French govt messaging service breached in account hijacking attack

Published

on

France

DINUM, the digital affairs directorate of the French government, warned that hackers used a hijacked user account to breach Tchap, the French government’s encrypted messaging platform.

Developed in-house by DINUM in collaboration with ANSSI (the French Cybersecurity Agency) in 2018, Tchap is an instant messaging service and collaboration tool based on the decentralized Matrix protocol, designed exclusively for the French public sector.

Tchap has now reached over 300,000 monthly users and over 500,000 downloads on Google’s Play Store after Prime Minister François Bayrou mandated the use of Tchap and banned foreign apps for work communications for all civil servants in early August 2025.

DINUM revealed on Monday that ANSSI detected a Tchap breach on Sunday and said that a threat actor gained access to the secure instant messaging platform using a compromised user account.

The French digital affairs directorate has also alerted France’s data protection authority, the CNIL, to the incident due to the potential exposure of personal data shared by some users in conversations that the attacker could access, and has alerted all Tchap users, reminding them that public chat rooms are accessible to any user and are not encrypted.

“At this stage, the account originating the malicious requests has been identified. It was immediately blocked to remove the attacker’s persistent access and allow for a thorough analysis of the data they were able to access. The investigation continues, including the study of event logs, to identify the conversations that the attacker was able to access and the nature of the exfiltrated data,” DINUM said in a Monday press release.

“A message has been sent to all Tchap users reminding them that a public chat room can be found and joined by any user and that its content is not encrypted. In accordance with Tchap’s terms of service, no personal, sensitive, or confidential information should be exchanged in public chat rooms: such exchanges should be reserved for private chat rooms.”

While the DINUM has not shared any further details regarding this breach, a threat actor claimed responsibility for the incident over the weekend, shared a sample of stolen files, and said they gained access to the platform following a social engineering attack.

​”I social engineered a valid account on the education shard (matrix.agent.education.tchap.gouv.fr). Everything below is what that one account could reach, other shards will have more,” they said.

​They claim to have stolen hardcoded LDAP credentials allegedly leaked via a PowerShell script shared by a French tax authority regional director and over 13.5GB of documents and media files shared by public servants using the Tchap service.

The threat actors also allegedly scraped nearly 650,000 messages and information on over 73,000 accounts, including email addresses, organization information, meeting links, and account and device metadata.

“Every file ever shared on Tchap, on any shard, is downloadable without a token,” they added. “The media IDs come from the messages. Once you have a message with a media URL you can pull the file freely regardless of which shard hosts it.”

BleepingComputer reached out to DINUM with questions about the incident, but a response was not immediately available.

‘Black Panther 3’ Introduces T’Challa Jr. at Marvel’s Comic-Con Presentation

Published

on

A new, adult T’Challa is joining the Marvel Cinematic Universe. Kevin Feige hit the stage for Marvel’s Hall H Comic-Con showing on Saturday and, toward the end, gave the audience an update on Black Panther 3. Director Ryan Coogler and actors Winston Duke and Letitia Wright were on hand to welcome David Jonsson to the MCU, who will play T’Challa’s son, T’Challa Jr.

Jonsson has appeared in films such as Alien: Romulus and The Long Walk. While no official title has been shared, Feige revealed that Black Panther 3 is due to hit theaters Dec. 15, 2028.

Coogler, who’s writing and directing the next installment of the series, has reportedly begun production. He helmed the first two Black Panther movies, which brought the late Chadwick Boseman to the screen as the royal hero. T’Challa Jr. appeared as a child at the end of Black Panther 2, and the character will clearly be aged up for the new movie.

It’s rumored that X-Men character Storm will be in the mix, who has a history with Wakanda (and Black Panther) in the comic books. With a standalone X-Men movie in the works and renewed enthusiasm for the mutants since the release of the animated X-Men ‘97 series, an interconnected storyline would make sense for the MCU.  Also rumored to appear in the superhero film is Brother Voodoo, a sorcerer-superhero (like Doctor Strange) who also works with the dead.

Black Panther: Wakanda Forever (aka Black Panther 2) introduced Tenoch Huerta’s Namor and his underwater kingdom into the MCU, and he’s slated to surface in this year’s Avengers: Doomsday, along with the new Black Panther, Shuri (played by Wright).

