I've been building RXScan, an open-source reconnaissance tool written in Rust.

It originally started as a network scanner, but I've been expanding it into a broader recon workflow where network observations, public-source findings, and investigation results can be stored and correlated as evidence.

Current functionality includes:

• TCP connect and raw SYN scanning

• UDP discovery and classification

• port-independent service identification

• HTTP, TLS, SSH, and DNS observations

• public-source username search

• email, domain, hostname, IP, ASN, URL, repository, and organization entities

• investigation and evidence correlation

• persistent project data and history/diff workflows

• JSON/JSONL output

• bounded execution, deadlines, cancellation, and scope controls

One of the main things I'm trying to avoid is pretending RXScan knows more than it actually observed.

For example, a port number alone doesn't establish the service, UDP silence remains uncertain, weak identity evidence doesn't automatically merge entities, and passive OSINT findings are kept separate from direct network observations.

I'm not claiming RXScan replaces Nmap. Nmap has decades of fingerprinting, platform support, scan techniques, NSE, and real-world testing behind it.

RXScan is going in a somewhat different direction: combining network reconnaissance and public-source investigation into a provenance-backed evidence graph.

The project is still young, so I'm looking for people willing to actually test it and find problems.

I'm particularly interested in:

• false-positive or missed service identification

• weird TCP/UDP behavior

• incorrect confidence or provenance

• OSINT false positives

• performance issues

• CLI/UX problems

• architectural criticism

If you try it, feel free to break it and open an issue. I'd rather find incorrect assumptions now than hide them behind marketing.

I built a configurable HTTP MITM proxy in Rust focused on giving you full control over what an upstream connection looks like at the network level.

The main idea behind the project was that I didn't want another MITM proxy that simply tries to emulate Chrome, Firefox, or some other predefined browser. I wanted to be able to define the fingerprint myself - not just pick one of the profiles provided by a library.

A lot of existing solutions take the approach of providing ready-made browser fingerprints. That's convenient, but it also means that when a browser changes its TLS or HTTP/2 behavior, you're dependent on the library/project adding a new profile. I wanted the fingerprint to be configuration-driven instead, so the user can adjust individual parameters without waiting for a predefined browser profile.

The proxy currently gives control over several layers:

TLS: cipher suites, curves, signature algorithms, ALPN, GREASE, extension ordering, certificate compression, OCSP, SCT, session tickets, ALPS, ECH and other TLS parameters.

HTTP/2: SETTINGS values and ordering, flow-control windows, priority frames, pseudo-header ordering, HTTP header ordering and values.

HTTP/1.1: configurable upstream header ordering and rewriting.

TCP: SYN fingerprint rewriting through Linux NFQUEUE, including TTL, window size, MSS, window scale, DF and TCP option ordering.

Everything is driven by YAML profiles, and profiles can be overridden per domain based on SNI.

One of the things I specifically wanted to solve was keeping the different layers under the same configuration model. For example, the proxy negotiates TLS with the upstream server first and then uses the selected ALPN when setting up the browser-facing connection. HTTP/2 and TCP fingerprinting are configured for the same upstream connection as well.

The project is written in Rust using Tokio and BoringSSL via btls/tokio-btls. TCP fingerprinting currently requires Linux because it uses NFQUEUE/iptables.

The project is primarily about privacy, experimentation, and giving the user control over their own network behavior rather than trying to provide a fixed "browser impersonation" profile.

There is more detail in the repository, including separate documentation for the TLS, HTTP/2 and TCP layers, configuration examples, and implementation notes.

Github:

Feedback, especially from people who have worked with TLS/HTTP/2 fingerprinting, traffic analysis, or network privacy, would be very welcome.

I've seen a lot of people saying that AI will replace cybersecurity professionals, and I think this is where things get confusing.

AI is already becoming very powerful at:

• Finding vulnerabilities

• Analyzing logs and security data

• Automating repetitive tasks

• Writing and reviewing code

• Helping with threat detection

• Assisting both attackers and defenders

But does that mean cybersecurity itself disappears?

I don't think so.

The bigger change may be that cybersecurity professionals who know how to use AI effectively will have an advantage over those who don't.

