TeamViewer Breach: APT29 Cozy Bear Hacks Corporate Network, But Customer Data Safe

TeamViewer’s corporate environment was breached yesterday in a cyberattack allegedly by an APT hacking group. The company assures that customer data remains unaffected. However, their IT security update page is oddly hard to find due to a “noindex” tag.

Hot Take:

Well, it looks like TeamViewer’s corporate environment just got a surprise visit from an APT hacking group. Maybe it’s time to add ‘Cybersecurity 101’ to their onboarding checklist, right after ‘How to Share Your Screen’.

Key Points:

  • TeamViewer’s corporate IT environment was breached by an APT hacking group.
  • No evidence suggests that the product environment or customer data is affected.
  • TeamViewer plans to be transparent but added a tag to their update page.
  • APT29, a Russian hacking group, is suspected to be behind the attack.
  • Security alerts from NCC Group and Health-ISAC warn of active exploitation of TeamViewer.
