June 28 (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
