  • FBI Arrests Man Accused of Using Steam Games To Drain Victims' Crypto Wallets
    by BeauHD on 17/07/2026 at 6:00 pm

    The FBI arrested a Florida man accused of uploading fake Steam games containing malware that stole passwords, data, and cryptocurrency wallet credentials from victims. Prosecutors say the scheme infected about 8,000 people, compromised roughly 80 crypto wallets, and stole at least $220,000 through games that appeared legitimate but secretly carried malware. TechCrunch reports: On Tuesday, the FBI arrested Zyaire Wilkins, a 21-year-old Florida resident and student. On Wednesday, prosecutors accused him and a number of unnamed co-conspirators of hacking crimes. Over the past two years, Wilkins and his partners allegedly published several malware-laden video games on Steam, including BlockBlasters, Dashverse, Lampy, Lunara, and PirateFi. Using that malware, says the FBI, Wilkins and his accomplices infected around 8,000 victims, and then hacked around 80 cryptocurrency wallets to steal at least $220,000 worth of crypto. Wilkins and the others marketed their malicious video games on Discord, LinkedIn, and Telegram, according to the authorities. [...] After the FBI identified another person involved in the crimes, according to the complaint, federal agents interviewed them. The unnamed person said they worked with other people to raise money to launch and market the malicious games in return for sharing some of the stolen cryptocurrency. The FBI identified a specific crypto account involved in the scheme, and then traced cryptocurrency payments made with that account to buy several gift cards, including for UberEats. After subpoenaing Uber, the feds were able to see that the gift cards were linked to an account that made deliveries to Wilkins, who went by the nickname Sibel.eth online, according to the complaint. The feds then got a search warrant for Wilkins' residence, where they seized his MacBook laptop, cellphones, other devices, and digital wallets. According to the complaint, he refused to speak or answer any questions. Read more of this story at Slashdot.

  • Meta In Talks To Lease Computing Power To Anthropic In Potential $10 Billion Deal
    by BeauHD on 17/07/2026 at 5:33 pm

    Anthropic is reportedly in very early talks to lease computing power from Meta in a potential deal worth around $10 billion. The discussions follow Anthropic's recent compute deal with SpaceX and come as Meta explores selling excess AI capacity as part of a broader push to turn its massive infrastructure spending into a cloud business. CNBC reports: Access to enough AI chips remains a challenge for firms like Anthropic, which places usage limits on its most advanced models like Fable. [...] Meta could spend as much as $145 billion on capital expenditures, including for AI infrastructure, in 2026. Last October, Zuckerberg said that companies are regularly "asking if we have compute that they could buy from us at some premium to what we've bought it at." Read more of this story at Slashdot.

  • Apple Sends Legal Letters To Dozens of OpenAI Employees
    by BeauHD on 17/07/2026 at 4:00 pm

    An anonymous reader quotes a report from MacRumors: Apple has reportedly sent legal letters to dozens of former Apple employees now working at OpenAI, telling them to preserve potentially relevant documents and communications as it continues to pursue its trade secret lawsuit against the AI company. The Financial Times (paywalled) reports that Apple has targeted around 40 former employees with legal preservation letters, acting on its belief that the alleged misappropriation of confidential information may extend beyond the individuals named in its original complaint. The development follows Apple's lawsuit filed last week against OpenAI, in which the company alleges a coordinated effort to obtain confidential information relating to its hardware engineering and product development. Apple claims OpenAI recruited key engineers, including former Apple executives Tang Tan and Chang Liu, and benefited from proprietary designs, manufacturing processes, and other trade secrets. Tan is OpenAI's Chief Hardware Officer and a 24-year Apple veteran who led product design, while Liu is on the hardware team at OpenAI after working as a senior system electrical engineer at Apple.

  • Kalshi Flags Trump's Teleprompter Operator For Alleged Insider Trading
    by BeauHD on 17/07/2026 at 3:00 pm

