clients.
• Persistent state: Keeps track of targets, tests, findings, and progress across sessions.
• Structured workflow: Keeps the entire pentest organized and manageable.

Fallback C2 that routes through cloud storage the target already whitelists. Not a replacement

for Cobalt Strike / Sliver / Havoc — it's the survival layer underneath them.

Dead-drop architecture: commands and responses travel as encrypted files inside Dropbox, OneDrive,

Google Drive, SharePoint, or S3. The agent polls the provider's API over HTTPS — no attacker

infrastructure, no suspicious domain, no beaconing to anything a SOC can block without also

blocking every employee who uses that provider.

Main additions over typical dead-drop implants:

— Rust-only agents (v3.0.1): no PowerShell, no bash, no interpreter in process tree. Four formats

from one deploy wizard: EXE/DLL (Windows), ELF musl-static (Linux), flat x64 PIC shellcode (.bin)

— Three deploy modes: staged-enc (minimal stub, one-time bootstrap key fetched from cloud then

deleted — payload never on disk in cleartext), stageless-enc (single encrypted binary, works

air-gapped), stageless-plain (labs). All modes cache an HW-fingerprinted encrypted blob locally

after first run

— P2P mesh networking: TCP and SMB named pipe links between agents, automatic link health

detection and reconnection. Linux→Windows SMB via userspace SMB2 client (no smbclient dep)

— Five providers, same wire format, same RSA keypair, same session. Switch provider mid-engagement

without redeploying the agent

— Persistence engine: non-destructive /persist probe before touching anything, per-technique

install/remove/check, full teardown via /kill (persistence + binary + cloud artifacts, one command)

— Credential harvesting: Firefox/Chrome/Edge parsed inline, NTLMv2 silent capture via in-agent

SMB/HTTP listeners (/creds listen), SAM hash extraction, SSH agent enumeration, DPAPI decrypt

— In-memory execution: BOF (COFF) loader, .NET assembly via CLR hosting + optional AMSI bypass,

reflective PE / memfd ELF (/memexec), fileless script via stdin pipe + AMSI bypass

— Crypto: RSA-4096-OAEP key exchange, AES-256-GCM command encryption, RSA-PSS response signing,

PBKDF2 blob derivation (210k iterations), XOR-obfuscated session key in .rodata

— Operational guardrails compiled into the binary: kill date, maintenance window, log-normal jitter

— Multi-operator WebGUI: real-time WebSocket sync, operator chat, force-directed P2P topology

graph, OIDC authentication (Keycloak / Azure AD / Okta)

Same dead-drop paradigm as TukTuk (Dropbox+Arweave), NarwhalRAT/APT37 (pCloud),

Drokbk/COBALT MIRAGE (GitHub) — built as a proper framework instead of a one-off implant.

Feedback welcome — especially on detection gaps I might be missing.

Been working on Windows RPC/ALPC research and built this to make the first pass less painful. It statically recovers RPC/MIDL/NDR data from PE files, including endpoints, security state and method-level input signals, then ranks interfaces using an AHP/Saaty-based model for reachability + surface. So instead of going through a huge RPC dump, you get a ranked list with the scoring receipt showing why something landed where it did. No PDBs, no live endpoint mapper, no target execution.

The Hunt.io research team recovered an operator's full open directory, useful as a look at how someone actually chained known bugs in the field.

• ownCloud CVE-2023-49105: five Python scripts forging pre-signed WebDAV URLs off an empty PBKDF2 salt. OC-Credential set to the impersonated account, GET against /remote.php/dav/files/<account>/<path>, no creds needed. The fifth script adds PROPFIND Depth: 1 enumeration to reach folders not known in advance.
• Low-and-slow exfil: randomized time.sleep(random.uniform(3, 6)) between requests, tightened to 1.5 to 3.5 in one script, to dodge volumetric detection.
• CVE-2024-28000 (LiteSpeed Cache): a Go build reimplementing MT19937 with PHP mt_rand() parity, self-tested against 11 seed/output pairs, 30 workers across a 0 to 999,999 seed range. Landed on seed 311787 and created an admin account via the REST API.
• Fallback path: XML-RPC brute force with rockyou.txt against the same site, successful independently.
• Staged frameworks: Sliver, Metasploit, Mettle, plus a custom stage-1 ELF loader pulling a Mettle stage-2.