China fines Trip.com $765 million for abusing its dominance in hotel bookings

TL;DR

China fines Trip.com $765 million for forcing hotel partners into exclusive deals and controlling their pricing

China’s market regulator fined Trip.com Group $765 million on Saturday after concluding that the country’s largest online travel platform abused its dominant market position. The State Administration for Market Regulation said Trip.com used its traffic allocation algorithms, platform rules and technology to restrict hotel operators from listing on competing services and to control the prices they could charge. The penalty, totaling roughly five billion yuan, includes confiscated gains, a separate fine and an order to refund hotel security deposits.

SAMR launched the investigation in January after receiving complaints that Trip.com was forcing hotel partners into exclusive arrangements and demanding they offer their lowest online rates only on its platform. The regulator found the company had engaged in these practices since 2020, leveraging its control of about 56 percent of China’s online travel market to pressure operators who depended on it for visibility and bookings. Trip.com said in a statement on its official WeChat account that it accepts the decision and will implement rectification measures.

The fine is the largest antitrust penalty SAMR has imposed on a single Chinese tech company since it fined Alibaba 18 billion yuan in 2021 for similar abuse of market dominance. That case, which forced Alibaba to abandon exclusive dealing arrangements with merchants, set the template for Beijing’s broader crackdown on platform monopolies. The Trip.com penalty signals that the regulator’s appetite for enforcement has not waned, even as Beijing has shifted its messaging toward calibrated oversight rather than blanket crackdowns.

The case also reflects regulators’ concern that fierce competition among online travel platforms has been squeezing hotel operators’ margins and contributing to deflationary pressure in parts of the Chinese economy. Beijing has been rewriting its e-commerce law to bring platform companies under tighter domestic oversight, with draft amendments published earlier this month proposing expanded regulatory tools for overseeing algorithms, traffic rules and pricing practices. Trip.com’s penalty lands squarely within that framework.

Founded in 1999, Trip.com operates through brands including Ctrip and Skyscanner and has grown into the world’s largest online booking platform by transaction volume. Its dominance in China gave it leverage to dictate terms to hotel partners, but that same market power made it a regulatory target as Beijing moved to curb what it views as monopolistic behaviour across its technology sector. The company has been ordered to undertake a comprehensive rectification plan, though the specifics of those changes have not yet been disclosed.

The company anticipates revenue in the third quarter of 2026 to hit between $15.8bn and $16.8bn, and projects a gross margin of 41pc.

The company’s share price increased by up to 4pc during trading hours yesterday following publication of its financial results.

Intel is estimated to have reduced its headcount by more than 35,000 employees since 2024, with major cuts announced in both 2024 and 2025.

Earlier this month, the company announced a major investment in its Kildare, Ireland facility, where Intel intends to spend €5bn on the Leixlip campus.

When a 1,139-Horsepower Porsche Cayenne Turbo Electric Ran Beneath the World’s Biggest Plane

Published

on

Porsche Cayenne Turbo Electric vs Stratolaunch Roc Largest Aircraft
Mojave Air and Space Port sits in the high desert where the air stays dry and the runways stretch long enough for machines that refuse ordinary limits. On a recent morning there, a prototype Porsche Cayenne Turbo Electric rolled into position under the shadow of Stratolaunch’s Roc. Six jet engines sat silent for the moment. The SUV waited between the twin fuselages of an aircraft whose wings span 385 feet.



Roc is designed to carry enormous payloads into the sky for hypersonic experiments and spacecraft launches. Even when empty, with its six Pratt & Whitney engines cranking out a staggering 340,500 pounds of thrust, the plane can take off at a maximum weight of 1.3 million pounds, which is enormous when compared to modern airliners. Porsche’s new Cayenne has just arrived with a pair of electric motors that provide 1,139 horsepower and 1,500 Nm of torque, an outstanding spec sheet. It takes 2.4 seconds to accelerate from 0 to 60 mph, which is incredible. When things get hairy, the Cayenne has active aerodynamics and, as an option, very heavy-duty carbon-ceramic brakes ready to bail it out.

Stratolaunch’s engineers had been monitoring the airflow near Roc. During takeoff and landing, a strange small pocket of still air emerges directly behind the main landing gear and just ahead of the tail, and this bubble follows the plane. In principle, a car that was both fast and stable enough could simply sit in the center of this bubble and remain there. That concept evolved into a hunch, which led to a strategy. Straotlaunch had a volunteer driver lined up, none other than former Porsche factory driver Patrick Long. He was joined by crew chiefs Shauntel Williams and John McKinney, who were keeping radio contact with the flight deck crew, as well as Orlando Bloom and a lucky automotive journalist Mat Watson.

