The United States is engaged in an international race to develop both cyberweapons and cyberdefenses. Thousands of daily attacks on federal and private computer systems in the United States, some malicious and some testing for weak points in the U.S.’s firewalls, have prompted the Obama administration to review the nation’s strategy. Efforts include developing a highly classified replica of the Internet of the future to simulate what would be needed for the country’s enemies to shut down power stations, telecommunications, and aviation systems. Obama is expected to propose a significantly larger cyberdefensive effort, including the expansion of a $17 billion, five-year program approved by Congress last year, as well as an end to the bureaucratic battle over who is responsible for defending the country’s cyberinfrastructure. However, Obama is not expected to discuss the U.S.’s cyberoffensive capabilities, which has been a major investment area for the nation’s intelligence agencies, as many of these cyberweapons remain classified. The White House declined to comment on whether Obama supports or opposes the use of U.S. cyberweapons. Some exotic cyberweapons under consideration would enable a military programmer to enter a computer server in Russia or China and destroy a botnet, or activate malicious code that is secretly embedded on computer chips when manufactured, enabling the U.S. to take control of an enemy’s computer system.

A scan of the Internet by Columbia University researchers searching for vulnerable embedded devices has found that nearly 21,000 routers, Webcams, and VoIP products are vulnerable to remote attack. They say there could be as many as 6 million vulnerable devices on the Internet. The scan also found that the devices’ administrative interfaces are viewable from anywhere on the Internet, and their owners have not changed the devices’ passwords from the manufacturer’s default. The study scanned networks belonging to the largest Internet service providers (ISPs) in North America, Europe, and Asia, and vulnerable devices were found in significant numbers in all parts of the world. Since starting the project last December, the researchers have scanned 130 million IP addresses and found nearly 300,000 devices whose administrative interfaces were remotely accessible from anywhere on the Internet. Devices with default passwords are most vulnerable, but others are theoretically vulnerable to brute-force password-cracking attacks. The researchers have provided ISPs with their findings, but Columbia professor Salvatore Stolfo says product manufacturers are the real culprits. He says that they need to hide their administrative interfaces by default and give customers clear instructions on how to alter the configuration to protect themselves. Stolfo also says that vendors should be more vocal in encouraging customers to change default passwords.

The Perception-on-Purpose (POP) project is an effort by European researchers to develop technology enabling a robot to integrate visual and audio data to facilitate purposeful perception. “It is not that easy to decide what is foreground and what is background using sound alone, but by combining the two modalities–sound and vision–it becomes much easier,” says project coordinator Radu Horaud. “If you are able to locate 10 sound sources in 10 different directions, but if in one of these directions you see a face, then you can much more easily concentrate on that sound and throw out the other ones.” The researchers followed this strategy in their development of algorithms that allowed their robot, Popeye, to reliably identify speakers. “Most often, sound research is conducted in specialized labs, with arrays of microphones and a very controlled acoustic environment,” Horaud says. “But we integrated our two microphones and two cameras onto the head of our Popeye. The idea is to have an agent-centered cognitive system.” Horaud believes there is a link between multi-sensory perception and cognition, and that some modern artificial intelligence applications are constrained by their inability to learn from their environment.
