After 2.5 months in beta, and over 1000 organic users, and a small discord community, I am finally annoucing the launch of https://t.co/OzGP5VPli2 @OpenBinAI
The Free and Opensource collaborative security research and reverse engineering platform. Weather you're into malware analysis, or vulnerability research, you can now create and access your projects anywhere completely for free, share projects with friends and fellow researchers, and publish your analysis reports or vulnerability research publicly with the community!
You can also peer review publicly posted research, fork and make your own revisions, and build your public profile, all with fully build in LLM access to get AI assistance with your work in openbin. This platform was build to address the gap in the security research community where we did not have a collaborative space to work on things together like how developers have github, and github would probably ban you anyways, we don't!
Join us today, a growing ecosystem of enthusiastic, passionate, and collaborative security researchers, completely for free!

🐀 RatCTF is free to start. Not a trial — free.
96 active challenges, and a stack of paths you don't pay for:
→ OSCP Preparation — 9 modules, 19 machines. All 9 modules free.
→ CMWAP Practice — 8 machines, no flags at all. You scope it, plan it, report it, debrief it.
→ Pentest Reporting — 4 modules, PTES-aligned. Free.
→ CPTS Preparation — first module free.
What makes it different once you're in:
🏅 A certificate for every machine you own. Not points, not a streak — a shareable, verifiable cert per box, in Standard, Elite and Legendary tiers. Points aren't on your CV. These are.
🎒 An inventory. Items you pick up carry with you and attach where they're needed.
📝 Real pentest plans and reports, not just flags. You write the deliverable a client would actually read.
📖 Community writeups, bug bounty reports and hints — written by the people hacking the same boxes as you.
Start free, decide later 👇

Authorised targets only, always. Much love <3
@Maskoff023 I think those pentesting certs + SOC certs like SAL1,2 , BTL certs helps you a lot rather than theoretical ones. Sec+ and CISSP does open doors as well.
Document everything you learn in cybersecurity.
And no, I don't mean post everything on X.
Documentation means keeping a record of what you learn, what you do, what works, what fails, and what you discover.
Finished a lab? Document:
• What was the problem?
• What did you investigate?
• Which tools or commands did you use?
• What did you find?
• What confused you?
• What mistake did you make?
• How did you solve it?
• What did you learn?
Keep notes in Notion, Obsidian, OneNote, Google Docs, Markdown files, or anywhere you can easily return to.
Build your own personal cybersecurity knowledge base.
Your Linux commands.
Your networking notes.
Your SOC investigation process.
Your SIEM queries.
Your incident findings.
Your lab walkthroughs.
Your mistakes and lessons.
Because 6 months from now, you will forget things.
And when you're trying to revise, solve a similar problem, or explain something to someone else, those notes become incredibly valuable.
Blogging and posting on X can help too. Teaching others is a great way to solidify knowledge.
But don't document for the internet.
Document for yourself first.
One day, you'll realize you've built a library of everything you've learned on your cybersecurity journey.
That is powerful.
Hi, I’m John! I’m a L7 Senior Staff software engineer at Meta.
My weird hobby is making AI Tech content on YouTube and Substack and I wanted to start sharing more here.
In the past I’ve worked on Reels, Meta AI on Msgr and currently working on Threads.
I also teach Agentic Coding with @bytebytego for fun on the side.
Doing an AMA here to share and meet new people. 👋
I work at GitHub. yesterday was rough and i'm not pretending otherwise. full root cause report is up if you want the timeline and numbers, and what we are doing to prevent this from happening again.

Telegram has applied for the .gram domain zone.
If the application is approved by ICANN, a billion Telegram users could get their own second-level domains — yourname.gram.
Users would be able to set up their interactive websites hosted by Telegram — with one prompt ✨
Detection engineers don't want you to know this one trick
