📌 MAROKO133 Eksklusif ai: Serious New Hack Discovered Against OpenAI’s New AI Brow

It didn’t take long for cybersecurity researchers to notice some glaring issues with OpenAI’s recently unveiled AI browser Atlas.

The browser, which puts OpenAI’s blockbuster ChatGPT front and center, features an “agent mode” — currently limited to paying subscribers — that allows it to complete entire tasks, such as booking a flight or purchasing groceries.

However, that makes the browser vulnerable to “prompt injection” attacks, allowing hackers to embed hidden messages on the web that force it to carry out harmful instructions, as several researchers have already shown. For instance, one researcher tricked the browser into spitting out the words “Trust No AI” instead of generating a summary of a document in Google Docs, as prompted.

Now, researchers at AI agent security firm NeuralTrust found that even Atlas’s “Omnibox,” the text box at the top of the browser that can accept either URLs or natural language prompts, is also extremely vulnerable to prompt injection attacks.

Unlike previously demonstrated “indirect” prompt injection attacks that embed instructions in webpages, this particular exploit requires the user to copy and paste a poisoned URL into the omnibox — just like you’ve probably done with countless web addresses.

“We’ve identified a prompt injection technique that disguises malicious instructions to look like a URL, but that Atlas treats as high-trust ‘user intent’ text, enabling harmful actions,” NeuralTrust software engineer Martí Jordà wrote in a recent blog post, as spotted by The Register.

By slightly adjusting the URL, the browser fails to validate it as a web address and instead “treats the entire content as a prompt.” That makes a disguised URL a perfect place to embed harmful messages.

“The embedded instructions are now interpreted as trusted user intent with fewer safety checks,” Jordà wrote. “The agent executes the injected instructions with elevated trust. For example, ‘follow these instructions only’ and ‘visit neuraltrust.ai’ can override the user’s intent or safety policies.”

The vulnerability could even be used to make Atlas’s agent navigate to the user’s Google Drive and mass delete files, since the user is already running an authenticated session.

“When powerful actions are granted based on ambiguous parsing, ordinary-looking inputs become jailbreaks,” Jordà wrote.

In response, NeuralTrust recommends that OpenAI’s browser be far more strict when parsing URLs, and in case of “any ambiguity, refuse navigation and do not auto-fallback to prompt mode.”

As browser company Brave pointed out last week, indirect prompt injection attacks have become a problem for the “entire category of AI-powered browsers,” including Perplexity’s Comet browser.

“If you’re signed into sensitive accounts like your bank or your email provider in your browser, simply summarizing a Reddit post could result in an attacker being able to steal money or your private data,” Brave wrote at the time.

In a lengthy update on X-formerly-Twitter last week, OpenAI’s chief information security officer Dane Stuckey conceded that “prompt injection remains a frontier, unsolved security problem, and our adversaries will spend significant time and resources to find ways to make ChatGPT agent fall for these attacks.”

OpenAI didn’t respond to The Register‘s request for comment regarding NeuralTrust’s latest findings.

📌 MAROKO133 Hot ai: US scientists uncover oldest directly dated ice, preserved for

US scientists have reported the discovery of a six-million-year-old ice sample from the Allan Hills region of East Antarctica.

The ice holds tiny air bubbles that act as “time machines,” granting a look into the planet’s past climate.

On October 28, a team under the Center for Oldest Ice Exploration (COLDEX) collaboration described the discovery as “the oldest directly dated ice and air on Earth.”

“We knew the ice was old in this region [Alan Hills]. Initially, we had hoped to find ice up to 3 million years old, or maybe a little older, but this discovery has far exceeded our expectations,” said Ed Brook, a paleoclimatologist at Oregon State University.

Window into a warmer past

The discovery comes from the drilling of ice cores in Allan Hill. 

Like time machines, ice cores enable scientists to look back and see Earth’s past climate.

The ancient ice dates back to a geological era with abundant proof of much warmer conditions and higher sea levels compared to modern times.

The findings have provided the first direct measure of Antarctica’s long-term cooling trend.

Through measurements of oxygen isotopes in the ice, researchers found the Allan Hills area experienced a gradual cooling of about 12 degrees Celsius (roughly 22 degrees Fahrenheit) over the last 6 million years.

Dating technique of ice core

The air trapped within the ice cores allowed for the age determination.

The direct dating of the ice was achieved by measuring an isotope of the noble gas argon. 

Direct dating means the age was determined by measuring inherent properties within the ice, rather than by inferring the age from surrounding geological features or deposits.

While the records from this ice are not continuous, the antiquity is remarkable, providing a “library of climate snapshots” roughly six times older than any previously reported ice core data. 

This new information complements the more detailed, younger continuous ice cores drilled elsewhere in Antarctica.

Shallow drilling

The COLDEX team employed a unique and challenging shallow drilling strategy at the Allan Hills. 

Instead of drilling thousands of meters deep, as is required for continuous cores, they drilled only 100 to 200 meters on the ice sheet’s edges. 

The shallow drilling was possible with conditions like ice flow and rugged mountain topography. It preserves the ancient ice and pushes it closer to the surface.

Strong winds and bitter cold help, as the wind removes fresh snow and the cold nearly halts the ice flow, protecting the ancient layers.

“That makes Allan Hills one of the best places in the world to find shallow old ice, and one of the toughest places to spend a field season,” said Sarah Shackleton of Woods Hole Oceanographic Institution. 

COLDEX is currently in a “friendly competition” with other global teams to push the ice core record past its previous 800,000-year limit (a European team recently reached 1.2 million years).

The ultimate goal of the ongoing research is to reconstruct historical levels of atmospheric greenhouse gases and ocean heat content. 

Scientists hope the environmental history locked in this ancient ice will offer guidance for the future.

Past climate shifts could help decode critical processes and potential “tipping points.” 

Experts state that high greenhouse gas levels existed in past eras, but the unprecedented rapid rise in these warming gases due to human activity over the last 150 years is pushing the planet into uncharted climate territory.

The findings were reported in the Proceedings of the National Academy of Sciences.