The first run began with Long carefully positioning the Cayenne in just the perfect area, applying almost little throttle at all. Roc’s engines burst into life. At roughly 100 mph, he put the Cayenne into boost mode and flew after the plane, matching its stride for stride. The SUV remained right beneath the plane’s gear as it pulled away, and it was apparent as day that the vehicle had the stability to endure the turbulence when the engines lowered. Long later described how, when the engines began to descend after takeoff, he felt a great jolt and the car continued to go as if nothing had happened. He glanced down at the speedometer, and holy moly, the needle was over 170 before he yanked his foot off the throttle and slapped on the carbon-ceramic brakes to reduce the speed before the runway ended.

Landing, on the other hand, is a completely other story since time is everything. Roc is massive, making visual cues scarce, so Long had to merge onto the runway at precisely the exact moment, skillfully maneuvering between the plane’s fuselage such that the automobile appeared under the gear just as the plane touched down. The Stratolaunch crew commanders were right there in the cabin, keeping Long on track with continuous radio calls. The pattern repeated itself over two takeoffs and landings, with all four landings going off as planned. The Cayenne utilized only 13 percent of its battery charge the entire time.

Patrick Long described it as one of the most focused moments he’d ever had in a car. He trusted the data, the automobile, and the pilots. And it appears that the trust paid off, since Jonathan Bearce, the plane’s principal test pilot, was also impressed. From the cockpit, all he could see was a Cayenne-sized black hole, but the footage subsequently revealed it was spot on. Bearce even got to drive the thing himself later on, and he stated it accelerated so quickly that it surprised him. Overall, it was an eye-opening exercise in demonstrating the importance of precision over raw speed.

Contagious Cancer Found in North American Catfish

Published

on

The idea that cancer could behave like a contagious disease may seem absurd; in humans, cancer cannot be transmitted from one person to another. Yet nature is still full of surprises. In exceptional cases, cancer cells themselves can pass from one individual to another and continue to multiply in a new host. This rare phenomenon has been detected in animals such as dogs, Tasmanian devils, and some species of mollusks, and it seems we can add one more to that exclusive club: catfish.

An international team of researchers has identified a transmissible melanoma in the brown catfish (Ameiurus nebulosus)—the first documented case in fish and also the first recorded in a freshwater ecosystem. Their findings were reported this month in the journal Nature.

An Impossible Pattern

The story began in 2012, when fishermen and biologists detected an unusually high number of catfish with black lesions in Lake Memphremagog, a body of water straddling Vermont and Quebec. Previous studies revealed that these spots were malignant melanomas, and that between 23 percent and 37 percent of the specimens examined had these tumors—an unusually high incidence for this species.

“That was surprising,” said Julie Dragon, a researcher at the University of Vermont and co-lead author of the study. “We wanted to know how a bottom-dwelling fish was getting a cancer we associate with exposure to too much sunlight.”

Initially, it was thought that the cause might be some toxic substance or a pathogen linked to pollution. One suspicion was that the flooding caused by Tropical Storm Irene in 2011 had degraded water quality by washing environmental pollutants into the lake. There were also concerns about the health of the lake, which supplies drinking water to more than 175,000 people. However, initial genetic analyses began to point in an unexpected direction.

It was then that the researchers wondered whether the tumors were descended from a single original cancer that had learned to spread among individual fish, rather than arising independently in each fish.

To test this unusual hypothesis, the team sequenced the complete genomes of tumors and healthy tissues from affected fish, and compared the data with that from healthy specimens from different populations.

The results indicated that the tumor cells from different fish were much more closely related to one another than to the animals in which they developed. In other words, the tumors shared their own genetic identity, distinct from that of their hosts. Furthermore, hundreds of thousands of genetic variants appeared repeatedly in the tumors but were absent from the healthy tissues of the same fish.

Such a pattern would be virtually impossible if each melanoma had arisen independently. By way of comparison, the researchers analyzed hundreds of human melanomas and found that nearly all of their mutations were unique to each patient. In contrast, most of the mutations present in the tumors of these fish were shared by numerous individuals—a hallmark of a transmissible clonal cancer.

The 20 Percent Rule For Solar Panels Can Help You Save Money In The Long Run

Published

on

Building your system with some extra capacity makes managing it a bit easier.

If you own a solar system, there’s a good chance you’ll have heard of the 20 percent rule. And if you haven’t, it can be explained easily enough. “n essence, it means estimating how much electricity your house needs, then sizing your solar panel system so that it produces roughly 20 percent more energy than your home uses. Think of it this way: if your home uses 40kWh per day, your panels should be producing 48kWh. But what are the benefits of having this extra energy at your disposal?

