Here is a picture to describe the current situation in middle east.

I will be presenting "Our Vulnerable Networks" at #Sikkerhetsfestivalen 2026, talking BGP & RPKI history, status & "how to get it done".

Through history back to 1989 (BGP), L0pht testifying for congress in 1998 and lots more, I will explain the problem, the gaps, current status and what we need to do to fix a global internet routing security issue that is exploited many times daily.

Thanks to @internet_nl & @ripencc for their tools & knowledge, and the @cloudflare routing radar!

Listening to Trump live from #WEF #WorldEconomicForum in Switzerland, I asked ChatGPT to create an alternate short speech for DJT. The result? Very presidential, but still undoubtedly in the language typical of Donald.

"Thank you Elon Musk for making Grok so easy to use for both picture & video generation"

My first attempts at Grok confirms my fears - although I was happy with this result, created in seconds.

Hot off the #PasswordsCon press:

Scandinavian Airlines (SAS) has launched Passkeys support, and they have chosen to call it "Hovednøkkel" in Norwegian. Directly translated to english = "Mainkey".

1) you don't have to remember a password. With "mainkeys" you can use stuff like fingerprint or face to login.

2) Works on all your units. "Mainkeys" will automatically be available across all your synchronized devices.

3) Keep your account safer. "Mainkeys" offers "state of the art" phishing protection.

Made another AI song, this time for everyone who does vulnerability / change / patch / hardening / scanning management. And more.

I've done something I thought I would never do.

I've used Anthropic Claude to "vibe" code a Chrome plugin to test if a website is protected with DNSSEC & RPKI for BGP.

Warning: it seems to work. USE AT YOUR OWN RISK! Feedback wanted. 😬
