A significant data breach has occurred at the European Commission, allegedly perpetrated by the cybercrime group ShinyHunters, with over 350 GB of sensitive data stolen1. The compromised data includes content from mail servers, internal communications systems, databases, and confidential documents. The breach was announced by ShinyHunters on its Tor data leak site, where the group claims to have obtained a substantial amount of sensitive material, including contracts and other confidential information. The European Commission's systems were reportedly vulnerable to the attack, allowing ShinyHunters to extract a large volume of data. This breach matters to cybersecurity practitioners because it highlights the ongoing threat posed by sophisticated cybercrime groups, which can have significant implications for organizations with sensitive data, particularly those in the public sector.
