Dutch Agency Broadens Hacking Investigation

The Dutch government said that it was widening its investigation into the hacking of official state Web sites in an attempt to learn whether the private data of Dutch citizens, many of whom file income tax returns online, had also been compromised. The Dutch data protection agency, OPTA, has asked the government security contractor at the center of the controversy, DigiNotar, to report whether the integrity of a special class of digital certificates known as qualified certificates, which guarantee the authenticity of computer users interacting with government computers, had been breached.
