Security Measures and Response

TeamViewer’s swift response to the incident involved immediate remediation measures and the establishment of additional protection layers.

The company reports no suspicious activity in its internal corporate IT environment since the attack was blocked.

The investigation revealed that the threat actor leveraged a compromised employee account to access the internal corporate IT environment.

The attackers copied employee directory data, including names, corporate contact information, and encrypted employee passwords.

However, Microsoft’s cyber security experts have mitigated the risk associated with these encrypted passwords.

TeamViewer has since hardened its employee authentication procedures and implemented stronger protection layers.

The company has also rebuilt its internal corporate IT environment to ensure a fully trusted state.

Despite concluding the main investigation phase, TeamViewer remains vigilant.

The company monitors the situation closely and maintains a robust security posture.

“Security remains core to our DNA, and we will continue to invest in our best-in-class cyber security posture as we have done in recent years,” the statement reads.
