I'm doing Internet measurements & information services, with interest in #InfoSec @ RIPE NCC (RIPE Atlas&related). My opinions are mine or so I think!

If this does not trigger a #GDPR fine, then what does ...? "[...] far too much data was stored for far too long a period. [...] the data was not properly protected. Odido was also insufficiently transparent and did not properly adhere to the reporting obligations."

I left #odido 14 years (!) ago. I did not get notified about the breach by them. Yet I started getting spam "from Odido and their partners" about the week after the breach. Coincidence? Or 6.2 million is not really correct nltimes.nl/2026/04/20/cla…

Anthropic decidió dar de baja a toda nuestra organización por una supuesta infracción de sus condiciones de uso. Qué política específica infringimos no tengo ni la menor idea: simplemente recibimos un mail y listo, adiós Claude. Si querés apelar la medida hay que completar un Google Form, así de ridículo como suena. De golpe más de 60 personas se quedaron sin una herramienta fundamental para trabajar. Integraciones, skills, historial de conversaciones: todo perdido o, en el mejor de los casos, parado por tiempo indeterminado. Enorme aprendizaje para cualquier empresa de software que dependa de herramientas de IA en procesos críticos. Nunca hay que poner todos los huevos en una canasta.

@claudeai you took down our entire organization with 60+ accounts belonging to a legitimate company for no apparent reason, without any explanations. The only way to appeal the decision is by filling out a Google Form? Very bad UX and customer service.

There is massive irony in how AI coding tools are starting to become TOO expensive for many enterprises - after eg Anthropic removed subsidizing AI subscriptions. We might go from "everyone use AI for everything!" to "you have $300/month AI budget; use your brain for the rest."

"AI is single handedly the largest theft of plagiarism that has ever happened in human history."
Dave Kennedy@HackingDave

Alright, I've stayed away from the Mythos stuff for a little bit. Going to comment on that, but AI as a whole. First, this AI industry is absolutely insane. I feel like I'm back in the 90s/2000s with innovation, but it's not tempered or methodical - it's pure chaos. Everyday there is some AI-dude-bro (or gal) clawing for followers claiming end of cybersecurity, end of software engineering, or this breakthrough changes everything. We're seeing the "streamer" effect of video games now exploding in every industry that hasn't been in whatever industry, but is now a AI-expert thus an expert in anything AI touches because they can prompt. Largely it's not, but what it is doing is requiring us to understand what AI will do to virtually every industry in the future. I'm sitting here right now at a conference I'm presenting at, and I spoke with an individual which was like man... I'm just trying to get through this SAP implementation at my company, I don't even know where to start with AI at the moment. We are still in the extreme early stages of what AI can do, and I think that's really the exciting part - we are at the infancy stages of this. Most enterprise can't handle AI, as most companies couldn't handle agile workflow when it came out either, it took time, but eventually adopted. I won't dive deep into the scalability of releasing AI to the masses based on compute, power, or subsidies because these are real hurdles we need to solve. As you can see with Claude's spike in popularity is causing them to have to dumb the model down upwards of 65% just to stay afloat (Claude is absolutely awful right now for coding - beware). Mythos is cool, really cool - but it's not earth shattering as claimed. The potential here we are seeing a glimpse of what can actually happen though. The ability to do extremely complex tasks, with insane context windows, and high-end reasoning. But, what we saw from other current frontier models including open LLMs, they were able to find the same issues, but had to be specifically targeted towards those code sections because of context limitations and complex task reasoning which was drastically improved in Mythos. What does this mean? Basically. Nothing. It's a lot of marketing hype - but it does prove out that as these models become smarter, it will inevitably produce much better code, be able to work in mind blowing fashions that we haven't seen before - but it will all come down to cost. Right now Mythos is extremely expensive because of the compute needed, and we may solve that over time, but it's not there yet. The subsidies right now means AI is not ready. Scale is our biggest bottleneck right now and until that's solved, the industry will not move as fast as it could. What's particularly impressive is how the open models are starting to perform on par (or better) with the frontier models and become way more efficient without restrictions (turboquant) as an example. Our ability to use near parity models on our own hardware will only continue to get better which is a huge threat for these companies. I at first looked at Cursor's implementation of Kimi as they were falling behind because it wasn't "their own model". That wasn't accurate, its that the open models are performing substantially better than from 6 months ago, and will soon be leading the charge or close to it. What does this mean for cybersecurity? The industry is changing rapidly, and I absolutely freaking love it. We needed a swift kick in the ass in this industry that was largely stagnant for the past 10-15 years. What used to be a handful of incredibly talented security researchers that knew systems internals, savants at reverse engineering and reading through millions of lines of ASM is now being afforded to the masses, but still has a long way to go. The reason AI is so good at doing this stuff is because they paved the way, and will continue to do so in different ways. Not eliminated or removed, enhanced and better than ever. AI is single handedly the largest theft of plagiarism that has ever happened in human history. I just got a 10K check from Claude for ripping off my Metasploit book to train its model to be smarter actually :P I am all for things that make the world a safer place. Our goal in cybersecurity is to fix the world, make it less harmful when using technology - we should be adopting this. Note that it's going to come with a ton of fluff, hype, doomsday predictions, people that are now AI exports or coding experts but have never written a line of code themselves. That's all to be expected if you have ever been to an RSA conference. AI will product meaningful change in an industry that needed it. Cybersecurity is much more than bugs or defects, it's protecting against risk. AI is a new emerging risk, it's going to keep us insanely busy right now, and for the foreseeable future.

