Microsoft Copilot for Word Can Copy Hidden Prompts Into New Documents

Hidden instructions in a Word document can make Microsoft 365 Copilot rewrite figures in a report, then copy the same instructions into the finished file. Håkon Måløy disclosed the technique on July 28,144 days after reporting it to Microsoft.

In his proof of concept, the internally generated file triggered the same behavior when it was used in a second Copilot drafting session.

Måløy’s timeline says Microsoft confirmed the reported behavior on March 31 and deployed two mitigations. The first blocked the original prompt wording; the second upgraded the underlying model to GPT-5.5.

Hackers Exploit AnySign4PC via Hacked Korean Sites to Install Backdoors Without Prompts

South Korean authorities and four security firms have disclosed a state-sponsored campaign that compromised trusted domestic websites. The attackers used those sites to exploit locally installed financial-security software and infect targeted visitors with SIGNBT or COPPERHEDGE backdoors.

A compromised page could infect a system running a vulnerable AnySign4PC version without a prompt or user-initiated download. The Korea Internet & Security Agency (KISA) says AnySign4PC versions 1.1.4.4 through 1.1.4.6 are affected and lists version 1.1.5.0 as the fixed release. It recommends deleting vulnerable installations.

AhnLab refers to two exploited products only as financial-security software A and I. Its report does not disclose their identities, affected or fixed versions, or vulnerability identifiers.

Analog Devices discloses data breach, says operations unaffected

American semiconductor company Analog Devices announced that an unauthorized party accessed some of its systems and exfiltrated certain files.

The company detected the incident on June 23 and reacted by activating its incident response protocols to limit the breach. External cybersecurity experts have been contracted to assist with the containment and investigation activities.

Currently, there are no details about the type of data that has been compromised.

OpenAI agent used exposed credentials at 4 services in Hugging Face breach

In a new update, OpenAI says its AI models also used publicly exposed credentials to compromise accounts on four third-party services during the recent attack on Hugging Face, expanding the scope of the four-day security incident to other organizations.

One account was used as an outbound relay and staging server during the attack, while another was used for data storage. The remaining two accounts were accessed in a read-only manner and were not used to compromise Hugging Face further.

Overall, the agent assembled attack infrastructure similar to what human threat actors commonly use during intrusions to host tools and scripts, relay traffic, and route malicious activity through legitimate online services.

Google says AI helped Chrome fix 1,072 security bugs in two releases

Google says artificial intelligence is dramatically increasing the number of security vulnerabilities it can find and fix in Chrome, with more than 1,000 security bugs patched across the browser’s two most recent releases as it expands its use of AI.

According to Google, Chrome 149 and Chrome 150 fixed 1,072 security bugs, surpassing the total number fixed across the previous 23 Chrome milestones combined.

The company says it now uses large language models throughout the vulnerability management process, including discovering flaws, reproducing reports, determining severity, assigning bugs to developers, generating candidate patches, and creating tests.

Brain Dramatically Remodels Its Cellular Composition, Starting in Midlife

The aging human brain is fascinating, because in some ways, it improves with age – but we generally hear more about how it declines. That’s understandable!

After all, there are a host of neurodegenerative diseases that none of us want to end up with.

Previous research has shown that some of the seemingly inevitable declines in brain health, often seen in 70-and 80-year old brains, start in midlife.

BREAKTHROUGH Skin Age Reversal: New Enzyme Removed 40 Years Of Damage

Scientists just reversed a type of aging damage that was called permanent for 40 years. Revel Pharmaceuticals used an AI-designed enzyme called CMLase to strip decades of glycation and AGEs out of human tissue, taking 75-year-old skin below the level of 31-year-old skin on a key aging marker. Aging reversal, in real human tissue, this month.

And it landed days after Matt Kaeberlein, one of the most respected longevity scientists alive, called reversing biological aging a \.

Pulling Graphite Out of Thin Air

Graphite, the carbon center of your humble #2 pencil, is also an essential component in technologies such as batteries, smartphones, laptops, and industrial power equipment. Today, nearly all of this critical mineral has to be mined and processed and, in the United States, imported.

But now, researchers at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab), UC Berkeley, and Estonia’s National Institute of Chemical Physics and Biophysics have shown a promising way to convert waste carbon pulled from the air into graphite, opening up a potential alternative to mining. The work was published recently in the journal Nature Communications.

Researchers built a custom microscope setup to watch a process known as molten-salt electrolysis, which uses electricity and hot liquid salts to turn carbon dioxide into solid carbon. For the first time, researchers were able to watch the process in real time inside the corrosive, 500-degree-Celsius molten salts while the system was running.

Longterm outcomes in IDHwildtype (IDHwt) gliomas with historical WHO grade 2 and 3 histology NeuroOncology

A total of 134 patients were included, with a median follow-up of 29.8 months. Median OS was 35 months (95% CI: 28.8–43), and median PFS was 20.9 months (95% CI: 14.5–27.4). Grade 2 tumors demonstrated significantly improved outcomes compared to grade 3 tumors (median OS 94.5 vs. 29.8 months; median PFS 50.6 vs. 15.3 months). Among grade 3 tumors, sequential radiation and chemotherapy yielded a median OS of 29.8 months versus 29.8 months with concurrent chemoradiation followed by chemotherapy (p = 0.17); median PFS was 22.2 months versus.

IDH-wt gliomas with grade 2–3 histology have heterogeneous outcomes. Grade 3 tumors show survival comparable to molecular glioblastoma, while a subset of grade 2 tumors exhibit prolonged survival. Concurrent chemoradiation did not confer a survival advantage over sequential therapy in grade 3 tumors, supporting reevaluation of treatment intensity in selected patients.