It really boils down to savings and guarding against less than optimal solar conditions. Having a system that produces 20 percent more energy should ensure your house has all the power it needs, even during dimmer winter months. There’s also a cost benefit, whereby any excess energy you don’t use can be sent back to the grid resulting in potential banked up credit from your energy supplier. Incentive programs also exist that provide certain discounts the more energy that your home produces. So yes, the 20 percent rule of solar panels can definitely save you money, but it’s not a guarantee of instant savings.

Advertisement

When does the 20 percent buffer come in handy?

One of the main benefits to the 20 percent rule is offering you extra power for those times when your household’s electricity output is higher than normal. Seasonal variations are a big reason you should consider installing additional panels. The summer months are when you should most feel the benefits. In an era of skyrocketing temperatures where heat records are regularly being broken, it’s only natural people are going to run air conditioning systems frequently during summer. In baking conditions, many folks will appreciate that extra solar cover.

Conversely, having more power to tap into can also come in handy during winter. On especially cold days, that additional energy capacity is going to be appreciated if you’re regularly running your heat for hours on end. More generally, owners of solar panel systems that adhere to the 20 percent rule will find it easier to power their homes on dimmer days when the sun’s rays may be obscured. And in case you’re wondering, here’s what happens when solar panels die.

Advertisement

Why should I spend more on solar if I don’t always need it?

It’s best to think of the upsides of the 20 percent rule in the long term. While your current panelling may service your energy needs perfectly well today, that’s not to say needs won’t change over the lifespan of your system. Lifestyle changes could easily impact your electricity usage going forward and extra panels could well prove worthwhile if you, say, suddenly start working from home more often. Equally, extra solar cover will be appreciated if you install an air conditioning system in your home or buy an EV.

We now live in a world where scientists at Oxford have created a new light-absorbing material that can turn everyday objects into solar panels. That’s great, but such advances probably won’t save you money anytime soon. What could bag you some savings is the 20 percent rule. Depending on your energy provider, any excess power your system produces that your home doesn’t use can be sent back to the grid, netting you credit from your supplier. In turn, this can help lower future bills, and over the longer term could provide serious savings. Just bear in mind that solar buyback rates can vary wildly from state to state in the US, so big discounts aren’t guaranteed.

Does the extra 20 percent really make a difference?

That would be a yes… with caveats. The main benefit to owning a solar panel system that provides 20 percent more power than your household normally consumes is that you’re safeguarding against potential real-world solar losses. It’s been a great time to buy a solar generator for a while now, no question, but there are definitely instances where your generator can do with additional help. If you’re reading this in a particularly rainy part of the US or the UK — where near constant cloud cover in all but summer months is very much a thing — the 20% rule is definitely worth considering, and could net you real savings in the long run. That extra percentage of solar capacity can also help the power losses that naturally occur from less than ideal roofing angles and high panel temperatures.

It’s important to note though, that the 20 percent solar panel rule isn’t going to magically save you 20 percent off your energy bill. Ultimately, it’s best to think of it as a buffer against poor weather conditions or periods where your home’s electricity output is higher than normal.

Nvidia invests $1 billion in Naver and strikes $500 billion deal with SK Group

Published

on

TL;DR

Nvidia is investing $1 billion in Naver and building a $500 billion commercial partnership with SK Group spanning data centers and memory chips

Nvidia will invest $1 billion in South Korean internet company Naver to help finance an AI data center under construction in South Korea, the chipmaker announced late Friday. The funding will allow Naver to more than triple the size of the facility from 55 megawatts to 200 megawatts, with US private equity firm Brookfield agreeing to a nonbinding term sheet to fund up to $9 billion for the project. The site will run on Nvidia’s AI computing hardware.

Separately, Nvidia announced a long-term commercial partnership with SK Group that it described as worth more than $500 billion. The figure includes money Nvidia will spend buying memory chips from SK Hynix, the world’s largest supplier of high-bandwidth memory, as well as purchases by SK Group of Nvidia’s supercomputers. SK Telecom will build more than 2 gigawatts of AI data centers on the Korean Peninsula, with the first facility due to open next year.

The announcements coincide with a visit to Silicon Valley by South Korean President Lee Jae Myung, and additional tech deals between Korean and American companies are reportedly in the works. Nvidia CEO Jensen Huang told Bloomberg Television that South Korea is in a “golden age,” pointing to the country’s booming semiconductor and industrial businesses as reasons to invest. Nvidia will also help SK Hynix design future high-bandwidth memory chips, an effort to guarantee access to the component that remains in short supply because of the global buildout of AI data centers.