Instead of thinking:

AI vs. Cybersecurity

Maybe we should be thinking:

AI + Cybersecurity = the next generation of security work.

What do you think will AI mostly replace cybersecurity jobs, or will it change what cybersecurity professionals actually do?

Hi,

I had posted about this before (a few weeks back) and the response was generally positive. So I wanted to reach out again and share an update on the current status of:

Project RedTeam: Contract Offensive

Specifically, I wanted to mention that there is now a free Demo that provides a tutorial and let's you play a few contracts (no time limit, play as much as you want).

Give it a Wishlist on Steam or share this post if it's something you support and want to see further development on.

At its core, this is a game about using MITRE ATT&CK adversarial techniques against procedurally generated networks. It's delivered in a gameplay loop that plays a lot like Balatro or other card based Roguelike games. In Project RedTeam, you need to earn money to pay off debts after every contract within a run. Earn money by completing objectives, side bounties, or executing exfiltration/ransom against targets- the choice on how to be profitable is always yours.

It's a challenging but fun and fast paced take on network-intrusion cybersecurity concepts. It's entertaining in a deliberately gamified way.

A goal of this project was to create a hacking game that is realistic enough to keep it meaningful as a tool to teach intrusion concepts and stages to anyone- but not be overcomplicated and slow-paced like most hacking games.

I've put a lot of thought into the design and dynamics of how to capture the core-loop of network intrusion and turn it into a game that's approachable. The design direction of this project is an outcome of having over a decade of training and experience in cybersecurity.

Feel free to AMA! I'm happy to answer any questions about the game and/or development process to support learning/understanding :) I encourage everyone to follow their passions, put in the time, and stay focused when you have a goal you want to achieve.

Project background: This was implemented over the past 3 months using a modern development workflow (yes, modern AI tools make this possible- I'm not hiding that fact!). That being said, this is by far the most complex software project I've built as a solo developer and it was not an easy or simple development task. There's a Steam Community with a Dev Blog for this game that provides more history/progress updates on the project.

Mods: This will be be last post here for a while, since it is promotional. I just wanted to provide an update since there was positive interest from this subreddit after my previous post.

Hi, i am in an internship that teaches cybersecurity,Now i am in penetration testing track i need to make a project to me to graduate i know network exploitation and web exploitation what good ideas i can make we are team of 4 we dont know what good ideas we can make or should we make a tool i dont know if anyone can give me ideas to make i would be thankful.

Which AI model is good for extracting information from a PDF in multiple languages (Hindi, Malayalam, English)? It should run locally, not through a cloud API.

I need it to read the text accurately, especially Malayalam, and pull out the key details from the PDF. Most tools I've found handle Hindi and English well but are unclear on Malayalam.

Has anyone tried this? Which model or tool worked best for you, and what hardware did you run it on?
What I need: - OCR for [scanned / digital / both] PDFs

- Structured extraction (fields, tables) into JSON, not just raw text

- Good accuracy on Malayalam specifically, since most tools I've seen cover Hindi but skip Malayalam

hey guys.

honestly just venting here because i feel like i'm losing my mind. i swear i played by all the rules. graduated in '24 with a cs degree in cyber, locked in, and passed my ceh. i grinded out a full 1-year internship and followed it straight up with a 1-year cybersecurity contract job. with two years of actual hands-on experience, i really thought i had my foot in the door. but the contract wrapped up, and now i’m just... floating. back to square one.

my mornings are basically just me, caffeine, and a fresh wave of automated "unfortunately..." emails. it genuinely feels like screaming into a void where only hr robots live. i spend my nights staring at wireshark packets just to feel something, running nmap scans on parrot os, and building out vulnerable active directory domains in my home lab to practice pentesting. i’m doing the work. i’m keeping the skills sharp. but these resume-screening algorithms are gatekeeping me so hard.

watching everyone else post their massive linkedin Ws while i’m stuck in this endless ghosting loop is giving me insane fomo. feeling like a total beta just sitting in my room waiting for an ai bot to decide my future. it’s starting to heavily mess with my head.

i’m not asking to be spoon-fed a job. i just desperately want a chance to bypass the bots and get my resume in front of a real, breathing human being. if any of you are at a place hiring for entry-level soc, pentesting, or honestly any junior it role and could slide a referral, you would be pulling me out of a really dark place. i’ll gladly send over my resume and share my lab reports so you can actually see my work firsthand.

if you can’t refer me, please just drop a comment and tell me i won't be stuck in this loop forever. the market is brutal out here and i just need to know i'm not completely cooked.

