Exterior view of the building housing Internet security firm DigiNotar in Beverwijk, north-western Netherlands Tuesday Sept. 6, 2001. Dutch prosecutors say they are investigating DigiNotar for possible criminal negligence after it was slow to disclose a hacking incident that compromised dozens of websites and likely helped the Iranian government spy on dissidents for a month. DigiNotar, a subsidiary of Chicago-based Vasco Inc., did not return phone calls seeking comment. Spokesman Ernst Koeman of the Netherlands' national prosecutor's office said Tuesday the investigation is in a preliminary phase. (AP Photo/Peter Dejong) less
