  How tensions with Iran could test a new cyber strategy

  Mark Pomerleau In 2018, the Department of Defense began following a new philosophy for cyber operations to better protect U.S. networks and infrastructure. Known as “defend forward,” the approach allows U.S. cyber forces to be active in foreign network outside the United States to either act against adversaries or warn allies of impending cyber activity that they've observed on foreign networks. After the U.S. military killed an Iranian general in a Jan. 2 drone strike and after national security experts said they expect Iran might take some retaliatory action through cyber operations, the specter of increased cyber attacks against U.S. networks puts Cyber Command and its new approach front and center. “This Iran situation today is a big test of the ‘defend forward' approach of this administration,” James Miller, senior fellow at Johns Hopkins Applied Physics Laboratory and former undersecretary of defense for policy, said at a Jan. 7 event hosted by the Council on Foreign Relations. “Will [Cyber Command] take preventative action? Will they do it in a way that our allies and partners support and that can be explained to the public?” While Iran fired several missiles Jan. 7 at a base in Iraq where U.S. troops lived as an initial response to the drone strike, many national security experts expect Iran could continue cyber actions as further retaliation for the strike. Iran could also ratchet up its cyber operations in the United States following the collapse of portions of the 2015 nuclear deal between the United States, Iran and five other nations to curb Iran's nuclear weapons capability in return for sanctions relief. Over the past 12 months, the White House and Congress streamlined many of the authorities used to conduct cyber operations to help cyber forces to get ahead of threats in networks around the world. One such provision in last year's annual defense policy bill provides the Pentagon with the authority to act in foreign networks if Iran, among other named nations, is conducting active, systematic and ongoing campaigns of attacks against the U.S. government or people. Cyber Command declined to comment on what, if anything, they were doing differently since the drone strike. Some experts, however, have expressed caution when assessing how well this defend forward approach has worked thus far given it is still relatively new. “The jury is very much still out here,” Ben Buchanan, assistant professor and senor faculty fellow at Georgetown University, said at the same event. “We don't have a lot of data, there's been a lot of hand-wringing ... about these authorities and about how Cyber Command may or may not be using them. I just don't think we've seen enough to judge whether or not ... [it is] meaningfully changing adversary behavior.” Others have also expressed reservations about how effective Iran can even be in cyberspace toward U.S. networks. “Iran is a capable cyber actor, Iran is a wiling cyber actor. That means Iran will conduct cyberattacks,” said Jacquelyn Schneider, Hoover fellow at the Hoover Institution at Stanford University. “It's not like they have this capability and they've been deterred in the past and maybe now they're going to turn it on. I think they've been trying this entire time.” Complicating matters further could be other actors trying to take advantage of U.S.-Iran imbroglio for their own interests. Priscilla Moriuchi, senior principal researcher and head of nation-state research at threat intelligence firm Recorded Future, said over the past several months, there have been reports of Russian state-affiliated actors hijacking Iranian cyber infrastructure to conduct operations masquerading as Iranians. “That creates its own uncertainty,” she said at the same event. “Another level of potential what we call inadvertent escalation if a country perceives that they are attacked by Iran but in reality, it” wasn't. https://www.fifthdomain.com/dod/2020/01/09/how-tensions-with-iran-could-test-a-new-cyber-strategy/

  Russia says its new weapon is 27 times faster than the speed of sound

  By: Vladimir Isachenkov, The Associated Press MOSCOW — Russia's new strategic weapon has rendered any missile defenses useless at a small fraction of their cost, officials said Thursday. The Avangard hypersonic glide vehicle flies 27 times faster than the speed of sound, making it impossible to intercept, Deputy Prime Minister Yuri Borisov told Russian state television. The new weapon “essentially makes missile defenses useless,” he said. Borisov spoke a day after Russian President Vladimir Putin oversaw what he described as the conclusive successful test of the Avangard and hailed it as a reliable guarantee of Russia's security for decades to come. In Wednesday's test, the weapon was launched from the Dombarovskiy missile base in the southern Ural Mountains. The Kremlin said it successfully hit a practice target on the Kura shooting range on Kamchatka, 3,700 miles away. The Defense Ministry released footage from the test launch, in which a ballistic missile could be seen blasting from a silo in a cloud of smoke, but it hasn't released any images of the vehicle itself. Putin said the Avangard will enter service with the Russian Strategic Missile Forces next year. The test comes amid bitter tensions in Russia-U.S. relations, which have been strained over the Ukrainian crisis, the war in Syria and the allegations of Moscow's meddling in the 2016 U.S. presidential election. Sergei Ivanov, a former Russian defense minister, said in televised comments that the Avangard constantly changes its course and altitude as it flies through the atmosphere. He emphasized that unlike previous nuclear warheads fitted to intercontinental ballistic missiles that follow a predictable trajectory allowing it to calculate the spot where they can be intercepted, the Avangard chaotically zigzags on its path to its target, making it impossible to predict the weapon's location. A smiling Ivanov likened the weapon's flight through the atmosphere to a pebble skipping off the surface of water. Ivanov, who now serves as Putin's adviser, said the Avangard could be fitted to the Soviet-made UR-100UTTKh intercontinental ballistic missile, which is code-named SS-19 Stiletto by NATO. He noted that Russia has a stockpile of several dozen such missiles, which are in a factory-mint condition and not filled with fuel, allowing them to serve for a long time to come. Ivanov added that they could be put in existing silos, sharply reducing the costs of Avangard's deployment. "The Avangard has cost hundreds of times less than what the U.S. has spent on its missile defense," Ivanov said. He noted that Russia began to develop the Avangard after the U.S. started to develop defenses against ballistic missiles. Moscow feared that the U.S. missile shield could erode its nuclear deterrent, and Putin announced in 2004 that Russia was working on a new hypersonic weapon. Ivanov recalled that when Russian officials warned their U.S. counterparts about the new weapon program at the time, American officials were openly skeptical about Russia's ability to carry out its plan. “We aren't involved in saber-rattling, we simply ensured our security for decades to come,” he said. https://www.militarytimes.com/news/your-military/2018/12/27/russia-says-its-new-weapon-is-27-times-faster-than-the-speed-of-sound
