Contractors With Hacking Records Accused of Wiping 96 Government Databases

Slashdot.org - Fri, 12/05/2025 - 10:15
Two Virginia brothers Muneeb and Sohaib Akhter, previously convicted of hacking the U.S. State Department, were rehired as federal contractors and are now charged with conspiring to steal sensitive data and destroy government databases after being fired. "Following the termination of their employment, the brothers allegedly sought to harm the company and its U.S. government customers by accessing computers without authorization, issuing commands to prevent others from modifying the databases before deletion, deleting databases, stealing information, and destroying evidence of their unlawful activities," the Justice Department said in a Wednesday press release. BleepingComputer reports: According to court documents, Muneeb Akhter deleted roughly 96 databases containing U.S. government information in February 2025, including Freedom of Information Act records and sensitive investigative documents from multiple federal agencies. One minute after deleting a Department of Homeland Security database, Muneeb Akhter also allegedly asked an artificial intelligence tool for instructions on clearing system logs after deleting a database. The two defendants also allegedly ran commands to prevent others from modifying the targeted databases before deletion, and destroyed evidence of their activities. The prosecutors added that both men wiped company laptops before returning them to the contractor and discussed cleaning out their house in anticipation of a law enforcement search. The complaint also claims that Muneeb Akhter stole IRS information from a virtual machine, including federal tax data and identifying information for at least 450 individuals, and stole Equal Employment Opportunity Commission information after being fired by the government contractor. Muneeb Akhter has been charged with conspiracy to commit computer fraud and destroy records, two counts of computer fraud, theft of U.S. government records, and two counts of aggravated identity theft. If found guilty, he faces a minimum of two years in prison for each aggravated identity theft count, with a maximum of 45 years on other charges. His brother, Sohaib, is charged with conspiracy to commit computer fraud and password trafficking, facing a maximum penalty of six years if convicted.

AV1 Open Video Codec Now Powers 30% of Netflix Streaming

Slashdot.org - Fri, 12/05/2025 - 09:14
Netflix says its open AV1 video codec now powers about 30% of all streaming on the platform and is rapidly becoming its primary delivery format thanks to major gains in compression, bandwidth efficiency, HDR support, and film-grain rendering. TVTechnology reports: The blog by Liwei Guo, Zhi Li, Sheldon Radford and Jeff Watts comes at a time when AV2 is on the horizon. [...] The blog revisits Netflix's AV1 journey to date, highlights emerging use cases, and shares adoption trends across the device ecosystem. It noted that since entering the streaming business in 2007, Netflix has primarily relied on H.264/AVC as its streaming format. "Looking ahead, we are excited about the forthcoming release of AV2, announced by the Alliance for Open Media for the end of 2025," said the authors. "AV2 is poised to set a new benchmark for compression efficiency and streaming capabilities, building on the solid foundation laid by AV1. At Netflix, we remain committed to adopting the best open technologies to delight our members around the globe. While AV2 represents the future of streaming, AV1 is very much the present -- serving as the backbone of our platform and powering exceptional entertainment experiences across a vast and ever-expanding ecosystem of devices."

AI Chatbots Can Sway Voters Better Than Political Ads

Slashdot.org - Fri, 12/05/2025 - 08:13
An anonymous reader quotes a report from MIT Technology Review: New research reveals that AI chatbots can shift voters' opinions in a single conversation -- and they're surprisingly good at it. A multi-university team of researchers has found that chatting with a politically biased AI model was more effective than political advertisements at nudging both Democrats and Republicans to support presidential candidates of the opposing party. The chatbots swayed opinions by citing facts and evidence, but they were not always accurate -- in fact, the researchers found, the most persuasive models said the most untrue things. The findings, detailed in a pair of studies published in the journals Nature and Science, are the latest in an emerging body of research demonstrating the persuasive power of LLMs. They raise profound questions about how generative AI could reshape elections.

Satellite Captures the First Detailed Look At a Massive Tsunami

Slashdot.org - Fri, 12/05/2025 - 05:10
NASA and CNES's SWOT satellite captured the first high-resolution, wide-swath image of a major tsunami in the open ocean after the July 2025 Kuril-Kamchatka quake. "Instead of a single neat crest racing across the basin, the image revealed a complicated, braided pattern of energy dispersing and scattering over hundreds of miles," reports Earth.com. "These are details that traditional instruments almost never resolve. They suggest the physics we use to forecast tsunami hazards -- especially the assumption that the largest ocean-crossing waves travel as largely "non-dispersive" packets -- need a revision." From the report: Three takeaways emerge. First, high-resolution satellite altimetry can see the internal structure of a tsunami in mid-ocean, not just its presence. Second, researchers now argue that dispersion -- often downplayed for great events -- may shape how energy spreads into leading and trailing waves, which could alter run-up timing and the force on harbor structures. Third, combining satellite swaths, DART time series, seismic records, and geodetic deformation gives a more faithful picture of the source and its evolution along strike. For tsunami modelers and hazard planners, the message is equal parts caution and opportunity. The physics now has to catch up with the complexity that SWOT has revealed, and planners need forecasting systems that can merge every available data stream. The waves won't get any simpler -- but our predictions can get a lot sharper. The findings have been published in the journal The Seismic Record.

Sugars, 'Gum,' Stardust Found In NASA's Asteroid Bennu Samples

Slashdot.org - Fri, 12/05/2025 - 02:07
NASA's OSIRIS-REx samples from asteroid Bennu have revealed bio-essential sugars, a never-before-seen "space gum" polymer, and unusually high levels of supernova-origin dust. The findings bolster the RNA-world hypothesis, suggest complex organics formed early on Bennu's parent body, and show preserved presolar grains that escaped alteration for billions of years. "All five nucleobases used to construct both DNA and RNA, along with phosphates, have already been found in the Bennu samples brought to Earth by OSIRIS-REx," said lead scientist Yoshihiro Furukawa of Tohoku University. "The new discovery of ribose means that all of the components to form the molecule RNA are present in Bennu." The findings have been published in three new papers by the journals Nature Geosciences and Nature Astronomy. NASA also published a video on YouTube detailing the discovery.
