  • Computer scientists have proposed a malware prototype that uses inaudible audio signals to communicate, a capability that allows the malware to covertly transmit keystrokes and other sensitive data even when infected machines have no network connection. The proof-of-concept software—or malicious trojans that adopt the same high-frequency communication methods—could prove especially adept in penetrating highly sensitive environments that routinely place an "air gap" between computers and the outside world. Using nothing more than the built-in microphones and speakers of standard computers, the researchers were able to transmit passwords and other small amounts of data from distances of almost 65 feet. The software can transfer data at much greater distances by employing an acoustical mesh network made up of attacker-controlled devices that repeat the audio signals. The researchers, from Germany's Fraunhofer Institute for Communication, Information Processing, and Ergonomics, recently disclosed their findings in a paper published in the Journal of Communications. It came a few weeks after a security researcher said his computers were infected with a mysterious piece of malware that used high-frequency transmissions to jump air gaps. The new research neither confirms nor disproves Dragos Ruiu's claims of the so-called badBIOS infections, but it does show that high-frequency networking is easily within the grasp of today's malware.

    Not event the Sneaker Net is secure. Note to self: surgically remove all microphones and video cams from all systems (just the laptop, I think, but check).

N.S.A. Devises Radio Pathway Into Computers - NYTimes.com - 1 views

  • The National Security Agency has implanted software in nearly 100,000 computers around the world that allows the United States to conduct surveillance on those machines and can also create a digital highway for launching cyberattacks.While most of the software is inserted by gaining access to computer networks, the N.S.A. has increasingly made use of a secret technology that enables it to enter and alter data in computers even if they are not connected to the Internet, according to N.S.A. documents, computer experts and American officials.The technology, which the agency has used since at least 2008, relies on a covert channel of radio waves that can be transmitted from tiny circuit boards and USB cards inserted surreptitiously into the computers. In some cases, they are sent to a briefcase-size relay station that intelligence agencies can set up miles away from the target.
  • The radio frequency technology has helped solve one of the biggest problems facing American intelligence agencies for years: getting into computers that adversaries, and some American partners, have tried to make impervious to spying or cyberattack. In most cases, the radio frequency hardware must be physically inserted by a spy, a manufacturer or an unwitting user.
  • The N.S.A. and the Pentagon’s Cyber Command have implanted nearly 100,000 “computer network exploits” around the world, but the hardest problem is getting inside machines isolated from outside communications.

  • the program, code-named Quantum, has also been successful in inserting software into Russian military networks and systems used by the Mexican police and drug cartels, trade institutions inside the European Union, and sometime partners against terrorism like Saudi Arabia, India and Pakistan, according to officials and an N.S.A. map that indicates sites of what the agency calls “computer network exploitation.”“What’s new here is the scale and the sophistication of the intelligence agency’s ability to get into computers and networks to which no one has ever had access before,” said James Andrew Lewis, the cybersecurity expert at the Center for Strategic and International Studies in Washington. “Some of these capabilities have been around for a while, but the combination of learning how to penetrate systems to insert software and learning how to do that using radio frequencies has given the U.S. a window it’s never had before.”
  • A program named Treasure Map tried to identify nearly every node and corner of the web, so that any computer or mobile device that touched it could be located.
  • Over the past two months, parts of the program have been disclosed in documents from the trove leaked by Edward J. Snowden, the former N.S.A. contractor. A Dutch newspaper published the map of areas where the United States has inserted spy software, sometimes in cooperation with local authorities, often covertly. Der Spiegel, a German newsmagazine, published the N.S.A.'s catalog of hardware products that can secretly transmit and receive digital signals from computers, a program called ANT. The New York Times withheld some of those details, at the request of American intelligence officials, when it reported, in the summer of 2012, on American cyberattacks on Iran.
  • A 2008 map, part of the Snowden trove, notes 20 programs to gain access to big fiber-optic cables — it calls them “covert, clandestine or cooperative large accesses” — not only in the United States but also in places like Hong Kong, Indonesia and the Middle East. The same map indicates that the United States had already conducted “more than 50,000 worldwide implants,” and a more recent budget document said that by the end of last year that figure would rise to about 85,000. A senior official, who spoke on the condition of anonymity, said the actual figure was most likely closer to 100,000.
  • The N.S.A.'s efforts to reach computers unconnected to a network have relied on a century-old technology updated for modern times: radio transmissions.In a catalog produced by the agency that was part of the Snowden documents released in Europe, there are page after page of devices using technology that would have brought a smile to Q, James Bond’s technology supplier.
  • One, called Cottonmouth I, looks like a normal USB plug but has a tiny transceiver buried in it. According to the catalog, it transmits information swept from the computer “through a covert channel” that allows “data infiltration and exfiltration.” Another variant of the technology involves tiny circuit boards that can be inserted in a laptop computer — either in the field or when they are shipped from manufacturers — so that the computer is broadcasting to the N.S.A. even while the computer’s user enjoys the false confidence that being walled off from the Internet constitutes real protection.The relay station it communicates with, called Nightstand, fits in an oversize briefcase, and the system can attack a computer “from as far away as eight miles under ideal environmental conditions.” It can also insert packets of data in milliseconds, meaning that a false message or piece of programming can outrace a real one to a target computer. Similar stations create a link between the target computers and the N.S.A., even if the machines are isolated from the Internet.
  • Computers are not the only targets. Dropoutjeep attacks iPhones. Other hardware and software are designed to infect large network servers, including those made by the Chinese.Most of those code names and products are now at least five years old, and they have been updated, some experts say, to make the United States less dependent on physically getting hardware into adversaries’ computer systems.
  • But the Stuxnet strike does not appear to be the last time the technology was used in Iran. In 2012, a unit of the Islamic Revolutionary Guards Corps moved a rock near the country’s underground Fordo nuclear enrichment plant. The rock exploded and spewed broken circuit boards that the Iranian news media described as “the remains of a device capable of intercepting data from computers at the plant.” The origins of that device have never been determined.

    Even radio transceivers emplanted in USB jacks. So now to be truly secure, we need not only an air gap but also a Faraday cage protecting the air gap.
