Hacker finally publishes notorious Apple Wi-Fi attack
682316
(InfoWorld) - More than a year after claiming to have found a way to take over a Macintosh computer using a flaw in the system's wireless card, David Maynor has published details of his exploit. The details were included in a paper published in the September issue of Uninformed.org, an online hacking magazine. The lengthy paper describes how to run unauthorized software on a Macintosh by taking advantage of a flaw in Apple's AirPort wireless drivers. Apple patched the bug in September 21 without crediting Maynor for discovering the problem. Instead,Â Apple's engineers found the bug during an internal audit, the company said. Maynor and researcher Jon Ellch first described this type of problem during an August 2006 presentation at the Black Hat security conference in Las Vegas. He was widely criticized by the Apple community for failing to back up his claims with technical details and for presenting a video demonstration that used a third-party wireless card instead of the one that ships with the Mac. On Tuesday, Maynor said that at the time of the Black Hat demonstration, he had found similar wireless bugs in a number of wireless cards, including Apple's AirPort and that he had been told to use the third-party card in the video because it was deemed "the least offensive to people." So why publish the Mac hack now? Maynor said that he had been under a nondisclosure agreement, which had previously prevented him from publishing details of the hack. The security researcher wouldn't say who his NDA was with, but that agreement is no longer in force, allowing him to talk about the exploit. "I published it now because I can publish it now," he said. By going public with the information, Maynor hopes to help other Apple researchers with new documentation on things like Wi-Fi debugging and the Mac OS X kernel core dumping facility. "There's a lot of interesting information in the paper that, if you're doing vulnerability research on Apple, you'd find useful." Maynor will soon publish a second paper on Uniformed.org explaining how to write software that will run on a compromised system, he said. As for his detractors, who will say that this disclosure comes too late, Maynor says he just doesn't care what they think. "Let them tear me apart all they want but at the end of the day the technical merit of the paper will stand on its own."

If criminals were to target unsecured wireless routers, they could create an attack that could piggyback across thousands of Wi-Fi networks in urban areas like Chicago or New York City, according to researchers at Indiana University.The researchers estimate that a Wi-Fi attack could take over 20,000 wireless routers in New York City within a two-week period, with most of the infections occurring within the first day.&quot;The issue is that most of these routers are installed out of the box very insecurely,&quot; said Steven Myers, an assistant professor at Indiana University, who published the paper in November, along with researchers from the Institute for Scientific Interchange in Torino, Italy,The researchers theorize that attack would work by guessing administrative passwords and then instructing the routers to install new worm-like firmware, which would in turn cause the infected router to attack other devices in its range.Because there are so many closely connected Wi-Fi networks in most urban areas, the attack could hop from router to router for many miles in some cities.The team used what is known as the Susceptible Infected Removed (SIR) model to track the growth of this attack. This methodology is typically used to estimate things like influenza outbreaks, but it has also been used to predict things like computer virus infections, Myers said.Although the researchers did not develop any attack code that would be used to carry out this infection, they believe it would be possible to write code that guessed default passwords by first entering the default administrative passwords that shipped with the router, and then by trying a list of one million commonly used passwords, one after the other. They believe that 36 percent of passwords can be guessed using this technique.Even some routers that use encryption could be cracked, if they use the popular WEP (Wired Equivalent Privacy) algorithm, which security experts have been able to crack for years now. Routers that were encrypted using the more-secure WPA (Wi-Fi Protected Access) standard were considered impossible to infect, Myers said.Myers&#39; model is based on data compiled from the Wireless Geographic Logging Engine (WiGLE), a volunteer-run effort to map Wi-Fi networks around the world, which has over 10 million networks in its database.Using this data, they were able to map out large networks of made out of Wi-Fi routers that were each no more than 45 meters (49 yards) from the network -- in other words, close enough for an infection to spread. The largest such network in New York included 36,807 systems; in Boston it was 15,899; and in Chicago: 50,084.Because New York is such a dense city with a relatively low percentage (25.8 percent, according to the researchers) of encrypted routers, it was particularly susceptible to this type of attack. San Francisco, on the other hand, where 40.1 percent of routers are encrypted and which had a lower density of routers was less susceptible.Myers says that because the attack would be technically complex, he doubts that criminals will attempt it any time soon. There are simply too many other, easier ways to take over computers, he said.Still, he thinks hardware makers should take note. &quot;The bigger point for developers and people making wireless information technology is to realize that there are serious security issues.&quot;
