I didn't expect Google Glass to make a minor comeback at Google I/O 2024, but it did, thanks to Project Astra. 

That's Google's name for a new prototype of AI agents, underpinned by the Gemini multimodal AI, that can make sense of video and speech inputs, and smartly react to what a person is effectively looking at and answer queries about it. 

Described as a "universal AI" that can be "truly helpful in everyday life", Project Astra is designed to be proactive, teachable, and able to understand natural language. And in a video ,Google demonstrated this with a person using what looked like a Pixel 8 Pro with the Astra AI running on it. 

By pointing the phone's camera at room, the person was able to ask Astra to "tell me when you see something that makes sound", to which the AI will flagged a speaker it can see within the camera's viewfinder. From there the person was able to ask what a certain part of the speaker was, with the AI replying that the part in question is a tweeter and handles high frequencies. 

But Astra does a lot more: it can identify code on a monitor and explain what it does, and it can work out where someone is in a city and provide a description of that area. Heck, when promoted, it can even make an alliterative sentence around a set of crayons in a fashion that's a tad Dr Zeus-like.

It can can even recall where the user has left a pair of glasses, as the AI remembers where it saw them last. It was able to do the latter as AI is designed to encode video frames of what it's seen, combine that video with speech inputs and put it all together in a timeline of events, caching that information so it can recall it later at speed. 

Then flipping over to a person wearing the Google Glass 'smart glasses', Astra could see that the person was looking at a diagram of a system on a whiteboard, and figure out where optimizations could be made when asked about them. 

Such capabilities suddenly make Glass seem genuinely useful, rather than the slightly creepy and arguably dud device it was a handful of years ago; maybe we'll see Google return to the smart glasses arena after this. 

Project Astra can do all of this thanks to using multimodal AI, which in simple terms is a mix of neural network models that can process data and inputs from multiple sources; think mixing information from cameras and microphones with knowledge the AI has already been trained on.

Google didn't say when Project Astra will make it into products, or even into the hands of developers, but Google's DeepMind CEO Demis Hassabis said that "some of these capabilities are coming to Google products, like the Gemini app, later this year." I'd be very surprised if that doesn't mean the Google Pixel 9, which we're expecting to arrive later this year.

Now it's worth bearing in mind that Project Astra was shown off in a very slick video, and the reality of such onboard AI agents is they can suffer from latency. But it's a promising look at how Google will likely integrate actually useful AI tools into its future products.

How often do you read through terms and conditions, EULA’s and privacy policies? Although we know we should scour the fine print, it’s something few of us ever bother to do, and certainly not fully.

Non-profit organization Tax Policy Associates wanted to prove how pointless these documents are, and so in February 2024 added a line to its privacy policy, offering a “bottle of good wine” to the first person who spotted the offer and got in touch.

After three months of nobody noticing the addition, the reward was finally found by someone who chanced upon it after looking at several examples of privacy policies online to get an idea of how to create their own.

Not the first time

The organization's head, Dan Neidle, shared the story on X and told the BBC it was "my childish protest that all businesses have to have a privacy policy and no one reads it. Every tiny coffee shop has to have a privacy policy on their website, it’s crazy. It’s money that’s being wasted."

In its coverage, which was the most read story on the site, the BBC pointed out that any company that holds personal data, “including small businesses and charities”, has to have a privacy policy under the UK's General Data Protection Regulation 2018 (GDPR).

This is actually the second time that Tax Policy Associates has made a sneaky addition to its privacy policy. The first time it took four months to be found. "We did it again to see if people were paying more attention and they’re not," Neidle told the BBC.

The writing in the firm's privacy policy has since been changed following the discovery and now says, "We know nobody reads this, because we added in February that we’d send a bottle of good wine to the first person to contact us, and it was only in May that we got a response."

If you're wondering what counts as a "good" bottle of wine in this instance, the answer, according to the BBC, is a Château de Sales 2013/14, Pomerol.

Our ongoing experiment into whether anyone reads website T&Cs continues. We put this in our terms back in February. Just got claimed. pic.twitter.com/N7k3weTuA9May 9, 2024

Academic researchers from multiple universities recently discovered a new Spectre-like method of extracting secrets from modern Intel processors. However, Intel says that the original Spectre mitigation fixes these flaws, too.

