If you've ever wondered why smart TVs are so cheap, this is why. @log4j rooted his Samsung and found an always-on hot mic, automatic content recognition, geolocation, network mapping, ad targeting and user profiling, shared with Samsung's "400 partners". A lot of it can be blocked in <15 min, wrote a basic guide below. What your TV is doing The main culprit is ACR (automatic content recognition). Your TV screenshots what's on screen, fingerprints it, and sends it home to build your ad profile. Samsung does it every 500ms, LG every 10ms [1]. What is insane: it happens on connected devices too. Plug in your laptop, your console, your work machine, and your TV can fingerprint that via HDMI [1]. He also found that if your Samsung doesn't have a mic, it'll look for one from a connected soundbar or bluetooth device. xitter.cf/log4j/status/211376224… It's on by default, and you likely agreed to it on the setup screen you clicked through in 10 seconds. Step 1: Turn off ACR Samsung: Terms & Privacy → Viewing Information Services LG: Live Plus Vizio: Viewing Data Roku: "Use info from TV inputs" Sony/Google TV: Samba Interactive TV Menus vary by model, but those are the names to look for. While you're in there, opt out of interest-based ads, reset your advertising ID, decline every optional privacy agreement, turn off voice recognition, and delete apps you never open. Step 2: Give smart devices their own network Put the TV, cameras, speakers and vacuum on your router's guest/IoT network. The logic is simple: these devices rarely get patched. If one gets compromised (getting drastically more frequent with AI), it shouldn't be able to see your other devices or home network. Step 3: Block trackers for the whole house with DNS-level filtering NextDNS (cloud-based) is easy and has a solid free plan. Pi-hole is a little bit more work if you prefer self hosting. For simplicity we'll focus on the former. 1. Sign up at nextdns.io (free tier is plenty) 2. Privacy tab: add a blocklist (OISD is a good bet) and turn on Native Tracking Protection for Samsung, LG, Roku, Amazon (see attached image) 3. Setup tab: copy your endpoint 4. Paste it into your router's DNS settings as DNS-over-HTTPS/TLS (or use the IPs + "Link IP" if your router only does plain DNS) 5. Bonus: block outbound port 53 except to your router. Some devices hardcode their own DNS to get around you Then open the NextDNS logs and watch how often your TV phones home. It's eye-opening. If an app or update breaks, find the domain in the logs and allowlist it. Why they do this TV prices are down 97% since 2000 [2]. Most of that is better manufacturing and brutal competition. But once margins on the hardware hit zero, the cost moved to you. In Q3 2024, Vizio lost $6.7M selling TVs and made $115.8M in gross profit from ads and viewing data [3]. They've said on earnings calls that they keep TV prices low to grow the audience they sell to advertisers. Walmart bought them in 2024. This isn't a conspiracy theory either. Vizio paid $2.2M to the FTC in 2017 for tracking 11 million TVs without consent. Last December, Texas sued Samsung, LG, Sony, Hisense and TCL over ACR. Samsung and LG have since agreed to stop collecting that data without explicit consent [4]. TL;DR 1. ACR off 2. Ads + voice off 3. Smart devices on their own network 4. NextDNS filtering on the router Sources: [1] ACR study: arxiv.org/abs/2409.06203 [2] Cost of US consumer goods: aei.org/economics/chart-of-t… [3] Vizio Q3 2024: sec.gov/Archives/edgar/data/… [4] Texas v.

The potential impact of the ConnectWise supply chain attack is massive. One compromised OAuth application with elevated permissions could give attackers access to emails, files, and directory data across hundreds of Microsoft 365 tenants. Even worse, attackers could establish persistent access by adding credentials to other applications, surviving the revocation of the original compromised credentials. And with MSPs involved, the potential blast radius could extend even further to downstream customers. We don't know the full extent of the compromise yet, but this could affect far more organizations than those directly using ConnectWise Cloud Backup. linkedin.com/posts/microsoft…

Anthropic published real AI intrusion data that probably deserves more attention than speculative concerns over the probability of AI doom. Both concerns can coexist, but one has practical risk that directly impacts most enterprises in the short-term -- whereas the other should probably dictate how the AI labs [are forced to] behave
Replying to @ItsReallyNick
Anthropic has now published their side of this APT29 🇷🇺 cyber espionage campaign, complete with a timeline of capability development & intrusions: anthropic.com/threat-intelli… ...helpful data to support prior comments about Midnight Blizzard's CaptiveCrunch being enabled by AI

We are just a few days away from Black Hat and our @DecibelVC GameDay event for founders and early adopters. As AI starts finding bugs faster than humans can patch them, is there anything hotter than the battlegrounds where AI meets cyber? The zero day clock is ticking faster than ever. With AI agents now discovering, weaponizing, and exploiting vulnerabilities in hours instead of months, the window between disclosure and attack is collapsing. Will the race to find bugs first become the new arms race in cyber? Come join our GameDay "Zero Day Countdown" on this hot topic with our friends: @caseyjohnellis, Founder of disclose.io Zakir Durumeric, Founder of @censysio @jcran, Founder of Mallory Please register for your GameDay pass which will give you entry to all events on Tuesday - links in comments below and we look forward to seeing you there!

underrated part of the story is huggingface couldn't use oai or ant models to investigate the incident due to guardrails, and were forced to use chinese open-source models to attempt to defend themselves against what turned out to be the frontier model hacking them. Wild times.

