U.S. last week granted Microsoft's motion that some documents be sealed in a two-year-old lawsuit that accuses the company of when it updated its Windows Genuine Advantage (WGA) antipiracy software via its Windows Update service.
In a deposition filed with Jones three weeks ago, , the director of Microsoft's Genuine Windows group, said that revealing sensitive sections of the WGA software development kit (SDK) would give hackers a field day.
"Public release of the WGA SDK Integration Specifications information would allow hackers to defeat the WGA Validation function by causing WGA to generate false results indicating that the system being tested is genuine, thereby creating great risk of harm to both Microsoft and users of Microsoft's software," Kochis asserted.
By deciphering WGA's error codes and its test protocols, attackers would be able to sidestep the validation process that the technology uses to determine whether a copy of Windows is legitimate, Kochis said.
In turn, that would put users in danger, he said. " users would be at risk because pirated copies of Windows XP often contain unauthorized software that pirates have added to copies of Windows XP that can lead to a corrupted system, a loss of data, or even identity theft," Kochis said.
WGA has a checkered history, and has often from Windows users. In June 2006 it pushed a version of WGA to XP users via Windows Update by tagging it as a "high priority" update that was automatically downloaded and installed to most machines. That event is the one at the center of the current lawsuit.
A year later, a riled thousands of users who were mistakenly fingered for running counterfeit copies of Windows.
The lawsuit, which seeks class-action status, has not yet been scheduled for trial.
In related news this week, in a separate case involving its "Windows " marketing program, Microsoft asked U.S. District Court Judge Marsha Pechman to to use the Windows Update service to distribute a class member notification to nearly 150 million Windows users.
