TeamViewer Confirms “Irregularity”, Denies User Information Breach

As this publication reported earlier today, TeamViewer, the popular remote computer service, was reportedly breached by Russian cyber threat actor APT-29. TeamViewer has now responded to the claims on Mastodon:

On Wednesday, 26 June 2024, our security team detected an irregularity in TeamViewer’s internal corporate IT environment. We immediately activated our response team and procedures, started investigations together with a team of globally renowned cyber security experts and implemented necessary remediation measures.

TeamViewer’s internal corporate IT environment is completely independent from the product environment. There is no evidence to suggest that the product environment or customer data is affected. Investigations are ongoing and our primary focus remains to ensure the integrity of our systems.”

This is developing.
