Cyberattack on Teamviewer by APT29

734After Incident
HIGH-19
TEA001070924
Teamviewer, a German cloud company, confirmed a cyberattack attributed to the Russian hacking group APT29, also known as Cozy Bear and Midnight Blizzard. The attack involved credentials of a standard employee account within Teamviewer's Corporate IT environment. Although the attack was reportedly contained within Teamviewer's internal corporate IT environment without affecting the product environment or customer data, the implications of such a breach by a sophisticated state-backed actor are concerning due to potential access to sensitive corporate information and the risk of further undisclosed exploits.
