Mermaids UK has apologized for an "inadvertent" data breach which exposed private messages between the charity and the parents of gender variant and transgender children. When data breaches occur, it is often the case that cyberattackers infiltrate internal networks and steal information -- and this data may be published online or sold in underground forums. However, in Mermaids UK's case, the material had simply been uploaded to the web and could be accessed just by typing in "Mermaids" and the UK charity number assigned to the group. In a statement, Mermaids UK called the data breach "inadvertent" and insists there is no evidence of the sensitive material being abused. The charity added that the emails stemmed from a "private user group" and "the information could not be found unless the person searching for the information was already aware that the information could be found." "Mermaids apologizes for the breach," the charity added.
