Longtime Slashdot reader schwit1 shares a report from Inside Higher Ed: For the first time since he started teaching Welfare Economics and Social Choice Theory nearly two decades ago, Brown University economics professor Roberto Serrano gave his students a take-home midterm this spring. Quite a few students had expressed anxiety about being in a classroom after a gunman killed two students and injured nine in a December mass shooting at Brown, and so "it was appropriate," he said, to allow students to take their exams at home. But by the end of the semester, Serrano regretted the decision. Dozens of students in the class likely used artificial intelligence to cheat and earn perfect or near-perfect scores on their midterm, he said. Serrano in turn made the final exam in-person, which led more than a dozen students to drop the course and even more to fail it. Administrators' response to the widespread cheating event has been "meek," he said, and the incident has raised questions about how universities can -- and should -- respond to AI-enabled cheating at scale. "I am not declaring [the midterm] void for now. I am going to give the class a chance to prove me wrong," he wrote. "That is, if the distribution of the final exam is roughly similar to the distribution of the midterm, I will count the midterm. Otherwise, which is of course what I expect to happen, I will declare the midterm void and reweigh the final accordingly." Serrano heard crickets from his students, but 18 of them subsequently dropped the class. Nine students remained enrolled but did not take the final exam. And Serrano said the results proved him right; three students earned a zero, and the average score on the final was 48.6 percent -- by far a historic low, he said. Previously, the average final exam score had never dropped below 65 percent. Only a few students scored similarly to how they did on the midterm.

Dutch intelligence agencies say Russian hackers have been hijacking unsecured internet-connected cameras, including likely doorbell and security cameras, to spy on NATO military bases and transport routes used to move weapons to Ukraine. "Organisations with IP [internet protocol] cameras on these routes have now been warned so that they could take action," said the AIVD domestic security and MIVD military intelligence agencies. Targeted NATO member states include the Netherlands and Ukraine. The Telegraph reports: While the intelligence agencies did not specify the type of cameras hacked, the doorbell systems are frequently used by people to monitor their property from mobile phones. Hackers then use readily available apps to scan for devices that might be accessible. The Dutch investigation found that many of the cameras were unsecured, and "often have standard passwords, outdated firmware and standard configurations." They said: "When the IP camera is identified, the malicious party can attempt to access the IP camera via the internet. This is often relatively easy, because many IP cameras connected to the internet are insufficiently secure." [...] The practice is now considered easier and cheaper than using drones and satellites to gather intelligence. It also aids operational surprise because most camera owners are blissfully unaware their devices have been penetrated by hackers. Ground-based cameras offer a unique perspective on the terrain, which isn't the case with conventional aerial-based spy kit.

NHTSA is ordering autonomous vehicle developers to explain by the end of the month how they will stop driverless cars from interfering with police, firefighters, and paramedics. TechCrunch reports: [NHTSA Administrator Jonathan Morrison] noted in the letter (PDF) that the agency has "identified a clear pattern of driverless AVs interfering with law enforcement and other first responders," citing instances in which these vehicles drove into active emergency scenes, blocked the paths of ambulances and firefighters, or failed to recognize and respond to basic safety conditions like flashing lights, flares, smoke, fire, and traffic cones. The agency has demanded that AV developers present their "solutions" to this problem by the end of the month. "Let me be clear: the inability to detect and appropriately respond to such situations represents a functional insufficiency," Morrison's letter reads. "Emergency scenes are not rare or extreme 'edge cases.' As such, NHTSA is today issuing a call to action for AV developers and operators to immediately focus their resources on fixing this issue." The agency doesn't explicitly call out any particular company in the letter; however, the details suggest it is directed at robotaxi operators like Waymo. [...] The agency's letter to AV developers doesn't say what the consequences would be if the request is ignored. Nor does it outline what the acceptable solutions would be. But the agency does imply it would hold companies accountable, just as it does human drivers who impede law enforcement. "Every second matters when law enforcement officers, firefighters, or paramedics are answering a call because lives are on the line," the letter states. "That is why human drivers who impede these operations are subject to fines and even jail time." The agency also noted in a press release accompanying the letter that it's making progress on updating Federal Motor Vehicle Safety Standards (FMVSS) requirements, which govern vehicle design and equipment requirements. These proposed changes could help autonomous vehicle companies like Tesla and Zoox, which are developing vehicles without steering wheels, pedals, or other features required on human-driven cars. The agency has already proposed rules that would eliminate the need for windshield wipers, sun visors, defogging systems, and tire placards. The agency released a new 2026 Regulatory Plan and Unified Agenda last week, outlining its proposals.