Advertisement

The Korea deals are the latest in a year-long investment spree in which Nvidia has committed more than $40 billion to AI equity positions, including $30 billion in OpenAI. Earlier this week the chipmaker signed a separate agreement with Amkor Technology to bolster chip packaging, and it recently completed a trip to Japan that included deals with Toyota and Japanese robotics firms. Critics have described the pattern as circular financing, in which Nvidia invests in companies that then buy its hardware, a structure the chipmaker has replicated with data center operators, neoclouds, and now sovereign AI partners.

Advertisement

For South Korea, the deals represent a bet that its semiconductor industry can remain central to the AI buildout even as geopolitical tensions reshape chip supply chains. Samsung and SK Hynix are the only two companies in the world capable of producing the advanced memory chips that Nvidia’s processors require, and locking in a design partnership with Nvidia gives SK Hynix a structural advantage over its rival. Huang has argued that every country should create its own sovereign AI capability, and South Korea, with its chipmaking expertise and abundant engineering talent, is among the best positioned to do so.

Steam forum ClickFix attacks infect gamers with XMRig cryptominers

Published

on

Steam

Steam discussion forums are being abused in ClickFix attacks that pretend to be fixes for game and computer problems but actually infect devices with cryptominers.

BleepingComputer learned of the campaign from a reader, who told us threat actors are creating random Steam accounts to post what appears to be helpful fixes for people’s posts about games crashing, lost inventory items, and other technical issues.

The threat actors reply to posts, telling other members to open PowerShell as an administrator and run a command to fix the issue. However, when executing the command, it quietly downloads an XMRig miner executable and launches it on the computer.

These types of attacks are known as ClickFix, a social engineering tactic that displays fake errors, verification prompts, or troubleshooting instructions to trick victims into manually executing malicious commands.

Although ClickFix attacks require interaction from the victim, they are effective because they present users with what appears to be both a legitimate solution for a problem they are having.

Since the victim manually launches the command, the attack can also bypass some security protections that would otherwise automatically block executed malicious code.

Fake Windows optimization installs malware

The PowerShell script distributed in the Steam campaign masquerades as a Windows optimization utility named “msf utility \ PC Opt.”

When launched, it displays messages claiming to perform numerous maintenance tasks, including cleaning temporary files, flushing the DNS cache, updating drivers, checking the disk, turning off unnecessary startup items, scanning for malware, repairing the Windows image, and running System File Checker.

The actual malicious activity is hidden in a function named ‘Advanced-Optimization’, which first disables TLS certificate validation and checks that it is running with administrator privileges. If it is not, the script displays an error stating that administrator rights are required and exits.

Once running with elevated privileges, the script creates the ‘C:\Windows\Background’ directory and adds it as an exclusion to Microsoft Defender’s scanning functions.

It also attempts to stop an existing scheduled task named ‘XMRig-[computer name]’ and terminates matching processes named ‘xmrig’ or ‘system’ that are running from the installation directory. It also attempts to delete any XMRig configuration files stored as C:\Windows\Background\config.json.

It is unclear whether this cleanup is intended to remove leftovers from an earlier install of the same malware or another miner already present on the device.

The malware then creates a temporary outbound Windows Firewall rule allowing connections to ‘msfconfig[.]icu‘ over TCP port 443 and downloads the XMRig miner payload from https://msfconfig[.]icu:443/tmp/system.txt into a randomly named temporary file.

Before installing it, the script verifies that the downloaded file is not empty and is a valid executable. If so, it moves the file to C:\Windows\Background\system.exe.

So it launches every time Windows starts, it will create a new scheduled task named “XMRig-[computer name],” that launches the system.exe executable with SYSTEM privileges.

As a general rule, users should never run PowerShell commands provided by unknown users in discussion forums, even when the commands are presented as fixes for a problem they are currently experiencing.

Those who executed the command should check for the ‘C:\Windows\Background’ directory, a Microsoft Defender exclusion for that path, and a scheduled task beginning with ‘XMRig-‘.

If these signs of compromise are detected, you should immediately run an antivirus program to scan for malware and remove anything it finds.

If it does not detect the miner, you should manually stop and remove the XMRig-[computer name] scheduled task, remove the Microsoft Defender exclusion for C:\Windows\Background, and delete the folder and its contents.

Ultimately, it may be safer to reinstall the operating system, as there is no way to know whether the downloaded payload performed additional malicious actions while it was running.