Introducing a new side project called Model Regression. It tests daily Claude, GPT, and Grok on various benchmark statistics to determine how well its performing and to identify model degrades over time. @edskoudis had an idea for model testing before they conducted offensive testing to ensure the model was performing as expected, and @BlasikRandy pushed me down this road with actually going and doing it. The main intent here is the frontier models will experience outages, issues, bugs, intentional/unintentional nerfing of the models without notice. You can't typically trust day to day activities in these models for stability, so leveraging this on your daily routine to see how well the model is performing for that day is something I'll be using everyday. Runs every morning in my DGX sparks environment and automatically updates with how well its performing. Enjoy! modelregression.com/ Also open-sourced the project, can run on your own server as well and look at the benchmarks and how they are calculated: github.com/HackingDave/model…

My biggest takeaways from Claude Code's Head of Product @_catwu: 1. Anthropic’s product development timelines have gone from six months to one month, sometimes one week, sometimes one day. Part of this acceleration is access to the latest models (i.e. Mythos). Another is shipping new products into “research preview,” making clear it's early, experimental, and might not be supported forever. Another is an evergreen "launch room "where engineers post ready features and marketing turns around announcements the next day. 2. The PM role is shifting from coordinating multi-month roadmaps to enabling teams to ship daily. As Cat puts it, “There should be less emphasis on making sure you are aligning your multi-quarter roadmaps with your partner teams and more emphasis on, OK, how can we figure out the fastest way to get something out the door?” 3. The most efficient shipping unit is an engineer with great product taste. On Cat’s team, many engineers go end-to-end—from seeing user feedback on Twitter to shipping a product by the end of the week—without a PM involved. Also, almost all the PMs on the Claude Code team have either been engineers or ship code themselves, and the designers have been front-end engineers. The roles are merging, and the most valuable skill is product taste, not job title. 4. Build products that are on the edge of working. Claude Code’s code review product failed multiple times because earlier models weren’t accurate enough. But because the prototype was already built, they could swap in Opus 4.5 and 4.6 and immediately test whether the gap was closed. Teams that wait for the model to be ready will always be a cycle behind. 5. The most underrated skill for building AI products is asking the model to introspect on its own mistakes. Cat regularly asks the model why it made an unexpected decision. The model will explain that something in the system prompt was confusing, or that it delegated verification to a subagent that didn’t check its work. This reveals what misled the model so the team can fix the harness. 6. Every model release forces their team to revisit existing products and audit their system prompt to remove features the model no longer needs. Claude Code’s to-do list was a crutch for earlier models that couldn’t track their own work. With Opus 4, the model handles it natively. Features built as scaffolding for weaker models become debt when the model catches up—so the team actively strips them. 7. Anthropic employees build custom internal tools instead of buying SaaS products. A sales team member built a web app that pulls from Salesforce, Gong, and call notes to auto-customize pitch decks—work that used to take 20 to 30 minutes now takes seconds. Their core stack is Claude Code, Cowork, and Slack. No Notion, no Linear, no Figma. 8. People underestimate how much Claude’s personality contributes to its success. As Cat describes it, “When you reflect on everyone you’ve worked with, there’s just some people where you’re like, I really like their energy, their vibe.” Claude is designed to be low-ego, positive, competent, and earnest—qualities that make it feel like a great coworker, not just a tool. This isn’t cosmetic; it’s what makes people want to use Claude for hours every day. The team has a dedicated person, Amanda, who “molds Claude’s character,” and it’s one of the hardest roles at the company because success is so subjective. 9. The future of work is managing fleets of AI agents, not doing the work yourself. Cat sees a clear progression: first, individual tasks become successful. Then people start running multiple tasks at the same time (multi-Clauding). Next, people will run 50 or 100 tasks simultaneously, which will require new infrastructure—remote execution, better interfaces for managing tasks, agents that fully verify their work, and self-improving systems that incorporate feedback. The human role shifts from doing the work to knowing which tasks to look into, verifying outputs, and giving feedback that makes the system better over time. 10. Hire people who lean into chaos and face every challenge with a smile. At Anthropic, there are weeks when a P0 on Sunday becomes a P00 by Monday and a P000 by Monday afternoon. If you get too stressed about any one thing, you’ll burn out. Their team looks for people who can look at a hard challenge and say, “Wow, that’s gonna be hard. But I’m excited to tackle it and I’m gonna do the best that I possibly can.” This mindset—optimism, resilience, and comfort with constant change—is increasingly essential as the pace of AI development accelerates.

How Anthropic’s product team moves faster than anyone else I sat down with @_catwu, Head of Product for Claude Code at @AnthropicAI, to get a peek into their unprecedented shipping pace, how AI is changing the PM role, and how to be the right amount of AGI-pilled. We discuss: 🔸 How Anthropic’s shipping cadence went from months to weeks to days 🔸 The emerging skills PMs need to develop right now 🔸 Why you should build products that don't work yet—then wait for the model to catch up 🔸 Why a 95% automation isn't really an automation 🔸 Cat’s most underrated AI skill (introspection) 🔸 What Cat actually looks for when hiring PMs now (hint: it's not traditional PM skills) Listen now 👇 youtu.be/PplmzlgE0kg

Had an awesome conversation with my friend @jcran and partner Mallory AI about their new offering. What he's been building there has been extraordinary, and I'm super excited for him to finally be sharing it with the world. Basically (my take), Threat Intelligence that is available to your agents! (They still have great interfaces for humans, too) :) So now my PAI system can interact with their API, which means I can ask about threat actors, TTPs, and all sorts of threat intel related content right from my digital assistant / agent harness. Insane stuff. Go check it out here: mallory.ai/blog/demoing-mall…
