500 Email Addresses Accidentally Leaked in the Email CC line
Take action: Incidents like this stem from an effort to "save money" by using an email client as a mass-notification tool, and the tired operator didn't pay attention. Just limit the number of people you can place in the CC and BCC lines to a reasonable amount and use a service for mass-notifications.

Approximately 500 e-mail addresses belonging to pensioners of the Dutch ABP pension fund were inadvertently exposed due to a human error in the e-mail sending process.
The addresses were mistakenly entered in the CC (carbon copy) line instead of the intended BCC (blind carbon copy) line, which resulted in the visibility of all recipients' e-mail addresses.
ABP, which manages pensions for individuals working in education and administration, promptly reported the data breach to the data protection authority and has taken measures to inform all those affected by the incident.
