I drink whisky and I know things, mainly cyber. All views are my own.

@TheodorGanescu @IT_unhinged This was the best sarcastic response today. Thanks.

@PolestarCars lost my car 24hrs before delivery. They don't know where it is or when it might arrive. I know a few other delivery companies who operate like that, but they often lose smaller boxes and parcels, not 2.5 ton cars. #lost #polestar #CheckYourDoorstepsAndPorches

AI is disrupting bug bounties.
Security talent is being squeezed.
The rules are changing.

At #CyberThreat2025, Katie Moussouris explains what comes next — and how we prevent AI from eroding the expertise cybersecurity depends on.

Last week at SANS London, the #UKCyberTeam took on a high-impact training day led by @xzer0f.

Teams built real cloud services, then defended another team’s environment using only handover docs.

A true test of teamwork, clarity, and pressure.

After getting fired from ungrateful AWS after outage where my job was to vibecode all the DNS entries to IPv6, happy to announce it's my 1st day at Azure

Azure recognizes the value of vibecoding IPv6 DNS and I just force pushed my first 1m entries

Now off to grab some coffee

@YorkshireWater Sent you a DM, we're now on bottled water as tap water is undrinkable. Fyi, we won't be paying for the last few days, your chief execs bonus should cover the shortfall.

[Simon Vernon @xzer0f]

Hey @YorkshireWater the water in Nidderdale tastes metallic and bitter, has done for a few days now. @YorkshireTea says get it sorted, you're ruining people's lives!!

More good news! This weekend, the #UKCyberTeam gave back to the community by contributing 23 challenges to the @BSidesBRS CTF.

The response was fantastic, and we’re so proud of the team for sharing their skills.

Special thanks to @xzer0f for coordinating, QA’ing & deploying 👏

Damn it, I 3d printed mine from an online repo, does that still count?

if you don't hand make the CPU you use, are you really a cyber security professional????!!!!!!

@Ryanair For $19.99 I'd only expect to be fired out of a cannon towards my destination, I would expect @Ryanair to miss, be late and decapitate me in the process then blame the weather for the inconvenience.

[Simon Vernon @xzer0f]

I'm assuming you conveniently forgot that the UK already has a law requiring users to hand over credentials / keys. This additional 'request' is a sweeping power too far and Apple have justly refused. You have also just embarrassed the UK by 'demanding'. Poor form!

[Rt. Hon Ben Wallace @BenWallace70]

@LukeGaughan @tomhfh well for one the people who love encryption most are pedophiles. Even the US has a law ( dating way back) that forces platforms to proactively hand over some data.

@SkyBet says it “fundamentally disagrees” with the judgment and is considering an appeal. “Protecting our customers is the number one priority,” it said.

After it engaged in social engineering a habitual gambler to gamble more, with targeted emails, free spins, bonus deals.

[Simon Vernon @xzer0f]

@RadissonHotels #bloomsbury since you ignore emails and premium member calls to complain I'll do it here instead. Overbooking and moving reservations is not a good practice, especially to a sub standard hotel. Ignoring complaints is worse.

@northyorksc Cannot believe you have closed the A59 for that, again. It's only been open for 6 months since the last time. It's about time your councillors were vetted to make sure no one is cashing in on these repeated closures.

In the past few months, I've been making a subdomains database containing 1.6 billion subdomains scrapped from multiple public (and private) sources.
This database is now public and FREE and can be queried on the following website.

Enjoy!

Ps. I'm Microsoft partner.

[Simon Vernon @xzer0f]

@Microsoft you quietly created a feature that prevents using custom domains in your #microsoft365 personal and family accounts, which I've purchased as gifts for family members. They are now useless and we'll be using Gmail from this point forward.. #OwnGoal #MissedThePoint