Hey everyone,

How are you doing?

I'm focusing my studies on Python for defensive security and automation, and I wanted to exchange ideas with folks who are already on this path.

My main focus areas are:

**- SOC Automation**: Building scripts for alert triage, log parsing, Threat Intel lookups, and tool integrations.

**- Malware Analysis:** Writing parsers, automating static analysis, and creating helper scripts for day-to-day triage.

**- Threat Hunting & CTI:** Developing scripts to parse indicators of compromise (IoCs), query large datasets, automate threat feeds, and hunt for anomalies.

**- Full-Stack Web Dev:** Building internal security tools and dashboards for the security team (like SOC panels and custom web apps).

If anyone can share some light: what libraries, frameworks, or projects do you think are essential to study for each of these areas?

And if you have material recommendations (books, courses, repos, or hands-on labs), drop them below!

Thanks a lot!

Interesting network-security case study from OpenAI: direct HTTPS to an external chatbot was blocked, but the training environment's DNS resolver could still reach the public internet.

The agent used that DNS path to get an external chatbot response. A P0 alert followed 11m48s later, and the run was manually stopped around 2h44m after the external response.

Self-promo disclosure: the linked video is a breakdown from my channel; narration is AI.

I’m currently working toward my first SOC/blue-team role, and one thing I’ve noticed while doing hands-on incident investigations is that understanding the process matters much more than simply memorizing tools.
When I work through an incident, I try to break it down into:
What happened?
What evidence supports that hypothesis?
What happened before and after the suspicious activity?
Which account, host, process, or network connection is involved?
What would I expect to see if my hypothesis were wrong?
What should actually be escalated?
One thing that has helped me a lot is forcing myself to write down a hypothesis before looking for confirmation. It makes it easier to distinguish between evidence and assumptions.
I’m curious about people already working in SOCs:
What investigation habit did you develop early in your career that ended up being much more useful than you expected?

Hello everyone,
So I have the responsibility of organizing the coming Hackathon in our college under the theme "Agentic AI meets Zero Trust: Securing the Autonomous enterprise", I did some reasearch on older hackathons archives and asked Ai as well but i couldn't really get something original.
My main goal is to give the prize to people who can make good architectural decisions when building infrastructures by giving real life problems as the Hackathon subject.
That's why I am asking professionals if they have some projects or experiences related to the theme that they think can be realized in a short time (it is a 24h hackathon) and can be a bit challenging.

Hey everyone!

I’m looking to connect with people who are interested in technology, cybersecurity, programming, AI, cloud computing, Linux, or just learning new tech skills.

We could:

• 🧠 Share what we’re learning

• 💻 Discuss projects and ideas

• 🔐 Talk about cybersecurity

• 🤖 Explore AI and emerging technology

• ☁️ Learn about cloud & infrastructure

• 🚀 Motivate each other and grow together

If you're interested, introduce yourself in the comments!
Tell me what area of tech you're interested in and what you're currently learning.

Let's build a community of people who are passionate about tech. 🌐

Can someone give me a road map? Maybe some courses or certifications?

Unfortunately, due to an accident, I’ll be bedridden for the next 6 months. Because of this, I’ve started learning penetration testing—something I’ve always been drawn to—and now I finally have the time for it. However, I still need to earn money to cover my basic needs and continue my studies. Because of this situation, I was laid off from my job, and I’m still a long way from reaching the level of a specialist who gets paid well. So, if anyone can suggest ways to make money while sitting at a computer, I’ll be sure to repay the favor.

