US Military Disables Ad Trackers On Devices To Protect Troops

2 months ago
Slashdot reader DeanonymizedCoward writes: Reuters reports that the US Military is disabling ad tracking on devices, to prevent adversaries from buying publicly-available tracking data to assist in targeting troops. Military officials say that they have disabled trackers on a variety of computers and mobile devices, according to letters released on Friday by Sen. Ron Wyden, and following reports that commercially-available tracking data has been used to target troops in the Middle East.... Wyden said in a statement that it was clear that the military's efforts "have not been effective at neutralizing this threat." U.S. Representative Pat Harrigan, a North Carolina Republican, said that U.S. enemies "should not be able to pull out a credit card and buy information that helps them track American troops." Rep. Harrigan remains silent as to the larger question of whether the general public should be able to pull out a credit card and buy information that helps them track anyone they please. "The Pentagon said in an email it would respond to the lawmakers directly," Reuters reports: The Army said in a statement that advertising IDs had been blocked on Windows computers "since before 2021" but that Android and Apple mobile devices had only had it disabled by default "since at least February 2026...." The effort to reduce the location data generated by smartphones comes as military officials weigh increasingly strict restrictions on phone use overall. In July, Reuters reported that some deployed personnel in the Middle East could be ordered to surrender their phones amid concerns that mobile videos they were posting to the internet were helping Iran target American bases in the region.

Where a Massive Solar Storm Could Take Down the US Power Grid for Millions

2 months ago
A new study published Friday in AGU Advances "depicts the most advanced picture yet of how a rare but massive solar storm could affect some US industries and electric systems more than others," reports CNN. "During a 250-year solar storm, the East Coast would have widespread potential for grid failure." Researchers modeled what a Carrington Event — a 1-in-150-year geomagnetic storm or even rarer — could mean for the modern day. They estimate the US economy would lose about $1.5 billion to $2 billion per day from direct and indirect costs, as millions of people face power outages. The findings show the most vulnerable areas are the Northeast and the Northern Plains, especially locations at higher latitudes. No one knows when the next big storm will hit. While the most severe geomagnetic storms are labeled as once-in-a-century or rarer, these events don't follow a fixed schedule. "That timing only averages out on very long timescales," said Anna Kelbert, a geophysicist at the Harvard-Smithsonian Center for Astrophysics, who was not involved in the study but previously studied solar storm effects on power grids. "The event can occur at any time, as soon as a week from now, or centuries later...." [Shawn Dahl, service coordinator at the Space Weather Prediction Center operated by the National Oceanic and Atmospheric Administration in Boulder, Colorado], said the sun is now coming down from a period of heightened activity, which is also when some of the biggest storms to hit Earth have occurred in the past. "We still need a lot of work to be ready...." "We haven't really seen events like this size in the modern era, where we've had all of this high technology and we've had the power grid of this size," said Ed Oughton, researcher at George Mason University and lead author of the new study... Because the US grid's actual structure is proprietary for security reasons, the team used engineering models to create various network and transformer setups including the 10,464 substations and 16,256 transmission lines found across the country... The grid structure also contributes to higher risk in some areas. For instance, the eastern US is linked together in a single grid interconnection. A voltage issue in Maine, if not isolated early, could cascade through the grid to Washington, DC. The West works similarly, whereas the Texas interconnection operates mostly within the state... Power is restored over time depending on any alternative electrical paths that could bypass the substation or availabilities of spare transformers, for instance. "This nationwide analysis shows that we are currently ill-prepared to face a major magnetic storm, and that the societal impacts would be catastrophic," Kelbert said. "The study estimates power disruptions for 5.1 million people and 135,000 businesses," according to the article, and "The outages could last from hours to days to weeks depending on the damage and resources available to get back online, said Oughton."
