💡 Decimen: Transferă fișiere prin lumină, fără rețea, Wi-Fi sau Bluetooth!Dacă ai nevoie să muți date rapid între două dispozitive izolate (air-gapped) fără a folosi rețele, cabluri sau stick-uri USB, Decimen propune un concept ingenios: transferul optic direct de la ecran la cameră.✨ Cum funcționează și ce oferă Decimen:🔦 Transfer optic ecran-la-cameră:• Transforma datele în modele vizuale de mare viteză pe ecranul dispozitivului emițător, care sunt ulterior citite și decodate instant de camera dispozitivului receptor.🛡️ Securitate maximă pentru sisteme izolate (Air-Gap):• Nu necesită conexiune la internet, local Wi-Fi, Bluetooth sau conturi. Oferă o metodă excelentă de transfer de date către sau dinspre medii de rețea strict securizate.📄 Suport pentru fișiere și text:• Permite transmiterea fișierelor de până la 64 MB sau a blocurilor de text de până la 4 MB (cu compresie automată atunci când este posibil).⚡ Fără instalare sau Asociere (Zero-Pairing):• Elimină complet procesul complicat de asociere Bluetooth sau configurare de rețea. Totul se rezumă la: deschizi aplicația, îndrepți camera spre ecran și primești fișierul.💻 Punte între platforme și dispozitive:• Funcționează ca o soluție universală pentru transfer direct între telefoane, tablete și PC-uri, indiferent de sistemul de operare utilizat.O abordare inovatoare și extrem de utilă pentru intimitate, securitate cibernetică și transfer rapid de date fără infrastructură! 🚀#Decimen #CyberSecurity #AirGap #OpenSource #TechNews #Privacy #OpticalData #DataTransfer #FOSS

Keyboard Lights As An Airgap Attack Vector

Heard #Ukraine does not have the #digitalSovereignty problems the EU does including dependencies on foreign providers, and certainly innovates, so certainly these things can happen in Europe. Is this true? Does Ukraine have its own search, operating system, cloud, logistics? Or do they #airGap well?

🧪 A new research-backed air-gap leak method, “TrojPix,” shows how malware can exfiltrate data from fully offline systems by imperceptibly modulating on-screen pixels—so copper video cables radiate signals decodable up to 8.1 Mbps in lab tests. 🔎⚠️ https://thehackernews.com/2026/07/new-trojpix-attack-leaks-data-from-air.html #cybersecurity #infosec #airgap #malware

🐛 Air-Gapped-Systeme gelten als besonders sicher – doch Forscher der Shandong University zeigen mit „Trojpix“ eine leistungsfähige Datenausleitung über Monitorkabel: Malware nutzt Monitorsignale zur Funkübertragung. In Tests bis zu 8,1 Mbps & Reichweiten bis 208 m. ⚠️ https://www.golem.de/news/air-gapped-systeme-malware-leitet-daten-ueber-monitorkabel-aus-2607-210592.html #CyberSecurity #Malware #AirGap #Infosec #ITSecurity

@miffyhelen my freezer even has artificial intelligence written on the front. Maybe time to dust off my sad server song.

Air gaps don't stop sound.

USAT (Ultrasonic Sub-Audible Trojan) — acoustic covert channel operating at 17–22kHz, inaudible, cross-device, no physical access required.

Последний рубеж: почему ленточная библиотека — это самый надёжный «холодный кошелёк» для данных В 2025 году мировые потери от киберпреступности, по оценкам отраслевых аналитиков, превысили один триллион долларов США — "это ж сколько стран можно было прокормить?!". В подавляющем большинстве случаев речь идёт об атаках программ-вымогателей. И в каждом таком инциденте рано или поздно возникает один и тот же вопрос: существует ли копия данных, до которой злоумышленник не сможет добраться?

Anyone running local AI or storing private data should stick to an air-gapped system. Why?

Corporations & governments harvest enormous amounts of data to predict your behavior.

For local updates, I still advise what I told companies 25+ years ago:
Use USB drives for one-way updates only. Never reuse them, destroy after a single use. Modern research shows even USBs can carry spyware, so treat each drive as potentially contaminated & enforce strict, one-time procedures.

One-Way Data Extraction For Logging On Airgapped Systems https://hackaday.com/2025/11/27/one-way-data-extraction-for-logging-on-airgapped-systems/ #airgappedsystem #SecurityHacks #optocoupler #raspberrypi #airgapped #airgap #light #led

If you're interested in the current state of global #infrastructure #security, just take a look at @vncresolver

Spoiler: We're fucked. What the hell happened to #airgap?

@mayahustle Attacks against infrastructure in general are worrying. We definitely do not need anyone deploying "Stuxnet V2" or similar against national infrastructure.

This is why some things need to remain off-line. Not every needs to be connected.

In case anyone wants to run their own #LLM on their personal devices, I can suggest #lmstudio It allows you to download any major model that's out there to your own laptop/desktop, and then you can use it's Graphical Interface to interact with it in a familiar interface environment, as you would #Claude or #ChatGPT or #Gemini. It will also let you know if your device has enough resources (power) to run a specific model variant: https://lmstudio.ai/

For those of you who love the Terminal (aka: Command Line Interface or #CLI), check out https://ollama.com/

For starters, I suggest the #gemma3n model (works great on tablets, laptops, or phones), or #llama3.1 for the most common interactions. While most of us geeks will have very powerful personal systems, or servers in our home racks, most people do not have high-end systems/devices. The gemma3n model is lightweight, very powerful, and a solid general purpose LLM.

What's the benefit of running LLM's locally? #Privacy is a big one (it's running on your local machine, not a cloud server) - so you can ask it questions against sensitive business data, PHI/PII, etc.. You can also run it #offline (no Internet connection required) so if you wanted to #airgap your interactions, or play with it on vacation (on a plane, lost in the back country, etc.), you can absolutely do that - even with the Deepseek model.

I started playing with both LM Studio and ollama myself - been asking models basic questions like "what is the capital of Italy" and also more complex questions like "write me a #powershell script to add users of a specific OU to a number of Security Groups within AD" and so far, it's been very accurate. The PowerShell script llama3.1 provided worked out of the box (after I revised variables to match my environment).
