Into infosec (all of it), amateur radio, microcontrollers and other hardware. If it makes a radio wave it's cool. Aspire to eradicate duhkha.

🚨 Someone just open sourced a full satellite ground station. You can now pull live data straight from space to your hard drive. It's called Ground Station. It tracks satellites, controls antennas, and decodes radio signals from orbit. All from a web dashboard on your laptop. No internet needed. Just a $30 SDR dongle and an antenna. Here's what it does: → Tracks hundreds of satellites in real-time with orbital predictions → Auto-controls your antenna to follow satellites as they pass overhead → Streams live radio signals from space through your SDR → Decodes weather satellite images from METEOR-M2 → Decodes SSTV, FSK, GMSK, BPSK, and AX.25 packets → Records raw IQ data with full metadata for playback → AI-powered transcription of intercepted voice transmissions → Schedules automated recordings so you capture passes while you sleep Here's the wildest part: You can set it to automatically detect when the ISS or a weather satellite is about to pass over your location, point the antenna, record everything, decode the data, and save it. All hands-free. You wake up to fresh satellite images on your hard drive. This is the kind of setup universities and government labs spend tens of thousands building. A Raspberry Pi, an RTL-SDR, and this repo. That's your ground station. 2,474 commits. Actively maintained. Built with Claude Code and Codex. 100% Open Source.

@cyb3rops There is many a manufacturing (hell, any a power plant) with PLCs with IP addresses you can not change and only telnet access abound. They’re rock solid, been there forever and aren’t leaving anytime soon.

People who laugh and comment “who still uses telnet” have no idea how this industry actually works - or how power plants, warships, factories, baggage handling systems and other control and logistics systems are planned, built and expected to last for decades
The Hacker News@TheHackersNews

⚠️ WARNING - An unpatched critical telnetd bug (CVE-2026-32746) lets attackers gain full system access with no credentials. One connection to port 23 is enough to trigger memory corruption and execute code as root. No patch yet. Prior telnet flaw is already exploited in the wild. 🔗Read → thehackernews.com/2026/03/critic…

🚨 Someone just built a real-time global intelligence dashboard and open sourced it for free. It's called World Monitor. Think of it as a CNN war room meets Bloomberg Terminal for geopolitics but anyone can use it. No paid OSINT tools. No expensive subscriptions. No classified access needed. Here's what this thing tracks in real-time: → Active conflict zones with escalation scoring → 220+ military bases from 9 countries → Live military aircraft tracking (ADS-B) → Naval vessel monitoring including "dark ships" going off radar → Nuclear facilities worldwide → Undersea cables, oil pipelines, and AI datacenter clusters → Protests, sanctions, internet outages, and satellite fire detection → Prediction markets as early warning signals Here's the wildest part: It has an AI that reads 100+ news sources, classifies threats in real-time, and generates intelligence briefs automatically. Every country gets a live "Instability Index" score from 0-100 based on military activity, protests, news velocity, and structural risk. When 3+ signal types spike in the same area, military flights + protests + satellite fires, it triggers a convergence alert. This is the kind of tool governments pay millions for. It runs in your browser. One command to install. 100% Open Source. MIT License.

If your GameCube is missing the SP2 port, this $5 adapter from @collingall is a good alternative. Its not as good as the SD2SP2...but if you don't have the SP2 port, you don't really have a choice, do you? ;p retrorgb.com/sd2sp1-for-gam…

Thought this was a nothing burger until they mentioned follow on impact “allows an attacker to gather credentials, such as local user and SIP accounts, stored on a compromised GXP1600 device”.
Rapid7@rapid7

🚨 In conducting 0 day research against #Grandstream GXP1600 VoIP phones, Rapid7 Labs discovered CVE-2026-2329. The unauthenticated stack-based buffer overflow vuln ultimately allows an attacker to intercept phone calls and eavesdrop on audio. Read on: r-7.co/4tIzope

I am excited to release the extended version of the sixth article in the Exploiting Reversing Series (ERS). Titled "A Deep Dive Into Exploiting a Minifilter Driver (N-day)" this 293-page deep dive offers a comprehensive roadmap for vulnerability exploitation: exploitreversing.com/2026/02/11/exp… Key updates in this extended edition: [+] Dual Exploit Strategies: Two distinct exploit versions. [+] Exploit ALPC Write Primitive Edition: elevation of privilege of a regular user to SYSTEM. [+] Exploit Parent Process ID Spoofing Edition: elevation of privilege of an administrator to SYSTEM. [+] Solid Reliability: A completely stable and working ALPC write primitive. [+] Optimized Exploit Logic: Significant refinements to the codebase and technical execution for better stability and predictability. For those who have read the original release, whose exploit was working, my strong recommendation is that you adopt this extended edition as definitive. The article guides you through the entire lifecycle of an exploit: from initial reverse engineering and vulnerability analysis to multiple PoC developments and full exploitation. I hope this serves as a definitive resource for your research. If you find it helpful, please feel free to share it or reach out with your feedback! Enjoy your reading and have an excellent day day.

Hey guys! Here’s my latest research. I've dubbed it: Living off the Process😺. I wanted to leverage already existing artifacts in a remote process to execute shellcode. We will hunt for ROP gadgets, assembly stubs, preexisting RWX memory, etc! g3tsyst3m.com/lotp/Living-of…

🧵I’m building a hardware startup in 2026. 🛠️ You don't need a million-dollar lab to ship a product, but you do need the right essentials. Here is a breakdown of the electronics equipment on my bench, what it costs, and a rating of how essential it actually is.👇

@natalie_thenerd What have you been using for GB and GBA IPS shells? I’ve been buying he HISPEEDIO screen and shell bundles but I’d like to start getting some that aren’t flat colors. A couple Pokémon shells would be rad.
