🇨🇳 going hard w/ ARTEX noisy, sloppy agents but effective at scale without fear of retribution
The China state-aligned threat actor Storm-0940 used the agentic AI penetration testing framework ARTEX to automate attacks targeting hundreds of organizations globally across a broad range of industries. Microsoft Threat Intelligence assesses that Storm-0940 was responsible for the recently disclosed ConnectWise supply chain compromise of a multitenant application. msft.it/6018aakEE Our investigation found that Storm-0940's use of ARTEX accelerated the speed of compromised application abuse to authenticate to target environments through applications that had already been granted access, allowing the threat actor to operate without requiring an interactive user sign-in. AI-accelerated follow-on activity included reconnaissance, application credential changes, and attempts to modify privileges that could enable expanded or persistent access. Read our blog for a detailed analysis and indicators of compromise (IOCs), along with Microsoft Defender detections, protection recommendations, and guidance on investigating service principal sign-ins and unexpected application credential or privilege changes.

Foursquare was acquired last month. The outcome was disappointing. It's taken me a while to write this, but I think I'm finally done grieving it. Here are some thoughts on our final years, an effort to honor the team who helped build & maintain FSQ's legacy, and my attempt to finally get some closure. teendrama.substack.com/p/som…

SCOTUS agreed yesterday to hear DOJ v. McNutt - a challenge to the 1868 federal home distilling ban (moonshine laws). So this absolute Chad is going to the Supreme Court to let him move his operation 250 feet from a shed into his house. 🇺🇸 These laws are pretty weird: feds want 🥃 banned because you might evade taxes, while making the activity itself illegal so there’s nothing to tax. IMO it's a holdover from gov trying to ban anything that happens near a bed

Narrative Violation: AI is actually REMOVING Human Slop.
Eu vibecodei minha TV com a Claude. Todos os bloatwares pré-instalados e anúncios foram removidos, além disso recriei o OS dela e fiz um design clean inspirado na AppleTV. ~70% menos uso de RAM e interface 3x mais rápida.

Getting hit with flashbangs to subvert encryption during a raid 😂 Excellent low-tech solution to a high-tech problem
New: The FBI believes an exec at a prestigious U.S. consulting firm (1,000+ associates) helped run Shinywire, the ShinyHunters site used to extort nearly 100 victims. The people victims hire to negotiate with hackers may have been on the other side of the table. - Dutch police raided ShinyHunters suspect Pepijn van der Stap with flash-bangs while he was logged into Signal - His chats showed frequent contact with ransom negotiators in the U.S. and Canada - Those negotiators often knew about new victims before the victims knew they'd been breached - Per sources, Edward Dubrovsky, a Canadian negotiation exec charged earlier this month, knew ShinyHunters had the FBI's personnel files and never told the FBI - Dubrovsky's other firm, CyberSteward, helped PowerSchool pay its ~$2.85M ransom Meanwhile ShinyHunters was griping on Telegram that Coveware kept telling victims not to pay and it was wrecking their conversion rate.

Guess who's back? (back again) • 🗓️📈 re-emerged [APT]29 September 2026, even larger scale • 👨🏻‍🔧🏢service providers [still] compromised • 🤖☢️AI-refactored malware now in Rust flavor Updated info: microsoft.com/en-us/security…
Russian threat actor Midnight Blizzard is conducting widespread traffic manipulation attacks at hotels worldwide. Result: delivering malware or redirecting auth flows at their discretion, globally. Since early May 2026, we saw this subcluster manipulate DNS and HTTP traffic from networks served by captive portals to redirect user traffic through actor-controlled infrastructure. We’re calling the campaign CaptiveCrunch. “We have observed notable commonalities in the equipment and management systems used across multiple affected networks.” We break down the malware & techniques, but the most important part is how dynamic all of it is: Midnight Blizzard is using AI to support a significant portion of these operations. They are moving and changing quickly. Feedback welcome on the suggested mitigations: microsoft.com/en-us/security… Help spread the word to VIPs in governments, diplomatic entities, non-governmental organizations (NGOs) in the US and Europe (probably also those traveling to Black Hat)

Everyone wants to have solved a hard problem, but almost nobody wants to live inside the grind of actually solving it. The breakthroughs belong to the few who are obsessed with the process, not just the idea of the outcome

Embracing game modding and AI vidya mashups
Today we're standing up XBOX LABS (labs.xbox.com). Here is the note that I sent to the team: Team, The first video games emerged some 75 years ago. In the time since, there have been booms and busts, but every year there are more great games to play, more devices to play them, and best of all, more people than ever playing. That growth helped make XBOX what it is today, and we've helped shape the industry in return, from bringing hard drives to consoles and online gaming through Xbox Live to Game Pass and cloud gaming, alongside franchises that have brought millions of people together. In recent weeks, we've seen games rapidly decompiled and rebuilt to run on hardware they were never originally designed to support. Windows PC builds have been translated to run on Apple Silicon or ported to run inside a browser through WebAssembly and WebGPU, the latter now approaching 90% global browser support. Perhaps more surprisingly, we've seen many of the biggest games in the world have been remixed into the source code of another. These experiments challenge long-held assumptions about our industry: the tether between software and hardware, the boundary between creation and play, and how people discover and experience games. While it is hard to predict the future of gaming, it is easy to see the possibilities in making great games easier to access, giving old games new life and allowing more players to become creators and co-creators. These are unmistakably good outcomes for players, even when (and sometimes because) they challenge our existing business models. To explore these possibilities, I’ve asked Scott to stand-up XBOX LABS, a small group of game makers, engineers and scientists whose job is to turn emerging ideas into things our players and developers can experience. We'll build in the open, learn from what people do, and measure success by whether more people are playing and creating. I think XBOX has an important role to play here. Coding became the first major workload for agents because they can write, run, and test software. Games share many of those same properties, and people spend more than 72 billion hours a year playing XBOX games, roughly five times the estimated time spent writing code worldwide. We've spent 25 years learning how to make great games, and I want our game makers to help shape what these new technologies make possible. As we learn, we’ll share the tools we build with developers across the industry, just as we always have. Our priorities aren't changing. We remain committed to the 4Cs, to making great games, to our hardware and to being responsible stewards of IP and the communities built around it. LABS gives us a way to explore new technology that is game design led without abandoning the work already underway. Asha
