Security on Baldarn's

PHP and certificates: a couple of hectic days for cybersecurity

Thu, 22 Oct 2026 00:00:00 +0000

A couple of hectic days: first PHP, then certificates.

What I did

I got the emails from the services I use, updated my servers and moved on.

The PHP issue required an update. The certificate one is sneakier: it affects HTTPS, which is what guarantees we’re really on the site we think we’re on, and not on a fake one.

No panic

Two serious security issues, sure. But they don’t strike me as a sign that something weird is happening because of AI.

Cloned voice scams: a family password to protect yourself

I got a message from a friend: he was at the dentist, couldn’t talk and needed 200 euros.

The attempt

I asked to talk on the phone. It was a scam, and it ended there.

But what if next time the voice really were his? With voice cloning, it takes very little material to reproduce someone’s voice. And fake videos are getting more and more convincing. Imagine a call with a family member’s voice asking you for help.

Cybersecurity: plants grinding to a halt and damage in the physical world

Standing in front of a Medici tower, which knows a thing or two about defense, I started thinking about cyber warfare. As an enthusiast, not an expert.

Compromised plants

I start from a story I heard: compromised refrigeration plants. Not stolen data, but machines shutting down and real damage in the physical world.

The problem is that security is often fragile. Default passwords, open access, the classic key under the doormat. And when we’re talking about infrastructure, the risk gets serious.
