(Reuters) - German software company Teamviewer said on Friday it was the victim of a cyberattack earlier this week and accused the Russian hacker group APT29 of being behind the attack.
The group, also known as "Cozy Bear" or Midnight Blizzard, is alleged by Western intelligence to act on behalf of Russia's foreign spy agency.
In March, Alphabet's Mandiant cyber unit said it had caught the hacking group trying to trick "key German political figures" into opening a phishing email.
The German software company, which specialises in cloud-based technologies, said in a statement that the group gained access to its corporate IT environment but not to its product environment or customer data on Wednesday.
Shares in the company were down 10% at 1152 GMT, on track for their worst day since November 2023
