DigiNotar BV was a Dutch certificate authority from 1998 to 2011. It was acquired in January 2011 by VASCO and subsequently declared bankrupt in September of the same year. The company was hacked in June 2011 and it issued hundreds of fraudulent certificates, some of which were used for man-in-the-middle attacks on Iranian Gmail users.
