Xiaomi teases a double-folding smartphone… ohhai digital triptych!

Published

on

China’s Xiaomi has become the latest smartphone maker to tease a folding smartphone, dropping the below video clip of its president and co-founder, Bin Lin, fondling the device on social media today.

The twist is the tablet does not have a single center parting but rather two folds that divide it into three panels, with Xiaomi claiming in a tweet: “It is the world’s first ever double folding phone.”

The video shows Bin contemplating a tablet-sized touchscreen device before quickly turning it on its side, taking it into landscape orientation, where he performs the party trick — folding two panels of screen, one at each side, back behind the tablet to form a slightly chunky looking phablet.

The video is edited so it cuts from front view to back at the moment of the fold so the actual folding action is not seen from the front. But from the back the two folded wings go dark after being folded.

When the video cuts back to the front there’s a slight spinning of the screen, as the software appears to grapple momentarily with the new form factor, before it stablizes in portrait orientation.

The phablet form of the device resembles the bezel-less “infinity display” design of a handset like the 2018 Samsung Galaxy S8 — albeit more squat looking than the tall 18.5:9 aspect ratio of the S8.

Xiaomi’s tweet teaser does not include any details about how near (or indeed far off) a market launch of the device might be. We’ve reached out to the company with questions about the prototype and any launch plans.

Update: A spokesman pointed us to a post on Bin’s Weibo account where he asks his followers for feedback on the prototype, and suggests Xiaomi is still weighing up whether to bring the folding phone to market, writing: “If you like it, we will consider making a mass production machine in the future.”

He also asks for name suggestions, saying Xiaomi is toying with two: Xiaomi Dual Flex or Xiaomi MIX Flex.

“This symmetrical double-folded form perfectly combines the experience of the tablet and mobile phone, which is both practical and beautiful,” he writes [translated via Google Translate], saying building the prototype entailed “conquering a series of technical problems such as flexible folding screen technology, four-wheel drive folding shaft technology, flexible cover technology, and MIUI adaptation.”

“We made the first folding screen mobile phone, which should be the world’s first double folding mobile phone,” he adds, again taking a tentative tone vis-à-vis a potential launch time frame.

In recent months a handful of folding smartphone prototypes have been demoed by mobile makers, including a booklet-style folding slab from Samsung — trailed as incoming for years but finally teased officially last fall — which also appears to transforms into a rather chunky handset.

An invite to a February 20 Samsung launch event for the forthcoming Galaxy S10, sent out to press two weeks ago, also included a conspicuous centerfold in its graphic teaser. Ergo, a commercial launch from Samsung looks imminent.

While, at CES, a little known Chinese OEM called Royole beat others to the punch by showing off a folder in the flesh. In tablet form the Android-powered FlexPai, as the device was christened, is 7.8-inches. But once folded in half the gizmo is left with an unsightly gap between the screen pieces, bulking up the resulting smartphone.  

Xiaomi’s triptych looks to offer a more pleasing design for handling the inevitable air gap created by a folding screen by concealing the ends in the middle of the dual folded panels. Side tucks certainly look more visually pleasing.

That said, two folds could mean a higher risk of screen problems — if the folding mechanism isn’t robust enough to handle lots of bending back and forth.

It’s also far from clear whether consumers will generally take to folding phones, or snub them as fiddly and gimmicky.

In recent years smartphone design has converged around a phablet-sized touchscreen and little else. So adding any fresh mechanical complication is a bit of a risk given how smooth and hermetically sealed smartphones have otherwise become.

But a clutch of Android OEMs are going to try their luck, regardless. And with a saturated smartphone market, stalled growth and competition fiercer than ever, you can see why they’re pushing the boat out — or, well, bending the screen back — to try to stand out.

Tesla shows off underwhelming human robot prototype at AI Day 2022

Tesla

Today at Tesla’s “AI Day” press event, Tesla CEO Elon Musk unveiled an early prototype of its Optimus humanoid robot, which emerged from behind a curtain, walked around, waved, and “raised the roof” with its hands to the beat of techno music.

