Security Update – June 28, 2024, 12:10 a.m. CEST
A task force of TeamViewer’s security team and global cybersecurity experts worked 24/7 to investigate the incident. We are in contact with threat intelligence providers and authorities.
On Wednesday, June 26, an attack occurred via the login credentials of a standard employee account within our Corporate IT environment. Thanks to continuous monitoring, our teams identified suspicious behavior and took immediate action. The attack is attributed to APT29 / Midnight Blizzard and was limited to the Corporate IT environment; no access was gained to our product environment or customer data.
Our best-practice architecture ensures strict separation of Corporate IT, production environment and the TeamViewer connectivity platform, preventing unauthorized access and movement. This separation is part of our “defense in-depth” strategy.
Security is of utmost importance to us and we communicate transparently to stakeholders. We continue to post updates in our Trust Center and expect the next update late today CEST.
