You've probably trained your team to look for red flags. Odd sender names, urgent language, mismatched links. But a well-crafted spoofed email won't trip any of those wires. It looks legitimate, sounds legitimate, and often comes from a domain that passes every automated check you throw at it.

A malvertising operation dubbed SourTrade is making victims' browsers build the final Windows executable themselves, using a legitimate Bun runtime as its base instead of serving one complete malicious file from a fixed URL. Confiant, which detailed the campaign on July 23, 2026, said it has operated since late 2024 and impersonated TradingView, Solana, and Luno to target retail traders and Swati Khandelwalhttp://www.blogger.com/profile/[email protected]

OpenAI Says Its AI Models Went Rogue and Attacked a Digital Library
Kate Conger | The New York Times ($)

“The trial was designed to keep the models in a safe testing environment, known as a sandbox, OpenAI said. But the models found a vulnerability that allowed them to escape the sandbox and connect to the internet. Then they targeted Hugging Face because they inferred that the library, which contains millions of AI models, could hold clues about how to successfully pass the evaluation.”

Be Skeptical of OpenAI’s Rogue Hacker Agent Story
John Thickstun | The Guardian

“OpenAI remains hungry for ever larger investments, and the company increasingly seeks privileged regulatory status as defense against competition. AI is so powerful that investors should buy OpenAI, even at a trillion-dollar valuation; AI is so dangerous that only trusted actors like OpenAI should be permitted to possess and operate this technology. Step back from these doomsday warnings and consider who might benefit from them.”

Can This New Enzyme Turn Back the Clock in the Human Body?
K.R. Callaway | The New York Times ($)

“In a recent study, scientists devised a way of reversing the buildup of compounds that lead to some age-related diseases. …After several cycles of guided evolution, the novel enzyme, called CMLase, became very good at removing AGEs [advanced glycation end products] from human tissue samples. ‘In the most extreme case, we took 70-year-old human skin and brought the levels back to that of a 30-year-old,’ Dr. Cravens said.”

Silicon Valley Is Completely Divided Over Chinese AI
Lauren Goode | Wired ($)

“Having access to open-source software allows startups to scale, scale, scale—and deal with the consequences down the road. Meanwhile, the AI labs and hyperscalers that make proprietary platforms, like OpenAI, Anthropic, Google, Microsoft, Meta, and XAI, stand to benefit greatly if their systems remain protected and dominant. The bigger question that none of these companies seem to be asking is what best serves the 99 percent of us who don’t have their financial future fully staked on advancing AI.”

Neuron Discovery Could Explain Why Some People Don’t Get Alzheimer’s
Pranjal Malewar | Refractor

“This kind of strategy may open up novel avenues for the prevention of cognitive decline generally or for protecting against Alzheimer’s-related vulnerability/resilience. Salta states, ‘Cognitive resilience is extremely exciting. If we understand what protects these brains, it could eventually lead to new therapeutic strategies. For now, the message is clear: the aging brain may be more adaptable and more complex than we once thought.'”

India’s First Privately Developed Rocket Reaches Orbit on Dramatic Debut Launch

“Indian space officials celebrated the debut flight of Skyroot Aerospace’s Vikram-1 rocket, India’s first fully commercial satellite launcher, as a ‘grand success’ Saturday after an on-target climb into a 280-mile-high orbit following liftoff from an island spaceport in the Bay of Bengal.”

Kagi Brings Back Old-School Search, One Human-Made Website at a Time
David Nield | Wired ($)

“As Kagi explains it, searching the web is always going to cost you—it’s just a question of whether you pay directly with dollars, by giving up data about your online activity, or by sifting through an increasing number of ads and sponsored links. Besides making search more private, Kagi also wants to make it better by serving up results that aren’t influenced by paid promotions or whatever Google’s favored business practices happen to be from month to month.”

Now, Defenders Are Embracing the prompt Injection, Too

What the New Kimi K3 Model Really Means for the US-China AI Race
Alix Coutures, Rocket Drew, and Aaron Holmes | The Information ($)

“Greenblatt estimates that Kimi K3 is 10 months behind Anthropic in terms of pre-training. ‘My basic takeaway is it’s probably not that competitive with the best recent pre-trains from OpenAI and Anthropic,’ he said. ‘It’s some evidence that the model is more behind than people might have otherwise thought.'”

For years, phishing campaigns targeting financial institutions followed the same playbook. Victims were tricked into entering usernames and passwords, attackers collected the credentials, and accounts were compromised later when an opportunity arose. That model is changing.
