AI & Humans: Making the Relationship Work
Leaders of many organizations are urging their teams to adopt agentic AI to improve efficiency, but are finding it hard to achieve any benefit. Managers attempting to add AI agents to existing human teams may find that bots fail to faithfully follow their instructions, return pointless or obvious results or burn precious time and resources spinning on tasks that older, simpler systems could have accomplished just as well.

A Cyberattack Was Part of the US Assault on Venezuela
We don't have many details: President Donald Trump suggested Saturday that the U.S. used cyberattacks or other technical capabilities to cut power off in Caracas during strikes on the Venezuelan capital that led to the capture of Venezuelan President Nicolás Maduro. If true, it would mark one of the most public uses of U.S. cyber power against another nation in recent memory. These operations are typically highly classified, and the U.S. is considered one of the most advanced nations in cyberspace operations globally.

Telegram Hosting World’s Largest Darknet Market
Wired is reporting on Chinese darknet markets on Telegram. The ecosystem of marketplaces for Chinese-speaking crypto scammers hosted on the messaging service Telegram have now grown to be bigger than ever before, according to a new analysis from the crypto tracing firm Elliptic. Despite a brief drop after Telegram banned two of the biggest such markets in early 2025, the two current top markets, known as Tudou Guarantee and Xinbi Guarantee, are together enabling close to $2 billion a month in money-laundering transactions, sales of scam tools like stolen data, fake investment websites, and AI deepfake tools, as well as other black market services as varied as…

404 Media has the story: Unlike many of Flock's cameras, which are designed to capture license plates as people drive by, Flock's Condor cameras are pan-tilt-zoom (PTZ) cameras designed to record and track people, not vehicles. Condor cameras can be set to automatically zoom in on people's faces as they walk through a parking lot, down a public street, or play on a playground, or they can be controlled manually, according to marketing material on Flock's website.

LinkedIn Job Scams
Interesting article on the variety of LinkedIn job scams around the world: In India, tech jobs are used as bait because the industry employs millions of people and offers high-paying roles. In Kenya, the recruitment industry is largely unorganized, so scamsters leverage fake personal referrals. In Mexico, bad actors capitalize on the informal nature of the job economy by advertising fake formal roles that carry a promise of security.

Are We Ready to Be Governed by Artificial Intelligence?
Artificial Intelligence (AI) overlords are a common trope in science-fiction dystopias, but the reality looks much more prosaic. The technologies of artificial intelligence are already pervading many aspects of democratic government, affecting our lives in ways both large and small. This has occurred largely without our notice or consent. The result is a government incrementally transformed by AI rather than the singular technological overlord of the big screen.

Friday Squid Blogging: Squid Camouflage
New research: Abstract: Coleoid cephalopods have the most elaborate camouflage system in the animal kingdom. This enables them to hide from or deceive both predators and prey. Most studies have focused on benthic species of octopus and cuttlefish, while studies on squid focused mainly on the chromatophore system for communication. Camouflage adaptations to the substrate while moving has been recently described in the semi-pelagic oval squid (Sepioteuthis lessoniana).

This is pretty scary: Urban VPN Proxy targets conversations across ten AI platforms: ChatGPT, Claude, Gemini, Microsoft Copilot, Perplexity, DeepSeek, Grok (xAI), Meta AI. For each platform, the extension includes a dedicated "executor" script designed to intercept and capture conversations. The harvesting is enabled by default through hardcoded flags in the extension's configuration. There is no user-facing toggle to disable this.

Denmark Accuses Russia of Conducting Two Cyberattacks
News: The Danish Defence Intelligence Service (DDIS) announced on Thursday that Moscow was behind a cyber-attack on a Danish water utility in 2024 and a series of distributed denial-of-service (DDoS) attacks on Danish websites in the lead-up to the municipal and regional council elections in November. The first, it said, was carried out by the pro-Russian group known as Z-Pentest and the second by NoName057(16), which has links to the Russian state. Slashdot thread.

Microsoft Is Finally Killing RC4
After twenty-six years, Microsoft is finally upgrading the last remaining instance of the encryption algorithm RC4 in Windows. of the most visible holdouts in supporting RC4 has been Microsoft. Eventually, Microsoft upgraded Active Directory to support the much more secure AES encryption standard. But by default, Windows servers have continued to respond to RC4-based authentication requests and return an RC4-based response.

At least some of this is coming to light: Doublespeed, a startup backed by Andreessen Horowitz (a16z) that uses a phone farm to manage at least hundreds of AI-generated social media accounts and promote products has been hacked. The hack reveals what products the AI-generated accounts are promoting, often without the required disclosure that these are advertisements, and allowed the hacker to take control of more than 1,000 smartphones that power the company.

Chinese Surveillance and AI
New report: "The Party's AI: How China's New AI Systems are Reshaping Human Rights." From a summary article: China is already the world's largest exporter of AI powered surveillance technology; new surveillance technologies and platforms developed in China are also not likely to simply stay there. By exposing the full scope of China's AI driven control apparatus, this report presents clear, evidence based insights for policymakers, civil society, the media and technology companies seeking to counter the rise of AI enabled repression and human rights violations, and China's growing efforts to project that repression beyond its borders.

I have no context for this video -- it's from Reddit -- but one of the commenters adds some context: Hey everyone, squid biologist here! Wanted to add some stuff you might find interesting. With so many people carrying around cameras, we're getting more videos of giant squid at the surface than in previous decades. We're also starting to notice a pattern, that around this time of year (peaking in January) we see a bunch of giant squid around Japan.

Against the Federal Moratorium on State-Level Regulation of AI
Cast your mind back to May of this year: Congress was in the throes of debate over the massive budget bill. Amidst the many seismic provisions, Senator Ted Cruz dropped a ticking time bomb of tech policy: a ten-year moratorium on the ability of states to regulate artificial intelligence. To many, this was catastrophic. The few massive AI companies seem to be swallowing our economy whole: their energy demands are overriding household needs, their data demands are overriding creators' copyright, and their products are triggering mass unemployment as well as new types of clinical…

The promise of personal AI assistants rests on a dangerous assumption: that we can trust systems we haven’t made trustworthy. We can’t. And today’s versions are failing us in predictable ways: pushing us to do things against our own best interests, gaslighting us with doubt about things we are or that we know, and being unable to distinguish between who we are and who we have been.
