I built a free learning platform because I was tired of scattered, paywalled resources. Now I need help keeping it alive.

So a while back I got frustrated (classic developer origin story, I know). Every time I wanted to learn something new — a language, a CS concept — I'd end up bouncing between five different sites, half of them behind paywalls, none of them …

I built a free learning platform because I was tired of scattered, paywalled resources.

Asset-Inventar prüfen & Upstream-Advisory überwachen

So I built my own thing: Learn by Play → https://learn-by-play-dusky.vercel.app/

Right now it has two kinds of content:

Language learning — real spoken languages, and I'm currently adding voice audio so people can actually hear pronunciation instead of just reading text and guessing

Programming roadmaps — clear paths for frontend, backend, algorithms, and data structures, starting with JavaScript (more languages coming, don't worry haha)

The idea is simple: give people an honest, structured path to actually understand things, not just skim through content and forget it a week later.

Right now it's just me, building this on my own time, nights and weekends. It works, it's live, people can use it today. But I'd love for it to grow into something bigger, and that's a lot harder to pull off solo.

If any of this resonates, here's how you can help:

🛠️ Know frontend, backend, or content design? I'd genuinely love a collaborator.

☕ Want to support the project directly? The link is down below.

💬 Just curious or have ideas? DM me; I read everything, I promise.

PD: If you try it out and hit a bug or something feels off, please tell me; I'll fix it as soon as I can :)

This started as a personal frustration. I'd like it to become something a lot of people find genuinely useful.

SOC Incident Playbook: Remote Code Execution (RCE) Defense

WAF MitigationSofort

Virtuelles Patchen am Reverse Proxy / WAF für gefährdete URL-Pfade und Payloads aktivieren.

SecRule REQUEST_URI "@rx ..." "id:1001,phase:1,deny,status:403"

Web Shell ScanSofort

Web-Root auf neu angelegte Scripts, anomal modifizierte Dateien und Persistence scannen.

find /var/www -type f -name "*.php" -mmin -120

Outbound FilteringSofort

Ausgehenden Datenverkehr (Reverse Shells zu unbekannten IPs/Ports) blockieren.

ss -tunp | grep -E ":(4444|1337|8080|9001)"

Vendor Patching

Hersteller-Update in Staging validieren und schnellstmöglich in Produktion ausrollen.

apt update && apt --only-upgrade install <pkg>

Fokus-Vektor:

Kognitive Analyse für identifizierte Bedrohung: Erhöhte Bedrohungslage im Bereich I built a free learning platform because.... Basierend auf 368k Vektor-Korrelationen werden sofortige Isolationsmaßnahmen für betroffene Endpunkte empfohlen.

🛡️ Angriffsfläche & Exposure

Netzwerk/Remote-Zugriff ohne Vorauthentifizierung möglich.

⚡ Empfohlene Sofortmaßnahmen

1. Perimeter-Inspektion: Relevante Portfreigaben und exponierte Endpunkte unverzüglich scannen.
2. Patch-Applikation: Hersteller-Hotfix einspielen oder betroffene Daemons in isolierte DMZ-Segmente überführen.
3. Telemetrie & EDR-Alerts: Prozessaufrufe und Child-Processes auf anomale Shell-Spawns überwachen.
