Germany's Horst Seehofer promises clarity after hack attack

German Interior Minister Horst Seehofer has pledged to provide clarity on a massive data breach that has shaken Germany's political establishment.

Seehofer told Süddeutsche Zeitung that he would meet the heads of the country's criminal police office (BKA) and cyber defense agency (BSI) again on Monday to find out what they knew about the cyberattack and how they dealt with it.

The interior minister said he would share everything he finds out with the public by the middle of the next week at the latest.

"The public will know everything I know," Seehofer said.

The security breach — one of Germany's biggest cyberattacks — saw personal data and documents from Chancellor Angela Merkel and hundreds of other German politicians and public figures published online.

The interior committee of the German parliament's lower house, the Bundestag, will also meet for a special session on Thursday to discuss the breach.
