Kaspersky Lab said it believed the attack was designed to spy on its newest technologies.
It said the intrusion involved up to three previously unknown techniques.
The Russian firm added that it was continuing to carry out checks, but believed it had detected the intrusion at an early stage.
Although it acknowledged that the attackers had managed to access some of its files, it said that the data it had seen was “in no way critical to the operation” of its products.
“Spying on cybersecurity companies is a very dangerous tendency,” said the company’s chief executive Eugene Kaspersky.