A group of researchers from the University of California San Diego, Purdue University, UNC Chapel Hill, Georgia Institute of Technology, and Google, discovered that a feature in the branch predictor called the Path History Register (PHR) can be tricked to expose sensitive data. 

Thus, they dubbed the vulnerability “Pathfinder”.

Extracting AES encryption keys

"Pathfinder allows attackers to read and manipulate key components of the branch predictor, enabling two main types of attacks: reconstructing program control flow history and launching high-resolution Spectre attacks," Hosein Yavarzadeh, the lead author of the paper, told The Hacker News.

"This includes extracting secret images from libraries like libjpeg and recovering encryption keys from AES through intermediate value extraction."

For those with shorter memory, Spectre was a side-channel attack that exploited branch prediction and speculative execution in processors, allowing attackers to read sensitive data in the memory. 

PHR’s job is to keep a record of the last branches taken. It can be fooled to induce branch mispredictions and thus cause a victim program to run unintended code paths. As a result, sensitive data gets exposed. 

In the research paper, the academics demonstrated extracting the secret AES encryption key, and leaking secret images during libjpeg image library processing.

Intel was tipped off in November last year, and released a security advisory addressing the findings, in April this year. In the advisory, Intel said that Pathfinder builds on Spectre v1, adding that the previously released mitigations address this problem, as well.

AMD’s silicon seems to be immune to Pathfinder, the researchers concluded.

BIG-IP Next Central Manager (NCM), a centralized management and orchestration platform for F5’s BIG-IP product family, was vulnerable to two major flaws which allowed malicious actors to take over its managed assets.

The bugs, which have since been patched, are described as an SQL injection vulnerability, and an OData injection vulnerability. 

They are tracked as CVE-2024-26026 and CVE-2024-21793, and are found in the NCM API. By abusing these bugs, threat actors could run malicious SQL statements on vulnerable endpoints from a distance.

Thousands of potential victims

Cybersecurity firm Eclypsium found and reported the flaws, and the researchers also published a proof-of-concept exploit, which demonstrates how a rogue admin account, created by an attacker, remains invisible in the Next Central Manager, granting persistence on the vulnerable endpoint.

"The management console of the Central Manager can be remotely exploited by any attacker able to access the administrative UI via CVE 2024-21793 or CVE 2024-26026. This would result in full administrative control of the manager itself," the researchers explained. "Attackers can then take advantage of the other vulnerabilities to create new accounts on any BIG-IP Next asset managed by the Central Manager. Notably, these new malicious accounts would not be visible from the Central Manager itself."

F5’s NCM allows IT teams to manage devices such as application delivery controllers (ADCs), firewall solutions, and other network appliances. It provides capabilities for configuration management, policy enforcement, monitoring, and reporting across distributed environments. According to Shodan’s figures, there are more than 10,000 F5 BIG-IP devices with open management ports.

F5 also shared a workaround for admins who are unable to install the patch at this time. Per the company’s instructions, restricting Next Central Manager access to trusted users over a secure network sorts out the problem

There is no evidence of in-the-wild exploitation, Eclypsium confirmed.

We love crazy tech projects here at TechRadar Pro - Some of our recent favorites include an enthusiast getting ChatGPT to run on a NAS, and the person who transformed AMD's Ryzen 7 5800X3D processor into a storage device with read-write speeds to rival some of the best SSDs.

The latest idea to cross our desks comes from Gabriel Ferraz, a computer engineer and TechPowerUp's SSD database maintainer, who turned a 512GB QLC SATA III SSD into a 120GB SLC one.

You probably know this, but just as refresher, SLC NAND holds one bit of data per cell, resulting in faster data writing, lower power consumption, and higher cell endurance than QLC NAND which stores four bits per cell. QLC NAND is denser and cheaper, but with the downside of compromised longevity and speed.

3000% endurance increase

Ferraz's idea was to trade capacity for massively improved performance and endurance. He took 512GB a Crucial BX500 SSD which has a Silicon Motion SM2259XT2 controller and NAND flash dies from Micron. Using an app called MPtools for the Silicon Motion SM2259XT2 controller, he identified the precise die used in the SSD and inputted in new die reference numbers.

Was it worth it? Well, while Ferraz lost a lot of drive space, he says “the SSD endurance jumps to 4000 TBW (write cycles), which is about a 3000% increase. Additionally, performance increased as well.”

Ferraz explains his process here, and you can also watch him perform his clever trick in the video below, which includes benchmarking results.
