TL;DR:
The European Commission is investigating a breach after finding evidence that its mobile device management platform was hacked. The Commission said on Friday that it detected traces of a cyberattack targeting infrastructure that manages its staff’s mobile devices.
While the attackers may have accessed some staff members’ personal information, including names and phone numbers, the Commission has not yet found evidence that their mobile devices were compromised. - BLEEPING COMPUTER