Microsoft suspend les comptes de 2 développeurs de logiciels libres de sécurité honorablement connus, WireGuard (VPN) et VeraCrypt (chiffrement de fichiers). C'est inquiétant, et pas tellement surprenant (= peut-être corrélé avec) le mouvement anti-sécurité chez les big techs.
vx-underground@vxunderground

Microsoft suspended the developer account for WireGuard (and also VeraCrypt). Why? Literally nobody knows. Presumably it's because Microsoft hates everyone and wants us all to suffer.

I think I got my first scam email that leads me to an #IPv6 website. It may also be why gmail is not considering it spam

For those who didn't know: side / vertical tabs already existed in #Chrome *more than a decade ago*. It was removed, despite user demand for it (not just from me, check this: issues.chromium.org/issues/40640156) b/c it "didn't pan out" and there was "no demand".
Robert Kisteleki@kistel

Many moons ago Chrome devs removed vertical tab support claiming "nobody needs this, too complex". That turned away users (including your truly). Yes there are alternative solutions, but at least *one* browser figured users actually need this. Well done! brave.com/vertical-tabs/

Assuming this is true, it's beyond surveillance capitalism
Hedgie@HedgieMarkets

🦔LinkedIn has been injecting a JavaScript fingerprinting script into every page load that scans visitors' browsers for 6,236 installed Chrome extensions and collects hardware data including CPU core count, available memory, screen resolution, time zone, battery status, and storage capabilities. The script targets extensions from competing sales intelligence products like Apollo, Lusha, and ZoomInfo, along with over 200 other competing tools. Because LinkedIn accounts are tied to real names, employers, and job titles, the extension and device data can be linked back to identify specific individuals. LinkedIn says the scanning is used to detect extensions that scrape data in violation of its terms of service. My Take LinkedIn's explanation that this is about detecting scraping tools is technically plausible for some of the 6,236 extensions being scanned. It is less convincing for the grammar tools, tax professional software, and other categories with no obvious connection to data scraping that are also in the list. Scanning for 200 competing sales intelligence products specifically looks less like platform protection and more like competitive intelligence gathering on your own users. What I'd want people to understand is what the hardware fingerprinting actually means in practice. CPU count, memory, screen resolution, battery status, and timezone combined with a real name and employer creates a device profile that follows you across the web even if you log out. LinkedIn is a platform most people use because they feel professionally obligated to. That captive audience dynamic makes the aggressive data collection harder to push back against than it would be on a platform you could simply stop using. Hedgie🤗

Ranking engineers by token volume is like judging chefs by the weight of their trash cans. It’s a metric that actively incentivizes the exact opposite of what you want: it rewards bloated, unoptimized code and penalizes the rare, elegant solution that solves a problem in three lines instead of three hundred. The danger is that it turns engineering into a "throughput" factory where the goal is to keep the machines humming, not to solve business problems.

I have stopped being their client 14 years ago (!!), yet only started getting scam SMSes for "their number" just after the breach. Coincidence? I think not. The statement that they don't keep customer data after 2 (or 10!) years is provably false. nltimes.nl/2026/03/26/oid…

The enormous Data Sciences/AI building my university is constructing kind of baffles me. We’re building for a world where huge numbers of humans congregate to conduct research on AI, but also apparently building for a world where AI has failed to make that approach obsolete.