    ABC News reports that White House teleprompter operator Gabriel Perez allegedly made more than $100,000 betting on Kalshi markets tied to what President Trump would say in speeches, using his access to prepared remarks and last-minute edits. ABC News reports: According to the sources, Kalshi alerted its regulator, the Commodity Futures Trading Commission (CFTC), to the suspicious activity on its "Mentions" market, where users can bet on whether specific words, phrases or topics are uttered during a public speech. "Our surveillance team promptly flagged and referred these trades to the CFTC, and we are cooperating and assisting regulators," Kalshi's head of enforcement, Bobby DeNault, said in a statement provided to ABC News. White House Press Secretary Karoline Leavitt told reporters Thursday afternoon, following ABC News' report, that Perez has been put on unpaid administrative leave. Leavitt said she spoke with President Trump about it, and he thought it was a "disgrace" and made the decision himself to put Perez on unpaid leave. Leavitt said she was unaware of any other White House staffers who have made such trades. "The White House has strict ethics guidelines that we expect all staffers and officials to follow," said White House spokesperson Davis Ingle when contacted by ABC News. In addition to February's State of the Union address, sources said CFTC investigators discovered that Perez placed bets on more than a dozen Trump speeches over a three-month period, including a December primetime address, a January speech at the World Economic Forum in Davos, Switzerland, and Trump's remarks in March during a Medal of Honor ceremony.

  • Microsoft Restores Player's 25-Year-Old Account After Nuking It Due to Hacker
    by BeauHD on 17/07/2026 at 11:00 am

    Microsoft restored streamer Joshua Khane's 25-year-old Xbox and OneDrive account after it was compromised by a hacker and then suspended, putting years of personal data, baby photos, and thousands of dollars in games at risk. IGN reports: While he was "extremely happy" and thanked Microsoft for its help recovering his account and all the invaluable information therein, he levied some criticisms toward the brand for its initial response, claiming it had told him the suspension was "irreversible" at first. "It's unfortunate that such a big company can bring back your account if you ask them to," he said. "The way it all went, to me, is a little bit shady, because it's not that they can't bring back your account -- they won't bring back your account if you're a nobody." Khane credited the community for making his story go viral and bringing it to Microsoft's attention, but felt that without their help, he would have been up a creek without a paddle. He also tied the situation to the growing conversation surrounding digital ownership, comparing it to Sony's decision to stop printing physical game discs starting January 2028.

  • Astronomers Find an Atmosphere On a Nearby Earth-Like Planet
    by BeauHD on 17/07/2026 at 7:00 am

    Astronomers have directly detected helium in the atmosphere of LHS 1140 b, a rocky exoplanet 48 light-years away that sits in its star's habitable zone. The finding marks the first confirmed atmosphere around a rocky, Earth-like planet in the habitable zone, strengthening the case that some planets orbiting red dwarfs can retain atmospheres and potentially support liquid water. "We have actually detected directly the helium present in the atmosphere itself, and that's the first direct detection for any rocky exoplanet, which is really exciting ... and then there's this added bonus that it's in the habitable zone, which is super exciting for astrobiology and habitability and searching for life," lead author Collin Cherubim, who recently earned his Ph.D. from Harvard University, told Space.com. "It feels kind of surreal." From the report: This exoplanet, or planet outside of our solar system, was first discovered in 2017 by a team led by astronomer Jason Dittmann who is now a co-author on this new discovery. "This planet was found like 10 years ago, and we're just now saying, okay, that's an atmosphere," Dittman told Space.com. "We're slowly narrowing the gap and checking these boxes ... we're finding a planet that's rocky, a planet that's of the right temperature and now ... it's like okay, we finally found one that has an atmosphere." And being a rocky planet, "there's definitely a surface ... it's made of rocks," Dittman said. What does the planet's surface look like? We can't say yet, but the researchers who found this planet's atmosphere think there's a good chance it could have water. While it orbits a red dwarf star, which is smaller and cooler than the sun, it orbits closer than we do to our star, maintaining a temperature that keeps the planet in the "Goldilocks zone" where liquid water could exist on its surface. "It probably also has a lot of water," Cherubim said. "If it has some amount of atmosphere that can provide a bit of a greenhouse effect, which we know that it does now ... it will very likely be what we consider to be habitable conditions on Earth, and conditions that would likely support liquid water." So is it Earth-like? While it's certainly not an Earth copy, this planet can be considered Earth-like in two main ways, Cherubim shared. One: its overall composition. The planet is rocky, likely with an iron core and (now we know) it has an atmosphere. And two: the planet's temperature is just right for liquid water, which is necessary for life at least as far as we understand it on our planet. [...] "I'm not claiming this planet has life," Cherubim made clear. With further investigation, scientists could better understand what else might be in this planet's atmosphere, and they could confirm if it has water. Further observations might not be able to confirm habitability or identify any life on the planet, but they could at least help us to better understand planets like this. The findings have been published in the journal Science. Read more of this story at Slashdot.
