British Mensa Limited

British Mensa, the society for people with high IQs, suffered a data breach incident after a hack on its website resulted in the theft of members’ personal data.

The incident affected 18,000 members as the stored passwords of Mensa members were not hashed by the society.

The breached information included sensitive information on its members, including payment details, instant messaging conversations, and IQ.