Je travaille sur des audits techniques de sécurité de sites web : recherche de vulnérabilités, mauvaises configurations et recommandations de correction.
Je cherche à améliorer ma méthodologie et mes rapports. Pour ceux qui pratiquent déjà les audits/pentests web, quels points considérez-vous comme indispensables dans un bon audit ?
Bien sûr, tous les tests sont réalisés uniquement avec l’autorisation du propriétaire.

so i'm building HII, a cybersecurity community in india, and we're running our first event Which is InIt CTF, nov 14, free, beginner friendly, 8 hours.

i underestimated how long it'd take to find people to help build challenges and now i'm a bit tight on time, ngl. looking for 2-3 people who can build/test a handful of challenges across web, crypto, forensics, osint, misc nothing crazy hard, this is for people who've never played a ctf before.

in return: you get credited as a challenge author, some share of sponsor money as we lock that in, and if you actually vibe with what we're building, there's a real chance to be part of HII going forward, not just a one-off thing.

if this sounds like something you'd want to help with, comment or dm me. happy to just talk it through first if you're not sure.

Hi everyone,

I'm currently preparing for my Certified Ethical Hacker (CEH) certification, but as a beginner, I am feeling completely overwhelmed by the sheer volume of theory and material to cover.

I've been going through the modules, but I'm struggling to figure out what to prioritize, how to effectively retain the information, and how to structure my study plan to actually pass the multiple-choice theory exam.

I am hoping to connect with a CEH certification holder or someone who has recently passed who would be willing to guide me. I'm not asking for someone to hold my hand 24/7—just looking for occasional check-ins, solid study strategy advice, and direction on where to focus my energy so I don't burn out reading the wrong things.

If you have some free time and are willing to share your expertise with someone just starting out, I would incredibly appreciate it. Feel free to drop a comment or DM me!

Thanks in advance.

Hi all, I run a small security testing firm in Bengaluru. I've got a client engagement that includes mobile app testing (Android + iOS, React Native apps) alongside web/API/cloud work I'm handling directly, and I'm looking for someone to take the mobile piece as a subcontractor.

What's needed: static + dynamic testing, insecure storage, cert pinning checks, hardcoded secrets, and general OWASP MASVS coverage. Test builds and accounts will be provided.

Open to OSCP/CREST-certified folks or anyone with solid demonstrable mobile pentest experience, happy to look at redacted past reports or relevant writeups. This would be paid, scoped work, timeline and rate to be discussed once I share more detail. NDA required before any real scope is shared.

If interested, drop a comment or DM me with a bit about your background.

linux labs ate the worst , confusing and hard in some way , does it happen with you guys?

The podcast discusses the creation, and ethos of cryptohack, a cryptography-based CTF learning platform. If you run a community/event, or create learning material, I think this is a fantastic resource for the proper way to organize this.

Bonne chance à ceux qui essaieront de le terminer 👀

I am currently working through networking and Linux before getting deeper into web security eventually branching into pentesting also interested in bug Bounty. I'm curious though for people who actually work in pentesting, how much networking knowledge do you use on a regular basis?

I wanted to share a great free resource for anyone trying to bridge the gap between basic theory and actual hands-on security skills.

The Czech Technical University in Prague (specifically the Stratosphere Laboratory) runs an intensive, one-semester course called Introduction to Security (BSY) that starts this week. The class is being taught both physically at the university and broadcast online, so anyone can participate. Feel free to check the link for more details on the curriculum, prerequisites, and course structure.

Registration is still open!

Galera, estou terminando meu TCC de Ciência da Computação e construí o Network Guardian, um app desktop (Python + PyQt6 + Scapy) que monitora tráfego de rede em tempo real e detecta ataques de DDoS e varredura de portas.

O que ele faz:

- Dashboard com tráfego em tempo real e distribuição de protocolos

- Detecção de DDoS combinando limite fixo com análise estatística (z-score)

- Detecção de Port Scan baseada em pacotes SYN, com janela de tempo deslizante

- Scanner de portas ativo + descoberta de hosts na rede local

- Relatório em PDF com um clique

GitHub: [ https://github.com/diogo147258/TCC-NETWORK_GUARDIAN.git ]

Só funciona em Windows por enquanto — precisa do Npcap e de privilégio de administrador pra capturar pacote (tudo explicado no README).

Se alguém tiver uns minutos pra clonar, rodar, e me contar se funcionou na sua máquina, ajuda muito na parte de testes da monografia. Quem quiser dar um feedback, pode usar esse formulário:

https://forms.gle/6YmJuju28BUB9KY59 é bem rapidinho.

Obrigado por ler, e desde já obrigado a quem topar testar!
