A security researcher has released a proof-of-concept program that hackers could use to exploit Windows Vista digital rights management processes to hide malware.

Alex Ionescu claims to have developed the program — D-Pin Purr v1.0 — that will arbitrarily enable and disable protected processes in Vista, Microsoft's latest operating system.

Fraser Howard, a principal virus researcher at security vendor Sophos, told ZDNet UK that the program looks feasible. "I have not confirmed it, but I have little doubt it will work as intended [to remove protection]," said Howard. "This should mean it is perfectly possible to add protection to processes as well."

The source code for the program is not available. Should the source code of the program become available to hackers, this could mean that other processes would not be able to properly "inspect" the hacked protected process, according to Howard.
