    UAE issues formal request to buy KC-46A tanker, says Boeing

    By: Mike Yeo SINGAPORE – The United Arab Emirates has emerged as a surprise customer for KC-46A Pegasus, having formally made a request to buy the tanker aircraft, according to manufacturer Boeing. Speaking to reporters at a media event on the sidelines of the annual Shangri-La Dialogue regional security summit in Singapore, Jeff Shockey, Boeing's vice president of global sales for defense, space and security, confirmed that the Middle Eastern kingdom had issued a letter of request for three tankers. The UAE now joins the list of potential markets for the KC-46A, alongside other interested parties such as Indonesia, Israel, Norway, Qatar and NATO. Japan has already joined the U.S. Air Force in selecting the KC-46, with a request for four aircraft approved by the U.S. State Department in 2016 with two having already since been contracted through the Foreign Military Sales program. The UAE's request to buy the KC-46A is a surprise, given it currently already operates three Airbus A330 multirole tanker transports. It currently operates about 150 Lockheed Martin F-16E/F Fighting Falcon and French-built Dassault Mirage 2000 fighter jets. It is unclear if the UAE is holding a competitive tender for additional tankers. Airbus referred Defense News to the customer when asked if the European manufacturer has received interest from the UAE about additional tankers. https://www.defensenews.com/global/mideast-africa/2019/05/31/uae-issues-formal-request-to-buy-kc-46a-tanker-says-boeing

    US Spies Want to Know How to Spot Compromised AI

    BY DAVE GERSHGORN What if you were training an AI, and an adversary slipped a few altered images into its study set? The US government's research arm for intelligence organizations, IARPA, is looking for ideas on how to detect “Trojan” attacks on artificial intelligence, according to government procurement documents. Here's the problem the agency wants to solve: At a simple level, modern image-recognition AI learns from analyzing many images of an object. If you want to train an algorithm to detect pictures of a road signs, you have to supply it with pictures of different signs from all different angles. The algorithm learns the relationships between the pixels of the images, and how the structures and patterns of stop signs differ from those of speed-limit signs. But suppose that, during the AI-training phase, an adversary slipped a few extra images (Trojan horses) into your speed-limit-sign detector, ones showing stop signs with sticky notes on them. Now, if the adversary wants to trick your AI in the real world into thinking a stop sign is a speed-limit sign, it just has to put a sticky note on it. Imagine this in the world of autonomous cars; it could be a nightmare scenario. The kinds of tools that IARPA (Intelligence Advanced Research Projects Activity) wants would be able to detect issues or anomalies after the algorithm has been trained to recognize different objects in images. This isn't the only kind of attack on AI that's possible. Security researchers have also warned about inherent flaws in the way artificial intelligence perceives the world, making it possible to alter physical objects like stop signs to make AI algorithms miscategorize them without ever messing with how it was trained, called “adversarial examples.” While neither Trojan attacks nor the adversarial examples are known to have been used by malicious parties in the real world, researchers have said they're increasingly possible. IARPA is looking at a short timeline as well, expecting the program to conclude after a maximum of two years. https://www.defenseone.com/technology/2018/12/us-spies-want-know-how-spot-compromised-ai/153826