It was a risky reveal for the prototype, which seemed somewhat unsteady on its feet. “Literally the first time the robot has operated without a tether was on stage tonight,” said Musk. Shortly afterward, Tesla employees rolled a sleeker-looking Optimus model supported by a stand onto the stage that could not yet stand on its own. It waved and lifted its legs. Later, it slumped over while Musk spoke.

The entire live robot demonstration lasted roughly seven minutes, and the firm also played a demonstration video of the walking Optimus prototype slowly picking up a box and putting it down, slowly watering a plant, and slowly moving metal parts in a factory-like setting—all while tethered to an overhead cable. The video also showed a 3D-rendered view of the world that represents what the Optimus robot can see.

Tesla first announced its plans to built a humanoid robot during its AI Day event in August of last year. During that earlier event, a human dressed in a spandex suit resembling a robot and did the Charleston on stage, which prompted skepticism in the press.

At the AI Event today, Musk and his team emphasized that the walking prototype was an early demo developed in roughly six months using “semi-off the shelf actuators,” and that the sleeker model much more closely resembled the “Version 1” unit they wanted to ship. He said it would probably be able to walk in a few weeks.

Goals of the Optimus project include high-volume production (possibly “millions of units sold,” said Musk), low-cost (“probably less than $20,000”), and high-reliability. Comparing the plans for Optimus to existing humanoid robots from competitors, Musk also emphasized that the Optimus robot should have the brains-on-board to work autonomously, citing Tesla’s work with its automotive Autopilot system.

Shortly afterward, Musk handed over the stage to Tesla engineers that gave jargon-heavy overviews about developing the power systems, actuators, and joint mechanisms that would make Optimus possible, replete with fancy graphs but with few concrete specifics about how they would apply to a shipping product. “We are carrying over most of our design experience from the car to the robot,” said one engineer, while another engineer said they drew much of their inspiration from human biology, especially in joint design.

Earlier in the demonstration, Musk said that they were having the event to “convince some of the most talented people in the world to come to Tesla and help bring this to fruition.” Musk also emphasized the public nature of Tesla several times, mentioning that if the public doesn’t like what Tesla is doing they could purchase stock and vote against it. “If I go crazy, you can fire me,” he said.

High-severity Microsoft Exchange 0-day under attack threatens 220,000 servers

Published

on

Microsoft late Thursday confirmed the existence of two critical vulnerabilities in its Exchange application that have already compromised multiple servers and pose a serious risk to an estimated 220,000 more around the world.

The currently unpatched security flaws have been under active exploit since early August, when Vietnam-based security firm GTSC discovered customer networks had been infected with malicious webshells and that the initial entry point was some sort of Exchange vulnerability. The mystery exploit looked almost identical to an Exchange zero-day from 2021 called ProxyShell, but the customers’ servers had all been patched against the vulnerability, which is tracked as CVE-2021-34473. Eventually, the researchers discovered the unknown hackers were exploiting a new Exchange vulnerability.

Webshells, backdoors, and fake sites

“After successfully mastering the exploit, we recorded attacks to collect information and create a foothold in the victim’s system,” the researchers wrote in a post published on Wednesday. “The attack team also used various techniques to create backdoors on the affected system and perform lateral movements to other servers in the system.”

On Thursday evening, Microsoft confirmed that the vulnerabilities were new and said it was scrambling to develop and release a patch. The new vulnerabilities are: CVE-2022-41040, a server-side request forgery vulnerability, and CVE-2022-41082, which allows remote code execution when PowerShell is accessible to the attacker.

“​​At this time, Microsoft is aware of limited targeted attacks using the two vulnerabilities to get into users’ systems,” members of the Microsoft Security Response Center team wrote. “In these attacks, CVE-2022-41040 can enable an authenticated attacker to remotely trigger CVE-2022-41082.” Team members stressed that successful attacks require valid credentials for at least one email user on the server.

The vulnerability affects on-premises Exchange servers and, strictly speaking, not Microsoft’s hosted Exchange service. The huge caveat is that many organizations using Microsoft’s cloud offering choose an option that uses a mix of on-premises and cloud hardware. These hybrid environments are as vulnerable as standalone on-premises ones.

