U.S. intelligence officials believe that Iran is trying to sabotage former President Trump's presidential campaign through online influence operations, according to a press briefing on Monday. Speaking to reporters, an official with the Office of the Director of National Intelligence (ODNI) said U.S. spy agencies "observed Tehran working to influence the presidential election," likely because Iranian leaders want to avoid increased tensions with the U.S. The official didn't directly say that Iran was trying to undermine Trump, but that American spies "haven't observed a shift in Iran's preferences" since 2020, meaning that Iran was still targeting Trump. During the briefing, an intelligence official also said Iran is utilizing "vast webs of online personas and propaganda mills to spread disinformation," in addition to different online campaigns. U.S. intelligence officials believe Iran is meddling in the 2024 election. Earlier in July, Tehran was accused of a separate plot to kill Trump after a gunman shot the former president at a rally in Butler, Pennsylvania, on July 13.

Yesterday evening, the Washington Post broke the blockbuster news that FBI agents who searched former President Trump's Mar-a-Lago residence on Monday were looking for "nuclear documents," a phrase that immediately set off alarms inside national security circles. The nation's nuclear systems and plans are considered among the most sensitive and most narrowly known secrets. Trump denied the report, calling the "nuclear weapons issue" a "hoax." But assuming the Post's reporting is correct, what could such a vague phrase as "nuclear documents" mean, and what could we learn about such a category? Broadly speaking, the US intelligence and defense communities would possess four different categories of files that might be considered "nuclear documents": nuclear weapon science and design; other countries' nuclear plans, including the nuclear systems and command of allied nations (UK, France) and adversaries (Russia, China, North Korea, Iran), as well as countries whose nuclear programs exist in a more gray zone (Israel, India, Pakistan); details on the United States' own nuclear weapons and deployments; and details on US nuclear command & control procedures, known in Pentagon parlance as NC2.

From cyber operations to disinformation, artificial intelligence extends the reach of national security threats that can target individuals and whole societies with precision, speed, and scale. As the US competes to stay ahead, the intelligence community is grappling with the fits and starts of the impending revolution brought on by AI. The US intelligence community has launched initiatives to grapple with AI's implications and ethical uses, and analysts have begun to conceptualize how AI will revolutionize their discipline, yet these approaches and other practical applications of such technologies by the IC have been largely fragmented. As experts sound the alarm that the US is not prepared to defend itself against AI by its strategic rival, China, Congress has called for the IC to produce a plan for integration of such technologies into workflows to create an "AI digital ecosystem" in the 2022 Intelligence Authorization Act. The term AI is used for a group of technologies that solve problems or perform tasks that mimic humanlike perception, cognition, learning, planning, communication, or actions.

Fox News correspondent David Spunt joins'Special Report with Bret Baier' to discuss fake videos that could'stir up trouble' with national security As tensions continue to rise in Ukraine and Russia, U.S. intelligence officials are on the watch for manipulated video and audio that could result in multiple cases of misinformation. The FBI continues to wage a campaign against illegal deepfakes, as the technology continues to improve. "Audio, video, text and images that are created to show something that didn't necessarily happen, or never occurred," FBI Cyber Division Unit Chief Pranav Shah said of deepfakes. Shah tells FOX News the technology, once reserved for cyber wizards, is becoming more user-friendly. He says it is getting easier to make these digital deceptions, and they aren't always illegal.

Nasa has announced that it has found evidence of flowing water on Mars. Scientists have long speculated that Recurring Slope Lineae -- or dark patches -- on Mars were made up of briny water but the new findings prove that those patches are caused by liquid water, which it has established by finding hydrated salts. Several hundred camped outside the London store in Covent Garden. The 6s will have new features like a vastly improved camera and a pressure-sensitive "3D Touch" display

In an announcement, IARPA officials laid out the project's goals: "The DIVA program will produce a common framework and software prototype for activity detection, person/object detection and recognition across a multicamera network," IARPA officials wrote. "The impact will be the development of tools for forensic analysis, as well as real-time alerting for user-defined threat scenarios." In other words: the system should be able to identify suspicious behavior in real-time. One of the problems with existing systems is that they can identify individual people or objects, but not many of them at the same time, or the complex interactions between them. The DIVA system as it is proposed would be able to identify certain types of movements like a person carrying a firearm, two people exchanging an object, or someone walking up and abandoning a potentially dangerous object on the street.
