Field notes from Hostin.tech
Tech, explained plainly.
Cybersecurity, OSINT, infrastructure and AI, explained through practical questions. Pick a topic, follow the sources and take away what is useful to you.
Useful AI without a ridiculous bill. What is the catch?
OpenCode, OpenRouter, existing hardware and a few well-chosen services. Cheap prototypes are possible. Confidentiality is a separate decision.
10 / Built in the workshopVibecoding: great for starting. Then what?
Describe it, generate it, try it, change it. The loop is powerful. The responsibility does not disappear.
09 / Change the viewpointWhat do I look like to someone looking for a way in?
Not a Hollywood hacker profile. A look at the picture your public information builds.
08 / Outside viewWhere could my domain get hit?
A vulnerable service, a stolen account, a convincing phone call, a supplier’s access. Here is how the first foothold actually happens.
07 / Security that runsAn ISO audit is coming. Start before the paperwork.
Here we mean ISO/IEC 27001, the information security standard. Not a generic “ISO badge”.
06 / Under the bonnetDue diligence: look under the bonnet before you sign.
Buying a company, backing a product, choosing a supplier: the demo is not the whole story.
05 / Inside the workshoph0sint.com: what does your infrastructure give away?
A project from the Hostin.tech workshop, built around a simple question: what can someone see from outside?
04 / Cyber, without the theatreCybersecurity, OSINT… what are we actually talking about?
Keeping things working. Then learning to notice what everyone can already see.
03 / Why Is This Public?Why does a public .git folder matter?
Repository metadata can reveal history that the current website no longer shows—but a scanner flag is still only an indicator.
02 / 20 Years of TechA backup is not a recovery plan.
A green dashboard proves that a job ran. It does not prove that the system, team or business can recover.
01 / Cyber From The RoadHotel Wi-Fi is not automatically evil.
It is simply not your network. Here is the useful threat model and the controls that still matter.