Searches on Shodan indicate there are currently more than 200,000 on-premises Exchange servers exposed to the Internet and more than 1,000 hybrid configurations.

Wednesday’s GTSC post said the attackers are exploiting the zero-day to infect servers with webshells, a text interface that allows them to issue commands. These webshells contain simplified Chinese characters, leading the researchers to speculate the hackers are fluent in Chinese. Commands issued also bear the signature of the China Chopper, a webshell commonly used by Chinese-speaking threat actors, including several advanced persistent threat groups known to be backed by the People’s Republic of China.

GTSC went on to say that the malware the threat actors eventually install emulates Microsoft’s Exchange Web Service. It also makes a connection to the IP address 137[.]184[.]67[.]33, which is hardcoded in the binary. Independent researcher Kevin Beaumont said the address hosts a fake website with only a single user with one minute of login time and has been active only since August.

Kevin Beaumont

The malware then sends and receives data that’s encrypted with an RC4 encryption key that’s generated at runtime. Beaumont went on to say that the backdoor malware appears to be novel, meaning this is the first time it has been used in the wild.

People running on-premises Exchange servers should take immediate action. Specifically, they should apply a blocking rule that prevents servers from accepting known attack patterns. The rule can be applied by going to “IIS Manager -> Default Web Site -> URL Rewrite -> Actions.” For the time being, Microsoft also recommends people block HTTP port 5985 and HTTPS port 5986, which attackers need to exploit CVE-2022-41082.

Microsoft’s advisory contains a host of other suggestions for detecting infections and preventing exploits until a patch is available.

Bruce Willis sells deepfake rights to his likeness for commercial use

Published

Bruce Willis has sold the “digital twin” rights to his likeness for commercial video production use, according to a report by The Telegraph. This move allows the Hollywood actor to digitally appear in future commercials and possibly even films, and he has already appeared in a Russian commercial using the technology.

Willis, who has been diagnosed with a language disorder called aphasia, announced that he would be “stepping away” from acting earlier this year. Instead, he will license his digital rights through a company called Deepcake. The company is based in Tbilisi, Georgia, and is doing business in America while being registered as a corporation in Delaware.

In 2021, a deepfake Bruce Willis appeared in a Russian cell phone commercial for MegaFon.

Deepcake obtained Willis’ likeness by training a deep learning neural network model on his appearances in blockbuster action films from the 1990s. With his facial appearance known, the model can then apply Willis’ head to another actor with a similar build in a process commonly called a deepfake. Deepfakes have become popular in recent years on TikTok, with unauthorized deepfakes of Tom Cruise and Keanu Reeves gathering large followings.

In a statement on Deepcake’s website, Bruce Willis reportedly said:

I liked the precision of my character. It’s a great opportunity for me to go back in time. The neural network was trained on [the] content of Die Hard and Fifth Element, so my character is similar to the images of that time.

With the advent of the modern technology, I could communicate, work, and participate in filming, even being on another continent. It’s a brand new and interesting experience for me, and I [am] grateful to our team.

According to Deepcake’s website, the firm aims to disrupt the traditional casting process by undercutting it in price, saying that its method “allows us to succeed in tasks minus travel expenses, expensive filming days, insurance, and other costs. You pay for endorsement contract with the celeb’s agent, and a fee for Deepcake’s services. This is game-changingly low.”

While the Telegraph report claims that Willis is “the first Hollywood star to sell his rights to allow a ‘digital twin’ of himself to be created for use on screen,” Ars Technica could not verify that claim outside of the context of a first license with the firm Deepcake. Evidence suggests that a similar licensing precedent exists—in Hollywood, deepfakes have already been used in several Star Wars films and TV shows, for example.

Looking deeper, the concept of having a “digital twin” isn’t new to Willis, either. In 1998, he starred in a PlayStation video game called Apocalypse that involved digitizing his face and capturing the motion of his body as he acted out scenes. Still, it’s notable to see an aging actor sidelined by illness who is willing to volunteer a digital double to work for him. James Earl Jones did so recently with his voice for Darth Vader. It’s possible we’ll see much more of this as deepfake technology improves.
